                                                          Two World Trade Center
LETTER TO SHAREHOLDERS July 31, 1999                    New York, New York 10048

DEAR SHAREHOLDER:

The six-month period ended July 31, 1999 has been a difficult one for the
high-yield bond market. Calendar year 1999 began with the high yield market
still feeling the effects of the dramatic flight to quality that occurred during
the second half of 1998. In response to concerns about the rapidly escalating
foreign-market crisis and its potential effect on the U.S. economy, investors
sought the relative safety of U.S. government securities over more economically
sensitive investments such as equities and high-yield bonds. This action
resulted in a sharp correction in the high-yield bond market during the second
half of 1998. High-yield bond prices declined as much as 15 percent and yields
rose from approximately 9 percent to the 12-percent range. The high-yield market
also experienced its own flight to quality during late 1998, with the middle
tier of the market (B-rated issues) significantly underperforming the upper tier
(BB-rated issues), due to investors' severe risk aversion.

As we enter the second half of 1999, the high-yield market has yet to rebound
from its woes of late last year. Fears about the foreign-market crisis have now
been replaced by concerns over potential inflation and ongoing credit-tightening
actions by the Federal Reserve Board. These concerns drove interest rates
sharply higher during the first half of 1999, resulting in a very weak
fixed-income market environment. While the high-yield market held up better than
most other fixed-income markets during the first half of 1999, it clearly
remains quite weak, due to the depressed bond market environment that exists
today. As a result, as we enter the second half of 1999, high-yield market
yields are approaching their highest and most attractive levels since the early
1990s, providing an unusually high yield advantage over U.S. Treasuries.

PERFORMANCE

For the six-month period ended July 31, 1999, Morgan Stanley Dean Witter High
Income Advantage Trust III declined 1.74 percent, based on a change in net asset
value (NAV) and reinvestment of distributions. Based on a change in the Trust's
market price on the New York Stock Exchange (NYSE) and reinvestment of
distributions, the Trust's total return for the six-month period was 8.55
percent.

Over the past six months, the Trust continued to distribute regular monthly
income dividends, at a rate of $0.06 per share. For the six-month period ended
July 31, 1999, the Trust's distributions totaled $0.36 per share. On July 31,
1999, the Trust had net assets in excess of $59 million.

PORTFOLIO STRATEGY

During the fiscal year, the Trust maintained a position in the more defensive,
higher-quality end of the high-yield market, which held up well in the period's
recent volatile environment. Despite these defensive holdings, however, the
Trust's more significant, long-term core position in the B-rated sector of the
market was sharply affected by the recent market correction, as bond prices
declined sharply and yields rose dramatically. In terms of investment strategy,
we continue to concentrate on industry sectors that have historically proven to
be more predictable, recession resistant and/or growth oriented, such as cable
television, cellular communications, food and beverages, media, supermarkets and
telecommunications. We believe that these industry groups are poised to perform
well over the next year. We also expect to see continued consolidation and
merger activity within these industries, which should result in improved credit
quality for many of the industry's players. We continue to focus primarily on
domestic companies, given the favorable outlook for continued growth in the U.S.
economy, and are avoiding the emerging foreign high-yield markets at this time,
because of the higher degree of uncertainty and volatility associated with many
of these markets over the past few years.

We would like to remind you that the Trustees have approved a procedure whereby
the Trust may, when appropriate, repurchase shares in the open market or in
privately negotiated transactions at a price not above market value or net asset
value, whichever is lowest at the time of purchase.

MORGAN STANLEY DEAN WITTER HIGH INCOME ADVANTAGE TRUST III

NOTES TO FINANCIAL STATEMENTS July 31, 1999 (unaudited)

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Dean Witter High Income Advantage Trust III (the "Trust"), is
registered under the Investment Company Act of 1940, as amended, as a
diversified, closed-end management investment company. The Trust's primary
investment objective is to earn a high level of current income and, as a
secondary objective, capital appreciation, but only when consistent with its
primary objective. The Trust seeks to achieve its objective by investing
primarily in lower-rated fixed income securities. The Trust was organized as a
Massachusetts business trust on November 23, 1988 and commenced operations on
February 28, 1989.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS -- (1) an equity security listed or traded on the
New York, American or other domestic or foreign stock exchange is valued at its
latest sale price on that exchange prior to the time when assets are valued; if
there were no sales that day, the security is valued at the latest bid price (in
cases where securities are traded on more than one exchange; the securities are
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Morgan Stanley Dean Witter Advisors Inc. (the "Investment
Manager") that sale or bid prices are not reflective of a security's market
value, portfolio securities are valued at their fair value as determined in good
faith under procedures established by and under the general supervision of the
Trustees; (4) certain of the Trust's portfolio securities may be valued by an
outside pricing service approved by the Trustees. The pricing service may
utilize a matrix system incorporating security quality, maturity and coupon as
the evaluation model parameters, and/or research and evaluations by its staff,
including review of broker-dealer market price quotations, if available, in
determining what it believes is the fair valuation of the portfolio securities
valued by such pricing service; and (5) short-term debt securities having a
maturity date of more than sixty days at time of purchase are valued on a
mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day.

NOTES TO FINANCIAL STATEMENTS July 31, 1999 (unaudited), continued

Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily except where collection is not expected.

C. FEDERAL INCOME TAX STATUS -- It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Trust records dividends
and distributions to its shareholders on the record date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.

2. INVESTMENT MANAGEMENT AGREEMENT

Pursuant to an Investment Management Agreement, the Trust pays the Investment
Manager a management fee, calculated weekly and payable monthly, by applying the

assets exceeding $250 million but not exceeding $500 million; 0.50% to the
portion of weekly net assets exceeding $500 million but not exceeding $750
million; 0.40% to the portion of weekly net assets exceeding $750 million but
not exceeding $1 billion; and 0.30% to the portion of weekly net assets

records and furnishes, at its own expense, office
