<PAGE>   2



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.

This year, 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, 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.
   
- -  The 70th anniversary, on December 28, 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.

Aided by a benign inflation outlook and a wave of purchases by investors who
sought refuge from turmoil in international markets, prices of most bonds rose
during the fiscal year for the Vanguard Bond Funds. In this environment--in
which higher quality and longer maturities were rewarded--each of our nine funds
earned twelve-month returns that surpassed those of similar mutual funds.

       As is usual, the funds' twelve-month returns varied considerably
according to maturity and credit quality. Our Long-Term Treasury Fund earned the
highest return with an excellent +12.0% advance, nearly half of which came from
capital appreciation. The lowest return, +5.3%, was provided by our High-Yield
Corporate Fund, which has the lowest credit quality in the group.

       The table below presents the twelve-month total return (capital change
plus reinvested dividends) for each fund, broken down into capital and income
components. The table also shows each fund's yield as of January 31, 1999.

       Prices of most of our funds, particularly the intermediate- and long-term
funds, benefited from the decline in interest rates during the fiscal year.
However, it's important to understand that interest-rate movements also can
lower bond prices. Prices of existing bonds move in the opposite direction from
market interest rates, so the market value of bonds (and bond funds) rises when
interest rates fall and declines when rates move higher. The effect is most
significant for longer-term bonds, which are more sensitive than shorter-term
securities to interest-rate changes. The extent of the interest-rate effect can
be seen in a bond fund's capital return--that is, the change in per-share value,
excluding interest income.

       A look back at the past decade shows that negative capital returns are
not uncommon. For example, the Long-Term Treasury Fund posted capital returns of
+5.8% in fiscal 1999 and +9.7% in fiscal 1998. But in fiscal 1995, when the
Federal Reserve Board hiked short-term interest rates six times, the fund had a
capital return of -13.0%, and in fiscal 1997 the fund's capital return was
- -8.2%. This history provides a valuable lesson about the short-term variability
of bond values. As we have explained in previous reports, our funds have longer
average maturities than most of their competitors and, therefore,

                                        1

are more sensitive to changes in interest rates. We believe that this policy,
which in the short term can work to our advantage or to our detriment, is in the
best long-term interest of our fund shareholders.

       Per-share figures for each fund, including net asset values, income
dividends, and any capital gains distributions, are listed in a table that
follows this letter. Also presented there is performance information for the
Institutional Shares of Vanguard Short-Term Corporate Fund, which earned a total
return of +6.3% for the year.

FINANCIAL MARKETS IN REVIEW

During the twelve months ended January 31, 1999, the U.S. economy expanded
impressively, inflation remained very low, and unemployment hovered around a
three-decade low. It was a terrific setting for both stocks and bonds.

       However, financial turmoil overseas was felt in the United States during
the summer when investors around the globe were spooked by the continuing
economic and currency troubles in Asia, a debt default in Russia, and concern
that the credit crisis in Brazil would spread through Latin America. In
response, some investors both at home and abroad scrambled to the relative
safety of U.S. Treasury bonds and shunned securities perceived to be riskier.
This so-called flight to quality resulted in sharp price increases for
Treasuries, which offer the highest credit-quality backing available: the full
faith and credit of the U.S. government. Investors' sudden reevaluation of risk
also resulted in steep price declines for stocks, low-grade bonds, and even
high-quality corporate bonds.

       The yield of the 30-year Treasury bond, which started the fiscal year at
5.80%, crept up to 6.07% in late April. But yields steadily declined during the
late summer and early fall in response to several factors: good news on
inflation, fears of a global economic slump, and a slightly tighter supply of
Treasuries--the result of a growing federal budget surplus. The long bond's
yield bottomed out at 4.72% on October 5. The Fed acted to help restore
liquidity to the credit markets and to head off an expected slowdown in U.S.
economic growth by trimming short-term interest rates by a total of 0.75
percentage point from late September through mid-November. During the final
three months of our funds' fiscal year, liquidity concerns eased, Treasury
prices declined, and the yield of the 30-year Treasury rose, ending the period
at 5.09%, 71 basis points below its starting point. The yield on 10-year
Treasuries fell 85 basis points on balance to 4.65%, and the yield of 3-year
Treasuries declined 71 basis points to 4.62%.

       The Lehman Brothers Aggregate Bond Index, a measure of the entire U.S.
bond market, including Treasuries as well as mortgage-backed securities and
high-quality corporate issues, earned a solid +8.1% for the twelve months. The
+12.3% return of the Lehman Long U.S. Treasury Bond Index was nearly 11
percentage points higher than the 1.7% inflation rate recorded for the fiscal
year. The story was much different at the lower end of the quality spectrum. For
the twelve months ended January 31, the Lehman High Yield Bond Index returned
just +1.6%, as a negative capital return of -6.8% offset nearly all of the
index's +8.4% income return.

       Meanwhile, large U.S. stocks soared during the twelve months, despite the
summer setback, and the Standard & Poor's 500 Composite Stock Price Index
advanced +32.5%. Small stocks, however, earned a scant total return of +0.3%, as
measured by the Russell 2000 Index. The entire U.S. stock market, as measured by
the Wilshire 5000 Equity Index, was up +27.4%.

FISCAL 1999 PERFORMANCE OVERVIEW

Overall, it was an excellent twelve months for our nine bond funds, which
outpaced their average peers, matched up well with unmanaged indexes for the
market segments in which they invest, and provided a comfortable margin over
inflation. Over the past 15 years, our funds have provided superior annual
returns relative to their competitors 83% of the time (in 83 comparisons out of
100--a total that reflects the varying lengths of time our funds have existed).

       Generally, our fine relative performance was the result of our funds'
longer average maturities and much lower costs. As you would expect, then, in a
fiscal year when interest rates declined, our long-term funds provided the
highest returns and the largest performance advantages over their peers. The
+12.0% return of the Long-Term Treasury Fund was 3.5 percentage points above the
+8.5% earned by the average long-term Treasury fund. Our Long-Term Corporate
Fund returned +9.5% (aided by a +2.9% capital return), well above the +6.9%
return of the average long-term corporate bond mutual fund. Our short- and
intermediate-term funds, which are less sensitive to changes in interest rates,
outpaced their peers by margins ranging from 0.6 percentage point to 1.8
percentage points. The adjacent table presents our returns compared with those
of peer funds.

- -----------------------------------------------------------------------------------------------------
</TABLE>

       Though our High-Yield Corporate Fund had the lowest absolute return of
our nine funds, it registered the biggest edge over its average peer. The fund's
+5.3% return was more than 6 percentage points higher than the -0.9% return of
the average high-yield fund. This margin was due to the significantly higher
quality of our fund's holdings compared with those in the average high-yield
bond fund, which typically holds a higher percentage of its assets in riskier,
and thus higher-yielding, securities. Our fund holds about 95% of its assets in
bonds rated "B" or higher, while the average peer holds a 16% stake in bonds
rated below "B." We are able to hold bonds of well-above-average quality for the
group, all the while offering above-average yields--a rare combination made
possible by our low costs.

       When the economy is strong and the risk of default is perceived to be
low, poorer-quality debt can perform strongly. This was the case throughout most
of the 1990s. In fact, from January 31, 1991, through January 31, 1999--a period
that covers eight fiscal years for our funds--the Lehman High Yield Index
returned an annualized +14.5%. However, lower-quality securities can suffer when
the economy slows or when investors flee from risk, as they did in late 1998.

       Our GNMA Fund earned its coupon during the fiscal year, returning +6.8%,
compared with the +6.0% return of the average GNMA fund. Mortgage-backed
securities typically offer higher yields and react more modestly to
interest-rate changes than do

                                        3

<PAGE>   6



other intermediate-term securities. However, when interest rates are falling,
homeowners are more likely to refinance their loans at lower rates. This
prepayment risk reduces the attractiveness of GNMAs relative to other bonds. So,
while mortgage-backed securities generally earned more interest income than
intermediate-term Treasury and corporate securities during the twelve months,
their capital returns and total returns were slightly lower.

LONG-TERM PERFORMANCE OVERVIEW

The table below summarizes each fund's long-term total return, comparing it with
the average return of comparable mutual funds during the same period. It also
shows how a $10,000 investment in each Vanguard fund would have grown over those
periods. The Performance Summaries on pages 14 through 23 give details of the
funds' long-term performance, including charts showing each fund's cumulative
returns for the past ten years (or its lifetime) and year-by-year breakdowns of
its income and capital returns.

       Over these longer periods, each of our funds has established a solid
performance edge over bond mutual funds with similar quality and maturity. On an
annualized basis, these margins ranged from +0.5% for our High-Yield Corporate
Fund to +2.3% for our Long-Term Corporate Fund. For our shareholders, such an
edge has translated into significant extra returns, as the table shows. For
example, a $10,000 investment made ten years ago in our Long-Term Corporate Fund
would, with dividends and capital gains distributions reinvested, have grown to
$27,897, compared with $22,537 in its average peer--an advantage of $5,360, or
nearly 54% of the initial investment.

       The ten-year record of our High-Yield Corporate Fund, reflecting an
annual outperformance of +0.5%, is particularly notable since our fund has
consistently carried lower risk, measured not only by higher quality, but also
by demonstrably lower price volatility.

       Note: For our Short-Term Treasury and Intermediate-Term Treasury Funds,
the period since inception covers a little more than seven years; for the
Intermediate-Term Corporate Fund, just over five years.

       There is no secret to our fine relative performance. It's simply a
combination of excellent management by our investment advisers and our tight
grip on costs, which gives us a significant advantage over our peer mutual
funds. Our funds' expense ratios (annual expenses as a percentage of average net
assets) for the fiscal year averaged about 0.28%--$2.80 per $1,000 invested--a
small fraction of the 1.05%, or $10.50 for every $1,000, charged each year by
the average fixed-income mutual fund.

       A mutual fund's expenses directly reduce the income and return it
produces. The drag of higher costs is especially evident in bond funds, which
typically derive most of their total return from interest income. Over time,
differences in costs account for virtually all of the difference in total
returns between mutual funds investing in bonds of similar maturity.

       Besides helping us outperform our higher-cost competitors, low costs also
help us closely track our benchmark indexes, which do not incur the operating,
advisory, and securities-transaction costs that real-world mutual funds must.

       When reviewing our longer-term performance, it's important to understand
that the returns shown here are almost certainly higher than those to be
expected in the near future. This is simply because rates are lower now than at
most points during the past decade. A relatively reliable indicator of future
long-term total returns on bond funds--though it is an imperfect one--is a
fund's current yield. Of course, if inflation remains low, current yields will
still provide a solid real, or after-inflation, income stream.

IN SUMMARY

The events of the past twelve months amply demonstrated the advantages of a
balanced investment approach. Investors who held a mix of stock funds, bond
funds, and money market funds participated in the market's bounty, but were
spared some measure of the anxiety felt during the midyear downturn in stocks.

       We have always believed that investors are well served by selecting a
balanced mix of assets appropriate to their investment time horizon, goals, and
risk tolerance, and then sticking with their plan. The volatility experienced by
most investors during 1998 and early 1999 has further reinforced our belief.

NOTE: You'll observe that we've made minor changes in the names of the Vanguard
Bond Funds, which formerly were called portfolios of Vanguard Fixed Income
Securities Fund. We removed "U.S." from our Treasury funds and replaced the word
"portfolio" with "fund" as part of a broader effort to simplify the names in our
fund lineup.

THE MARKETS IN PERSPECTIVE 
YEAR ENDED JANUARY 31, 1999

[PHOTO]

The twelve months ended January 31, 1999, were a volatile yet generally
rewarding period for financial markets. Despite a sharp midsummer slump, the
U.S. stock market closed the year with large gains: The overall market, as
measured by the Wilshire 5000 Equity Index, was up 27.4%. Stocks got a boost
from low inflation and generally declining interest rates, which also buoyed the
bond market. Overseas, gains were concentrated in Europe's developed markets,
while stocks fell in Asia and in most emerging markets.

U.S. STOCK MARKETS

The equity rise was concentrated to an unusual degree in large-capitalization
growth stocks. Large-cap stocks, as measured by the S&P 500 Index, gained
+32.5%, while the small-cap Russell 2000 Index eked out only a 0.3% return.
Growth stocks far outpaced value stocks within both large- and small-cap
indexes. The S&P 500's growth stocks earned +45.9%, versus 18.5% for the value
stocks in the index, while the growth component of the Russell 2000 earned 7.2%,
versus -6.9% for the value-stock component.

       In part, this growth-stock bias reflected the market's infatuation with
technology stocks. The technology sector led others by a wide margin, with tech
stocks in the S&P 500 gaining an extraordinary 97%. The sector benefited both
from its rapid growth and from investors' belief that consumers and businesses
will keep spending freely on computer hardware, software, and services. There
was more than a hint of speculation in the air, too, as stocks related to the
burgeoning activity on the Internet skyrocketed.

       Other strong sectors included utilities (+49%), particularly
telecommunications stocks, which are seen as big beneficiaries of the Internet
boom and of rising demand for such services as wireless communications. The
strength of consumer spending--Americans spent nearly every dollar of after-tax
income they earned--boosted the stocks of retailers and other companies in the
consumer-discretionary sector (+37%). Good earnings growth and higher product
prices led to gains for pharmaceutical companies and others in the health-care
sector (+35%).

       The worst-performing sectors were those directly affected by falling
commodity prices: the "other energy" category (-33%) and materials & processing
firms (-2%), such

                                        7

as paper, steel, and chemical makers. Integrated oil companies gained 7% as a
group, largely because merger activity boosted share prices.

       The midyear slide in stocks seemed to be part of a global reevaluation of
risk that affected fixed-income securities as well. Investors grew wary about
the impact of Asia's lingering economic troubles, which slowed activity for U.S.
and European manufacturers and dried up capital flows to emerging markets not
only in Asia but in Latin America.

       The S&P 500 Index fell by nearly 20% over six weeks in July and August
before making its impressive comeback. Small-cap stocks fell by nearly 40%
before they began to recover. Curiously, the rebound occurred even though the
international economic troubles did not disappear and U.S. corporate earnings
were essentially flat. The rise in stock prices, combined with a lack of
earnings growth, pushed up the price/earnings ratio for the S&P 500 to about 32
by fiscal year-end, a level roughly twice its long-term average.

U.S. BOND MARKETS

Interest rates for most fixed-income securities declined on balance during the
fiscal year, falling most steeply for U.S. Treasury securities. Bond prices move
in the opposite direction from interest rates, so Treasuries enjoyed the biggest
price increases. Bonds gener-ally were helped by low inflation--consumer prices
rose by 1.7% from January 1998 to January 1999.

       Treasury securities in particular benefited from the summertime shakeup
in global markets because they are regarded as safe from defaults. Treasury
prices also got a boost from a slight shrinkage in supply due to the federal
government's growing budget surplus. Yields on Treasury securities fell on
balance by approximately 70 to 80 basis points (0.7 to 0.8 percentage point). At
fiscal year-end, Treasury yields ranged from 5.09% for the benchmark 30-year
bond to 4.45% for 3-month T-bills.

       Yields did not fall as far for high-quality corporate and municipal
bonds. Yields for lower-quality bonds increased and their prices declined,
reflecting investors' increased aversion to risk. Mortgage-backed bonds
generally did not benefit from falling rates because investors feared that this
would lead to rapid prepayments by homeowners refinancing their home loans.

INTERNATIONAL STOCK MARKETS

European stocks as a group gained 22.8% in U.S.-dollar terms, with about 5.5
percentage points of the gain due to a fall in the dollar's value versus
European currencies during the fiscal year. However, pickings were slim
elsewhere for U.S. investors venturing abroad. Pacific-region stocks, which are
dominated by recession-wracked Japan, fell by more than 7% in local currencies.
This decline was cushioned by the effect of a weaker dollar, so that for U.S.
investors the decline in Pacific-region stocks amounted to 2.1% for the fiscal
year. Overall, the Morgan Stanley Capital International Europe, Australasia, Far
East (EAFE) Index, a gauge of developed international markets, rose 14.7%.

       Investors in emerging markets were hit by a double whammy: lower stock
prices and a decline in the value of local currencies in relation to the U.S.
dollar. The result was an average decline of 14.2% for emerging markets, even
though several Asian markets (the Philippines, Indonesia, and Hong Kong) began
to rebound from sharp losses that occurred during 1997 and 1998. Latin American
stocks were the big losers, with declines of 53% for Brazil and 24% for Mexico.

The fiscal year ended January 31, 1999, was one that fixed-income investors will
remember for risk--unvarnished, unexpected, and unprecedented risk.

       The fiscal year started peaceably enough. During the first half, the
yield on the 30-year Treasury bond fluctuated within a relatively narrow range
of about 5.6% to 6.0%. The main question for the market was whether the impact
of the "Asian flu" would slow a strong U.S. economy enough to prevent a rise in
inflation. Many Asian economies were suffering sharp downturns due to structural
imbalances. In contrast, the U.S. economy during the first two calendar quarters
of 1998 rose at an annual rate of more than 3.5%, as momentum from domestic
demand easily overcame the drag from reduced exports. The American public was a
major source of this strength, with spending propelled by high employment,
rising incomes, and stock market gains.

       Normally, such rapid expansion would set off alarm bells at the Federal
Reserve--such growth spurts historically have ignited inflation and prompted the
Fed to raise short-term interest rates to slow the economy. Halfway through
1998, however, we seemed to have attained something like economic nirvana--a
strong economy and benign inflation. The gross domestic product (GDP) price
deflator, the broadest measure of inflation, rose at only a 0.9% annual rate.
And through midyear, the Fed was content to sit on the sidelines.

       But this tranquil period was a distant memory by late summer. Even though
Russia's substantial financial problems had become evident, financial markets
were still shocked by the Russian government's bond default in August. The
Russian crisis initiated a wave of fear that enveloped markets across the globe.
The situation was exacerbated by upheavals at some prominent hedge funds, which
were forced to sell securities to repay huge sums they had borrowed to make
investments.

       As fear triumphed over greed, investors seeking quality and liquidity
flocked to U.S. Treasuries and pushed yields on long-term bonds down to levels
not seen in a generation. The yield on the 30-year Treasury bond fell from 5.71%
on July 31 to 4.72% on October 5, its low for the fiscal year. This was one of
the most turbulent periods in decades. If you had predicted in 1990 that
long-term Treasury yields would, within the decade, fall below 5% at the same
time that the unemployment rate was hovering around 4.5% in a strong economy,
most bond portfolio managers would have thought you were crazy.

       Because of the frenzied flight to Treasuries, by late August and early
September the markets in "spread products" (corporate bonds, mortgages, and
asset-backed securities) effectively ceased to function. No new issues were
coming to market and bids were virtually nonexistent. Yields on corporate and
mortgage-backed debt widened dramatically in relation to Treasury yields. The
interest-rate differential

                                        9

<PAGE>   12



that a buyer of an average corporate bond would earn for taking on the credit
risk of a non-Treasury security rose to its highest level since the 1990-1991
Gulf War. August's returns for corporate bonds were the lowest, in relation to
Treasuries, since the leveraged buyout craze of the mid-1980s.

       The Fed responded to this crisis by orchestrating three 25-basis-point
(0.25 percentage point) declines in the target federal funds rate, which is what
banks charge each other for overnight loans, in September, October, and
November. These moves, coupled with less-negative news from emerging market
economies, reduced interest-rate volatility, and during the remainder of the
fiscal year, the 30-year Treasury bond traded in a range of just below 5% to
5.4%, closing the fiscal year at 5.09%.

       After September, liquidity improved substantially in markets for
corporate and mortgage-backed securities, although not approaching anything like
the situation when the fiscal year began. Yields on these instruments slowly
declined in comparison with Treasury yields during November and December, as
buyers realized that financial Armageddon was not at hand. New bond issuance by
corporations picked up, although yield spreads over Treasury yields remained
wider than in the first half of 1998. Spreads tightened even more in January
1999 as an expected burst of new corporate bond issues never materialized and
dealers kept very light inventories of fixed-income securities.

       Despite the turmoil in financial markets, the U.S. economy continued to
hum along. Economic output, adjusted for inflation, advanced from October
through December at a 6.1% annual rate, bringing growth for all of 1998 to 4.3%,
even faster than the 3.8% pace recorded in 1997. The economy had actually
accelerated since the Asian crisis! Inflation remained nearly nonexistent: The
GDP price deflator rose slightly less than 1.0% for 1998, and employment costs
(wages, salaries, and benefits) rose only 3.3%.

FUND REVIEWS

The decline in interest rates during the fiscal year provided a tailwind, in the
form of capital appreciation, to the total returns of six of the nine Vanguard
Bond Funds. As one would expect in such an environment, our intermediate- and
long-term funds, whose share prices are more sensitive to changes in interest
rates, benefited more than their short-term brethren. Because Treasuries were
favored as a safe haven, each of our Treasury funds outperformed its Corporate
counterpart (you'll find details in the Message to Shareholders, beginning on
page 1). Indeed, corporate bonds posted their worst year of the decade in
comparison with the performance of Treasuries. This is exactly the opposite of
what occurred in fiscal 1998, when returns of corporate bonds benefited from the
market's perception that the risk of owning corporates had diminished.

THE RISKS AHEAD

Events of the past 12 months shattered many firmly held beliefs concerning
liquidity, volatility, and relative value within the bond market. While
conditions have improved substantially since the dark days of August and
September, bond investors remain wary of a negative surprise out of Latin
America or some other emerging market. Today's low interest rates do not provide
much protection in the form of income if bond prices fall because the Fed
decides to raise rates to slow an overheated economy or stock market. On the
other hand, competition from overseas companies and low commodity prices should
continue to help restrain inflation, which is the ultimate enemy of the
fixed-income investor because it erodes the future purchasing power of a bond's
income stream. Whether or not U.S. economic strength continues to overpower
weakness from

abroad, it's likely we won't see a year as turbulent as the past one for quite
some time.

       The Vanguard Bond Funds offer investors low-cost investment choices of
varying risk/return characteristics that can be used with a fairly high degree
of precision to structure an overall long-term investment approach. Once such a
plan is in place, staying with it is the best technique for dealing with the
uncertainties of the financial markets.

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

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 fiscal year ended January 31, 1999, yields on
intermediate-term Treasury securities declined by approximately 75 to 90 basis
points (0.75 to 0.90 percentage point), establishing a favorable environment for
bonds. The drop in rates was unusual in that it occurred while the economy was
growing at a rapid clip. Higher-quality bonds outperformed lower-quality ones
because investors demanded higher yields on riskier bonds, which also is unusual
during a period of strong economic growth. Historically, a strong economy leads
to rising interest rates and, therefore, an unfavorable backdrop for the bond
market. This time, however, rates fell because inflation remained low and
because investors were worried about global economic conditions.

       The risk premiums, or incremental yields, offered on corporate bonds
versus riskless U.S. Treasuries rose over the last six months, but these
premiums should narrow if the growing economy produces strong profits.
Currently, the issuance of new corporate bonds--both investment-grade and below
investment-grade--is modest, which alleviates the pressure on the bond market
from new supply. Mortgage-backed securities offer a very enticing yield premium
to reward investors for assuming prepayment risk--the possibility that lower
interest rates will result in unwanted prepayments of principal by homeowners
refinancing their loans. If rates do not drop sharply, and such prepayments
don't materialize, the yield premium on GNMA issues will turn out to be overly
generous. If rates stay in a trading range over the next six months, as we
expect, the yields available on high-yield bonds, long-term corporate bonds, and
GNMA securities offer reasonable value.

GNMA FUND

The fiscal year was eventful for your GNMA Fund. On balance, interest rates fell
sharply generating first fears and then realization of widespread mortgage
refinancing. As a result of the refinancing wave, the fund experienced less
price appreciation than did portfolios that emphasized U.S. Treasury securities.
Even so, your GNMA Fund provided a solid total return, particularly in light of
the low level of inflation. The surge in mortgage prepayments resulted in a
modest decline in income over the course of the year as higher-coupon
investments were in part prepaid and the proceeds were recycled into
lower-coupon securities.

       GNMA securities are attractive now because their yield advantage over
Treasuries is more substantial than it has been in many years.

LONG-TERM CORPORATE FUND

The average maturity of the fund's investments is 19 years, in keeping with its
charter as an investment-grade, long-term corporate bond fund. The fund's
average duration--at 9 years--also is long, making the share price extremely
sensitive to changes in long-term interest rates. Our shareholders should
understand this sensitivity and how it affects their investment. For example, if
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

                                       12

<PAGE>   15



fell over the past 12 months, the fund's return was boosted by capital
appreciation. The Long-Term Corporate Fund has excellent call protection, which
implies that most of our holdings cannot be redeemed by their issuers if rates
decline. This means that the fund's income stream has some protection from
falling rates.

       The major risk for this fund is a rise in long-term interest rates. 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. We hold minimal
cash.

       The second risk always present in this fund is a deterioration in the
creditworthiness of bond issuers. To mitigate this risk, the fund is well
diversified by issuer and industry. More than 80% of assets are invested in
issues rated A or better. The fund does not own below investment-grade bonds,
emerging-market debt, or foreign bonds denominated in non-U.S. currencies. We
generally buy bonds of large, established companies with stable operating
histories.

HIGH-YIELD CORPORATE FUND

The below investment-grade, or high-yield, market acts like a hybrid. Under
some conditions, it follows the direction of the stock market; at other times,
it behaves like the rest of the bond market. When stock prices are very
volatile, as they were at midyear, below investment-grade bonds usually follow
the stock market. When the stock and bond markets are reasonably stable,
high-yield issues tend to be traded like investment-grade bonds.

       Now that fears of an economic slowdown are fading and interest rates are
rising slightly, the high-yield market should perform well in comparison with
other bond sectors. Investors will increase their tolerance for risk so long as
companies' profits remain strong, the issuers' ability to repay their debts
increases, and rating agencies upgrade their outlook for individual companies.

       We remain very selective when examining new issues coming to market. We
are avoiding the smaller, start-up companies and continuing to emphasize the
higher-quality end of the below investment-grade market.

       We conduct in-depth credit research on a company-by-company basis and
emphasize diversification. The fund owns issues representing a broad range of
industries and companies, and our holdings continue to be focused on cash-paying
issues rated B or better. We maintain a modest reserve of Treasury securities in
the event that liquidity is necessary.

both share price and return can fluctuate widely, so an investment in the fund
could lose money.

All of the data on this page represent past performance, which cannot be 
used to predict future returns that may be achieved by the fund. Note, too, 
that both share price and return can fluctuate widely, so an investment in 
the fund could lose money.

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 and agency 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.


                                       25

<PAGE>   28

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
JANUARY 31, 1999

[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, except the Short-Term Federal 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.

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' 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
year ended January 31, 1999, directed brokerage and custodian fee offset
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 year ended January
31, 1999, represented the following percentages of average net assets:

NOTES TO FINANCIAL STATEMENTS (continued)


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.

REPORT OF INDEPENDENT
ACCOUNTANTS

[PHOTO]

To the Shareholders and Trustees of
Vanguard Bond Funds


In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Vanguard GNMA Fund (a separate fund of Vanguard Bond Funds, hereafter referred
to as the "Fund") at January 31, 1999, the results of its operations for the
year then ended, the changes in its net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
period then ended, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at January
31, 1999 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

We have also audited the financial statements of Vanguard Short-Term Treasury
Fund, Vanguard Short-Term Federal Fund, Vanguard Short-Term Corporate Fund,
Vanguard Intermediate-Term Treasury Fund, Vanguard Intermediate-Term Corporate
Fund, Vanguard Long-Term Treasury Fund, Vanguard Long-Term Corporate Fund and
Vanguard High-Yield Corporate Fund at January 31, 1999, and have issued our
report thereon. An insert to this Annual Report containing our report on the
financial statements of these funds is available from Vanguard Bond Funds.

                             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."

                         Walter L. Morgan, founder of
                         Wellington Fund, the nation's
                          oldest balanced mutual fund
                       and forerunner of today's family
                          of some 100 Vanguard funds,
                       celebrated his 100th birthday on
                          July 23, 1998. Mr. Morgan,
                        a true investment pioneer, died
                        six weeks later on September 2.

                               Wellington Fund,
                       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.

FINANCIAL STATEMENTS
JANUARY 31, 1999

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 35 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.

REPORT OF INDEPENDENT
ACCOUNTANTS

[PHOTO]

To the Shareholders and Trustees of
Vanguard Bond Funds

In our opinion, the accompanying statements of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Vanguard Short-Term Treasury Fund, Vanguard Short-Term Federal Fund, Vanguard
Short-Term Corporate Fund, Vanguard Intermediate-Term Treasury Fund, Vanguard
Intermediate-Term Corporate Fund, Vanguard Long-Term Treasury Fund, Vanguard
Long-Term Corporate Fund and Vanguard High-Yield Corporate Fund (separate funds
of Vanguard Bond Funds, hereafter referred to as the "Funds") at January 31,
1999, the results of each of their operations for the year then ended, the
changes in each of their net assets for each of the two years in the period then
ended and the financial highlights for each of the periods indicated, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Funds' management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at January 31, 1999 by
correspondence with the custodians and brokers, provide a reasonable basis for
the opinion expressed above.
