AT VANGUARD WE BELIEVE THAT TRADITION MATTERS

Our 8,000 crew members embrace the traditional values on which our success is
built, including integrity, hard work, thrift, teamwork, and fair dealing on
behalf of our clients.

Our report cover pays homage to three anniversaries, each of great significance
to The Vanguard Group:

- -  The 200th anniversary of the Battle of the Nile, which commenced on August 1,
   1798. HMS Vanguard, the victorious British flagship at the Nile, is our
   namesake. And its motto-- "Leading the way"--serves as a guiding principle
   for our company.

- -  The 100th birthday, on July 23, 1998, of Walter L. Morgan, founder of
   Wellington Fund, the oldest member of what became The Vanguard Group. Mr.
   Morgan was friend and mentor to Vanguard founder John C. Bogle, and helped to
   shape the standards and business principles that Mr. Bogle laid down for
   Vanguard at its beginning nearly 25 years ago: a stress on balanced,
   diversified investments; insistence on fair dealing and candor with clients;
   and a focus on long-term investing. To our great regret, Mr. Morgan died on
   September 2, 1998.

- -  The 70th anniversary, on December 28, 1998, of the incorporation of Vanguard
   Wellington Fund. It is the nation's oldest balanced mutual fund, and one of
   only a handful of funds created in the 1920s that are still in operation.

Although Vanguard constantly tackles new challenges, adopts new technology, and
develops new services, we treasure the traditions and values that set us apart
in a crowded, competitive industry. And we salute our shareholders, whose
support and trust we strive to earn each and every day.

An upward trend in interest rates pulled municipal bond prices down a bit,
partially offsetting the returns from tax-exempt interest income for the seven
Vanguard Municipal Bond Funds during the first half of the 1999 fiscal year.
Returns, if modest during this short period, remained positive, ranging from
+1.5% for the Tax-Exempt Money Market and Short-Term Tax-Exempt Funds to +2.0%
for the Insured Long-Term and High-Yield Tax-Exempt Funds.

       The table below shows the six-month total return (capital change plus
reinvested dividends) for each fund, along with a breakdown of its capital and
income components. For each of these funds, the income dividends distributed by
the fund are generally free from federal income taxes. The table also shows each
fund's annualized yield as of April 30. Per-share figures for each fund,
including income dividends and any distributions from net realized capital
gains, along with net asset values, are presented in the table following this
letter. The returns of each fund in comparison with its index benchmark are
shown in the Performance Summaries on pages 8 through 11. Each fund tracked its
index closely--within 0.4 percentage point--during the first six months of the
fiscal year.

**An investment in a money market fund is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency. Although
the fund seeks to preserve the value of your investment at $1 per share, it is
possible to lose money by investing in the fund.

       It's important to note that semiannual returns for bond funds account for
only half of the year's interest income, while price changes occur immediately
in response to changes in interest rates. Over the long run, however, interest
income accounts for the vast majority of the total return of a bond fund. For
this reason, we think it's useful to present a full year's interest income. The
table on page 2 presents each fund's return for the past twelve months, divided
into its income and capital components.

THE PERIOD IN REVIEW

The economic picture brightened considerably during the six months ended April
30, as the U.S. economy steamed ahead and many countries around the world showed
signs of recovery from financial turmoil. For stocks, this news was good--the
Standard & Poor's 500 Composite Stock Price Index earned a six-month return of
+22.3%. For the bond market, the strength of the economy's expansion raised
fears that inflation, the bond investor's mortal enemy, would reawaken.

</TABLE>

       The U.S. economy expanded at a 6.0% annual pace during the final three
months of 1998 and then recorded a growth rate of 4.1% in the January-March
period. Growth continues to be driven by consumers, who are spending at a record
pace. The boost from the consumer sector has more than offset the drag of a
ballooning trade deficit. A strong job market and low inflation also contributed
to the rosy economic scenario. Unemployment hovered near a 30-year low of 4.2%
of the workforce, while consumer prices rose 1.3% during the period.

       Though there was little concrete evidence of a resurgence of inflation,
the potential for higher prices troubled the bond market during the latter part
of the half-year. The yield of the benchmark 30-year U.S. Treasury bond ended
the period at 5.66%, 50 basis points (0.50 percentage point) higher than its
5.16% yield on October 31, 1998. Long-term Treasury bonds, as measured by the
Lehman Brothers Long U.S. Treasury Bond Index, had a negative return of -3.6%,
as a price decline of -6.6% more than offset the index's +3.0 return from
interest income. At the shorter end of the fixed-income spectrum, rates rose,
though not quite so significantly. The yield of 3-month U.S. Treasury bills was
4.54% on April 30, a bit higher than its 4.32% level at the half-year's start.

       The rise in rates was also more muted in the tax-exempt bond market.
Yields on high-grade, long-term tax-exempt bonds rose just 15 basis points on
balance to 5.28% from 5.13% last October. Yields on high-quality short-term
municipal securities started the period at 2.88% and ended it at 3.17%, up 29
basis points. For a taxpayer in the highest federal income tax bracket, a 5.28%
tax-exempt yield is equivalent to 8.74% on taxable bonds, a highly attractive
proposition for many fixed-income investors.

PERFORMANCE OVERVIEW

Six of our seven funds provided a higher total return for the six months than
the average fund holding tax-exempt securities of similar quality and maturity,
as reflected in the table below. The Short-Term Tax-Exempt Fund, after adjusting
for the shorter maturity range of its holdings compared with those of other
funds in its category, fell short by only 0.1 percentage point. All of the funds
earned more than the inflation rate--consumer prices rose 1.3% during the six
months.

two years as of March 31, 1999.

       Our adviser, Vanguard Fixed Income Group, achieved these excellent
results while maintaining a higher overall credit quality than our peer funds.
We consider high credit quality an important protection for our shareholders in
case the economy sours and diminishes the ability of bond issuers to meet their
obligations. This performance is possible primarily because of our significant
cost advantage over similar



                                       2

funds. The expense ratios (annualized expenses as a percentage of average net
assets) of the Vanguard tax-exempt funds amounted to about 0.20%. Average
expense ratios of competing funds range from about 0.69% for tax-exempt money
market funds to 1.16% for high-yield tax-exempt funds. Competitors must overcome
this significant gap just to hold even with our funds. In essence, low operating
costs provide a valuable head start in our quest to surpass the results of
similar funds. Our Fixed Income Group performed admirably in deploying this cost
advantage to the benefit of the shareholders.

IN SUMMARY

While the environment for municipal bonds was not ideal during the first half of
fiscal 1999, returns were positive. As we have emphasized in the past, and
certainly will in the future, we are convinced that creating a suitable mix of
stock funds, fixed-income funds, and money market funds--and then sticking with
it through good times and bad--is the surest route to long-term investment
success.

       We look forward to reporting to you on the full fiscal year six months
hence.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED APRIL 30, 1999

[PHOTO]

Global stock markets chalked up solid gains during the six months ended April
30, 1999, aided by the efforts of central banks around the world to ease
monetary policy and lower short-term interest rates.

       The remarkably strong U.S. economy helped out by playing locomotive for
the world's economies, soaking up record volumes of imported goods. Indeed, the
United States was the only major nation whose policymakers and bondholders had
to ponder whether growth was too rapid. Concern about a potential surge in
inflation was one reason that interest rates rose modestly and bond prices
generally slipped in the United States.

U.S. STOCK MARKETS

Stock prices soared during the half-year, reflecting both the domestic economy's
strength and the investing public's confidence in future growth of the economy
and corporate profits. The overall market, as measured by the Wilshire 5000
Equity Index, rose 22.8% during the six months ended April 30, while the S&P 500
Index, a proxy for large-capitalization stocks, gained 22.3%.

       The midsummer shock of 1998--when the overall stock market fell by more
than 20%--seemed to be quickly forgotten by investors. Most apparently
overlooked the fact that corporate earnings were flat to slightly lower,
focusing instead on the potential for future earnings. Investors' confidence was
bolstered by the market's quick rebound from its summer stumble and by a general
easing of monetary policy by the world's central banks. The Federal Reserve
Board made three separate quarter-percentage-point reductions in short-term
interest rates during autumn 1998. Central banks in Europe, Asia, and Latin
America also cut rates. These actions lessened fears that the major economies
would be dragged down by the lingering effects of the economic crisis that
struck emerging markets beginning in mid-1997.

*Annualized.

       U.S. consumers demonstrated their confidence in economic conditions by
spending freely, boosting sales of cars, houses, and goods in stores. And why
shouldn't they have been happy? U.S. gross domestic product grew by an annual
rate of 4.1% in the first three months of 1999, and the nation's unemployment
rate closed the period at 4.3%.

       Improved prospects for global growth were a key factor in the continuing
advance of technology stocks (up nearly 42% for the six months) and the
resurgence of some value-stock sectors, such as materials & processing (up 27%)

companies rose 22%; "other energy" stocks gained 23%). Retailers and other
companies in the consumer-discretionary sector gained 34%, reflecting the
strength of consumer spending. Not all consumer-related stocks benefited,
however. Consumer-staples companies, locked in tough price competition and still
feeling the effects of falling profits from overseas operations, were the
worst-performing group in the half-year, down 3%.

U.S. BOND MARKETS

For bond investors, the powerful economic expansion evident during the
November-April period was too much of a good thing. Economists confessed to
puzzlement that the expansion was not triggering an acceleration in wages or
consumer prices. But with oil prices rising, U.S. economic growth expanding at a
4.1% annual pace, and unemployment at 4.3% of the labor force, the lowest point
since February 1970, bond market participants figured that inflation was bound
to accelerate eventually. (This view gained credence shortly after the period's
end, when the Consumer Price Index was reported to have risen 0.7% in April, the
biggest monthly increase in eight years.)

       Despite the Fed's actions to cut short-term interest rates, yields on
U.S. Treasury issues increased over the six months by one-half to three-quarters
of a percentage point. The yield of the 30-year Treasury bond rose 50 basis
points, to 5.66% on April 30 from 5.16% six months earlier. The yield of the
10-year Treasury rose to 5.35% from 4.61%. Very short-term rates didn't rise as
far: Yields on 3-month T-bills rose 22 basis points to 4.54% on April 30. Bond
prices, which move in the opposite direction from interest rates, fell. The
Lehman Brothers Aggregate Bond Index, a benchmark for investment-grade taxable
bonds, earned just 0.7%, as falling prices offset most of the index's 3.0%
interest income for the six-month period.

       Municipal bonds suffered only slight price declines and outperformed
Treasury securities--a turnaround from the previous six months, when Treasuries
were bid up by investors seeking a safe haven during the summer 1998 market
turmoil.

       Not all bond prices fell during the half-year. For high-yield issues, the
strong economy was a tonic. These bonds had suffered considerably during the
market turmoil of summer 1998, as investors feared a global economic downturn
would result in higher defaults by weaker companies. But when economic growth
turned out to be stronger than expected, high-yield bond prices rebounded,
augmenting the bonds' interest income. The Lehman High Yield Index returned 8.3%
during the half-year.

INTERNATIONAL STOCK MARKETS

Overseas stock markets posted gains during the period, despite lingering
economic weakness in Asia and sluggish growth in most of Europe's developed
economies. Crises in some key developing markets, including those of Brazil and
Russia, appeared to be easing as the semiannual period drew to a close. Overall,
the developed markets outside the United States gained 15.4% in U.S.-dollar
terms, as measured by the Morgan Stanley Capital International Europe,
Australasia, Far East (EAFE) Index. Stocks in Europe and Asia were boosted by
mergers and takeover activity and by signs that corporations were focusing more
intently on increasing shareholder value.

       The biggest gains were in the Pacific region and in emerging markets, the
bourses that had suffered the biggest declines during 1997 and 1998. The Pacific
region gained 27.4%, despite a continuing recession in Japan, while the MSCI
Select Emerging Markets Free Index rose 30.8%. European stocks were up nearly
20% in local currencies, but these gains were cut to 10.9% for U.S. investors
because of the dollar's gains against the euro, a common currency adopted by 11
nations, and other European currencies.

REPORT FROM THE ADVISER

[PHOTO]

What a difference six months can make in the global economy! In our letter to
you six months ago, the global capital markets seemed to be on the verge of a
meltdown. Asian economies, once termed the "Asian tigers" because of their
explosive growth, were suffering massive outflows of foreign capital, which put
enormous pressure on the value of their currencies. This spreading global
economic condition gave rise to a new phrase, the "Asian contagion." Russia had
recently defaulted on its debt. Latin America was considered the next in line
for this rolling calamity, as investors expected that Brazil might be next to
devalue its currency. Investors were rushing to the safety of U.S. Treasury
securities. The Federal Reserve Board had just lowered short-term interest rates
twice by a total of 0.5 percentage point. Ultimately, the Fed would trim
short-term rates by another quarter-point for a total reduction of 0.75
percentage point. At the time, as oil was dropping toward a price of $10 per
barrel and the yield of the 30-year Treasury bond was around 4.75%, the danger
of higher inflation was not registering in any of the government's statistics.

       Now, the world seems to have taken a step back from the brink of an
economic cliff. Most of Asia, with the exception of Japan, is showing signs of
recovery. If the performance of Asian stock markets is any indicator, investors
are embracing these economies again. Latin America's economies did not fall into
the abyss, as Brazil ultimately chose to devalue its currency. In January,
Europe's common currency, the euro, was introduced, linking the economic fates
of 11 European countries. On the whole, growth rates of these "Euroland"
economies have shown signs of slowing in the past few months. This factor,
coupled with the tensions of the Kosovo conflict, has resulted in a weakening of
the euro versus the U.S. dollar since the currency's introduction.

       Throughout all the turmoil, the American economy performed extremely
well, with its gross domestic product registering a 6.0% annual growth rate in
fourth-quarter 1998, followed by continued expansion at a 4.1% annual pace
during first-quarter 1999. As the U.S. economy continues to grow, the
unemployment rate remains low (4.3% as of this writing) and inflation has
remained subdued. Looking forward, the key question facing the capital markets
is whether inflation will accelerate. The Organization of Petroleum Exporting
Countries (OPEC) recently agreed to limit oil production. Several such
agreements have been made in the past, but compliance with them has always been
a challenge for OPEC's members. So far, however, the price of oil has increased
to approximately $18 per barrel, up almost 80% from December 1998. If other
commodities begin to register similar price increases, the low-inflation era may
be behind us.

       Given this backdrop, yields on the benchmark 30-year Treasury bond
increased 50 basis points (0.5 percentage point, from 5.16% to 5.66%) over the
last six months. Yields on municipal bonds followed the



                                       6
<PAGE>   9

same upward trend as their taxable brethren, although the magnitude of the move
was not nearly so pronounced for tax-exempt securities. The yield of a 30-year,
AAA- rated tax-exempt bond rose over the period by about 20 basis points (from
about 4.90% to 5.10%).

       During the half-year, the seven Vanguard Municipal Bond Funds provided
returns that reflected their differing exposure to interest rate risk. The funds
that possess the greatest market risk--those with the longest average
maturities--experienced the largest capital declines in this period of rising
yields. A bond's price moves in the opposite direction from its yield.
Therefore, the capital declines incurred offset, to one degree or another, the
income component of each fund's total return.

       Two factors explain the municipal bond market's relatively strong
performance in comparison with Treasury securities during the half-year. First,
municipal bonds closed fiscal year 1998 last October 31 with very attractive
yields compared with similar Treasury securities. In fact, for weeks on end,
long-term municipal bonds yielded more than Treasuries with identical maturity
dates, even though interest on municipals is exempt from federal taxes. The
global economic forces that led investors to seek the safety of Treasuries
contributed to making those securities relatively expensive and municipal bonds
relatively cheap. As we entered the new year and concerns about the global
economy subsided, yields of Treasury securities rose more than those on
municipal bonds. The second factor working in favor of municipals during the
half-year is that issuance of new municipal bonds declined in 1999.
Calendar-year 1998 saw the second-largest issuance of new municipal bonds in the
last ten years. This fact alone contributed to municipal bonds' underperformance
versus taxable bonds during calendar-year 1998. However, over the first quarter
of calendar 1999, the amount of new municipal bonds coming to market declined
21% from the same period in 1998.

       As always, the Vanguard Municipal Bond Funds have been managed in a
manner consistent with our core values. Our long-standing belief is that low
costs, coupled with prudent risk taking by professional managers with an eye
toward the long term, will produce consistently strong results for our
shareholders.

AVERAGE COUPON. The average interest rate paid on the securities held by a fund.
It is expressed as a percentage of face value.

AVERAGE DURATION. An estimate of how much a bond fund's share price will
fluctuate in response to a change in interest rates. To see how the price could
shift, multiply the fund's duration by the change in rates. If interest rates
rise by one percentage point, the share price of a fund with an average duration
of five years would decline by about 5%. If rates decrease by a percentage
point, the fund's share price would rise by 5%.

AVERAGE MATURITY. The average length of time until bonds held by a fund reach
maturity (or are called) and are repaid. In general, the longer the average
maturity, the more a fund's share price will fluctuate in response to changes in
market interest rates.

AVERAGE QUALITY. An indicator of credit risk, this figure is the average of the
ratings assigned to a fund's securities holdings by credit-rating agencies. The
agencies make their judgment after appraising an issuer's ability to meet its
obligations. Quality is graded on a scale, with Aaa or AAA indicating the most
creditworthy bond issuers and A-1 or MIG-1 indicating the most creditworthy
issuers of money market securities.

BETA. A measure of the magnitude of a fund's past share-price fluctuations in
relation to the ups and downs of the overall market (or appropriate market
index). The market (or index) is assigned a beta of 1.00, so a fund with a beta
of 1.20 would have seen its share price rise or fall by 12% when the overall
market rose or fell by 10%.

CASH RESERVES. The percentage of a fund's net assets invested in "cash
equivalents"--highly liquid, short-term, interest-bearing securities. This
figure does not include cash invested in futures contracts to simulate bond
investment.

DISTRIBUTION BY CREDIT QUALITY. This breakdown of a fund's securities by credit
rating can help in gauging the risk that returns could be affected by defaults
or other credit problems.

DISTRIBUTION BY MATURITY. An indicator of interest rate risk. In general, the
higher the concentration of longer-maturity issues, the more a fund's share
price will fluctuate in response to changes in interest rates.

EXPENSE RATIO. The percentage of a fund's average net assets used to pay its
annual administrative and advisory expenses. These expenses directly reduce
returns to investors.

INVESTMENT FOCUS. This grid indicates the focus of a fund in terms of two
attributes: average maturity (short, medium, or long) and average credit quality
(high, medium, or low).

LARGEST STATE CONCENTRATIONS. An indicator of diversification. The less
concentrated a fund's holdings of bonds, the less the fund will be hurt by any
financial problems in a single state or region.

NUMBER OF ISSUES. An indicator of diversification. The more separate issues a
fund holds, the less susceptible it is to a price decline stemming from the
problems of a particular issue.

R-SQUARED. A measure of how much of a fund's past returns can be explained by
the returns from the overall market (or its benchmark index). If a fund's total
return were precisely synchronized with the overall market's return, its
R-squared would be 1.00. If a fund's returns bore no relationship to the
market's returns, its R-squared would be 0.

YIELD. A snapshot of a fund's interest income. The yield, expressed as a
percentage of the fund's net asset value, is based on income earned over the
past 30 days (7 days for money market funds) and is annualized, or projected
forward for the coming year.

YIELD TO MATURITY. The rate of return an investor would receive if the
securities held by a fund were held to their maturity dates.

FINANCIAL STATEMENTS
APRIL 30, 1999 (UNAUDITED)

[PHOTO]

The Statements of Net Assets, integral parts of the Financial Statements for
each of the Vanguard Municipal Bond Funds, are included as an insert to this
report.

STATEMENT OF OPERATIONS

This Statement shows interest earned by each fund during the reporting period,
and details the operating expenses charged to the fund. These expenses directly
reduce the amount of investment income available to pay to shareholders as
tax-exempt income dividends. This Statement also shows any Net Gain (Loss)
realized on the sale of investments, and the increase or decrease in the
Unrealized Appreciation (Depreciation) on investments during the period. If a
fund invested in futures contracts during the period, the results of these
investments are shown separately.

STATEMENT OF CHANGES IN NET ASSETS

This Statement shows how each fund's total net assets changed during the two
most recent reporting periods. The Operations section summarizes information
detailed in the Statement of Operations. Because the fund distributes its income
to shareholders each day, the amounts of Distributions--Net Investment Income
generally equal the net income earned as shown under the Operations section. The
amounts of Distributions--Realized Capital Gain may not match the capital gains
shown in the Operations section, because distributions are determined on a tax
basis and may be made in a period different from the one in which the gains were
realized on the financial statements. The Capital Share Transactions section
shows the amount shareholders invested in the fund, either by purchasing shares
or by reinvesting distributions, and the amounts redeemed. The corresponding
numbers of Shares Issued and Redeemed are shown at the end of the Statement.

FINANCIAL HIGHLIGHTS

This table summarizes each fund's investment results and distributions to
shareholders on a per-share basis. It also presents the fund's Total Return and
shows net investment income and expenses as percentages of average net assets.
These data will help you assess: the variability of the fund's net income and
total returns from year to year; the relative contributions of net income and
capital gains to the fund's total return; how much it costs to operate the
fund; and the extent to which the fund tends to distribute capital gains. The
table also shows the Portfolio Turnover Rate, a measure of trading activity. A
turnover rate of 100% means that the average security is held in the fund for
one year. Money market funds are not required to report a Portfolio Turnover
Rate.

NOTES TO FINANCIAL STATEMENTS

Vanguard Municipal Bond Funds comprises the Tax-Exempt Money Market, Short-Term
Tax-Exempt, Limited-Term Tax-Exempt, Intermediate-Term Tax-Exempt, Insured
Long-Term Tax-Exempt, Long-Term Tax-Exempt, and High-Yield Tax-Exempt Funds,
each of which is registered under the Investment Company Act of 1940 as a
diversified open-end investment company, or mutual fund. Each fund invests in
debt instruments of many municipal issuers; the issuers' abilities to meet their
obligations may be affected by economic and political developments in a specific
state or region. Effective in 1997, each fund's fiscal year changed from August
31 to October 31.

A. The following significant accounting policies conform to generally accepted
accounting principles for mutual funds. The funds consistently follow such
policies in preparing their financial statements.

       1. SECURITY VALUATION: Tax-Exempt Money Market Fund: Investment
securities are valued at amortized cost, which approximates market value. Other
funds: Bonds, and temporary cash investments acquired over 60 days to maturity,
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.

       2. FEDERAL INCOME TAXES: Each fund intends to continue to qualify as a
regulated investment company and distribute all of its income. Accordingly, no
provision for federal income taxes is required in the financial statements.

       3. FUTURES CONTRACTS: Each fund, except the Tax-Exempt Money Market Fund,
may use Municipal Bond Index, U.S. Treasury Bond, and U.S. Treasury Note futures
contracts to a limited extent, with the objectives of enhancing returns,
managing interest-rate risk, maintaining liquidity, diversifying credit risk,
and minimizing transaction costs. The funds may purchase or sell futures
contracts instead of bonds to take advantage of pricing differentials between
the futures contracts and the underlying bonds. The funds may also seek to take
advantage of price differences among bond market sectors by simultaneously
buying futures (or bonds) of one market sector and selling futures (or bonds) of
another sector. Futures contracts may also be used to simulate a fully invested
position in the underlying bonds while maintaining a cash balance for liquidity.
The primary risks associated with the use of futures contracts are imperfect
correlation between changes in market values of bonds held by the funds and the
prices of futures contracts, and the possibility of an illiquid market.

       Futures contracts are valued based upon their quoted daily settlement
prices. The aggregate principal amounts of the contracts are not recorded in the
financial statements. Fluctuations in the values of futures contracts are
recorded in the Statement of Net Assets as an asset (liability) and in the
Statement of Operations as unrealized appreciation (depreciation) until the
contracts are closed, when they are recorded as realized futures gains (losses).

       4. DISTRIBUTIONS: Distributions from net investment income are declared
daily and paid on the first business day of the following month. Annual
distributions from realized capital gains, if any, are recorded on the
ex-dividend date.

       5. OTHER: Security transactions are accounted for on the date securities
are bought or sold. Costs used to determine realized gains (losses) on the sale
of investment securities are those of the specific securities sold. Premiums and
original issue discounts are amortized and accreted, respectively, to interest
income over the lives of the respective securities.

B. The Vanguard Group furnishes at cost investment advisory, corporate
management, administrative, marketing, and distribution services. The costs of
such services are allocated to each fund under methods approved by the Board of
Trustees. Each fund has committed to provide up to



                                       30

The funds' Trustees and officers are also Directors and officers of Vanguard.

C. The funds' investment adviser may direct new issue purchases, subject to
obtaining the best price and execution, to underwriters who have agreed to
rebate or credit to the funds part of the underwriting fees generated. Such
rebates or credits are used solely to reduce the funds' management and
administrative expenses. The funds' custodian bank has also agreed to reduce its
fees when the funds maintain cash on deposit in their non-interest-bearing
custody accounts. For the six months ended April 30, 1999, these arrangements
reduced expenses by:

                        Admiral Horatio Nelson's flagship
                          at the Battle of the Nile on
                          August 1, 1798. Our founder,
                          John C. Bogle, chose the name
                        after reading Nelson's inspiring
                      tribute to his fleet: "Nothing could
                          withstand the squadron . . .
                       with the judgment of the captains,
                      together with their valour, and that
                        of the officers and men of every
                  description, it was absolutely irresistible."

VANGUARD MUNICIPAL BOND FUNDS
FINANCIAL STATEMENTS
APRIL 30, 1999 (UNAUDITED)

[PHOTO]

The Statement of Net Assets should be read in conjunction with the Statement of
Operations, Statement of Changes in Net Assets, Financial Highlights, and Notes
to Financial Statements, all of which appear in the accompanying report.

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each fund's municipal bond holdings
by state, including each security's market value on the last day of the
reporting period and information on credit enhancements such as insurance or
letters of credit. Other assets are added to, and liabilities are subtracted
from, the value of Total Municipal Bonds to calculate the fund's Net Assets.
Finally, Net Assets are divided by the outstanding shares of the fund to arrive
at its share price, or Net Asset Value (NAV) Per Share.

       At the end of the Statement of Net Assets of each fund, you will find a
table displaying the composition of the fund's net assets on both a dollar and
per-share basis. Undistributed Net Investment Income is usually zero because the
fund distributes its net income to shareholders as a dividend each day. Any
realized gains must be distributed annually, so the bulk of net assets consists
of Paid in Capital (money invested by shareholders). The balance shown for
Accumulated Net Realized Gains usually approximates the amount available to
distribute to shareholders as taxable capital gains as of the statement date,
but may differ because certain investments or transactions may be treated
differently for financial statement and tax purposes. Any Accumulated Net
Realized Losses, and any cumulative excess of distributions over net realized
gains, will appear as negative balances. Unrealized Appreciation (Depreciation)
is the difference between the value of the fund's investments and their cost,
and reflects the gains (losses) that would be realized if the fund were to sell
all of its investments at their statement-date values.
