Dear Shareholder

[PHOTO OF TIMOTHY SCHWERTFEGER APPEARS HERE]

Wealth takes a lifetime to build. Once achieved, it should be preserved.

It is a pleasure to report to you on the performance of the Nuveen California
Municipal Bond Funds. Both funds performed well over the past six months,
rewarding investors with attractive tax-free income, consistent performance and
capital preservation.

For the 12 months ended August 31, 1997, the uninsured California fund provided
Class A shareholders with a total return on net asset value of 9.25%, outpacing
the average return of 8.98% for its peer group, the Lipper California Municipal
Bond Fund Category. The insured California fund provided Class A shareholders
with an annual total return of 8.26%, trailing its Lipper peer group average of
8.78%. The fund, which has a shorter duration than its peers, will experience
subdued performance in declining interest rate environments and enhanced
performance in rising rate environments. Both funds continued to provide
consistent income, and each fund experienced an increase in the monthly dividend
during the period.

This performance was achieved in an environment of periodic interest rate
volatility. Positive news on the inflation front helped soften the effects of a
hike in short-term interest rates by the Federal Reserve Board in late March.
After tightening short-term interest rates by 0.25%, the Federal Reserve
demonstrated its confidence in the economy's path by maintaining the status quo
at subsequent meetings.

So far in 1997, investors have focused their attention on fiscal issues such as
the federal budget accord and tax cut measures, including a reduction in the
capital gains tax. The economy continued to experience record expansion and the
lowest unemployment rates in almost two decades, a combination that in the past
has predictably been accompanied by an increase in inflation. Current
conditions, however, give every indication that inflation is under control.

Nuveen's financial products and services continue to evolve as we extend our
commitment to helping prudent investors achieve their investment goals. In
addition to our 35 municipal mutual funds, Nuveen now offers a variety of other
products and services designed for the distinct needs of investors who rely on
their investment portfolios as their principal source of income and financial
security. We recently celebrated the successful first year of our high-
performing Nuveen Growth and Income Stock Fund, as well as two new balanced
stock and bond funds. We have also expanded our private asset management service
by acquiring Rittenhouse Financial Services, a well-respected provider of growth
investment management services.

Nuveen prides itself on helping more than 1.3 million investors achieve their
financial goals by providing quality investment solutions that withstand the
test of time. We thank you for your confidence in Nuveen and our family of
investments, and we look forward to reporting to you again in six months.



Sincerely,

Answering Your Questions


Portfolio Manager Steve Krupa talks about the municipal bond market and offers
insights into the factors that affected fund performance over the past year.

What key economic and market factors affected the funds' performance over the
past year?

The combination of strong economic growth and low inflation has led to slightly
falling bond yields over the past year. Periodic volatility in the bond market
created a positive environment for the funds, providing us with a number of
opportunities to purchase attractive bonds at discounts during brief declines in
the market. The market also experienced a significant tightening of credit
spreads during the year, meaning that the difference in the yields of high-
quality and low-quality bonds was gradually reduced to the smallest levels we've
seen in many years. This allowed us to purchase very high quality bonds for the
portfolios without sacrificing much yield.

The California economy continues to recover from the national and state
recessions experienced in the early 1990s, as evidenced by the construction boom
and labor shortages throughout the state. The California bond market also
performed well, due in part to the tight supply levels experienced over the last
year.

Given these market conditions, 
how have the funds performed?

As Tim mentioned in his letter to shareholders, both funds performed well during
the one-year period ended August 31, 1997. In addition to strong total returns,
the

"In addition to strong total returns, the funds continued to produce consistent
dividends and attractive yields."

funds continued to produce consistent dividends and attractive yields. For Class
A shares, the uninsured California fund generated an annual tax-free yield of
4.45%, and the insured California fund generated a 4.19% annual tax-free yield.
Investors in the 37.5% combined state and federal income tax bracket would have
had to earn at least 7.12% and 6.70%, respectively, on taxable alternatives to
equal these yields on an after-tax basis.

What strategies did you use to add value?

With the tight credit spreads we have seen this year, we took advantage of the
opportunity to improve the credit quality of the uninsured fund without
sacrificing much yield. As always, we utilized our value approach in seeking
bonds that were undervalued by the market. We purchased several bonds that later
experienced significant increases in value when they were refunded by the issuer
in advance of their call date. In addition, we sought higher yields on
investment-grade quality bonds from issuers in new and growing areas of the
state, finding good value in bonds from Rancho Cucamonga, a rapidly growing area
due east of the midpoint between Los Angeles and San Diego.

What is your outlook for the municipal market?

As long as interest rates remain relatively stable, we foresee no major supply
changes in the national municipal bond market. New issuance will likely expand
somewhat as the

4
<PAGE>
 
economy continues to grow. However, if the volatility in the equity market
continues at current levels, we expect demand for bonds to grow as shareholders
move some of their assets from stocks into bonds.

We also anticipate continued strength in the California bond market, and in the
state economy overall. While national supply levels continue to grow slowly, we
expect that California municipal bond issuance will expand more rapidly in the
coming months.

What strategies will you employ in the coming year?

We expect the California bond market to offer a number of opportunities in the
coming year. We plan to capitalize on the supply of new issues coming to market,
as well as new regional growth areas throughout the state. In addition, we will
seek value in larger issues that can sometimes overwhelm the market and
temporarily reduce prices. With credit spreads at such tight levels, we will
also focus on trying to improve the credit quality of the uninsured fund. And,
as always, we will continue to utilize our diligent research team to find bonds
that are presently undervalued by the market.

     the period ending August 31, 1997, by Morningstar Inc., an independent
     mutual fund rating service. The fund was compared with 1,354 municipal bond
     funds for the three-year period, 654 funds for the five-year period and
     316 funds for the 10-year period. The top 10% of funds in the category
     receive five stars, and the next 22.5% of funds receive four stars.

     actual for the period since class inception; returns prior to class
     inception are Class R Share returns adjusted for differences in sales
     charges and expenses, which are primarily differences in distribution and
     service fees. Class A Shares have a 4.2% maximum sales charge. Class B
     Shares have a CDSC that begins at 5% for redemptions during the first year
     after purchase and declines periodically to 0% over the following five
     years, which is not reflected in the return figures. Class C Shares have a
     1% CDSC for redemptions within one year which is not reflected in the 
     one-year total return.

Notes to Financial Statements (Unaudited)

1. General Information and Significant Accounting Policies
The Nuveen Flagship Multistate Trust II (the "Trust") is an open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust comprises the Nuveen California Municipal Bond Fund ("California") and the
Nuveen California Insured Municipal Bond Fund ("California Insured")
(collectively, the "Funds"), among others. The Trust was organized as a
Massachusetts business trust on July 1, 1996.

The John Nuveen Company (Nuveen), parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Funds, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business
on January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds
in December, 1996.

After the close of business on January 31, 1997, California and California
Insured were renamed and reorganized into the Trust. Prior to the
reorganization, California (formerly Nuveen California Tax-Free Value Fund) and
California Insured (formerly Nuveen California Insured Tax-Free Value Fund)
were each a series of the Nuveen California Tax-Free Bond Fund, Inc., an 
open-end diversified management investment company.

Each Fund seeks to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
generally accepted accounting principles.

Securities Valuation
The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Trustees. When price
quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.

Securities Transactions
Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject
to market fluctuation during this period. The Funds have instructed the
custodian to segregate assets in a separate account with a current value at
least equal to the amount of their when-issued and delayed delivery purchase
commitments. At August 31, 1997, California and California Insured had
outstanding purchase commitments of $4,900,908 and $2,405,110, respectively.

                                               August 31, 1997 Semiannual Report
Interest Income
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt
securities when required for federal income tax purposes.

Dividends and Distributions to Shareholders
Tax-exempt net investment income is declared as a dividend monthly and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryovers.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary net taxable income from investment
transactions, where applicable.

Income Taxes
Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Funds
currently consider significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, each Fund 
intends to satisfy conditions which will enable interest from municipal
securities, which is exempt from regular federal and California state personal
income taxes, to retain such tax-exempt status when distributed to the
shareholders of the Funds. Net realized capital gain and market discount
distributions are subject to federal taxation.

Insurance
California Insured invests in municipal securities which are either covered by
insurance or backed by an escrow or trust account containing sufficient U.S.
Government or U.S. Government agency securities, both of which ensure the timely
payment of principal and interest. Each insured municipal security is covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
Such insurance does not guarantee the market value of the municipal securities
or the value of the Fund's shares. Original Issue Insurance and Secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Fund ultimately disposes of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue Insurance or
Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only while the municipal securities are held by
the Fund. Accordingly, neither the prices used in determining

31
<PAGE>

Notes to Financial Statements (Unaudited) - continued
 
the market value of the underlying municipal securities nor the net asset value
of the Fund's shares include value, if any, attributable to the Portfolio
Insurance. Each policy of the Portfolio Insurance does, however, give the Fund
the right to obtain permanent insurance with respect to the municipal security
covered by the Portfolio Insurance policy at the time of its sale.

Flexible Sales Charge Program
Each Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
buy may be subject to a 1% contingent deferred sales charge ("CDSC") if
redeemed within 18 months of purchase. Class B Shares are sold without a sales
charge but incur annual 12b-1 distribution and service fees. An investor
purchasing Class B Shares agrees to pay a CDSC of up to 5% depending upon the
length of time the shares are held by the investor (CDSC is reduced to 0% at the
end of six years). Class B Shares convert to Class A Shares eight years after
purchase. Class C Shares are sold without a sales charge but incur annual 12b-1
distribution and service fees. An investor purchasing Class C Shares agrees to
pay a CDSC of 1% if Class C Shares are redeemed within one year of purchase.
Class R Shares are not subject to any sales charge or 12b-1 distribution or
service fees. Class R Shares are available for purchases of over $1 million and
in other limited circumstances.

Derivative Financial Instruments
The Funds may invest in certain derivative financial instruments including
futures, forward, swap, option contracts, and other financial instruments with
similar characteristics. Although the Funds are authorized to invest in such
financial instruments, and may do so in the future, they did not make any such
investments during the six months ended August 31, 1997.

Expense Allocation
Expenses of each Fund that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Use of Estimates
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period.

6. Management Fee and Other Transactions with Affiliates
Under the Trusts' investment management agreement with the Adviser, each Fund
pays an annual management fee, payable monthly, at the rates set forth below
which are based upon the average daily net asset value of each Fund:
<TABLE>

For the first $125 million                                           .5500 of 1%
For the next $125 million                                            .5375 of 1
For the next $250 million                                            .5250 of 1
For the next $500 million                                            .5125 of 1
For the next $1 billion                                              .5000 of 1
For net assets over $2 billion                                       .4750 of 1
- --------------------------------------------------------------------------------
</TABLE>

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Trust pays no
compensation directly to its Trustees who are affiliated with the Adviser or to
its officers, all of whom receive remuneration for their services to the Trust
from the Adviser.

The Adviser has agreed to waive part of its management fees or reimburse certain
expenses of each Fund in order to limit total expenses to .75 of 1% of the
average daily net asset value of California and .975 of 1% of the average daily
net asset value of California Insured, excluding any 12b-1 fees applicable to
Class A, B and C Shares. The Adviser may voluntarily reimburse additional
expenses from time to time, which may be terminated at any time at its
discretion.

During the six months ended August 31, 1997, the Distributor collected sales
charges on purchases of Class A Shares of approximately $97,300 and $149,300 for
California and California Insured, respectively, of which approximately $83,500
and $126,800, respectively, were paid out as concessions to authorized dealers.
The Distributor also received 12b-1 service fees on Class A Shares,
substantially all of which were paid to compensate authorized dealers for
providing services to shareholders relating to their investments.

During the six months ended August 31, 1997, the Distributor compensated
authorized dealers directly with approximately $48,500 and $44,900 in commission
advances at the time of purchase for California and California Insured,
respectively. To compensate for commissions advanced to authorized dealers, all
12b-1 service fees collected on Class B Shares during the first year following a
purchase, all 12b-1 distribution fees on Class B Shares, and all 12b-1 service
and distribution fees on Class C Shares during the first year following a
purchase are retained by the Distributor. During the six months ended August 31,
1997, the Distributor retained approximately $4,900 and $6,900 in such 12b-1
fees for California and California Insured, respectively. The remaining 12b-1
fees charged to the Funds were paid to compensate authorized dealers for
providing services to shareholders relating to their investments.

Dear Shareholder

Chairman of the Board

Wealth takes a lifetime 
to build. Once achieved, 
it should be preserved.


It is a pleasure to report to you on the performance of the Nuveen Flagship
Connecticut Municipal Bond Fund. The fund performed well over the past six
months, rewarding investors with attractive tax-free income, consistent
performance and capital preservation.

For the 12 months ended August 31, 1997, the fund provided Class A shareholders
with a total return on net asset value of 8.84%, outpacing the average return on
net asset value of 8.38% for the Lipper Connecticut Municipal Bond Category. The
fund was ranked among the top quartile of funds in this peer group.

This strong performance was achieved in an environment of periodic interest rate
volatility. Positive news on the inflation front helped soften the effects of a
hike in short-term interest rates by the Federal Reserve Board in late March.
After tightening short-term interest rates by 0.25%, the Federal Reserve
demonstrated its confidence in the economy's path by maintaining the status quo
at subsequent meetings.

So far in 1997, investors have focused their attention on fiscal issues such as
the federal budget accord and tax cut measures, including a reduction in the
capital gains tax. The economy continued to experience record expansion and the
lowest unemployment rates in almost two decades, a combination that in the past
has predictably been accompanied by an increase in inflation. Current

conditions, however, give every indication that inflation is under control.

commitment to helping prudent investors achieve their investment goals. In

products and services designed for the distinct needs of investors who rely on

financial goals by providing quality investment solutions that withstand the
test of time. We thank you for your confidence in Nuveen and our family of
investments, and we look forward to reporting to you again in six months.

Answering Your Questions


Portfolio Manager Rick Huber talks about the municipal bond market and offers
insights into the factors that affected fund performance over the past year.

What key economic and market factors affected the fund's performance over the
past year?

The combination of strong economic growth and low inflation has led to slightly
falling bond yields over the past year. Periodic volatility in the bond market
created a positive environment for the fund, providing a number of opportunities
to purchase attractive bonds at a discount during brief declines in the market.
The market also experienced a significant tightening of credit spreads during
the year, meaning that the difference in the yields of high-quality and low-
quality bonds was gradually reduced to the smallest levels we've seen in many
years. This allowed us to purchase very high quality bonds for the portfolio
without sacrificing much yield.

The Connecticut municipal market experienced very tight supply levels as the
economy continues to feel the effects of the recession of the early 1990s. Also,
state support and tax benefits for municipal bond issuance continue to decline,
resulting in few in-state bonds being issued. Fortunately, we anticipated these
supply problems several years ago, and structured the fund to remain stable
through this market environment.

3
<PAGE>
 
"By maintaining high 
credit quality and being 
structured to withstand 
limited supply, the fund 
continues to perform well 
throughout market cycles."


Given these market conditions, how has the fund performed?

As Tim mentioned in his letter to shareholders, the fund performed well during
the one-year period ended August 31, 1997. The fund outperformed its peer group
average and was ranked favorably by Lipper Analytical Services. In addition to
strong total returns, the fund continued to produce consistent dividends and
generated an annual tax-free yield of 4.53% for Class A shares. Investors in the
34% combined state and federal income tax bracket would have had to earn at
least 6.86% on taxable alternatives to equal that yield on an after-tax basis.
By maintaining high credit quality and being structured to withstand limited
supply, the fund continues to perform well throughout market cycles.

What strategies did you use to add value?

Because of the tight supply of Connecticut bonds, we looked to other areas to
find quality bonds that provided double tax-exemption, rather than sacrificing
credit quality with state bonds that do not meet our credit standards for the
fund. For example, we found several U.S. Territory issues, such as bonds from
Puerto Rico, that proved to be a great addition to the fund. Bonds from U.S.
Territories are exempt from state as well as federal taxes in Connecticut. In
addition, we found value in a number of smaller issues that were largely
overlooked by the retail market.

<PAGE>
 
What is your outlook for the municipal market?

As long as interest rates remain relatively stable, we foresee no major supply
changes in the national municipal bond market. New issuance will likely expand
somewhat as the economy continues to grow. However, if the volatility in the
equity market continues at current levels, we expect demand for bonds to grow as
shareholders move some of their assets from stocks into bonds.

Although the state economy is still recovering from its economic downturn, we
believe that the worst is over and the economy in Connecticut, and all along the
East Coast, will continue to improve. As a result, we anticipate an increased
supply of municipal bonds in the coming months.

What strategies will you employ in the coming year?

We will continue to improve call protection, which will add to the dividend
stability of the fund and reduce its susceptibility to future interest rate
declines. In addition, we will focus on improving the yield of the fund as
credit spreads begin to widen and we are able to seek more value in lower-rated
(but still investment-grade quality) bonds with higher yields. In the meantime,
however, we will strive to take advantage of the opportunities presented by
tight credit spreads to increase the quality of the fund without significantly
sacrificing yield.

1    Class A Share returns are actual. Class B, C and R Share returns are
     actual for the period since class inception; returns prior to Class
     inception are Class A Share returns adjusted (in the case of Class B and
     Class C) for differences in sales charges and expenses, which are
     primarily differences in distribution and service fees. Class A Shares have
     a 4.2% maximum sales charge. Class B Shares have a CDSC that begins at 5%
     for redemptions during the first year after purchase and declines
     periodically to 0% over the following five years, which is not reflected
     in the return figures. Class C Shares have a 1% CDSC for redemptions within
     one year which is not reflected in the one-year total return.

2    Based on SEC yield and a combined federal and state income tax rate of
     34.0%. Represents the yield on a taxable investment necessary to equal the
     yield of the Nuveen fund on an after-tax basis.

                                               August 31, 1997 Semiannual Report

Notes to Financial Statements (Unaudited)

1. General Information and Significant Accounting Policies

The Nuveen Flagship Multistate Trust II (the "Trust") is an open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust comprises Nuveen Flagship Connecticut Municipal Bond Fund (the "Fund"),
among others. The Trust was organized as a Massachusetts business trust on July
1, 1996.

The John Nuveen Company, parent of John Nuveen & Co. Incorporated ("Nuveen") and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Fund, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December 1996.

After the close of business on January 31, 1997, Flagship Connecticut Double Tax
Exempt Fund ("Flagship Connecticut") was reorganized into the Trust and renamed
Nuveen Flagship Connecticut Municipal Bond Fund. Flagship Connecticut had a May
31 fiscal year end prior to being reorganized into the Trust and now has a
February 28 fiscal year end.

The Fund seeks to provide high tax-free income and preservation of capital
through investments in a diversified portfolio of quality municipal bonds.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements in accordance with generally
accepted accounting principles.

Securities Valuation

The prices of municipal bonds in the Fund's investment portfolio are provided by
a pricing service approved by the Fund's Board of Trustees. When price quotes
are not readily available (which is usually the case for municipal securities),
the pricing service establishes fair market value based on yields or prices of
municipal bonds of comparable quality, type of issue, coupon, maturity and
rating, indications of value from securities dealers and general market
conditions. Temporary investments in securities that have variable rate and
demand features qualifying them as short-term securities are valued at amortized
cost, which approximates market value.

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of its when-issued and delayed delivery purchase commitments. At
August 31, 1997, there were no such purchase commitments.

Notes to Financial Statements (Unaudited) -- continued

Interest Income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and Distributions to Shareholders

Tax-exempt net investment income is declared as a dividend monthly and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryovers.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Income Taxes

The Fund is a separate taxpayer for federal income tax purposes. The Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Fund
currently considers significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, the Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal and Connecticut state income taxes, to
retain such tax-exempt status when distributed to the shareholders of the Fund.
Net realized capital gain and market discount distributions are subject to
federal taxation.

Flexible Sales Charge Program

The Fund offers Class A, B, C and R Shares. Class A Shares are sold with a sales
charge and incur an annual 12b-1 service fee. Class A Share purchases of $1
million or more are sold at net asset value without an up-front sales charge but
may be subject to a 1% contingent deferred sales charge ("CDSC") if redeemed
within 18 months of purchase. Class B Shares are sold without a sales charge but
incur annual 12b-1 distribution and service fees. An investor purchasing Class B
Shares agrees to pay a CDSC of up to 5% depending upon the length of time the
shares are held by the investor (CDSC is reduced to 0% at the end of six years).
Class B Shares convert to Class A Shares eight years after purchase. Class C
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1%
if Class C Shares are redeemed within one year of purchase. Class R Shares are
not subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available for purchases of over $1 million and in other limited
circumstances.

                                               August 31, 1997 Semiannual Report

Derivative Financial Instruments

The Fund may invest in certain derivative financial instruments including
futures, forward, swap, option contracts and other financial instruments with
similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the six months ended August 31, 1997.

Expense Allocation

Expenses of the Fund that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period.

Dear Shareholder

[PHOTO OF TIMOTHY R. SCHWERTFEGER APPEARS HERE]

Wealth takes a lifetime 
to build. Once achieved, 
it should be preserved.

It is a pleasure to report to you on the performance of the Nuveen New Jersey
Municipal Bond Funds. Both funds performed well over the past six months,
rewarding investors with attractive tax-free income, consistent performance and
capital preservation.

For the 12 months ended August 31, 1997, the long-term New Jersey fund provided
Class A shareholders with a total return on net asset value of 8.41%, outpacing
the average return of 8.18% for its peer group, the Lipper New Jersey Municipal
Bond Fund Category. The intermediate-term New Jersey fund also performed well
over the period, providing Class A shareholders with a total return of 6.89%,
outperforming its Lipper peer group average of 6.70% (the Lipper Other States
Intermediate Municipal Bond Fund Category).

This strong performance was achieved in an environment of periodic interest rate
volatility. Positive news on the inflation front helped soften the effects of a
hike in short-term interest rates by the Federal Reserve Board in late March.
After tightening short-term interest rates by 0.25%, the Federal Reserve
demonstrated its confidence in the economy's path by maintaining the status quo
at subsequent meetings.

"Both funds performed well over the past six months, rewarding investors with
attractive tax-free income, consistent performance and capital preservation."

So far in 1997, investors have focused their attention on fiscal issues such as
the federal budget accord and tax cut measures, including a reduction in the
capital gains tax. The economy continued to experience record expansion and the
lowest unemployment rates in almost two decades, a combination that in the past
has predictably been accompanied by an increase in inflation. Current
conditions, however, give every indication that inflation is under control.

Nuveen's financial products and services continue to evolve as we extend our
commitment to helping prudent investors achieve their investment goals. In
addition to our 35 municipal mutual funds, Nuveen now offers a variety of other
products and services designed for the distinct needs of investors who rely on
their investment portfolios as their principal source of income and financial
security. We recently celebrated the successful first year of our high-
performing Nuveen Growth and Income Stock Fund, as well as two new balanced
stock and bond funds. We have also expanded our private asset management service
by acquiring Rittenhouse Financial Services, a well-respected provider of growth
investment management services.

Nuveen prides itself on helping more than 1.3 million investors achieve their
financial goals by providing quality investment solutions that withstand the
test of time. We thank you for your confidence in Nuveen and our family of
investments, and we look forward to reporting to you again in six months.

Sincerely,

Answering Your Questions



Portfolio Managers Rick Huber and Steve Peterson talk about the municipal bond
market and offer insights into the factors that affected fund performance over
the past year.


What key economic and market factors affected the funds' performance over the
past year?

The combination of strong economic growth and low inflation has led to slightly
falling bond yields over the past year. Periodic volatility in the bond market
created a positive environment for the funds, providing us with a number of
opportunities to purchase attractive bonds at discounts during brief declines in
the market. The market also experienced a significant tightening of credit
spreads during the year, meaning that the difference in the yields of high-
quality and low-quality bonds was gradually reduced to the smallest levels we've
seen in many years. This allowed us to purchase very high quality bonds for the
portfolios without sacrificing much yield.

Given these market conditions, how
have the funds performed?

As Tim mentioned in his letter to shareholders, the funds performed well during
the one-year period ended August 31, 1997. Both funds generated excellent total
returns and were ranked favorably among their respective peer groups. The long-
term New Jersey fund's Class R shares also received a five-star rating from
Morningstar, which rates mutual funds on a risk-adjusted basis. In addition to
strong total returns, the funds continued to produce consistent dividends.
Annual tax-free yields as of August 31, 1997, for Class A shares of the long-
term New Jersey fund were 5.07%, and for the intermediate New Jersey

fund, were 3.87%. Investors in the 35.5% combined state and federal income tax
bracket would have had to earn at least 7.86% and 6.00%, respectively, on
taxable alternatives to equal these yields on an after-tax basis.

What strategies did you use to add value?

As credit spreads tightened during the year, we focused on taking advantage of
the opportunities to purchase bonds with higher credit quality at yields that
were close to bonds with lower credit ratings. We believe that as credit spreads
widen again, these high-quality issues will appreciate in value relative to
lower-grade bonds. We also focused on extending the call protection of the
funds, which should help increase their dividend stability.

What is your outlook for the municipal market?

As long as interest rates remain relatively stable, we foresee no major supply
changes in the national municipal bond market. New issuance will likely expand
somewhat as the economy continues to grow. However, if the volatility in the
equity market continues at current levels, we expect demand for bonds to grow as
shareholders move some of their assets from stocks into bonds. The New Jersey
municipal bond market should experience stronger supply growth as the economy
continues to recover from

<PAGE>
 
the national and state recessions experienced in the early 1990s. Demand for
municipal bonds should remain strong, given the relatively high state tax rates
and high level of per capita wealth in the state.

What strategies will you employ in the coming year?

We will continue to focus on maintaining the dividend stability of the funds,
while seeking to maximize after-tax total return. We will strive to increase the
call protection of the bonds in the portfolios as long as this remains a low-
cost option. For the long-term New Jersey fund, we plan to take advantage of any
widening of credit spreads to increase the overall yield of the fund. For the
intermediate-term New Jersey fund, we will focus on reducing its maturity and
duration, which will lower the volatility of the fund.

/1/  Overall rating for Class R Shares based on risk-adjusted performance for
     the period ending August 31, 1997, by Morningstar Inc., an independent
     mutual fund rating service. The fund was compared with 1,354 municipal bond
     funds for the three-year period, 654 funds for the five-year period and
     316 funds for the 10-year period. The top 10% of funds in the category
     receive five stars, and the next 22.5% of funds receive four stars.

/2/  Class R Share returns are actual. Class A, B and C Share returns are actual
     for the period since class inception; returns prior to class inception are
     Class R Share returns adjusted for differences in sales charges and
     expenses, which are primarily differences in distribution and service
     fees. Class A Shares have a 4.2% maximum sales charge. Class B Shares have
     a CDSC that begins at 5% for redemptions during the first year after
     purchase and declines periodically to 0% over the following five years,
     which is not reflected in the return figures. Class C Shares have a 1% CDSC
     for redemptions within one year which is not reflected in the one-year
     total return.

/3/  Based on SEC yield and a combined federal and state income tax rate of
     35.5%. Represents the yield on a taxable investment necessary to equal the
     yield of the Nuveen fund on an after-tax basis.

Nuveen Municipal Bond Funds
August 31, 1997 Semiannual Report


1. General Information and Significant Accounting Policies
The Nuveen Flagship Multistate Trust II (the "Trust") is an open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust comprises the Nuveen Flagship New Jersey Municipal Bond Fund ("Nuveen
Flagship New Jersey") and the Nuveen Flagship New Jersey Intermediate Municipal
Bond Fund ("Nuveen Flagship New Jersey Intermediate") (collectively the
"Funds"), among others. The Trust was organized as a Massachusetts business
trust on July 1, 1996.

The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Funds, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December, 1996. 

After the close of business on January 31, 1997, Nuveen New Jersey Tax-Free
Value Fund ("Nuveen New Jersey") and Flagship New Jersey Double Tax Exempt Fund
("Flagship New Jersey") reorganized into Nuveen Flagship New Jersey. Flagship's
New Jersey Intermediate Tax Exempt Fund ("Flagship New Jersey Intermediate") was
reorganized into the Trust and renamed Nuveen Flagship New Jersey Intermediate
Municipal Bond Fund. Prior to these reorganizations, Nuveen New Jersey was a
series of the Nuveen Multistate Tax-Free Trust while Flagship New Jersey and
Flagship New Jersey Intermediate were each a sub-trust of the Flagship Tax
Exempt Funds Trust. Nuveen New Jersey had a January 31 fiscal year end and
Flagship New Jersey had a May 31 fiscal year end prior to being reorganized into
Nuveen Flagship New Jersey which has a February 28 fiscal year end. Flagship New
Jersey Intermediate had a May 31 fiscal year end prior to being reorganized into
the Trust and now has a February 28 fiscal year end. 

Each Fund seeks to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
generally accepted accounting principles.

Securities Valuation
The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Trustees. When price quotes
are not readily available (which is usually the case for municipal securities),
the pricing service establishes fair market value based on yields or prices of
municipal bonds of comparable quality, type of issue, coupon, maturity and
rating, indications of value from securities dealers and general market
conditions. Temporary investments in securities that have variable rate and
demand features qualifying them as short-term securities are valued at amortized
cost, which approximates market value.

Securities Transactions
Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of their when-issued and delayed delivery purchase commitments. At
August 31, 1997, Nuveen Flagship New Jersey had such outstanding purchase
commitments of $932,606. Nuveen Flagship New Jersey Intermediate had no such
outstanding purchase commitments.

Investment Income
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt
securities when required for federal income tax purposes.

Dividends and Distributions to Shareholders
Tax-exempt net investment income is declared as a dividend monthly and payment
is made or reinvestment is credited to shareholders accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to
the extent they exceed available capital loss carryovers.  

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Income Taxes
Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Funds
currently consider significant net realized capital gains and/or market discount
as amounts in excess of $.001 per share. Furthermore, each Fund intends to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal and New Jersey state income taxes, to retain such
tax-exempt status when distributed to the shareholders of the Funds. Net
realized capital gain and market discount distributions are subject to federal
taxation.

Nuveen Municipal Bond Funds
August 31, 1997 Semiannual Report

Flexible Sales Charge Program
Each Fund offers Class A, C and R Shares. Nuveen Flagship New Jersey also offers
Class B Shares. Class A Shares are sold with a sales charge and incur an annual
12b-1 service fee. Class A Share purchases of $1 million or more are sold at net
asset value without an up-front sales charge but may be subject to a 1%
contingent deferred sales charge ("CDSC") if redeemed within 18 months of
purchase. Class B Shares are sold without a sales charge but incur annual 12b-1
distribution and service fees. An investor purchasing Class B Shares agrees to
pay a CDSC of up to 5% depending upon the length of time the shares are held by
the investor (CDSC is reduced to 0% at the end of six years). Class B Shares
convert to Class A Shares eight years after purchase. Class C Shares are sold
without a sales charge but incur annual 12b-1 distribution and service fees. An
investor purchasing Class C Shares agrees to pay a CDSC of 1% if Class C Shares
are redeemed within one year of purchase. Class R Shares are not subject to any
sales charge or 12b-1 distribution or service fees. Class R Shares are available
for purchases of over $1 million and in other limited circumstances.

Derivative Financial Instruments
The Funds may invest in certain derivative financial instruments including
futures, forward, swap, option contracts, and other financial instruments with
similar characteristics. Although the Funds are authorized to invest in such
financial instruments, and may do so in the future, they did not make any such
investments during the six months ended August 31, 1997.

Expense Allocation
Expenses of the Funds that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Use of Estimates
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period.

Organizational Expenses
The organizational expenses incurred on behalf of Nuveen Flagship New Jersey
Intermediate (approximately $32,200) will be reimbursed to the Adviser on a
straight-line basis over a period of three years beginning June 1, 1996. As of
August 31, 1997, $12,510 has been reimbursed. In the event that the Adviser's
current investment in the Trust falls below $100,000 prior to the full
reimbursement of the organizational expenses, then it will forego any further
reimbursement.

Dear Shareholder

Chairman of the Board

Wealth takes a lifetime to build. Once achieved, it should be preserved.



It is a pleasure to report to you on the performance of the Nuveen New York
Municipal Bond Funds. Both funds performed well over the past six months,
rewarding investors with attractive tax-free income, consistent performance and
capital preservation.

For the 12 months ended August 31, 1997, the uninsured New York fund provided
Class A shareholders with a total return on net asset value of 9.68%,
surpassing the 9.25% return generated by the unmanaged Lehman Brothers Municipal
Bond Index. The fund also outpaced the average return of 8.93% for its peer
group, the Lipper New York Municipal Bond Fund Category. The insured New York
fund also performed well, providing Class A shareholders with an annual total
return of 7.56%, which compares with its peer group average of 7.72% for the
Lipper New York Insured Municipal Bond Fund Category.

This strong performance was achieved in an environment of periodic interest rate
volatility. Positive news on the inflation front helped soften the effects of a
hike in short-term interest rates by the Federal Reserve Board in late March.
After tightening short-term interest rates by 0.25%, the Federal Reserve
demonstrated its confidence in the economy's path by maintaining the status quo
at subsequent meetings.

"Both funds performed well over the past six months, rewarding investors with
attractive tax-free income, consistent performance and capital preservation."

So far in 1997, investors have focused their attention on fiscal issues such as
the federal budget accord and tax cut measures, including a reduction in the
capital gains tax. The economy continued to experience record expansion and the
lowest unemployment rates in almost two decades, a combination that in the past
has predictably been accompanied by an increase in inflation. Current
conditions, however, give every indication that inflation is under control.

Nuveen's financial products and services continue to evolve as we extend our
commitment to helping prudent investors achieve their investment goals. In
addition to our 35 municipal mutual funds, Nuveen now offers a variety of other
products and services designed for the distinct needs of investors who rely on
their investment portfolios as their principal source of income and financial
security. We recently celebrated the successful first year of our high-
performing Nuveen Growth and Income Stock Fund, as well as two new balanced
stock and bond funds. We have also expanded our private asset management
service by acquiring Rittenhouse Financial Services, a well-respected provider
of growth investment management services.

Nuveen prides itself on helping more than 1.3 million investors achieve their
financial goals by providing quality investment solutions that withstand the
test of time. We thank you for your confidence in Nuveen and our family of
investments, and we look forward to reporting to you again in six months.

Sincerely,

Answering Your Questions


Portfolio Manager Dan Solender talks about the municipal bond market and offers
insights into the factors that affected fund performance over the past year.

What key economic and market factors affected the funds' performance over the
past year?

The combination of strong economic growth and low inflation has led to slightly
falling bond yields over the past year. Periodic volatility in the bond market
created a positive environment for the funds, providing us with a number of
opportunities to purchase attractive bonds at discounts during brief declines
in the market. The market also experienced a significant tightening of credit
spreads during the year, meaning that the difference in the yields of high-
quality and low-quality bonds was gradually reduced to the smallest levels
we've seen in many years. This allowed us to purchase very high quality bonds
for the portfolios without sacrificing much yield.

The supply of new bond issuance increased a modest seven percent nationally,
while municipal supply in New York increased 23 percent. The impact of this
dramatic increase in supply was softened by the improving economy in New York
City and New York state, as both ended their fiscal years with budget surpluses
due to higher-than-expected tax revenues from the financial services industry.

Given these market conditions, how have the funds performed?

As Tim mentioned in his letter to shareholders, both funds performed well during
the one-year period ended August 31, 1997. The uninsured New York fund's Class A
shares were rated among the top 25 percent of New York

market in the coming months."


municipal bond funds by Lipper Analytical Services. The fund's Class R shares
also received a five-star rating from Morningstar, which rates mutual funds on a
risk-adjusted basis.


In addition to strong total returns, the funds continued to produce consistent
dividends and annual tax-free yields. Class A shareholders received 4.54% for
the uninsured New York fund and 3.97% for the insured New York fund. Investors
in the 35.5% combined state and federal income tax bracket would have had to
earn at least 7.04% and 6.16%, respectively, on taxable alternatives to equal
these yields on an after-tax basis.

What strategies did you use to add value?

Earlier in the year, we found good values in bonds supported by appropriations
from the New York state government that offered excellent yields relative to
higher-rated bonds. We took advantage of the high yields on these investment-
grade quality bonds, which our research indicated would be a good addition to
the funds.

As credit spreads tightened during the year, we focused on taking advantage of
opportunities to purchase bonds with higher credit quality at yields that were
similar to bonds that were rated much lower. We believe that as credit spreads
widen again, these high-quality issues will appreciate in value relative to
lower-grade bonds. Since credit quality does not really affect the insured fund
(in which 99% of the bonds are AAA-rated), we focused on extending the call
protection of the fund, which should increase its dividend stability.

<PAGE>
 
What is your outlook for the municipal market?

As long as interest rates remain relatively stable, we foresee no major supply
changes in the national municipal bond market. New issuance will likely expand
somewhat as the economy continues to grow. However, if the volatility in the
equity market continues at current levels, we expect demand for bonds to grow
as shareholders move some of their assets from stocks into bonds.

New York promises to be one of the most exciting areas of the municipal bond
market in the coming months. In early October, New York City is expected to
bring bonds to market through its new venue, the Transitional Finance Authority.
An even larger potential new issuer would be the Long Island Power Authority,
which could bring to market the largest municipal bond issuance ever, if its
transaction with the Long Island Lighting Company is approved. In addition, we
are still keeping a watchful eye on the utility sector as the results of
deregulation begin to take shape.

What strategies will you employ in the coming year?

We plan to take advantage of supply and demand imbalances as new issues come to
market, as well as to find bonds trading in the secondary market that may be
overlooked as attention focuses on new issues. In addition, we will strive to
increase the call protection of the bonds in the portfolios as long as this
remains a low-cost option. For the uninsured fund, we will try also to take
advantage of any widening of credit spreads to increase the overall yield of the
fund.

Notes to Financial Statements (Unaudited)          Nuveen Municipal Bond Funds
                                             August 31, 1997 Semiannual Report

1. General Information and Significant Accounting Policies 
The Nuveen Flagship Multistate Trust II (the "Trust") is an open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust comprises the Nuveen Flagship New York Municipal Bond Fund ("Nuveen
Flagship New York") and the Nuveen New York Insured Municipal Bond Fund ("Nuveen
New York Insured") (collectively, the "Funds"), among others. The Trust was
organized as a Massachusetts business trust on July 1, 1996.

The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co. Incorporated,
and Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Funds, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December 1996.

After the close of business on January 31, 1997, Nuveen New York Tax-Free Value
Fund ("Nuveen New York") and Flagship New York Tax-Exempt Fund ("Flagship New
York") reorganized into Nuveen Flagship New York. Nuveen New York Insured Tax-
Free Value Fund was reorganized into the Trust and renamed Nuveen New York
Insured Municipal Bond Fund. Prior to these reorganizations, Nuveen New York was
a series of the Nuveen Tax-Free Bond Fund, Inc., Flagship New York was a sub-
trust of Flagship Tax Exempt Funds Trust, and Nuveen New York Insured Tax-Free
Value Fund was a series of Nuveen Insured Tax-Free Bond Fund, Inc., each an 
open-end management investment company.

Each Fund seeks to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
generally accepted accounting principles.

Securities Valuation 
The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved and supervised by the Fund's Board of Trustees.
When price quotes are not readily available (which is usually the case for
municipal securities), the pricing service establishes fair market value based
on yields or prices of municipal bonds of comparable quality, type of issue,
coupon, maturity and rating, indications of value from securities dealers and
general market conditions. Temporary investments in securities that have
variable rate and demand features qualifying them as short-term securities are
valued at amortized cost, which approximates market value.

Securities Transactions 
Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of their when-issued and delayed delivery purchase commitments. At
August 31, 1997, the Funds had no such outstanding purchase commitments.

Note to Financial statements (Unaudited) -- Continued
 
Interest Income 
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and Distributions to Shareholders 
Tax-exempt net investment income is declared as a dividend monthly and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryovers.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Income Taxes 
Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Funds
currently consider significant net realized capital gains and/or market discount
as amounts in excess of $.001 per share. Furthermore, each Fund intends to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal and New York state income taxes, to retain such
tax-exempt status when distributed to the shareholders of the Funds. Net
realized capital gain and market discount distributions are subject to federal
taxation.

Insurance 
Nuveen New York Insured invests in municipal securities which are either covered
by insurance or backed by an escrow or trust account containing sufficient U.S.
Government or U.S. Government agency securities, both of which ensure the timely
payment of principal and interest. Each insured municipal security is covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
Such insurance does not guarantee the market value of the municipal securities
or the value of the Fund's shares. Original Issue Insurance and Secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Fund ultimately disposes of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue Insurance or
Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only while the municipal securities are held by
the Fund. Accordingly, neither the prices used in determining the market value

of the Portfolio Insurance does, however, give the Fund the right to obtain
permanent insurance with respect to the municipal security covered by the
Portfolio Insurance policy at the time of its sale.

Flexible Sales Charge Program 
Each Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
but may be subject to a 1% contingent deferred sales charge ("CDSC") if redeemed
within 18 months of purchase. Class B Shares are sold without a sales charge but
incur annual 12b-1 distribution and service fees. An investor purchasing Class B
Shares agrees to pay a CDSC of up to 5% depending upon the length of time the
shares are held by the investor (CDSC is reduced to 0% at the end of six years).
Class B Shares convert to Class A Shares eight years after purchase. Class C
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1%
if Class C Shares are redeemed within one year of purchase. Class R Shares are
not subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available for purchases of over $1 million and in other limited
circumstances.

Derivative Financial Instruments
The Funds may invest in certain derivative financial instruments including
futures, forward, swap, option contracts, and other financial instruments with
similar characteristics. Although the Funds are authorized to invest in such
financial instruments, and may do so in the future, they did not make any such
investments during the six months year ended August 31, 1997. 

Expense Allocation
Expenses of the Funds that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Use of Estimates 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period.

6. Management Fee and Other Transactions with Affiliates
Under the Trusts' investment management agreement with the Adviser, each Fund
pays an annual management fee, payable monthly, at the rates set forth below
which are based upon the average daily net asset value of each Fund:

Average daily net asset value                                     Management fee
- --------------------------------------------------------------------------------
For the first $125 million                                           .5500 of 1%
For the next $125 million                                            .5375 of 1
For the next $250 million                                            .5250 of 1
For the next $500 million                                            .5125 of 1
For the next $1 billion                                              .5000 of 1
For net assets over $2 billion                                       .4750 of 1
- --------------------------------------------------------------------------------

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Trust pays no
compensation directly to its Trustees who are affiliated with the Adviser or to
its officers, all of whom receive remuneration for their services to the Trust
from the Adviser.

The Adviser has agreed to waive part of its management fees or reimburse certain
expenses of each Fund in order to limit total expenses to .75 of 1% of the
average daily net asset value of Nuveen Flagship New York and .975 of 1% of the
average daily net asset value of Nuveen New York Insured, excluding any 12b-1
fees applicable to Class A, B and C Shares. The Adviser may voluntarily
reimburse additional expenses from time to time, which may be terminated at any
time at its discretion.

During the six months ended August 31, 1997, the Distributor collected sales
charges on purchases of Class A Shares of approximately $117,100 and $139,200
for Nuveen Flagship New York and Nuveen New York Insured, respectively, of which
approximately $94,700 and $108,100, respectively, were paid out as concessions
to authorized dealers. The Distributor also received 12b-1 service fees on
Class A Shares, substantially all of which were paid to compensate authorized
dealers for providing services to shareholders relating to their investments.

During the six months ended August 31, 1997, the Distributor compensated
authorized dealers directly with approximately $63,800 and $52,100 in
commission advances at the time of purchase for Nuveen Flagship New York and
Nuveen New York Insured, respectively. To compensate for commissions advanced
to authorized dealers, all 12b-1 service fees collected on Class B Shares during
the first year following a purchase, all 12b-1 distribution fees on Class B
Shares, and all 12b-1 service and distribution fees on Class C Shares during the
first year following a purchase are retained by the Distributor. During the six
months ended August 31, 1997, the Distributor retained approximately $16,900 and
$12,800 in such 12b-1 fees for Nuveen Flagship New York and Nuveen New York
Insured, respectively. The remaining 12b-1 fees charged to the Funds were paid
to compensate authorized dealers for providing services to shareholders relating
to their investments. The Distributor also collected and retained approximately
$2,600 and $2,900 of CDSC on share redemptions for Nuveen Flagship New York and
Nuveen New York Insured, respectively, during the six months ended August 31,
1997.

Dear Shareholder

Chairman of the Board


Wealth takes a lifetime 
to build. Once achieved, 
it should be preserved.


It is a pleasure to report to you on the performance of the Nuveen Massachusetts
Municipal Bond Funds. Both funds performed well over the past six months,
rewarding investors with attractive tax-free income, consistent performance and
capital preservation.

For the 12 months ended August 31, 1997, the uninsured Massachusetts fund
provided Class A shareholders with a total return on net asset value of 7.04%.
Class A shareholders in the insured Massachusetts fund received an annual total
return of 6.77%. Both funds continued to provide consistent income, and each
fund experienced a slight increase in its monthly dividend last February.

This performance was achieved in an environment of periodic interest rate
volatility. Positive news on the inflation front helped soften the effects of a
hike in short-term interest rates by the Federal Reserve Board in late March.
After tightening short-term interest rates by 0.25%, the Federal Reserve
demonstrated its confidence in the economy's path by maintaining the status quo
at subsequent meetings.

So far in 1997, investors have focused their attention on fiscal issues such as
the federal budget accord and tax cut measures, including a reduction in the
capital gains tax. The economy continued to experience record expansion and the
lowest unemployment rates in almost two decades, a combination that in the past
has predictably been accompanied by an increase in inflation. Current
conditions, however, give every indication that inflation is under control.

Answering Your Questions



Portfolio Manager Steve Peterson talks about the municipal bond market and
offers insights into the factors that affected fund performance over the past
year.


What key economic and market factors affected the funds' performance over the
past year?

The combination of strong economic growth and low inflation has led to slightly
falling bond yields over the past year. Periodic volatility in the bond market
created a positive environment for the funds, providing a number of
opportunities to purchase attractive bonds at discounts during brief declines in
the market. The market also experienced a significant tightening of credit
spreads during the year, meaning that the difference in the yields of high-
quality and low-quality bonds was gradually reduced to the smallest levels we've
seen in many years. This allowed us to purchase very high quality bonds for the
portfolios without sacrificing much yield. The supply of new bond issuance
remained low, increasing a modest seven percent nationwide.

Given these market conditions, how have the funds performed?

The funds turned in relatively solid total return performance for the period
ended August 31, 1997, but fell below peer averages due to the funds' shorter
duration. Duration is a measure of a bond fund's interest rate sensitivity; the
shorter the duration, the less a fund's value fluctuates for a given change in
interest rates. Shorter duration bonds experience subdued performance in
declining interest rate environments and enhanced performance in rising rate
environments.

"The funds continued to produce stable dividends and attractive tax-free
yields."


During this volatile period in the bond market, the funds continued to produce
stable dividends and attractive tax-free yields. In addition, they performed
very well on a risk-adjusted basis, as is evidenced by both funds' four-star
rating by Morningstar (for Class R shares), which rates mutual funds on a risk-
adjusted basis.

What strategies did you use to add value?
As credit spreads tightened during the year, we focused on taking advantage of
the opportunities to purchase bonds with higher credit quality at yields that
were similar to bonds with lower credit ratings. We believe that as credit
spreads widen again, these high-quality issues will appreciate in value relative
to lower-grade bonds. In addition, our diligent research helped us find
undervalued bonds in the housing and education sectors that proved to be
excellent values for the funds.

We also took advantage of the volatile interest rate environment to buy and sell
bonds with embedded calls. The call feature of a bond, which allows an issuer to
retire a bond at par, or a slight premium, will change in value based on
interest rate levels and changes in the market. As opportunities arose, we
purchased bonds with calls we felt were mispriced and waited for the market to
recognize their value - resulting in price appreciation for the funds.

<PAGE>
 
What is your outlook for the municipal market?
As long as interest rates remain relatively stable, we foresee no major supply
changes in the national municipal bond market. New issuance will likely expand
somewhat as the economy continues to grow. However, if the volatility in the
equity market continues at current levels, we expect demand for bonds to grow as
shareholders move some of their assets from stocks into bonds. In addition, we
expect a number of good opportunities to arise as credit spreads widen and a
larger number of higher-yielding bonds come to market.

The Massachusetts municipal bond market should experience somewhat stronger
supply growth as the economy continues to recover from the national and state
recessions experienced in the early 1990s. Demand for municipal bonds should
remain strong, given the relatively high state tax rates and increasing levels
of per capita wealth in the state.

What strategies will you employ in the coming year?
We will continue to focus on maximizing after-tax total return, working to
minimize the potentially adverse effect of realized capital gains on investors'
tax liabilities and trying to offset capital gains with realized capital losses.
We will also try to take advantage of any widening of credit spreads to increase
the overall yield of the uninsured fund as more investment-grade quality bonds
with higher yields become available.

1 Overall rating for Class R Shares based on risk-adjusted performance for the
  period ending August 31, 1997, by Morningstar Inc., an independent mutual fund
  rating service. The fund was compared with 1,354 municipal bond funds for the
  three-year period, 654 funds for the five-year period and 316 funds for the 
  10-year period. The top 10% of funds in the category receive five stars, and

2 Class R Share returns are actual. Class A, B and C Share returns are actual
  for the period since class inception; returns prior to class inception are
  Class R Share returns adjusted for differences in sales charges and expenses,
  which are primarily differences in distribution and service fees. Class A
  Shares have a 4.2% maximum sales charge. Class B Shares have a CDSC that
  begins at 5% for redemptions during the first year after purchase and declines
  periodically to 0% over the following five years, which is not reflected in
  the return figures. Class C Shares have a 1% CDSC for redemptions within one
  year which is not reflected in the one-year total return.

Notes to Financial Statements (Unaudited)           Nuveen Municipal Bond Funds
                                              August 31, 1997 Semiannual Report


1. General Information and Significant Accounting Policies

Nuveen Flagship Multistate Trust II (the "Trust") is an open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust comprises the Nuveen Massachusetts Municipal Bond Fund ("Massachusetts")
and the Nuveen Massachusetts Insured Municipal Bond Fund ("Massachusetts
Insured") (collectively, the "Funds"), among others. The Trust was organized as
a Massachusetts business trust on July 1, 1996.

The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Funds, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business
on January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December, 1996.

After the close of business on January 31, 1997, Massachusetts and Massachusetts
Insured were renamed and reorganized into the Trust. Prior to the
reorganization, Massachusetts (formerly Nuveen Massachusetts Tax-Free Value
Fund) was a series of the Nuveen Tax-Free Bond Fund, Inc., and Massachusetts
Insured (formerly Nuveen Massachusetts Insured Tax-Free Value Fund) was a series
of the Nuveen Insured Tax-Free Bond Fund, Inc., each an open-end diversified
management investment company.

Each Fund seeks to provide high tax-free income and preservation of capital
through investments in diversified portfolios of quality municipal bonds.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
generally accepted accounting principles.

Securities Valuation

The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Trustees. When price
quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.

Securities Transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject
to market fluctuation during this period. The Funds have instructed the
custodian to segregate assets in a separate account with a current value at
least equal to the amount of their when-issued and delayed delivery purchase
commitments. At August 31, 1997, there were no such purchase commitments in
either Fund.

Notes to Financial Statements (Unaudited) -- continued
 
Investment Income 

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt
securities when required for federal income tax purposes.

Dividends and Distributions to Shareholders 

Tax-exempt net investment income is declared as a dividend monthly and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and /or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to
the extent they exceed available capital loss carryovers. 

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Funds
currently consider significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, each Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal and Massachusetts state income taxes, to
retain such tax-exempt status when distributed to the shareholders of the
Funds. Net realized capital gain and market discount distributions are subject
to federal taxation.

Insurance

Massachusetts Insured invests in municipal securities which are either covered
by insurance or backed by an escrow or trust account containing sufficient U.S.
Government or U.S. Government agency securities, both of which ensure the timely
payment of principal and interest. Each insured municipal security is covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
Such insurance does not guarantee the market value of the municipal securities
or the value of the Fund's shares. Original Issue Insurance and Secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Fund ultimately disposes of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue Insurance or
Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only while the municipal securities are held by
the Fund. Accordingly, neither the prices used in determining the market value
of the underlying municipal securities nor the net asset value of the Fund's
shares include value, if any, attributable to the Portfolio Insurance. Each

of the Portfolio Insurance does, however, give the Fund the right to obtain
permanent insurance with respect to the municipal security covered by the
Portfolio Insurance policy at the time of its sale.

Flexible Sales Charge Program

Each Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
but may be subject to a 1% contingent deferred sales charge ("CDSC") if
redeemed within 18 months of purchase. Class B Shares are sold without a sales
charge but incur annual 12b-1 distribution and service fees. An investor
purchasing Class B Shares agrees to pay a CDSC of up to 5% depending upon the
length of time the shares are held by the investor (CDSC is reduced to 0% at the
end of six years). Class B Shares convert to Class A Shares eight years after
purchase. Class C Shares are sold without a sales charge but incur annual 12b-1
distribution and service fees. An investor purchasing Class C Shares agrees to
pay a CDSC of 1% if Class C Shares are redeemed within one year of purchase.
Class R Shares are not subject to any sales charge or 12b-1 distribution or
service fees. Class R Shares are available for purchases of over $1 million and
in other limited circumstances.

Derivative Financial Instruments

The Funds may invest in certain derivative financial instruments including
futures, forward, swap, option contracts, and other financial instruments with
similar characteristics. Although the Funds are authorized to invest in such
financial instruments, and may do so in the future, they did not make any such
investments during the six months ended August 31, 1997.

Expense Allocation

Expenses of the Funds that are not directly attributable to a specific class of
shares are prorated among the classes based on the relative net assets of each
class. Expenses directly attributable to a class of shares, which presently only
includes 12b-1 distribution and service fees, are recorded to the specific
class.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period.

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Trust pays no
compensation directly to its Trustees who are affiliated with the Adviser or to
its officers, all of whom receive remuneration for their services to the Trust
from the Adviser.

The Adviser has agreed to waive part of its management fees or reimburse certain
expenses of each Fund in order to limit total expenses to .75 of 1% of the
average daily net asset value of Massachusetts and .975 of 1% of the average
daily net asset value of Massachusetts Insured, excluding any 12b-1 fees
applicable to Class A, B and C Shares. The Adviser may voluntarily reimburse
additional expenses from time to time, which may be terminated at any time at
its discretion.

During the six months ended August 31, 1997, the Distributor collected sales
charges on purchases of Class A Shares of approximately $30,600 and $14,700 for
Massachusetts and Massachusetts Insured, respectively, of which approximately
$26,600 and $12,800, respectively, were paid out as concessions to authorized
dealers. The Distributor also received 12b-1 service fees on Class A Shares,
substantially all of which were paid to compensate authorized dealers for
providing services to shareholders relating to their investments.

During the six months ended August 31, 1997, the Distributor compensated
authorized dealers directly with approximately $16,000 and $4,900 in commission
advances at the time of purchase for Massachusetts and Massachusetts Insured,
respectively. To compensate for commissions advanced to authorized dealers, all
12b-1 service fees collected on Class B Shares during the first year following
a purchase, all 12b-1 distribution fees on Class B Shares, and all 12b-1 service
and distribution fees on Class C Shares during the first year following a
purchase are retained by the Distributor. During the six months ended August 31,
1997, the Distributor retained approximately $1,800 and $800 in such 12b-1 fees
for Massachusetts and Massachusetts Insured, respectively. The remaining 12b-1
fees charged to the Funds were paid to compensate authorized dealers for
providing services to shareholders relating to their investments. The
Distributor also collected and retained approximately $7,600 of CDSC on
Massachusetts share redemptions during the six months ended August 31, 1997.
