[graphic omitted]   DEAR SHAREHOLDER;

                    The past six months were marked by volatility in the
                    government bond market. Interest rates and bond prices
                    seesawed during the period in response to a variety of
                    domestic and foreign factors. Uncertainty about the U.S.
                    economy's ability to grow prompted a series of interest-rate
                    cuts by the Federal Reserve Bank in the fall of 1998. This
                    triggered a strong fourth-quarter rally in U.S. bond
markets. The first two months of 1999 proved more difficult as interest rates
rose and bond prices fell. As a result, bond prices ended the period slightly
below where they began.

Continued economic and financial trouble abroad made "flight-to-quality" a
dominant theme during the period. Problems in Asia, Russia and Latin America
caused investors worldwide to seek the relative stability of U.S. Treasury
bonds. A lower rate of bond issuance due to a federal budget surplus and
increased foreign demand further supported bond prices.

The Funds' managers actively managed each portfolio in response to variable
conditions in the bond market during the period. For the six months ended
February 28, 1999, Class A shares of each fund generated the following returns,
based on net asset value (NAV):

Colonial Short Duration U.S. Government Fund:   1.50%

Colonial Intermediate U.S. Government Fund:     0.58%

Colonial Federal Securities Fund:               0.01%

As always, we thank you for choosing one of Colonial's Government Funds for your
portfolio and for giving us the opportunity to serve your investment needs.

Respectfully, 


/s/ Stephen E. Gibson
Stephen E. Gibson, President
April 12, 1999





IMPORTANT NOTES: 

Returns and value of an investment will vary resulting in a gain or a loss on
sale.

All results shown assume reinvestment of distributions. Net asset value (NAV)
returns do not include sales charges or contingent deferred sales charges
(CDSC).

Public offering price (POP) returns include the maximum initial sales charge:

For Colonial Short Duration U.S. Government Fund: 3.25%. For Colonial
Intermediate U.S. Government Fund and Federal Securities Fund: 4.75%.

The CDSC returns reflect the maximum sales charge on the following schedule:

For Colonial Short Duration U.S. Government Fund: 4% for 1 year on Class B
shares, 1% for 1 year on Class C shares. For Colonial Intermediate U.S.
Government Fund and Federal Securities Fund: 5% for 1 year and 2% for 5 years on
Class B shares, 1% for 1 year on Class C shares.

If the Advisor or its affiliates had not borne or waived certain Fund expenses,
total returns would have been lower. Performance for different share classes
will vary based on the differences in sales charges and fees associated with
each class. Because the Funds are actively managed, there can be no guarantee
the Funds will continue to maintain the portfolio structure and average life
shown in the future.

Because market conditions change frequently, there can be no assurance that the
trends described in this report will continue.

Portfolio Managers' Report

THE MARKET ENVIRONMENT FOR GOVERNMENT BONDS

WHEN YOU CONSIDER BOTH RISK AND RETURN POTENTIAL, TREASURY BONDS HAVE BEEN
ATTRACTIVE FOR SEVERAL REASONS:

1. REAL RATES OF RETURN HAVE BEEN HIGH. While yields are not as high as they
have been in the past, inflation is at its lowest point in 40 years. This means
that your real rate of return (investment return less inflation) may be higher
today than in the early '90s, when interest rates were higher.

2. U.S. GOVERNMENT SECURITIES HAVE PROVIDED A HAVEN FOR FOREIGN INVESTORS.
Yields on U.S. Treasurys are higher than many foreign equivalents. This, coupled
with a stable currency, makes Treasurys an attractive option for foreign
investors.

3. DECLINING SUPPLY OF GOVERNMENT BONDS. The federal budget surplus has reduced
the U.S. Treasury's need to issue bonds. As supply decreases, the demand for
these bonds may drive interest rates down and prices upward, which could in turn
produce attractive appreciation potential for investors.



INFLATION VS. A 10-YEAR TREASURY NOTE 1989 TO 1999

Today's interest rates may seem low. However, when you compare real rates of
return over the last 10 years, you will see that your post-inflation return is
higher today than when interest rates were over 8% in the early '90s.

Portfolio Managers' Report

WHAT IS DURATION?

Duration is a measure of a bond mutual fund's price sensitivity to interest rate
movements. It is a mathematical calculation that assesses such factors as the
maturities of the bonds in a fund's portfolio, coupon rates and how often they
are paid, and prevailing market interest rates. In government bond funds,
interest rate risk is the primary consideration. Therefore, the specific
benefits and risks of these funds vary by their duration.

ACTIVE MANAGEMENT RESPONDS TO CHALLENGING MARKET CONDITIONS

BASED ON OUR OUTLOOK FOR INTEREST RATES, OUR PRIMARY STRATEGY WAS TO MANAGE
DURATION, ESPECIALLY IN MORTGAGE-BACKED SECURITIES. We shortened mortgage
security durations early in the period because of a sudden decline in interest
rates and heightened fears of rising prepayments. At the same time, we increased
the duration of other Funds' holdings to maintain an overall portfolio duration
that was within in each Fund's targeted level.

However, once interest rates began to rise again, we reduced our exposure to
Treasurys to offset an increase in duration of mortgage securities. Overall, we
lengthened the Portfolios' durations during the period to compensate for our
mortgage sector weightings.

COLONIAL SHORT DURATION U.S. GOVERNMENT FUND

Investing primarily in U.S. government securities, the Fund is managed for low
price volatility. It is the most conservative of Colonial's three government
funds, designed for investors with a short investment horizon or low-risk
tolerance.

As interest rates increased, particularly during the first two months of 1999,
we increased the Fund's duration from 1.8 to 2.3 years, primarily by increasing
our exposure to mortgage-backed securities from 27% to 36% and decreasing our
holdings in U.S. agency debt and cash. This shift allowed the portfolio to take
advantage of higher interest rates and to position the Fund for greater price
appreciation potential.

Adjustable-rate mortgages experienced high prepayments due to a decline in
interest rates early in the period. As a result, we increased the Fund's
mortgage-backed exposure through the purchase of fixed-rate securities. However,
we saw prepayments slow when interest rates began to rise in 1999.

Our strategy to increase mortgage-backed securities in the portfolio hampered
the Fund's six-month performance somewhat relative to its Lipper peer average.
The total return for the Lipper Short U.S. Government Fund category was 1.78%
for the six months ended February 28, 1999. However, we believe active
management of duration and of our Treasury and mortgage-backed security holdings
should benefit the Fund over the longer term.

(1) SEC yields reflect the portfolio's earning power net of expenses, expressed
as an annualized percentage of the public offering price per share. If the
Advisor or its affiliates had not borne certain expenses, the yields would have
been lower; 3.84% for Class A, 3.30% for Class B and 3.76% for Class C.

Class B and C share (newer class shares) performance includes returns of the
Fund's Class A shares (oldest existing fund class) for periods prior to the
inception dates of the newer class shares. Class A share returns have not been
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
Class A shares and the newer class shares. Had the expense differential been
reflected, the returns for periods prior to the inception date of the newer
class shares would have been lower.

The Lehman Brothers Government Bond (1-3 Year) Index is an unmanaged index that
tracks the performance of short-term U.S. government securities. Unlike mutual
funds, indexes are not investments and do not incur fees or charges. It is not
possible to invest directly in an index. The Lipper Short U.S. Government Fund
Average represents a hypothetical investment in the funds that comprise the
Lipper Short U.S. Government Fund Category.

Past performance cannot predict future results.

COLONIAL INTERMEDIATE U.S. GOVERNMENT FUND

THE FUND MAINTAINS A CONSERVATIVE PORTFOLIO INVESTED PRIMARILY IN U.S.
GOVERNMENT SECURITIES, WITH A RISK PROFILE SIMILAR TO A FIVE-YEAR TREASURY. THE
FUND IS MANAGED TO MAINTAIN AN AVERAGE DURATION OF BETWEEN 2.5 AND 5.5 YEARS.

Declining interest rates and increasing fears of prepayments early in the period
led us to reduce our exposure to mortgage-backed securities. However, as rates
moved up again in early 1999, we purchased mortgage securities, as they became
more attractive relative to other sectors of the portfolio. We increased our
exposure in mortgage securities from 60% to 87% and decreased the percentage of
assets in Treasurys (especially those with an intermediate duration).

Furthermore, we lengthened the portfolio's duration from 4.7 years to 5.4 years
at the end of the period. This shift allowed the portfolio to take advantage of
higher interest rates and to position the Fund for greater price appreciation
potential.

Our strategy to increase mortgage-backed securities in the portfolio hampered
the Fund's six-month performance somewhat relative to its Lipper peer average.
The total return for the Lipper Intermediate U.S. Government Fund category was
0.76% for the six months ended February 28, 1999. We believe active management
of duration and of our Treasury and mortgage-backed security holdings should
prove beneficial over the long term.

(1) SEC yields reflect the portfolio's earning power net of expenses, expressed
as an annualized percentage of the public offering price per share. If the
Advisor or its affiliates had not waived certain fees, the yield would have been
4.36% for Class C.

Class B, C and Z share (newer class shares) performance includes returns of the
Fund's Class A shares (oldest existing fund class) for periods prior to the
inception dates of the newer class shares. Class A share returns have not been
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
Class A shares and the newer class shares. Had the expense differential been
reflected, the returns for periods prior to the inception date of the newer
class shares would have been lower.

COLONIAL FEDERAL SECURITIES FUND

THE FUND INVESTS PRIMARILY IN U.S. GOVERNMENT SECURITIES AND IS DESIGNED FOR
INVESTORS WHO ARE WILLING TO ACCEPT THE RISKS ASSOCIATED WITH LONGER-TERM
SECURITIES. THE FUND OFFERS THE HIGHEST RETURN POTENTIAL OF COLONIAL'S THREE
GOVERNMENT FUNDS.

During the six-month period, we increased our weighting in mortgage-backed
securities from 61% of net assets to 75%. This increased the mortgage exposure
in the Fund's 30-year holdings and decreased the percentage of assets in
Treasurys. At the same time, we reduced the number of AA-rated, asset-backed
holdings in the portfolio to improve portfolio liquidity and boost credit
quality.

At the end of the period, we lengthened the duration of the Fund from nearly 6
years to 6.6 years to take advantage of higher interest rates and to position
the Fund for greater price appreciation potential.

Our strategy to increase mortgage-backed securities in the portfolio hampered
the Fund's six-month performance somewhat relative to its Lipper peer average.
The total return for the Lipper U.S. Government Fund category was 0.19% for the
six months ended February 28, 1999. As long as economic uncertainty and
volatility exists, we believe active management of duration and of our Treasury
and mortgage-backed security holdings should prove beneficial over the long
term.

(1) SEC yields reflect the portfolio's earning power net of expenses, expressed
as an annualized percentage of the public offering price per share. If the
Advisor or its affiliates had not waived certain fees, the yield would have been
4.85% for Class C.

Class B, C and Z share (newer class shares) performance includes returns of the
Fund's Class A shares (oldest existing fund class) for periods prior to the
inception dates of the newer class shares. Class A share returns have not been
restated to reflect any expense differential (e.g., Rule 12b-1 fees) between
Class A shares and the newer class shares. Had the expense differential been
reflected, the returns for periods prior to the inception date of the newer
class shares would have been lower.

The Lehman Brothers Intermediate Government Bond Index is an unmanaged index
that tracks the performance of U.S. government securities. Unlike mutual funds,
indexes are not investments and do not incur fees or charges. It is not possible
to invest directly in an index. The Lipper U.S. Government Average represents a
hypothetical investment in the funds that comprise the Lipper U.S. Government
Fund Category.

Past performance cannot predict future results.

NOTES TO FINANCIAL STATEMENTS

February 28, 1999 (Unaudited)
NOTE 1: INTERIM FINANCIAL STATEMENTS
In the opinion of management of Colonial Short Duration U.S. Government Fund
(CSDUSGF) and Colonial Intermediate U. S. Government Fund (CIUSGF), both a
series of Colonial Trust II, and Colonial Federal Securities Fund (CFSF), a
series of Colonial Trust III (the series are collectively referred to as the
Funds and are diversified portfolios), the accompanying financial statements
contain all normal and recurring adjustments necessary for the fair presentation
of the financial position of the Funds at February 28, 1999, and the results of
their operations, the changes in their net assets and the financial highlights
for the six months then ended.

NOTE 2: ACCOUNTING POLICIES

ORGANIZATION: The Funds are Massachusetts business trusts registered under the
Investment Company Act of 1940, as amended, as open end management investment
companies. CSDUSGF's investment objective is to seek as high a level of current
income, as is consistent with very low volatility, by investing primarily in
U.S. government securities and maintaining a weighted average portfolio duration
of three years or less. CIUSGF's investment objective is to seek as high a level
of current income and total return, as is consistent with prudent risk, by
investing primarily in U.S. government securities. CFSF's investment objective
is to seek as high a level of current income and total return, as is consistent
with prudent longer-term investing, by investing primarily in U.S. government
securities. The Funds may issue an unlimited number of shares. CSDUSGF offers
three classes of shares: Class A, Class B, and Class C. CIUSGF and CFSF offer
four classes of shares: Class A, Class B, Class C, and Class Z. Class A shares
are sold with a front-end sales charge and a 1.00% contingent deferred sales
charge on redemptions made within eighteen months on an original purchase of $1
million to $5 million. Class B shares are subject to an annual distribution fee
and a contingent deferred sales charge. Class B shares will convert to Class A
shares when they have been outstanding approximately eight years. Class C shares
are subject to a contingent deferred sales charge on redemptions made within one
year after purchase and an annual distribution fee. Effective January 29, 1999
and January 11, 1999, CIUSGF and CFSF, respectively, began offering Class Z
shares. Class Z shares are offered continuously at net asset value. There are
certain restrictions on purchasing Class Z shares, please refer to a prospectus.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amount of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies that are consistently followed in the
preparation of the Funds' financial statements.

SECURITY VALUATION AND TRANSACTIONS: The Funds are valued by a pricing service
based upon market transactions for normal, institutional-size trading units of
similar securities. When management deems it appropriate, an over-the-counter or
exchange bid quotation is used.

Options are valued at the last reported sale price, or in the absence of a sale,
the mean between the last quoted bid and asking price. Short-term obligations
with a maturity of 60 days or less are valued at amortized cost.

Portfolio positions for which market quotations are not readily available are
valued at fair value under procedures approved by the Trustees.

Security transactions are accounted for on the date the securities are
purchased, sold or mature.

Cost is determined and gains (losses) are based upon the specific identification
method for both financial statement and federal income tax purposes.

The Funds may enter into mortgage dollar roll transactions. A mortgage dollar
roll transaction involves a sale by the Fund of securities that it holds with an
agreement by the Fund to repurchase substantially similar securities at an
agreed upon price and date. During the period between the sale and repurchase,
the Fund will not be entitled to accrue interest and receive principal payments
on the securities sold. Mortgage dollar roll transactions involve the risk that
the market value of the securities sold by the Fund may decline below the
repurchase price of those securities. In the event the buyer of the securities
under a mortgage dollar roll transaction files for bankruptcy or becomes
insolvent, the Fund's use of proceeds of the transaction may be restricted
pending a determination by or with respect to the other party.

                                                                              15

================================================================================
February 28, 1999

The Funds may trade securities on other than normal settlement terms. This may
increase the risk if the other party to the transaction fails to deliver and
causes the Fund to invest at less advantageous prices.

The Funds maintain U.S. government securities or other liquid high grade debt
obligations as collateral with respect to mortgage dollar roll transactions and
securities traded on other than normal settlement terms.

DETERMINATION OF CLASS NET ASSET VALUES AND FINANCIAL HIGHLIGHTS: All income,
expenses (other than the Class A, Class B, and Class C service fees and Class B
and Class C distribution fees), and realized and unrealized gains (losses), are
allocated to each class proportionately on a daily basis for purposes of
determining the net asset value of each class.

Class A, Class B, and Class C per share data and ratios are calculated by
adjusting the expense and net investment income ratios for each Fund for the
entire period by the service fees for Class A, Class B, and Class C shares and
the distribution fees for Class B and Class C shares only.

FEDERAL INCOME TAXES: Consistent with each Fund's policy to qualify as a
regulated investment company and to distribute all of its taxable income, no
federal income tax has been accrued.

INTEREST INCOME, FEE INCOME, DEBT DISCOUNT AND PREMIUM: Interest income is
recorded on the accrual basis. Fee income attributable to mortgage dollar roll
transactions is recorded on the accrual basis over the term of the transaction.
Original issue discount is accreted to interest income over the life of a
security with a corresponding increase in the cost basis. For CSDUSGF, market
discount is not accreted and premium is amortized against interest income with a
corresponding decrease in the cost basis. For CSDUSGF, market discount is not
accreted and premium is amortized against interest income with a corresponding
decrease in the cost basis. For CIUSGF and CFSF, premium and market discount are
not amortized or accreted.

DISTRIBUTIONS TO SHAREHOLDERS: Each Fund declares and records distributions
daily and pays monthly.

The amount and character of income and gains to be distributed are determined in
accordance with income tax regulations which may

NOTES CONT.

differ from generally accepted accounting principles. These differences are
primarily due to differing treatments for mortgage backed securities for book
and tax purposes and expired capital loss carryforwards. Permanent book and tax
basis differences will result in reclassifications to capital accounts.

OTHER: The Funds' custodian takes possession through the federal book entry
system of securities collateralizing repurchase agreements. Collateral is
marked-to-market daily to ensure that the market value of the underlying assets
remains sufficient to protect the Fund. The Fund may experience costs and delays
in liquidating the collateral if the issuer defaults or enters bankruptcy.

NOTES CONT.

Class C shares. CIUSGF and CFSF each pay a distribution fee equal to 0.75%
annually of the average net assets attributable to Class B and Class C shares.
The Distributor has voluntarily agreed, until further notice, to waive a portion
of the Class C share distribution fee so that it does not exceed 0.60% annually.

The CDSC and the fees received from the 12b-1 plan are used principally as
repayment to the Distributor for amounts paid by the Distributor to dealers who
sold such shares.

EXPENSE LIMITS: For CSDUSGF, the Advisor has agreed, until further notice, to
waive fees and bear certain Fund expenses to the extent that total expenses
(exclusive of service and distribution fees, brokerage commissions, interest,
taxes and extraordinary expenses, if any) exceed 0.60% annually of the Fund's
average net assets. Through December 31, 1997, the expense limit was 0.30%
annually of the Fund's average net assets.

OTHER: The Funds pay no compensation to their officers, all of whom are
employees of the Advisor. 

The Funds' Trustees may participate in a deferred compensation plan which may be
terminated at any time. Obligations of the plan will be paid solely out of the
Fund's assets.

CAPITAL LOSS CARRYFORWARDS: At August 31, 1998, capital loss carryforwards
available (to the extent provided in regulations) to offset future realized
gains were approximately as follows:

                      Year of      Capital loss

Of the CIUSGF loss carryforwards expiring in 2001 and 2002, $12,601,000 and
$4,423,000, respectively, were acquired in the merger with Liberty Financial
U.S. Government Securities Fund. Their availability for use in offsetting any
future realized gains may be limited in a given year.

                                   ------------

Expired capital loss carryforwards, if any, are recorded as a reduction of
capital paid in.

To the extent loss carryforwards are used to offset any future realized gains,
it is unlikely that such gains would be distributed since they may be taxable to
shareholders as ordinary income.

OTHER: CIUSGF and CFSF may purchase or sell futures contracts and purchase and
write options on futures and securities. The Funds will use these instruments to
hedge against the effects of changes in the value of the portfolio securities
due to anticipated

NOTES CONT.

changes in interest rates and/or market conditions and not for trading purposes.
The Funds may also invest in these instruments for duration management. The use
of futures contracts and options involves certain risks which include (1) the
imperfect correlation between the price movement of the instruments and the
underlying securities, (2) inability to close out a position due to different
trading hours, or the absence of a liquid market for either the instrument or
the underlying securities or (3) an inaccurate prediction by the Advisor of the
future direction of interest rates. Any of these risks may involve amounts
exceeding the variation margin, or option premium recorded in the Funds'
Statement of Assets and Liabilities at any given time.

NOTE 5: LINE OF CREDIT

CSDUSGF may borrow up to 33 1/3% of its net assets under a line of credit for
temporary or emergency purposes. Any borrowings bear interest at one of the
following options determined at the inception of the loan: (1) federal funds
rate plus 1/2 of 1%, (2) the lending bank's base rate or (3) LIBOR offshore loan
rate plus 1/2 of 1%. There were no borrowings under the line of credit during
the six months ended February 28, 1999.
