AT VANGUARD, WE BELIEVE THAT TRADITION MATTERS

Our 9,000 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.

Bond prices slid during the first half of Vanguard Bond Funds' fiscal year amid
growing concerns that strong economic growth would touch off higher inflation.
In this difficult environment for fixed-income investments, seven of our nine
funds registered negative returns for the six months ended July 31, 1999. Our
returns ranged from +0.6% for our Short-Term Corporate Fund to -8.0% for our
Long-Term Treasury Fund.

       The table below presents the six-month total return (capital change plus
reinvested dividends) for each fund compared with those of its average mutual
fund competitor. Details on each fund, including per-share net asset values,
income dividends, and any capital gains distributions, are presented in the
table that follows this letter. The table also lists the annualized yields of
each fund, which on July 31 ranged from 5.49% for our Short-Term Treasury Fund
to 8.93% for our High-Yield Corporate Fund.

       We believe that any semiannual review of bond fund returns should also
include a look at a full year's interest income. That's because semiannual
returns for bond funds account for only half of the year's interest income,
whereas price changes occur immediately in response to changes in interest
rates. Over the long run, however, the price effects of fluctuating interest
rates tend to be offsetting, so interest income accounts for virtually all of
the total return on a bond fund. The table on page 2 presents each fund's
return for the past twelve months, divided into its income and capital
components. The impact of the rise in interest rates over the past twelve
months--particularly on the Long-Term Corporate Fund and the Long-Term Treasury
Fund--is clearly illustrated. As you know, bond prices and bond yields move in
opposite directions. And prices of long-term bonds suffer most when interest
rates rise, just as they benefit most from a decline in rates. For further
information on capital and income returns for each fund, see the Performance
Summaries beginning on page 11.

THE PERIOD IN REVIEW

The U.S. economy's impressive expansion, a strong showing in corporate profits,
and a general improvement in business conditions around the world pushed stock
prices higher during the six months ended July 31.

       But as is often the case, good news about economic growth was bad news
for the bond market. Throughout the period, bond investors grew increasingly
concerned that factors such as low unemployment (which puts pressure on
employers to raise wages) and a rebound in commodity prices (which can increase
the prices of finished goods) would push up overall inflation. Bond investors
are particularly attuned to hints of higher prices because inflation erodes the
purchasing power of future interest and principal payments.

       Yields of fixed-income securities moved higher across the board during
the half-year. Early in the period, the Federal Reserve Board sent several
signals that it was prepared to act swiftly to head off higher inflation. Then
on June 30, it hiked its target for short-term interest rates by 25 basis
points (0.25 percentage point), an action that typically provokes rate
increases for other maturities as well. The yield of the benchmark 30-year U.S.
Treasury bond increased more than a full percentage point on balance during the
half-year, beginning the period at 5.09% and ending it at 6.10%. The rise in
the yield of the 10-year Treasury bond was even more significant. The 10-year
bond ended the period at 5.90%--fully 125 basis points higher than its starting
point. At the short end of the spectrum, the yield of the 3-month T-bill rose
on balance from 4.45% to 4.75%. Late in the period, the spread between yields
of higher-quality and lower-quality bonds widened considerably as investors
demanded additional compensation for the higher risk of more speculative debt.

       The Lehman Aggregate Bond Index, an unmanaged measure of the entire U.S.
bond market, provided a return of -2.5% for the six months.

       The U.S. stock market, meanwhile, advanced broadly. The Wilshire 5000
Total Market Index, which tracks the entire U.S. stock market, was up +4.4%
during the half-year. Small-capitalization stocks, which returned +4.9% (as
measured by the Russell 2000 Index), slightly outperformed large-caps, which
gained +4.5% (as measured by the S&P 500 Index). The market's gain was not
straight up, however. The Wilshire 5000 Index declined in three of the six
months, including a -3.1% slide in July.

PERFORMANCE OVERVIEW

During the half-year ended July 31, not only were bond returns disappointing,
but the returns of most of the Vanguard Bond Funds fell short of the returns of
similar mutual funds. The highest return of our nine funds was recorded by the
SHORT-TERM CORPORATE FUND, which returned +0.6%. And of our nine funds, only
two--SHORT-TERM FEDERAL and SHORT-TERM CORPORATE--outpaced their average peers.

       The negative returns posted by each of our intermediate-term and
long-term funds were deeper than the declines registered by their average peers.
The -8.0% return of the LONG-TERM TREASURY FUND trailed by 2.6 percentage points
the -5.4% return of the average long-term Treasury bond fund, and the -3.5%
return of the INTERMEDIATE-TERM CORPORATE FUND was a full percentage point lower
than that of its average competitor. The explanation for the shortfall is
straightforward: The average maturities of our funds are generally longer than
those of their average peers. For example, the average weighted maturity of our
Long-Term Treasury Fund is 20.1 years, while the average maturity of its
comparative group is just over 15 years. In addition, the 18.2-year maturity of
our Long-Term Corporate Fund is more than 8 years longer than the average
maturity of its comparative group. As noted earlier, longer maturities mean
higher yields and a more durable income stream, but also an increased
sensitivity to changes in interest rates.

       It's important to understand that this significant difference between our
funds and their peers works both ways. When interest rates are declining--as
they have been for the better part of the past decade--our funds have an
advantage over their average peers. And for long-term investors who are not
concerned with interim price fluctuations, a rise in rates can be good news.
Overall, the yields of our funds as of July 31 were about a full percentage
point higher than six months ago.

       Our GNMA FUND, which has an intermediate-term average maturity and
invests in mortgage-backed securities, provided a return of -1.8%, just a hair
off the -1.7% return of the average GNMA mutual fund. Mortgages fared better
than bonds with similar maturities during the period because one of the chief
risks of GNMA bonds--that the securities will be prepaid and replaced with
lower-interest securities--declines as interest rates rise. For further
information about the mortgage-backed bond market, see the Report From the
Adviser on page 9.

       Finally, our HIGH-YIELD CORPORATE FUND returned -0.6% for the half-year,
well behind the relatively strong +2.0% return of the average high-yield bond
fund, which invests in riskier securities than those held by our fund. This
quality difference is a disadvantage for our fund during periods when
lower-quality issues outperform higher-quality debt.

       Our funds generally fell in line with their unmanaged index benchmarks.
This accomplishment is notable because our funds incur expenses that the
indexes do not. However, we recognize that beating or matching an index is
small consolation in periods when our returns are negative or barely positive.

       We believe that our policy of maintaining longer maturities will pay off
for shareholders because longer maturities normally provide higher yields, and
higher yields are the key to higher long-term returns. What is more, our funds
are aided in their quest to provide superior yields by their extremely low
expenses. Our funds have annualized expense ratios (expenses as a percentage of
average net assets) of 0.30% or lower, whereas the expense ratio of the average
fixed-income fund is 1.05%, giving us a remarkable 75 basis



                                       3

points (0.75 percentage point) advantage, holding quality and maturity
constant. To garner such an advantage in the bond fund field is, finally, the
key to our performance successes.

IN SUMMARY

During times when interest rates are rising, investors who take a short-term
view of the financial markets can find it difficult to justify a place for
bonds in their investment programs. But those who are investing for the long
haul understand that the benefits of low-cost bond funds--diversification and
compounded interest income--can be substantial. That's why we remain steadfast
in our belief that creating and maintaining a balanced investment program of
stock funds, bond funds, and short-term reserves tailored to your goals, time
horizon, and tolerance for risk is the surest route to long-term investment
success.

       We look forward to reporting to you on the full fiscal year in our 2000
annual report six months hence.

THE MARKETS IN PERSPECTIVE
SIX MONTHS ENDED JULY 31, 1999

[PHOTO]

An improving global economy was the backdrop for generally higher stock prices
but lower bond prices during the six months ended July 31.

       A powerful expansion of the U.S. economy--which is by far the world's
largest--attracted record levels of imported products, helping foreign
economies to begin recovering from recessions. Confidence grew that global
economic activity was likely to be solid, if unspectacular, throughout 1999,
with further gains expected in 2000. This was a marked change in sentiment from
autumn 1998, when many analysts feared that economic troubles in Asia, Latin
America, and Russia would eventually weaken even the robust U.S. economy. The
turnabout was due, in part, to actions by the Federal Reserve Board and other
central banks to ease monetary policy to foster growth and restore confidence
to financial markets.

       As economic engines revved up during 1999, market interest rates rose
steadily. The Fed tapped the brakes on June 30, when it acted to boost
short-term interest rates by 0.25 percentage point. The move clearly signaled
that the Fed was more concerned about the danger of inflation than any risk of
an economic slowdown.

U.S. STOCK MARKETS

Stock prices rose during the half-year, largely because investors' expectations
for improved corporate earnings outweighed their concerns about rising interest
rates. Companies reporting higher-than-expected earnings outnumbered those with
lower-than-expected earnings, and analysts raised estimates for overall
corporate profits in 1999 and 2000. The total market, as measured by the
Wilshire 5000 Index, rose 4.4% during the six months ended July 31, while the
S&P 500 Index, a yardstick for large-capitalization stocks, gained 4.5%.

*Annualized.

       Although stock returns seemed modest compared with the huge gains of
recent years, they were in line with historical norms and were impressive in
light of the rise in interest rates. Higher rates hurt stock prices because many
investors use current interest rates to discount the value of a stock's
projected earnings and dividends: the higher the rate used to discount them, the
lower the present value of future earnings and dividends.

       Within the stock market, leadership changed during the period. Value
stocks-- characterized by below-average share prices in relation to earnings,
dividends, and book

value--led the market's advance after having lagged growth stocks for most of
the past five years. Value stocks within the S&P 500 gained 8.3% for the six
months, while the index's growth stocks gained just 1.3%. Predominantly
value-stock industries such as energy, materials & processing, and machinery
were the big gainers during the half-year, buoyed by higher demand and prices
for oil and a number of other commodities. The worst-performing sectors were
health care (-7.6%) and consumer staples (-6.2%), both home to some
high-profile growth stocks that had infatuated investors until recently.

       Small-cap stocks, as measured by the Russell 2000 Index, gained 4.9% for
the half-year, marginally better than the return on large stocks. Even that
small victory is noteworthy, given that the Russell 2000's cumulative return
over the past three years (46.6%) lags that of the S&P 500 Index (118.1%) by
more than 70 percentage points.

U.S. BOND MARKETS

The rapid economic expansion that boosted prospects for stock prices made bond
investors wary. Although inflation was well-behaved--consumer prices rose 1.5%
for the six months and 2.1% for the twelve months ended July 31--both investors
and the Fed's policymakers were looking ahead, not behind. The concern is that
the economy is becoming overheated; inflation-adjusted gross domestic product
during the second quarter was up 5.4% from a year earlier. Too-rapid expansion
might yet trigger significant increases in wages and overall prices, many fear.
Indeed, thanks to high employment and rising wages, total U.S. wage and salary
income in June 1999 was 6.5% higher than in June 1998. Unless productivity--the
amount workers produce per hour--continues to rise at very rapid rates, such
wage growth could cause companies to boost prices for products and services.

       U.S. Treasury bond yields rose by roughly 1 percentage point--a hefty
boost for a six-month period. The yield of the 30-year Treasury bond rose 101
basis points, to 6.10% on July 31 from 5.09% on January 31. The yield of the
10-year Treasury--a benchmark especially for mortgage rates--rose 125 basis
points, to 5.90% from 4.65%. Money market rates didn't rise as far: Yields on
3-month T-bills increased on balance by 30 basis points, to 4.75% on July 31.
Bond prices, which move in the opposite direction from interest rates, fell.
The benchmark for the overall taxable bond market, the Lehman Aggregate Bond
Index, fell 2.5% on a total-return basis, as interest income of about 3.0% for
the six months was more than offset by a 5.5% average decline in bond prices.

INTERNATIONAL STOCK MARKETS

Stock prices in Japan and many emerging markets rebounded sharply from steep
losses in 1997 and 1998, as investors reckoned that these nations' economies
were finally on the mend. In Europe, stock prices were modestly higher in
local-currency terms but slightly negative for U.S. investors because of the
U.S. dollar's gains against European currencies. (Returns from abroad are
diminished when the dollar's value rises against other currencies, and
augmented when the dollar falls in value.)

       Overall, the developed markets outside the United States gained 7.5% in
U.S.-dollar terms, as measured by the Morgan Stanley Capital International
Europe, Australasia, Far East (EAFE) Index. The Pacific region was up 27.8% in
local-currency terms and 29.5% for U.S. investors, because the Japanese yen
gained against the dollar. Europe, which accounts for the lion's share of EAFE's
market capitalization, was up 3.7% in local currencies. But in U.S. dollars, the
return from European stocks was -0.8% because of weakness in European
currencies. The MSCI Select Emerging Markets Free Index shot up 30.9%, led by
gains of more than 60% in Indonesia, Singapore, and Turkey.

REPORT FROM VANGUARD
FIXED INCOME GROUP

[PHOTO]

SHORT-TERM TREASURY, FEDERAL, AND CORPORATE FUNDS;
INTERMEDIATE-TERM TREASURY AND CORPORATE FUNDS; AND
LONG-TERM TREASURY FUND

During the six months ended July 31, 1999, returns from the bond market were
generally negative. Interest rates rose by about 1 percentage point, causing
price declines that on average more than offset the interest paid during the
half-year. Short-term bonds roughly broke even, but returns for intermediate-
and long-term bonds, whose prices are more sensitive to changing interest
rates, ranged from about -3% to about -8%. The Vanguard Bond Funds produced
returns that correspond with their average maturities.

       The forces behind the rise in interest rates during the half-year are
essentially the reverse of those that roiled global financial markets in the
latter part of 1998. At that time, the Federal Reserve Board lowered interest
rates to jump-start the capital markets after they had "seized up" in response
to Russia's default on its debts, hedge fund liquidations, and other crises.
However, in autumn 1998, fearful that poorly functioning markets would cut off
the flow of capital that sustains economic growth, the Fed engineered three
interest rate reductions that encouraged shell-shocked investors to buy. By the
start of our new fiscal year in February, it was becoming clear that the tonic
of lower rates had worked, and that the yield premiums required to induce
investors to assume credit, prepayment, and liquidity risks had contracted.

       For the bond market, the old phrase "be careful what you wish for" was
about to prove its truthfulness. Propelled by wage and employment growth and
rapidly accumulating wealth from stock investments, consumer spending surged and
soon had the economy firing on all cylinders. The housing sector, a catalyst for
consumption, was especially strong. In February, Federal Reserve Chairman Alan
Greenspan testified that the reduced interest rates of 1998 might no longer be
appropriate in an environment of restored confidence and strong economic
expansion. With productivity growth running above 2% (a high rate by historical
standards, although productivity is notoriously hard to measure with any
precision), Chairman Greenspan had in recent years experimented with letting the
economy find the upper limits of noninflationary growth. However, he recently
indicated that he thought those limits might be at hand--that the shrinking
supply of available workers now threatened to push up wages and prices. In his
view, price stability is the key to sustained economic growth. The Fed therefore
acted to preempt inflation by raising short-term interest rates 0.25 percentage
point on June 30. The markets, implicitly forecasting future events, have
factored in one or possibly two more rate hikes in the next three months or so.

       In May, risk premiums ceased to narrow for fixed-income securities other
than Treasuries, and the spreads between yields on these securities and on
Treasuries have since dramatically widened. In relation to Treasury yields, the
yields of corporate, government agency, asset-backed, and mortgage-backed
securities are now



                                       7

<PAGE>   10

nearly as high as or, in some cases, higher than they were during the financial
markets' gridlock in autumn 1998. Last year, spreads widened because of
investors' fear of defaults on debts by emerging countries or overextended
hedge funds. Today's wide spreads, by contrast, stem from a large bulge in
supply. Many bond issuers have been trying to meet all their funding needs by
the third quarter, in case Y2K concerns make markets less liquid later in the
year. This is problematic, because investors had already bought plenty of these
bonds some months back when they offered attractively wide yields relative to
Treasuries in the wake of the 1998 crisis.

       While the current wide spreads are very attractive by historical
standards, many investors have acquired all the non-Treasury bonds they care to
hold and are concerned with maintaining some degree of liquidity themselves.
Further aggravating this situation is the increasing reluctance of securities
dealers to commit their capital to market-making activities. With dealers
unwilling to hold large inventories of securities, newly issued bonds have to
be priced cheap--offering high yields--to attract the marginal buyer.

       In the face of recent volatility and uncertainty, we have applied some
consistent themes in managing the Vanguard Bond Funds. Anticipating rising
rates, we have been shading the interest-rate sensitivity of most of the funds
toward the lower end of our neutral duration policies. While the funds' average
maturities remain true to their names, this slight shortening of maturities
marginally cushions the negative impact of rising rates on share prices.

       We find today's wide credit-risk premiums for corporate bonds to be very
attractive. It is our view that the economy will continue to grow at a healthy
pace, which should bolster the creditworthiness of corporate bond issuers.
Despite the recent volatility in yield spreads versus Treasuries, we are keeping
our corporate bond funds fully invested in corporate issues. In the same vein,
we are investing a portion of our Treasury funds' assets in U.S. government
agency bonds (as permitted by the prospectus) to capture the added income
offered by the wide spreads between their yields and those on Treasury bonds.

       The wide variety of risk/return combinations available from the Vanguard
Bond Funds enables investors to match their own needs fairly closely. However,
it is important to bear in mind that risk and return relationships change, and
investors should periodically reevaluate their holdings. At present, for
example, an investor willing to accept a bit more credit risk can get
significantly higher income from high-quality corporate bonds than from
Treasury bonds.

       What will not change about the Vanguard Bond Funds is our commitment to
disciplined portfolio management at the lowest possible cost.

INVESTMENT PHILOSOPHY

The funds reflect a belief that no one bond portfolio is right for all
investors. The funds offer an array of portfolios with specific maturity and
quality characteristics so investors can select the portfolio or combination of
portfolios appropriate to their needs.

REPORT FROM WELLINGTON
MANAGEMENT COMPANY, LLP

GNMA FUND; LONG-TERM CORPORATE FUND; AND HIGH-YIELD CORPORATE FUND

In any given period, changes in the level and direction of interest rates are
the most important determinants of absolute performance for the GNMA, Long-Term
Corporate, and High-Yield Corporate Funds. However, changes in rates affect
each fund differently.

       During the last six months, yields on intermediate-term Treasury
securities rose about 125 basis points (1.25 percentage points), causing the
prices of existing fixed-income securities to fall. The average rate on home
mortgage loans rose past 8%, pushing up borrowing costs for homeowners, which
will have some mild slowing effects on the economy. Interest rates were rising
throughout the half-year, well before the Federal Reserve Board acted on June
30 to increase short-term rates. While risk premiums on corporate bonds are
generally lower than they were last autumn during the crises in global markets
stemming from Russia's defaults on its debt, they are still high by normal
standards. The wider spreads between yields on corporate bonds and those on
Treasuries exist even though corporate profits are strong and the domestic
economy is healthy--conditions that ordinarily would keep risk premiums
relatively narrow.

       Currently, the flow of new investment-grade corporate bonds is strong
while the issuance of high-yield, or below-investment-grade, securities is
modest. Mortgage-backed securities offer very enticing yields, given that the
risk of refinancing and prepayments by homeowners is low because of the rise in
rates. If rates do not drop sharply, prepayments of principal on mortgages
won't be significant, and today's yield premium on GNMA issues will turn out to
be overly generous. If rates stay relatively stable over the next six months,
current yields on high-yield bonds and long-term corporate bonds offer
reasonable value.

GNMA FUND

Your GNMA Fund's share price declined during the half-year because interest
rates rose, but the decline was modest compared with those experienced by
longer-term bond funds. The yields of GNMA securities rose further than those of
comparable Treasury securities during the past six months. This was unusual.
Typically, rising interest rates mean a slowdown in mortgage refinancing, which
benefits the GNMA Fund and causes its yield to rise less rapidly than yields of
comparable Treasuries. But this time there has been no such effect, even though
refinancing rates have been falling. The upshot is that, although the recent
period has been a trying one for shareholders, we believe the current yield of
your GNMA Fund offers not only attractive current income but also the prospect
of good total return should interest rates stabilize.

LONG-TERM CORPORATE FUND

The average maturity of the Long-Term Corporate Fund's investments is about 18
years, in keeping with its charter. The fund's average duration--slightly under
nine years--is also long, making the share price extremely sensitive to changes
in long-term interest rates. It's important for shareholders to understand this
sensitivity. For example, if market interest rates move up or down by 100 basis
points (1 percentage point), the fund's net asset value would be expected to
fall or rise by 9%. Because rates rose by about 1 percentage point during the
semiannual period, the fund's return was negative. The fund has excellent call
protection, which means that most of our holdings cannot be redeemed by their



                                       9

<PAGE>   12

issuers if rates decline. The fund's income stream therefore has some
protection from falling interest rates.

       The major risk for this fund is the possibility of an extended rise in
long-term interest rates, which would cause its share price to keep falling.
More than half of our assets are invested (and are intended always to be so) in
corporate bonds with an average maturity longer than 15 years.

       A second risk always present in this fund is that deterioration of the
creditworthiness of corporate bond issuers could hurt the value of our holdings.
To mitigate this risk, the fund is well diversified by issuer and industry. We
have recently seen a healthy trend in which upgrades of credit ratings have been
outpacing downgrades in the investment-grade market. More than 80% of the fund's
assets are invested in issues rated A or better. The fund does not own
below-investment-grade corporate bonds, emerging-market debt, or foreign bonds
denominated in non-U.S. currencies. We generally purchase bonds of
well-established, large companies with stable operating histories.

HIGH-YIELD CORPORATE FUND

The below-investment-grade bond market continues to act like a hybrid. Under
some market conditions, high-yield bonds follow the direction of the stock
market; at other times, they behave like the rest of the bond market. And
sometimes they act like neither. For example, during the second quarter of 1999,
downgrades of credit ratings outpaced upgrades in the high-yield market--the
reverse of the trend among investment-grade bonds. Energy and health-care
companies were most affected by the downgrades. This deterioration in ratings of
speculative-grade bonds caused a widening in the yield spread versus Treasury
securities, which hurt your fund's performance. During this period, the domestic
economy and the stock market remained vibrant, which would have supported the
high-yield market had rating downgrades been less numerous.

       With the Federal Reserve raising interest rates and, thus, implicitly
restricting credit, the high-yield market probably will be kept slightly off
balance. When credit is tighter, the marginal, or lower-rated, borrower must pay
relatively steep yields to obtain credit. We have begun to see this phenomenon.
Investors' tolerance for risk will decrease if economic growth begins to slow,
as the Fed seems to prefer.

       We remain very selective with respect to credit quality. We are avoiding
bonds of smaller, start-up companies and continuing to emphasize the
higher-quality end of the below-investment-grade market.

       As always, we conduct in-depth research on a company-by-company basis and
emphasize diversification. The fund's holdings remain focused on cash-paying
issues rated B or better. We maintain a modest reserve of Treasury securities in
case we need liquidity.

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. U.S. Treasury securities are considered to
have the highest credit quality.

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 COUPON. A breakdown of the securities in a fund according to
coupon rate--the interest rate that an issuer promises to pay, expressed as an
annual percentage of face value. Securities with unusually high coupon rates
may be subject to call risk, the possibility that they will be redeemed (or
"called") early by the issuer.

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 ISSUER. A breakdown of a fund's holdings by type of issuer or
type of instrument.

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 (Treasury/agency, investment-grade corporate, or below
investment-grade).

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 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
JULY 31, 1999 (UNAUDITED)

[PHOTO]

The Statements of Net Assets, integral parts of the Financial Statements for
each of the Vanguard Bond Funds, are included as an insert to this report
(except for the GNMA Fund, whose Statement of Net Assets is provided below).

STATEMENT OF NET ASSETS

This Statement provides a detailed list of each fund's holdings, including each
security's market value on the last day of the reporting period. Securities are
grouped and subtotaled by bond type (U.S. government and agency issues,
corporate bonds, foreign bonds, etc.); corporate bonds are further classified
by industry sector. Other assets are added to, and liabilities are subtracted
from, the value of Total Investments 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. 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 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.

STATEMENT OF OPERATIONS

This Statement shows interest earned by each fund during the reporting period,
and details the operating expenses charged to each class of its shares. These
expenses directly reduce the amount of investment income available to pay to
shareholders as 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. Distributions, Capital Share Transactions, and Shares Issued and
Redeemed are shown separately for each class of shares.

FINANCIAL HIGHLIGHTS

This table summarizes each fund's investment results and distributions to
shareholders on a per-share basis for each class of shares. It also presents
the 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.

NOTES TO FINANCIAL STATEMENTS

Vanguard Bond Funds comprise the Vanguard Short-Term Treasury, Short-Term
Federal, Short-Term Corporate, Intermediate-Term Treasury, Intermediate-Term
Corporate, GNMA, Long-Term Treasury, Long-Term Corporate, and High-Yield
Corporate Funds, each of which is registered under the Investment Company Act
of 1940 as a diversified open-end investment company, or mutual fund. Certain
of the funds' investments are in corporate debt instruments; the issuers'
abilities to meet these obligations may be affected by economic developments in
their respective industries.

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

       1. SECURITY VALUATION: 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. Securities for which market quotations
are not readily available are valued by methods deemed by the Board of Trustees
to represent fair 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. REPURCHASE AGREEMENTS: Each fund, along with other members of The
Vanguard Group, transfers uninvested cash balances to a Pooled Cash Account,
the daily aggregate of which is invested in repurchase agreements secured by
U.S. government securities. Securities pledged as collateral for repurchase
agreements are held by a custodian bank until the agreements mature. Each
agreement requires that the market value of the collateral be sufficient to
cover payments of interest and principal; however, in the event of default or
bankruptcy by the other party to the agreement, retention of the collateral may
be subject to legal proceedings.

       4. FUTURES CONTRACTS: Each fund may use Municipal Bond Index, U.S.
Treasury Bond, and U.S. Treasury Note futures contracts, 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 value of the 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).

       5. 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.

       6. 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
discounts on debt securities purchased are amortized and accreted, respectively,
to interest income over the lives of the respective securities. Fees assessed on
redemptions of Vanguard High-Yield Corporate Fund capital shares are credited to
paid in capital.

B. The Vanguard Group furnishes investment advisory services to the Vanguard
Short-Term Treasury, Short-Term Federal, Short-Term Corporate,
Intermediate-Term Treasury, Intermediate-Term Corporate, and Long-Term Treasury
Funds on an at-cost basis.

       Wellington Management Company, LLP provides investment advisory services
to the Vanguard GNMA, Long-Term Corporate, and High-Yield Corporate Funds for
fees calculated at an annual percentage rate of average net assets. For the six
months ended July 31, 1999, the investment advisory fees of the Vanguard GNMA,
Long-Term Corporate, and High-Yield Corporate Funds represented effective
annual rates of 0.01%, 0.03%, and 0.04%, respectively, of average net assets.

C. The Vanguard Group furnishes at cost corporate management, administrative,
shareholder account maintenance, 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 0.40% of its net
assets in capital contributions to Vanguard. At July 31, 1999, the funds had
contributed capital to Vanguard (included in Other Assets) of:

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

D. The funds' investment advisers 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 banks have also agreed to reduce
their fees when the funds maintain cash on deposit in their
non-interest-bearing custody accounts. For the six months ended July 31, 1999,
these arrangements reduced expenses by:

E. The Short-Term Corporate Fund offers two classes of shares, Investor Shares
and Institutional Shares. Institutional Shares are designed primarily for
institutional investors that meet certain administrative and servicing criteria
and have a minimum investment of $50 million. Investor Shares are offered to
all other investors. Both classes of shares have equal rights to assets and
earnings, except that each class bears certain class-specific expenses related
to its shareholder activity. Class-specific expenses for the six months ended
July 31, 1999, represented the following percentages of average net assets:

Cash collateral received is invested in repurchase agreements. Security loans
are required to be secured at all times by collateral at least equal to the
market value of securities loaned; however, in the event of default or
bankruptcy by the other party to the agreement, retention of the collateral may
be subject to legal proceedings.

NOTICE TO SHAREHOLDERS ABOUT Y2K

As is well known by now, the approaching calendar change to 2000 has posed a
challenge to many computer systems worldwide. Computers that are not modified
could interpret "00" as 1900 rather than 2000 and produce errors in
date-dependent calculations, including bond interest payments, stock trade
settlements, retirement benefits, and other financial transactions.

OUR APPROACH

Vanguard has taken this challenge seriously. We have had a Year 2000 Project
under way since 1996 to fulfill our responsibility to safeguard our business
relationships and the security of our investors' accounts.

    Our internal systems are Year 2000-compliant. They have been renovated and
thoroughly tested and are ready for the date change. As for the external systems
that connect with ours, we have been working for many months with clients,
business partners, and providers of products and services to assess their
compliance. We have analyzed the external services we require and have developed
contingency plans-- including provision for alternative providers where
appropriate.

    On New Year's Day, our telephone centers will be staffed and ready for
shareholder calls. However, we expect the volume of inquiries over the New
Year's weekend to be high, and we encourage shareholders to check their accounts
via our website or automated telephone systems, which offer much greater service
capacity and efficiency. This will also help our live representatives to provide
a higher level of service to those with specific transaction or other
service-related needs.

WHAT YOU CAN DO

We assure you we will protect our shareholders' records, so account records
will not be lost. Nevertheless, keeping copies of current records is always
advisable. You should keep at least your third-quarter statement and any
confirmations you receive from us between October 1, 1999, and year-end.

    If you are a registered user of Access Vanguard(TM) (www.vanguard.com), you
can retrieve this information through the secure "Your Accounts" section and
print copies for your files. If you are not registered for Access Vanguard and
wish to have this flexibility, you should register as soon as possible so that
you can receive your password and become familiar with this service before the
New Year's weekend. Likewise, you may need personal identification numbers to
use our automated telephone services: Vanguard Tele-Account(R) for individual
investors (1-800-662-6273) and The VOICE(TM) Network for participants in
employer-sponsored retirement plans (1-800-523-1188).

    Our Year 2000 Project's primary goal from the start has been to prepare our
systems for business as usual on behalf of our shareholders into 2000 and
beyond. We remain confident we will meet that goal, and we look forward to
serving you in the years to come.

                             The Vanguard Group is
                            named for HMS Vanguard,
                       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."

                       The Vanguard Group's oldest fund,
                        was incorporated by Mr. Morgan
                      70 years ago, on December 28, 1928.
                           The fund was named after
                            the Duke of Wellington,
                             whose forces defeated
                           Napoleon Bonaparte at the
                          Battle of Waterloo in 1815.

VANGUARD BOND FUNDS
FINANCIAL STATEMENTS
JULY 31, 1999 (UNAUDITED)

[THE VANGUARD GROUP 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. The
Statement of Net Assets for the GNMA Fund begins on page 26 of that report.

STATEMENT OF NET ASSETS
This Statement provides a detailed list of each fund's holdings, including each
security's market value on the last day of the reporting period. Securities are
grouped and subtotaled by bond type (U.S. government and agency issues,
corporate bonds, foreign bonds, etc.); corporate bonds are further classified by
industry sector. Other assets are added to, and liabilities are subtracted from,
the value of Total Investments 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. 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 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.
