AMERICAN MUNICIPAL TERM TRUSTS
- --------------------------------------------------------------------------------

PRIMARY INVESTMENTS
High-quality municipal obligations including municipal zero-coupon securities.

FUND OBJECTIVE
American Municipal Term Trust (AXT), American Municipal Term Trust II (BXT), and
American Municipal Term Trust III (CXT) are diversified, closed-end investment
management companies. The investment objectives of AXT, BXT and CXT are to
provide high current income exempt from regular federal income tax and to return
$10 per share on or shortly before April 15, 2001; April 15, 2002; and April 15,
2003, respectively - although each fund's termination may be extended up to five
years if necessary to assist the fund in reaching its $10 per share objective.
The funds' income may be subject to state or local tax and the federal
alternative minimum tax. Investors should consult their tax advisers. As with
other investment companies, there can be no assurance that each fund will
achieve its objective.

All total return figures are through June 30, 1997, and reflect the reinvestment
of distributions but not sales charges. NAV-based performance is used to measure
investment management results. At the end of June, the six-month NAV total
returns for AXT, BXT and CXT were 2.12%, 2.73% and 3.69%, respectively.  As
noted in our last shareholder report to you, we no longer compare the funds' NAV
performance to a market benchmark. This is because our primary goal is to meet
the funds' investment objectives of providing high current income exempt from
regular federal income tax and returning $10 per share to investors at the
funds' termination dates.

Based on market price, the six-month total returns for AXT, BXT and CXT were
1.84%, 4.10% and 5.24%, respectively. Average annualized total return figures
based on the change in market price for the one-year, five-year and since
inception periods ended June 30, 1997, were 10.31%, 7.30% and 8.09% for AXT and
10.05%, 7.69% and 7.64% for BXT. The one-year and since inception figures were
13.74% and 7.17% for CXT.

PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THESE INVESTMENTS. NEITHER SAFETY OF
PRINCIPAL NOR STABILITY OF INCOME IS GUARANTEED. Past performance does not
guarantee future results. The investment return and principal value of an
investment will fluctuate so that fund shares, when sold, may be worth more or
less than their original cost. Closed-end funds, such as these funds, often
trade at discounts to net asset value. Therefore, you may be unable to realize
the full net asset value of your shares when you sell.

DEAR SHAREHOLDERS:

FOR THE SIX-MONTH PERIOD ENDED JUNE 30, 1997, WE ARE PLEASED TO REPORT THAT THE
AMERICAN MUNICIPAL TERM TRUSTS (AXT, BXT AND CXT) REMAINED ON TARGET TO MEET
THEIR INVESTMENT OBJECTIVES. The funds continued to earn more than their monthly
common and preferred stock*** dividends and add to their dividend reserves. This
enabled the funds to maintain their monthly common stock distributions of 5.42
cents, 5.17 cents and 4.75 cents, respectively, which have been unchanged since
their inceptions. In addition, net asset values for the funds remained above the
$10 per share objective. As of June 30, 1997, the net asset values for AXT, 
BXT and CXT were $11.49, $11.48 and $11.08, respectively. (Please refer to the
charts below and on page 4 for each fund's distribution and net asset value
history since inception.)

DURING THE FIRST SIX MONTHS OF 1997, INTEREST RATES AND, IN TURN, BOND PRICES
WERE VOLATILE. The economy showed signs of strength early in the period,
prompting the Federal Reserve (the Fed) to raise the federal funds rate*** in
March from 5.25% to 5.50%. That caused bond yields to rise and prices to fall.
It was the first time in more than two years that the Fed had adopted a
tightening monetary policy. Beginning in mid-April, however, concerns of

an overheating economy were replaced by signs that the economy was beginning to
slow and inflation was decelerating. As a result, interest rates trended
downward and bond prices increased in the final three months.

FOR THE PERIOD, TAX-EXEMPT BONDS OUTPERFORMED THEIR TAXABLE COUNTERPARTS. The
prices of 30-year, AAA-rated municipal bonds ended the period basically
unchanged, compared to a decrease in the prices of 30-year Treasuries.
Municipals outperformed mainly because of a decrease in the supply of new issues
and, to a lesser degree, because of a pickup in demand. In our report to you six
months ago, we were anticipating an increase in the supply of new national
municipal bonds in 1997. However, year-to-date new issues are down 2.5% compared
to 1996. 

DURING THE PERIOD, WE CONTINUED TO REDUCE OUR EXPOSURE TO LONGER MATURITY BONDS
AND INCREASE OUR POSITION IN BONDS THAT COME DUE CLOSER TO THE FUNDS'
TERMINATION DATES. (See chart below.) This strategy is designed to help achieve
the funds' objective of returning $10 per share at maturity. The closer a bond's
maturity date*** is to the termination date of the fund, the less sensitive the
bond's price will be to interest rate changes and the more certain we can be of
its value at termination. This strategy slightly lowered income, but as noted
earlier, the funds earned more than their monthly common and preferred stock
dividends and added to their dividend reserves. (See each fund's dividend
reserve amount in the chart on page 4.) 


BONDS MATURING WITHIN A YEAR OF TERMINATION

The chart below illustrates the percentage of bonds in each fund with maturity
dates within a year of the funds' termination dates.

PORTFOLIO MANAGERS' LETTER (CONTINUED)

GIVEN THE RECENT DECLINE IN INTEREST RATES, WE ARE NOT CURRENTLY IMPLEMENTING
OUR STRATEGY OF SELLING LONGER MATURITY BONDS TO PURCHASE SHORTER MATURITY
BONDS. Lower rates have increased the prices of the longer maturity bonds in the
funds, creating the potential for additional taxable capital gains distributions
if the funds sell these bonds. Moreover, lower rates have reduced the income
available from shorter maturity bonds in which the fund would invest. This
strategy, however, has been effective in the past, and we do plan to employ it
again in the appropriate economic environment.

AS THE FUNDS APPROACH THEIR TERMINATIONS, WE EXPECT THEIR NET ASSET VALUES TO
DECLINE DUE TO THREE FACTORS. First, at some point we will continue to sell
longer maturity bonds in favor of bonds with lower coupons*** that come due
closer to the funds' termination dates. If these shorter-maturity bonds pay
insufficient income to maintain our current dividends, the funds' dividend
reserves may be used to pay common and/or preferred dividends. Second, part of
the unrealized appreciation in the funds is the result of bonds that are
currently trading at unrealized gains.*** As the maturity and/or refunding
dates*** of these bonds approach, their market

prices will converge toward a price that is at or near par.*** Third, any
realized gains*** in the funds will have to be paid out before or at
termination. All three of these factors could reduce the funds' net asset
values. In addition, keep in mind that the funds are always subject to interest
rate risk*** and credit risk,*** which could have an impact on net asset value.
Please refer to the chart on page 4 for each fund's current dividend reserve,
unrealized appreciation and accumulated realized gains.

LOOKING AHEAD, WE REMAIN POSITIVE ABOUT THE TAX-EXEMPT MARKET. The economy
appears to be growing at a moderate pace, which should help keep inflation under
control. Given this scenario, the Fed is not likely to raise interest rates.
However, we believe the Fed will continue to be vigilant about controlling
economic growth and inflation and may increase short-term interest rates 
if inflation becomes a major concern. Should interest rates rise, we would again
look to trade longer maturity bonds for shorter maturities while attempting to
keep the impact on each fund's income-producing potential to a minimum.

AS ALWAYS, WE WILL CONTINUE TO APPLY OUR PROPRIETARY CREDIT ANALYSIS TO EXISTING
HOLDINGS AND NEW PURCHASES as we work toward meeting the funds' objectives. Our
credit analysis is designed to help ensure that the municipalities in which we
invest meet our high-quality criteria and remain able to repay interest and
principal in a timely manner.

Thank you for your investment in the American Municipal Term Trusts. We remain
committed to providing you with quality service and look forward to helping you
achieve your financial goals.

Sincerely,


/s/ Douglas J. White                    /s/ Ronald R. Reuss

(1) ORGANIZATION
 ................................
               American Municipal Term Trust Inc. (AXT), American Municipal Term
               Trust Inc. II (BXT) and American Municipal Term Trust Inc. III
               (CXT) (the funds) are registered under the Investment Company Act
               of 1940 (as amended) as diversified, closed-end management
               investment companies. AXT, BXT and CXT expect to terminate
               operations and distribute all of their net assets to shareholders
               on or shortly before April 15, 2001, April 15, 2002, and April
               15, 2003, respectively, although termination may be extended to a
               date no later than April 15, 2006, April 15, 2007, and April 15,
               2008, respectively. The funds invest primarily in high-quality
               municipal obligations including municipal zero-coupon securities.
               Fund shares are listed on the New York Stock Exchange under the
               symbols AXT, BXT and CXT, respectively.
 
(2) SUMMARY OF
    SIGNIFICANT
    ACCOUNTING
    POLICIES
 ................................
                  INVESTMENTS IN SECURITIES
               Portfolio securities for which market quotations are readily
               available are valued at current market value. If market
               quotations or valuations are not available, or if Piper Capital
               Management Incorporated believes such quotations or valuations
               are inaccurate, unreliable or not reflective of market value,
               portfolio securities are valued according to procedures adopted
               by the funds' board of directors in good faith at "fair value",
               that is, a price that the funds might reasonably expect to
               receive for the security or other asset upon its current sale.
 
               The current market value of certain fixed income securities is
               provided by an independent pricing service. Fixed income
               securities for which prices are not available from an independent
               pricing service but where an active market exists are valued
               using market quotations obtained from one or more dealers that
               make markets in the securities or from a widely-used quotation
               system. Short-term securities with maturities of 60 days or less
               are valued at amortized cost, which approximates market value.

               Securities transactions are accounted for on the date securities
               are purchased or sold. Realized gains and losses are calculated
               on the identified-cost basis. Interest income, including
               amortization of bond discount and premium, is recorded on an
               accrual basis.
 
                  SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
               Delivery and payment for securities that have been purchased by
               the funds on a when-issued or forward-commitment basis can take
               place a month or more after the transaction date. During this
               period, such securities do not earn interest, are subject to
               market fluctuation and may increase or decrease in value prior to
               their delivery. The funds segregate, with their custodian, assets
               with a market value equal to the amount of their purchase
               commitments. The purchase of securities on a when-issued or
               forward-commitment basis may increase the volatility of the
               funds' net asset value if the funds make such purchases while
               remaining substantially fully invested. As of June 30, 1997,
               American Municipal Term Trust Inc., American Municipal Term Trust
               Inc. II, and American Municipal Term Trust Inc. III had entered
               into outstanding when-issued or forward commitments of
               $1,005,830, $1,241,879 and $0, respectively.
 
                  FEDERAL TAXES
               Each fund is treated separately for federal income tax purposes.
               Each fund intends to comply with the requirements of the Internal
               Revenue Code applicable to regulated investment companies and not
               be subject to federal income tax. Therefore, no income tax
               provision is required. The funds intend to distribute their
               taxable net investment income and realized gains, if any, to
               avoid the payment of any federal excise taxes.
 
               Net investment income and net realized gains (losses) may differ
               for financial statement and tax purposes primarily because of
               market discount amortization. The character of distributions made
               during the year from net investment income or net realized gains
               may differ from its ultimate characterization for federal income
               tax

               purposes. In addition, due to the timing of dividend
               distributions, the fiscal year in which amounts are distributed
               may differ from the year that the income or realized gains
               (losses) were recorded by the funds.
 
                  DISTRIBUTIONS TO SHAREHOLDERS
               Distributions from net investment income are made monthly for
               common shareholders and weekly for preferred shareholders. Common
               stock distributions are recorded as of the close of business on
               the ex-dividend date and preferred stock dividends are accrued
               daily. Net realized gains distributions, if any, will be made at
               least annually. Distributions are payable in cash or, for common
               shareholders pursuant to the funds' dividend reinvestment plans,
               reinvested in additional shares of the funds' common stock. Under
               the plans, common shares will be purchased in the open market.
 
                  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
               in the financial statements. Actual results could differ from
               these estimates.
 
(3) REMARKETED
    PREFERRED
    STOCK
 ................................
               American Municipal Term Trust, American Municipal Term Trust II,
               and American Municipal Term Trust III have issued and, as of June
               30, 1997, have outstanding 1,700 shares, 1,480 shares, and 1,064
               shares, respectively, of remarketed preferred stock (RP) with a
               liquidation preference of $25,000 per share for each fund. The
               dividend rate on the RP is adjusted every seven days as
               determined by the remarketing agent. On June 30, 1997, the
               dividend rates were 4.05%, 3.90% and 4.00% for American Municipal
               Term Trust, American Municipal Term Trust II, and American
               Municipal Term Trust III, respectively.
 
               RP is a registered trademark of Merrill Lynch & Company.

               monthly investment management fee in an amount equal to an
               annualized rate of 0.25% of the funds' average weekly net assets
               (computed by subtracting liabilities, which exclude preferred
               stock, from the value of the total assets of the funds). For its
               fee, the adviser provides investment advice and, in general,
               conducts the management and investment activity of the funds.
 
               The administration agreement provides the administrator with a

               the funds' average weekly net assets (computed by subtracting
               liabilities, which exclude preferred stock, from the value of the
               total assets of the funds). For its fee, the administrator will
               provide regulatory, reporting, and record-keeping services for
               the funds.

               The funds have entered into a remarketing agent agreement with

               monthly fee in an amount equal to an annualized rate of 0.25% of
               the funds' average amount of RP outstanding. For its fee, the
               remarketing agent will remarket shares of RP tendered to it, on
               behalf of shareholders thereof, and will determine the applicable
               dividend rate for each seven-day dividend period.

GLOSSARY OF TERMS***
- --------------------------------------------------------------------------------

COUPON
The interest rate on a bond that the issuer promises to pay to the holder until
the bond matures or resets its rate. It is expressed as an annual percentage of
face value.

CREDIT RISK
The risk that a bond issuer will not make timely principal and interest payments
and a loss to the investor will result.

FEDERAL FUNDS RATE
The federal funds rate is the interest rate charged by banks with excess
reserves at a Federal Reserve district bank to banks needing overnight loans to
meet reserve requirements. The federal funds rate is the most sensitive
indicator of the direction of interest rates, since it is set daily by the
market, unlike the prime rate and the discount rate, which are periodically
changed by banks and by the Federal Reserve Board, respectively.

INTEREST RATE RISK
The risk that after an investor purchases a bond, interest rates will rise and
the price of the bond will go down.

MATURITY DATE
The date on which the principal amount of a bond is due and payable to the
investor.

PAR 
The dollar amount of a bond at the time it was issued and the amount that will
be repaid at maturity.

PREFERRED STOCK
Preferred stock pays dividends at a specified rate and has preference over
common stock in the payments of dividends and the liquidation of assets. Rates
paid on preferred stock are reset every seven days and are based on short-term,
tax-exempt interest rates. Preferred shareholders accept these short-term rates
in exchange for low credit risk (shares of preferred stock are rated AAA by
Moody's and S&P) and high liquidity (shares of preferred stock trade at par and
are remarketed every seven days). The proceeds from the sale of preferred stock
are invested at intermediate- and long-term tax-exempt rates. Because these
intermediate- and long-term rates are normally higher than the short-term rates
paid on preferred stock, common shareholders benefit by receiving higher
dividends and/or an increase to the dividend reserve. However, the risk of
having preferred stock is that if short-term rates rise higher than
intermediate- and long-term rates, creating an inverted yield curve, common
shareholders may receive a lower rate of return than if their fund did not have
any preferred stock outstanding. This type of economic environment is unusual
and historically has been short term in nature. Investors should also be aware
that the issuance of preferred stock results in the leveraging of common stock,
which increases the volatility of both the net asset value of the fund and the
market value of shares of common stock.

GLOSSARY OF TERMS (CONTINUED)

REFUNDING DATE
The specific date when a bond is redeemed before maturity.

REALIZED GAINS
Profits earned by a fund from the sale of a security at a market price that is
higher than its cost basis.

UNREALIZED GAINS
A bond is said to be trading at unrealized gains when its current market price
is higher than its cost basis.
