Is it Time for a Financial Check-Up?

Now is a great time to sit down with your financial adviser and review your
financial plan. How can you make sure that your investment strategy is strong
enough to provide the income you need today and versatile enough to change as
your goals do? Here are some guidelines:

 .  Make sure you and your adviser understand your current situation. How have
   your goals, objectives and risk profile changed? What are your current tax
   concerns, interests, lifestyle?

 .  Revisit your current investment choices. If the value of one portion of your
   portfolio has grown substantially, it may be time me to rebalance asset
   classes.

 .  Determine how your asset mix will be implemented. Changing your asset
   allocation is generally a gradual process. Make sure you and your adviser
   have a clear understanding of each other's responsibilities. Define and
   discuss what you want in terms of support from your adviser.

 .  Keep revisiting your plan. Don't assume that once you've revised your plan
   and reallocated your portfolio the process is finished.

It's recommended that you meet at least once a year with your financial 
adviser -- and usually more if there have been significant changes in interest 
rates, tax laws, retirement plan distributions, lifestyle or health. Even if
things haven't changed, it makes good financial sense to keep in touch with your
adviser.

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

I'm pleased to report that over the past 12 months, the Nuveen national
municipal bond funds continued to perform well and meet their objectives of
providing attractive tax-free income and after-tax total returns. As of April
30, 1998, Class A shareholders in the Nuveen Municipal Bond Fund and the Nuveen
Insured Municipal Bond Fund were receiving SEC yields on net asset value of
4.33% and 4.06%, respectively. To match these yields, investors in the 31%
federal income tax bracket would have to earn 6.28% and 5.88% on taxable
alternatives. 

The declining interest rate environment over the past year had a significant
impact on the funds' performance. As the chart below illustrates, the yield on
the Bond Buyer 40, an unmanaged index of long-term municipal bonds, fell from
5.89% to 5.39% during the year. The decline reduced the funds' income levels, as
higher-yielding bonds that were called or sold from the portfolio had to be
replaced with bonds paying today's lower interest rates. As a result, the funds'
dividends were reduced slightly to reflect the level of income being earned by
the portfolios.

[Bond Buyer 40 chart appears here]

However, the decline in interest rates also had a positive impact on the funds
because many portfolio holdings appreciated in value during the period. Many of
the bonds in the portfolios have higher coupon rates than are available in
today's market, and the value of those bonds increased as rates trended
downward. The price appreciation resulting from this and other factors led to
the funds' strong total returns over the year.

The Economy in Review

The past 12 months were noteworthy for the ongoing performance of the equity
markets, which continued to exhibit remarkable strength. Fixed-income
investments also enjoyed bullish performance, as declining interest rates and
low inflation provided the ideal backdrop for a bond market rally. Much of the
decline in interest rates resulted from expectations that the financial problems
of Asia would restrain the prices of imported goods and reduce foreign demand
for U.S. products and services, thereby keeping inflation at moderate levels.
These inflation expectations were largely fulfilled, as the Consumer Price Index
rose only 1.4% for the 12 months ended April 1998, remaining at one of its
lowest levels in more than 30 years.

In coming months, we will continue to closely watch several key factors that are
likely to affect the future of the

economy, including demand for goods and services, changes in U.S. production
capacity, the availability of qualified employees, and stability of the money
supply. While it is still too early for the full impact of Asia's financial
difficulties to show up in U.S. economic statistics, the potential long-term
effect of this crisis on American markets is of special concern. We expect that
the development of these factors will continue to influence the tone of the
fixed-income markets during the remainder of the year.

Building Better Portfolios

As economic events unfold, we believe that many investors will find
diversification to be an increasingly important investment strategy. An
appropriately diversified portfolio that is invested in a variety of asset
classes that each react differently to changes in the economic environment can
help cushion your portfolio against risk.

Many investors select Nuveen municipal bond funds because their emphasis on
dependable tax-free income and attractive after-tax returns makes them ideal for
building and maintaining long-term financial security. These funds can work
together with other Nuveen investments to create the foundation of a
diversified, well-balanced portfolio. Recent studies by Nuveen Research have
demonstrated that balanced portfolios combining municipal bonds and stocks
provided superior after-tax returns and lower levels of risk compared with
portfolios of stocks and taxable bonds.

You and your financial adviser may want to consider combining your Nuveen
municipal bond fund with an investment in the new Nuveen European Value Fund, an
equity mutual fund that offers a portfolio of quality European company stocks
for investors seeking long-term growth and international diversification. This
fund is just one of an ever-expanding range of Nuveen products and services
designed to help investors achieve diversification while building a tax-
efficient, risk-sensitive investment portfolio. If you'd like to learn more
about the Nuveen European Value Fund or any of our other investments, contact
your financial adviser or call Nuveen Investor Services for a prospectus at
(800) 621-7227. Please read it carefully before you invest.

When seeking quality investment solutions that withstand the test of time, we
hope that you continue to think of John Nuveen & Co. On behalf of everyone at
Nuveen, I thank you for your continued confidence in us and our family of
investments.

Sincerely,

Nuveen Municipal Bond Fund

Portfolio Manager's Comments

Portfolio Manager Tom Spalding discusses the Nuveen Municipal Bond Fund
and reviews factors that affected performance over the past year.

Comments cover the one-year period ended April 30, 1998 and all performance
statistics are quoted for Class A shares.

Over the past 12 months, we have enjoyed a bull market in fixed-income
investments, including municipal bonds. As interest rates con continue to drop
and the nation's economy steams ahead, municipal bond new issue and refunding
activity has taken off, totaling $220 billion nationally in 1997 and more than
$68 billion in the first quarter of 1998, up 70% over the same period last year.
This environment afforded numerous opportunities to find value in the essential
services sector, especially among bonds issued by schools, water and sewer
districts, and hospitals. The bull market also brought volatility, as the
continued strength of the economy caused concern that robust growth would be
accompanied by higher inflation. This volatility also provided opportunities as
we took advantage of temporary dips in the market to find value.

As Tim mentioned in his letter to shareholders, the Nuveen Municipal Bond Fund
performed well over the past 12 months, generating a total return on net asset
value of 9.00%, which is equivalent to a taxable return of 11.32% for
shareholders in the 31% federal tax bracket. The total return is in line with
the 9.02% average annual return for the Lipper peer group of national municipal
bond funds. The fund also earned a five-star rating by Morningstar*,
demonstrating its outstanding record of delivering attractive risk-adjusted
total returns.

Fund Structure Contributes to Solid Performance

Since the fund's duration (a measure of price volatility in relation to changes
in interest rates) was shorter than that of the benchmark Lehman Index, 
careful security and sector selection allowed the fund to post competitive
returns with lower volatility. Longer duration funds are generally able to
participate more in market rallies and, conversely, suffer more during periods
of rising interest rates. This indicates that our fund management strategies
helped the fund perform in line with its peers without the risk of increased
volatility associated with a longer duration. Some of the strategies that paid
off for the fund during the year emphasized sector allocation, credit quality
and call protection.

Sector Allocation

The fund's two largest sector allocations are utility bonds and health care
bonds, accounting for 25% and 19%, respectively, of the fund's net assets. The
fund established its core position in health care bonds in the mid-1990s, when
uncertainty surrounding industry reform created opportunities for value
investing. At that time, we sought out bonds of fundamentally strong facilities
with competitive positions and healthy financial operations that were being
penalized by the uncertainty surrounding the industry. Since that time, the
health care debate has subsided and many of these bonds have been pre-refunded,
resulting in price stability and dependable income for the portfolio.

We see a similar opportunity in the public utility sector, with the relative
scarcity of new issuance and the restructuring of existing bonds making that
sector more attractive. The nationwide deregulation of the electric utility
sector has also provided numerous opportunities for value investing. We continue
to look for credits that will be dominant after the storm of deregulation has
passed, especially the bonds of those issuers who stand to benefit from
deregulation, including low-cost

providers with fundamentally sound financials and favorable customer bases. We
feel that our investment in this sector will provide the same upside potential
that health care bonds did a few years ago.

Credit Quality

As of April 30, 75% of the portfolio was invested in bonds rated AA or better.
Some of the fund's lower-rated credits have been pre-refunded as issuers took
advantage of lower interest rates. Currently, our preference is to add bonds
that are higher-rated since we believe the market does not offer adequate yield
compensation for the additional credit risk presented by lower-rated bonds.

Call Protection

Finally, the fund benefits from well-diversified call protection that will
heighten, in part, the fund's ability to maintain predictable income for
investors. Staggered call exposure helps protect the fund from reinvestment risk
in the event that interest rates cycle downward.


Strategies for the Future

We continue to manage the fund by focusing on the selection of undervalued
securities that provide both attractive income and the opportunity for price
appreciation relative to the market, consistent with the preservation of
capital. 

In the coming months, we will maintain a conservative approach to managing the
fund, maintaining a shorter duration than the market. If the yield curve remains
flat throughout the year, we will continue to seek maturities of less than 25
years, favoring bonds in the 15- to 20-year range. It is our opinion that in the
current environment, long-term yields are not high enough to warrant assuming
the additional interest rate risk associated with longer-maturity bonds.

Similarly, with the difference in the yields of higher- and lower-rated bonds at
such tight levels, we will continue to focus on higher-rated bonds.

* Overall rating within the municipal bond category for Class R shares for the
period ended 4/30/98. Morningstar proprietary ratings reflect historical risk-
adjusted performance and are subject to change every month. Ratings are
calculated from a fund's three-, five- and 10-year average annual returns in
excess of 90-day Treasury bill returns, with appropriate fee adjustments and a
risk factor that reflects fund performance below 90-day Treasury bill returns.
Class R shares of the fund earned five stars for each of the three-, five- and
10-year periods ended 4/30/98. In an investment category, 10% of funds receive
five stars. 1,547 municipal bond funds were rated for the three-year period, 809
for the five-year period and 346 for the 10-year period, each ending 4/30/98.

Nuveen Insured Municipal Bond Fund

Portfolio Manager's Comments

Portfolio Manager Steve Krupa discusses the Nuveen Insured Municipal Bond Fund
and reviews factors that affected performance over the past year.

Comments cover the one-year period ended April 30, 1998 and all performance
statistics are quoted for Class A shares.


Over the past 12 months, we have enjoyed a bull market in fixed-income
investments, including municipal bonds. As interest rates continue to drop and
the nation's economy steams ahead, municipal bond new issue and refunding
activity has taken off, totaling $220 billion nationally in 1997 and more than
$68 billion in the first quarter of 1998, up 70% over the same period last year.
This environment afforded numerous opportunities to find value in the essential
services sector, especially among bonds issued by schools, water and sewer
districts, and hospitals. The bull market also brought volatility, as the
continued strength of the economy caused concern that robust growth would be
accompanied by higher inflation. This volatility also provided opportunities as
we took advantage of temporary dips in the market to find value.

The Nuveen Insured Municipal Bond Fund turned in strong performance over the
past 12 months, beating its Lipper peer average return of 8.46% and ranking 10th
out of 51 insured municipal bond funds. During a period of declining interest
rates and appreciating bond prices, the fund's total return performance of 9.05%
slightly under-performed the benchmark Lehman Index return of 9.67% because the
fund's average duration (a measure of its price volatility in relation to
changes in interest rates) was shorter than that of the Lehman Index. Longer
duration funds are generally able to participate more in market rallies and,
conversely, suffer more during periods of rising interest rates. However, our
other fund management strategies helped the fund perform well without the risk
of increased volatility associated with a longer duration.

Pre-Refunding and High Embedded Yields Keep Trading to a Minimum
As interest rates declined, a record number of bond issuers advance refunded
their debt obligations. These bonds are then secured by U.S. government
securities until the bonds are called. This pre-refunding activity keeps the
credit quality of the portfolio high and the coupon payments stable, but
moderates participation in bond rallies. Whenever possible, we sold pre-refunded
bonds that were expected to be called in the next 18 months and replaced them
with longer-term bonds to help lengthen the duration of the fund.

In addition, we limited bond sales to maximize after-tax total return. Many of
the longer-term bonds with high yields have appreciated in value and would
trigger significant capital gains if they were sold. As a result, we held bonds
with higher embedded yields to protect investors from return-reducing tax
liabilities.

Fund Will Continue to Focus on Boosting Current Yield and Total Return
In the coming months, we plan to increase the amount of AMT bonds in the
portfolio. AMT bonds -- those subject to the alternative minimum tax -- are
issued with higher yields than other types of bonds, helping to support a higher
income.

Another strategy that should help boost the total return for investors will be
the fund's increased exposure to health care bonds. The fund holds a core
position in health care bonds because uncertainty surrounding industry reform
created numerous opportunities for value investing. We seek bonds of
fundamentally strong facilities with competitive positions and healthy financial
operations that are undervalued by the market.

<PAGE>
 
We also see similar opportunity in the public utility sector as deregulation
makes this sector appear undervalued. We continue to look for credits that will
remain dominant after deregulation, emphasizing the bonds of issuers who stand
to benefit from deregulation as low-cost providers with fundamentally sound
financials and favorable customer bases. We feel that this sector will also
provide upside potential.

Additional Strategies for the Future
We continue to manage the fund by focusing on the selection of undervalued
securities that provide both attractive income and the opportunity for price
appreciation relative to the market, consistent with the preservation of
capital.

The primary focus of the fund will continue to be call protection -- helping to
maintain a stable dividend for investors. The fund benefits from well-
diversified call protection that will heighten, in part, the fund's ability to
maintain a dependable income level. Less than 6% of the total portfolio is
subject to call prior to the year 2001. Staggered call exposure helps protect
the fund from reinvestment risk in the event that interest rates cycle downward.

Finally, we'll continue to purchase hospital and public power bonds that Nuveen
Research feels are well positioned in the current deregulation environment.

   reflects Class R share performance adjusted for differences in expenses,
   which are primarily differences in distribution and service fees.

Report of Independent Public Accountants


To the Board of Trustees and Shareholders of
Nuveen Flagship Municipal Trust:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of the Nuveen Municipal Bond Fund and Nuveen Insured
Municipal Bond Fund (two of the portfolios constituting the Nuveen Flagship
Municipal Trust (a Massachusetts business trust)), as of April 30, 1998, and the
related statements of operations, statements of changes in net assets and the
financial highlights for the periods indicated thereon. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of April
30, 1998, by correspondence with the custodian and brokers. As to securities
purchased but not received, we requested confirmation from brokers and, when
replies were not received, we carried out alternative auditing procedures. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Municipal Bond Fund and Nuveen Insured Municipal Bond Fund of the Nuveen
Flagship Municipal Trust as of April 30, 1998, and the results of their
operations, the changes in their net assets and their financial highlights for
the periods indicated thereon in conformity with generally accepted accounting
principles.

Notes to Financial Statements




1. General Information and Significant Accounting Policies

The Nuveen Flagship Municipal Trust (the "Trust") is an open-end diversified
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises the Nuveen Municipal Bond Fund ("Municipal Bond")
and the Nuveen Insured Municipal Bond Fund ("Insured Municipal Bond")
(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, Municipal Bond and Insured
Municipal Bond were reorganized into the Trust. Prior to the reorganization,
Municipal Bond was a Massachusetts Business Trust and Insured Municipal Bond was
a series of the Nuveen Insured Tax-Free Bond Fund, Inc., each an open-end
diversified management investment company. As part of this reorganization, the
Funds changed their fiscal year ends from February 28 to April 30.

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 the when-issued and delayed delivery purchase
commitments. At April 30, 1998, Insured Municipal Bond had outstanding delayed
delivery purchase commitments of $4,314,278. Municipal Bond 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 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 carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and 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.

<PAGE>
 
Federal 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 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 income tax, to
retain such tax-exempt status when distributed to the shareholders of the Funds.
All monthly tax-exempt income dividends paid during the fiscal year ended April
30, 1998, have been designated Exempt Interest Dividends. Net realized capital
gain and market discount distributions are subject to federal taxation.


Insurance

Insured Municipal Bond 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 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
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 fiscal year ended April 30, 1998.


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.

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. government or U.S. government agency
securities, either of which ensure the timely payment of principal and interest
in the event of default (29% for Municipal Bond and 100% for Insured Municipal
Bond). Such insurance or escrow, however, does not guarantee the market value
of the municipal securities or the value of the Funds' shares (see note 1). 

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Fund.

As of April 30, 1998
For Class A shares on net asset value


* Overall rating within the municipal bond category for Class A shares for the
  period ended 4/30/98. Morningstar proprietary ratings reflect historical risk-
  adjusted performance and are subject to change every month. Ratings are
  calculated from a fund's three-, five- and 10-year average annual returns in
  excess of 90-day Treasury bill returns, with appropriate fee adjustments and a
  risk factor that reflects fund performance below 90-day Treasury bill returns.
  Class A shares of all three funds earned four stars for each of the three- and
  five-year periods ended 4/30/98, and for the 10-year period for the Limited
  Term fund. In an investment category, 10% of funds receive five stars and
  22.5% receive four stars. 1,547 municipal bond funds were rated for the three-
  year period, 809 for the five-year period, and 346 for the 10-year period,
  each ended 4/30/98.

Is it Time for a Financial Check-Up?

Now is a great time to sit down with your financial adviser and review your
financial plan. How can you make sure that your investment strategy is strong
enough to provide the income you need today and versatile enough to change as
your goals do? Here are some guidelines:

 . Make sure you and your adviser understand your current situation. How have
  your goals, objectives and risk profile changed? What are your current tax
  concerns, interests, lifestyle?

 . Revisit your current investment choices. If the value of one portion of your
  portfolio has grown substantially, it may be time to rebalance asset classes.

 . Determine how your asset mix will be implemented. Changing your asset
  allocation is generally a gradual process. Make sure you and your adviser have
  a clear understanding of each other's responsibilities. Define and discuss
  what you want in terms of support from your adviser.

 . Keep revisiting your plan. Don't assume that once you've revised your plan and
  reallocated your portfolio the process is finished.

It's recommended that you meet at least once a year with your financial adviser-
and usually more if there have been significant changes in interest rates, tax
laws, retirement plan distributions, lifestyle or health.

Even if things haven't changed, it makes good financial sense to keep in touch
with your adviser.

Dear Shareholder

Chairman of the Board

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

I'm pleased to report that over the past 12 months, the Nuveen national
municipal bond funds continued to perform well and meet their objectives of
providing attractive tax-free income and after-tax performance. Once again, all
three funds generated competitive yields and were ranked in the top 10 percent
of their respective Lipper peer groups based on their outstanding total returns.
Each fund also received a four-star rating by Morningstar, demonstrating strong
risk-adjusted performance in addition to the superior overall performance
recognized by Lipper.

The declining interest rate environment over the past year had a significant
impact on the funds' performance. As the chart below illustrates, the yield on
the Bond Buyer 40, an unmanaged index of long-term municipal bonds, fell from
5.89% to 5.39% during the year. The decline reduced the income levels of the 
All-American and Intermediate funds, as higher-yielding bonds that were called
or sold from the portfolios had to be replaced with bonds paying today's lower
interest rates. As a result, the dividends for these funds were reduced to
reflect the levels of income being earned by the portfolios. The Limited Term
fund's income was not impacted during the period because its low turnover and
good call protection supported the dividend through the low interest rate
environment. In addition, the accumulation of income from higher-yielding bonds
purchased over the past couple of years allowed us to increase its dividend
during the period.

[Bond Buyer 40 Chart Appears Here]

The decline in interest rates also led to many portfolio holdings appreciating
in value during the year. Many of the bonds in the portfolios have higher coupon
rates than are available in today's market, and the value of those bonds
increased as rates trended downward. The price appreciation resulting from this
and other factors led to the fund's outstanding total returns over the year.

The Economy in Review
The past 12 months were noteworthy for the ongoing performance of the equity
markets, which continued to exhibit remarkable strength. Fixed-income
investments also enjoyed bullish performance, as declining interest rates and
low inflation provided the ideal backdrop for a bond market rally. Much of the
decline in interest rates resulted from expectations that the financial problems
of Asia would restrain the prices of imported goods and reduce foreign demand
for U.S. products and services, thereby keeping inflation at moderate levels.
These inflation expectations were largely fulfilled, as the Consumer Price Index

rose only 1.4% for the 12 months ended April 1998, remaining at one of its
lowest levels in more than 30 years.

In coming months, we will continue to closely watch several key factors that are
likely to affect the future of the economy, including demand for goods and
services, changes in U.S. production capacity, the availability of qualified
employees, and stability of the money supply. While it is still too early for
the full impact of Asia's financial difficulties to show up in U.S. economic
statistics, the potential long-term effect of this crisis on American markets is
of special concern. We expect that the development of these factors will
continue to influence the tone of the fixed-income markets during the remainder
of the year.

Building Better Portfolios

As economic events unfold, we believe that many investors will find
diversification to be an increasingly important investment strategy. An
appropriately diversified portfolio that is invested in a variety of asset
classes that each react differently to changes in the economic environment can
help cushion your portfolio against risk.

Many investors select Nuveen municipal bond funds because their emphasis on
dependable tax-free income and attractive after-tax returns makes them ideal for
building and maintaining long-term financial security. These funds can work
together with other Nuveen investments to create the foundation of a
diversified, well-balanced portfolio. Recent studies by Nuveen Research have
demonstrated that balanced portfolios combining municipal bonds and stocks
provided superior after-tax returns and lower levels of risk compared with
blends of stocks and taxable bonds.

You and your financial adviser may want to consider combining your Nuveen
municipal bond fund with an investment in the new Nuveen European Value Fund, an
equity mutual fund that offers a portfolio of quality European company stocks
for investors seeking long-term growth and international diversification. This
fund is just one of an ever-expanding range of Nuveen products and services
designed to help investors achieve diversification while building a tax-
efficient, risk-sensitive investment portfolio. If you'd like to learn more
about the Nuveen European Value Fund or any of our other investments, contact
your financial adviser or call Nuveen Investor Services for a prospectus at
(800) 621-7227. Please read it carefully before you invest.

When seeking quality investment solutions that withstand the test of time, we
hope that you continue to think of John Nuveen & Co. On behalf of everyone at
Nuveen, I thank you for your continued confidence in us and our family of
investments.

Sincerely,

Nuveen Flagship All-American Municipal Bond Fund

Portfolio Manager's Comments

Rick Huber, portfolio manager of the All-American fund, talks about the
municipal market over the past year and the performance of the fund.

Comments cover the one-year period ended April 30, 1998 and all
performance statistics are quoted for Class A shares on net asset value.



The Year in Review

Over the past 12 months, we have enjoyed a bull market in fixed-income
investments, including municipal bonds. Bond prices rose as interest rates
continued to drop and inflation remained at 30-year lows. However, the
performance of the municipal market was moderated by the effect of heavy supply,
as the lower rate environment stimulated a substantial increase in new issuance
as well as the refinancing of existing bonds. The first quarter of 1998 saw $68
billion of new municipal issuance, up 70% from the same period in 1997.

The flood of new issues continued in recent weeks with May's long-awaited sale
of the first segment of Long Island (New York) Power Authority's $7 billion
offering, the largest issuance in municipal bond history. The publicity
surrounding this issue brought an unusual level of attention to the municipal
market and may stimulate additional interest in municipal bonds.

Investment Objective

The All-American fund is a long-term municipal bond fund that seeks to provide a
high level of current income consistent with capital preservation. The fund
invests in a nationally diversified portfolio of investment-grade quality
municipal bonds with an average maturity of 15-30 years. Nuveen follows a
disciplined investment process and tax-conscious portfolio management strategies
that emphasize competitive tax-free income and attractive after-tax total
returns over time.

Fund Performance

Once again, the All-American fund was an exceptional performer by every measure.
Its 10.32% total return outperformed the Lehman Brothers Municipal Bond Index
return by more than 100 basis points, as well as its Lipper peer group average
return of 9.02%. The fund was ranked in the top 10 percent of national municipal
bond funds by Lipper (16th of the 237 funds in the grouping), and earned a four-
star rating by Morningstar. The fund's distribution yield of 5.19% is one of the
most competitive dividend rates in its category (SEC yield was 4.52% for the
same period). Shareholders in the 31% federal income tax bracket would have had
to earn at least 7.52% on a comparable taxable investment to equal the All-
American fund's distribution yield on a taxable equivalent basis (or 6.55% to
equal the SEC yield).

Income Levels

The fund has performed well during this period of declining interest rates,
although its dividend had to be reduced in January to compensate for the lower
levels of income produced when cash inflows and proceeds from called and sold
bonds were used to purchase bonds paying today's lower rates. However, the fund
continues to pay competitive dividend rates because our in-depth research allows
us to find those higher-yielding and undervalued bonds that perform well
throughout market cycles.

Price Appreciation

Our careful research also helped us purchase bonds that appreciated in value due
to credit upgrades and pre-refundings. Over the past year, a large percentage of
the bonds in the portfolio were pre-refunded by their issuers. In a pre-
refunding, bonds are essentially paid off by their issuer and backed by U.S.
Treasury securities until they can be called from the portfolio. The pre-
refunding increases the credit quality of the bond significantly, and it
appreciates in value as a result. This price appreciation accounts for a large
percentage of the growth in total return over the past year. Other

bonds in the portfolio increased in value because their credit ratings were
upgraded during the year. Credit upgrades were common throughout 1997 and the
first quarter of 1998 as the financial conditions of many municipalities
improved with the booming economy.

Strategies Over the Past Year
Maintaining the income level of the fund has been a priority over the past year.
To meet our goal of sustaining a competitive dividend, one focus has been on
call protection, which helps reduce the volatility of the income stream by
ensuring that only a small percentage of bonds could be called away from the
portfolio at any one time. In our efforts to improve the call protection of the
fund, we searched for bonds that have attractive call features or are not
callable at all. This ensures that if interest rates remain steady or continue
to drop, the higher-paying bonds in the portfolio will not be called away
immediately and will remain in the portfolio generating competitive income
levels unless we choose to sell them.

Another strategy over the past year was to purchase shorter-duration bonds with
maturities of 15-20 years. We felt that this was an excellent area of value in
the municipal bond market because these bonds offered attractive income levels
compared to their historical levels of volatility. Duration is a measure of
price volatility in relation to changes in interest rates. Longer-duration
bonds, which tend to be more volatile, offered little incremental yield for
taking on the additional interest rate risk they carry. Also, with shorter-
duration bonds, the fund should be less affected by interest rate movements.
Although it would be less affected by a market downturn, the shorter-duration
fund will also be less able to participate in a market rally.

We also increased our holdings of health care bonds during the year, reflecting
the value opportunities we saw in this sector, particularly in hospital and 
long-term care bonds. Health care bonds now represent 17% of the portfolio, the
fund's largest holding. When we purchased these bonds, they offered good yields
and the potential for price appreciation. Since that time, many of these bonds
have been pre-refunded or have increased in value due to other factors such as
credit upgrades.

Outlook for the Future
In the coming months, we plan to manage the fund more conservatively, and will
work toward a shorter duration.

In addition, we plan to reposition the credit quality of the fund during the
next year. Currently, the fund is heavily weighted in the lower categories of
investment-grade quality bonds, with 44% in BBB and non-rated bonds. However, we
plan to replace many of these lower-rated bonds with bonds that have higher
credit ratings. At present, credit spreads remain tight, meaning that the
difference in yields between higher-rated and lower-rated bonds is unusually
small. By purchasing higher-rated bonds, we will increase the credit quality of
the fund with little impact on the fund's income levels. We anticipate that
credit spreads will widen again and that the higher-rated bonds will increase in
value as a result. Higher-rated bonds will also help us position the fund more
conservatively since they are less subject to market fluctuations.

Nuveen Flagship Intermediate Municipal Bond Fund

Portfolio Manager's Comments


Paul Brennan, portfolio manager of the Intermediate fund, talks about the
municipal market over the past year and the performance of the fund.

Comments cover the one-year period ended April 30, 1998 and all
performance statistics are quoted for Class A shares on net asset value.



The Year in Review

Over the past 12 months, we have enjoyed a bull market in fixed-income
investments, including municipal bonds. Bond prices rose as interest rates
continued to drop and inflation remained at 30-year lows. However, the
performance of the municipal market was moderated by the effect of heavy supply,
as the lower rate environment stimulated a substantial increase in new issuance
as well as the refinancing of existing bonds. The first quarter of 1998 saw $68
billion of new municipal issuance, up 70% from the same period in 1997.

The flood of new issues continued in recent weeks with May's long-awaited sale
of the first segment of Long Island (New York) Power Authority's $7 billion
offering, the largest issuance in municipal bond history. The publicity
surrounding this issue brought an unusual level of attention to the municipal
market and may stimulate additional interest in municipal bonds.

Investment Objective

The Intermediate fund is an intermediate-term municipal bond fund that seeks a
balance of current income and capital preservation potential. The fund invests
in a nationally diversified portfolio of investment-grade municipal bonds with
an average maturity of 5-10 years. Nuveen follows a disciplined investment
process and tax-conscious portfolio management strategies that emphasize
competitive tax-free income and attractive after-tax total returns over time.

Fund Performance

The fund performed exceptionally well compared with its benchmark and peer
group. Its total return of 8.97% outperformed the Lehman 7-Year Municipal Bond
Index return of 7.84%, and surpassed its Lipper peer group average by almost 200
basis points. The fund was ranked in the top five percent of national
intermediate municipal bond funds by Lipper (fifth of the 139 funds in the
grouping) and received a four-star rating by Morningstar.

Although the fund posted these outstanding results for the year, it experienced
a dividend reduction in April as a result of the declining interest rate
environment. As interest rates fell over the past year, we had to replace bonds
that were called or sold with bonds paying today's lower interest rates. With
its resulting lower income levels, the fund's dividend was adjusted to align
with its income rate.

Strategies Over the Past Year

Maturity and Duration

We achieved this outstanding performance by purchasing securities at the longer
end of the intermediate-term maturity spectrum and were rewarded as interest
rates dropped and these bonds outperformed shorter maturity bonds on a relative
scale. The fund maintained a significantly longer duration than its benchmark
and peer group (6.79 average weighted duration compared with 5.42 for the Lehman
7-Year Index), which was an important factor in performance. Duration is a
measure of the fund's price volatility in relation to changes in interest rates.
With a longer duration, the Intermediate fund was better able to participate in
this year's market rally. However, it would also have been more adversely
affected had the bond market experienced a downturn.

6
<PAGE>
 
Call Protection

During the year, we structured the fund to maintain superior call protection by
purchasing bonds with favorable call provisions as well as those that are not
callable at all. This ensures that if interest rates remain steady or continue
to drop, the higher-paying bonds in the portfolio will not be called away
immediately and will remain in the portfolio generating competitive income
levels unless we choose to sell them. Call protection helps ensure a more stable
dividend and also helped the fund outperform its peers as interest rates fell
and many similar funds experienced bond calls that adversely affected their
income levels.

Undervalued Securities

By leveraging Nuveen's award-winning research department, we were able to find
undervalued bonds that also contributed to the fund's strong performance. For
example, many of the bonds in the portfolio were pre-refunded during the year.
In a pre-refunding, bonds are essentially paid off by their issuer and backed by
U.S. Treasury securities until they can be called from the portfolio. The pre-
refunding increases the credit quality of the bond significantly, and it
appreciates in value as a result. This price appreciation accounted for a
significant percentage of the fund's total return over the past year.

Research also helped us maintain a competitive dividend during the year by
allowing us to find lower-rated, higher-yielding bonds. The incremental yield
offered by these higher-yielding bonds contributed to the fund's strong
dividend. We also took advantage of Nuveen's research team to find undervalued
securities in the health care sector. The fund has a relatively heavy weighting
in this sector, which offers competitive yields and good potential for price
appreciation.

Outlook for the Future

In the coming months, we will continue to utilize the same strategies that led
to such strong performance for the fund over the last year. Since income is a
top objective of the fund, we will work toward maintaining superior call
protection and helping ensure the strength of the dividend. In addition, we will
continue to maintain a relatively long duration compared with the benchmark
Lehman 7-Year Index. This means more volatility for the fund should interest
rates fluctuate, but also will ensure that the fund is able to maximize its
participation in any potential market rallies.

investments, including municipal bonds. Bond prices rose as interest rates
continued to drop and inflation remained at 30-year lows. However, the
performance of the municipal market was moderated by the effect of heavy supply,
as the lower rate environment stimulated a substantial increase in new issuance
as well as the refinancing of existing bonds. The first quarter of 1998 saw $68
billion of new municipal issuance, up 70% from the same period in 1997.

The flood of new issues continued in recent weeks with May's long-awaited sale
of the first segment of Long Island (New York) Power Authority's $7 billion
offering, the largest issuance in municipal bond history. The publicity
surrounding this issue brought an unusual level of attention to the municipal
market and may stimulate additional interest in municipal bonds.

Investment Objective

The Limited Term fund is a short/intermediate-term municipal bond fund that
seeks current income consistent with a high level of capital preservation. The
fund invests in a nationally diversified portfolio of investment-grade municipal
bonds with an average maturity of one to seven years. Nuveen follows a
disciplined investment process and tax-conscious portfolio management strategies
that emphasize competitive tax-free income and attractive after-tax total
returns over time.

Fund Performance
The Limited Term fund performed well, generating a competitive dividend and
total return compared with its peers. The fund's total return of 6.67%
outperformed its Lipper peer group of national short/intermediate-term municipal
bond funds by 138 basis points and was ranked second of the 34 funds in the
grouping for the year. The fund essentially paralleled the unmanaged Lehman
Brothers 5-Year Municipal Bond Index return of 6.73% and was given a four-star
rating by Morningstar. During a period when many municipal bond funds
experienced dividend reductions due to the lower interest rate environment, the
dividend for the Limited Term fund actually increased during the period. Through
foresight and strategic management, we structured the fund so that we locked in
good yields and a relatively high income stream that could support the dividend
through this lower interest rate environment.

Although the Limited Term fund is a relatively conservative municipal bond fund
when compared with the other longer-term Nuveen funds in this report, its strong
performance was achieved through a more aggressive management strategy than most
shorter-term municipal bond funds undertake. It has a relatively heavy weighting
in higher-yielding BBB and non-rated bonds and maintains a longer duration than
many short-term funds.

Duration is a measure of the price volatility of the fund in relation to a
change in interest rates. Longer duration funds are better able to participate
in a market rally, but will suffer more in a down market. Although the fund is
subject to more volatility than its peers with shorter maturities and durations,
it provides an excellent opportunity for more conservative investors who want to
invest in the municipal bond market for the shorter-term with less price
volatility and greater income stability than can be found with longer-term
funds.

Strategies Over the Past Year

During the past year, our research-intensive bond selection process allowed us
to find opportunities throughout the country to enhance the yield and
performance potential of the fund. We found value in a range of maturities,
regions and sectors, including the health care industry. The portfolio was
heavily weighted in health care securities because the tremendous amount of
issuance in that sector forced issuers to offer attractive yields. The fund also
benefited as health care bonds, particularly those issued by long-term care
providers, appreciated in value during the year. However, we feel that we have
maximized our opportunities in the health care sector for now, so we will be
looking for ways to diversify the fund more in other sectors of the municipal
market in the coming months.

Outlook for the Future

During the coming year, we plan to take a more conservative approach to managing
the fund, including repositioning its credit quality. Currently, the fund is
heavily weighted in the lower categories of investment-grade quality bonds, with
32% in BBB and non-rated bonds. However, we plan to replace many of these lower-
rated bonds with bonds that have higher credit ratings. At present, credit
spreads remain tight, meaning that the difference in yields between higher-rated
and lower-rated bonds is unusually small. By purchasing higher-rated bonds, we
will increase the credit quality of the fund without significantly impacting
current income levels. We anticipate that credit spreads will widen again and
that the higher-rated bonds will increase in value as a result. Higher-rated
bonds will help us position the fund more conservatively since they are less
subject to market fluctuations.

1  Class A share returns are actual. Class C and R share returns are actual for
the period since class inception; returns prior to class inception are Class A
share returns adjusted for differences in sales charges and expenses, which are
primarily differences in distribution and service fees. Class A shares have a
2.5% maximum sales charge. 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 federal income tax rate of 31%. Represents the yield
on a taxable investment necessary to equal the yield of the Nuveen fund on an
after-tax basis.

3  The Index Comparison shows the change in value of a $10,000 investment in the
Class A shares of the Nuveen fund compared with the Lehman Brothers 5-Year and
10-Year Municipal Bond Indexes. In the past, the fund's performance was compared
against the Lehman 10-Year Municipal Bond Index. Begining this year, we will
compare the fund's performance with the Lehman 5-Year Municipal Bond Index,
which can now be used as a 10-year comparison and better corresponds to the
fund's investment policies. The Lehman Municipal Bond Indexes are comprised of a
broad range of investment-grade municipal bonds, and do not reflect any initial
or ongoing expenses. The Nuveen fund return depicted in the chart reflects the
initial maximum sales charge applicable to A shares (2.5%) and all ongoing fund
expenses.

Notes to Financial Statements



1. General Information and Significant Accounting Policies

The Nuveen Flagship Municipal Trust (the "Trust") is an open-end diversified
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises the Nuveen Flagship All-American Municipal Bond
Fund ("All-American"), the Nuveen Flagship Intermediate Municipal Bond Fund
("Intermediate") and the Nuveen Flagship Limited Term Municipal Bond Fund
("Limited Term") (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, Flagship All-American Tax
Exempt Fund ("Flagship All-American"), Flagship Intermediate Tax Exempt Fund
("Flagship Intermediate") and Flagship Limited Term Tax Exempt Fund ("Flagship
Limited Term") were reorganized into the Trust. At this time they were renamed
Nuveen Flagship All-American Municipal Bond Fund, Nuveen Flagship Intermediate
Municipal Bond Fund and Nuveen Flagship Limited Term Municipal Bond Fund,
respectively. The Funds had a May 31 fiscal year end prior to being reorganized
into the Trust and now have an April 30 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 the when-issued and delayed delivery purchase commitments. At
April 30, 1998, All-American had outstanding when-issued and delayed delivery
purchase commitments of $11,918,204. Intermediate and Limited Term 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 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 carryforwards.

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.

Federal 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 income tax, to retain such tax-exempt status when
distributed to the shareholders of the Funds. All monthly tax-exempt income
dividends paid during the fiscal year ended April 30, 1998, have been designated
Exempt Interest Dividends. Net realized capital gain and market discount
distributions are subject to federal taxation.

Flexible Sales Charge Program

Each Fund offers Class A, C and R Shares. All-American 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 fiscal year ended April 30, 1998.

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.

The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Trust pays no
compensation directly to those of 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 or its affiliates.

The Adviser may voluntarily reimburse expenses from time to time, which may be
terminated at any time at its discretion.

During the fiscal year ended April 30, 1998, the Distributor collected sales
charges on purchases of Class A Shares of approximately $585,700, $91,500 and
$367,200 for All-American, Intermediate and Limited Term, respectively, of which
approximately $529,400, $76,400 and $357,500, 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 fiscal year ended April 30, 1998, the Distributor compensated
authorized dealers directly with approximately $547,800, $17,700 and $593,100 in
commission advances at the time of purchase for All-American, Intermediate and
Limited Term, respectively. To compensate for commissions advanced to authorized
dealers, all 12b-1 service fees collected on Class B Shares for All-American
during the first year following a purchase, all 12b-1 distribution fees on Class
B Shares for All-American, 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 fiscal year ended April 30, 1998, the Distributor
retained approximately $154,900, $9,600 and $78,600 in such 12b-1 fees for All-
American, Intermediate and Limited Term, 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 $23,400, $6,600 and $80,800 of CDSC on
share redemptions for All-American, Intermediate and Limited Term, respectively,

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. government or U.S. government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default (24% for All-American, 24% for Intermediate and 34% for
Limited Term). Such insurance or escrow, however, does not guarantee the market
value of the municipal securities or the value of any of the Funds' shares.

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Fund.

Report of Independent Public Accountants



To the Board of Trustees and Shareholders of
Nuveen Flagship Municipal Trust:

We have audited the accompanying statements of net assets, including the
portfolios of investments, of Nuveen Flagship All-American Municipal Bond Fund,
Nuveen Flagship Intermediate Municipal Bond Fund, and Nuveen Flagship Limited
Term Municipal Bond Fund (collectively, the "Funds") (three of the portfolios
constituting the Nuveen Flagship Municipal Trust (a Massachusetts business
trust)), as of April 30, 1998, the related statements of operations, statements
of changes in net assets and the financial highlights for the year then ended.
These financial statements and financial highlights are the responsibility of
the Funds' management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits. The financial
statements and financial highlights for the Funds for the years ended April 30,
1997 and prior were audited by other auditors whose report dated June 13, 1997,
expressed an unqualified opinion on those financial statements and financial
highlights.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of April
30, 1998, by correspondence with the custodian and brokers. As to securities
purchased but not received, we requested confirmation from brokers and, when
replies were not received, we carried out alternative auditing procedures. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of the Nuveen
Flagship All-American Municipal Bond Fund, Nuveen Flagship Intermediate
Municipal Bond Fund, and Nuveen Flagship Limited Term Municipal Bond Fund of the
Nuveen Flagship Municipal Trust as of April 30, 1998, and the results of their
operations, the changes in their net assets, and the financial highlights for
the year then ended, in conformity with generally accepted accounting
principles.
