EXHIBIT 99.1

      NEW YORK, NY, August 6, 2003 -- Net earnings of Alleghany Corporation
(NYSE-Y) in the second quarter of 2003 were $6.0 million, or approximately $0.81
per share of common stock, compared with net earnings of $8.9 million, or
approximately $1.19 per share of common stock, in the second quarter of 2002,
John J. Burns, Jr., President and chief executive officer of Alleghany,
announced today. Net earnings include net gains on investment transactions after
taxes in the second quarter of 2003 of $1.0 million, or $0.14 per share,
compared with $2.8 million, or $0.38 per share, in the corresponding 2002
period. In the first six months of 2003, Alleghany's net earnings were $13.7
million, or approximately $1.85 per share, compared with net earnings of $34.7
million, or $4.64 per share, in the first six months of 2002. The 2003 six-month
results include net gains on investment transactions after taxes of $3.1
million, or approximately $0.42 per share, compared with $25.3 million, or
approximately $3.39 per share, in the corresponding 2002 period.

      Alleghany common stockholders' equity per share at June 30, 2003 was
$193.07 per share, an increase from common stockholders' equity per share of
$185.85 as of March 31, 2003 (both as adjusted for the stock dividend declared
in March 2003).

      Alleghany Insurance Holdings, a holding company for Alleghany's insurance
operations, consisting principally of Capitol Transamerica Corporation, recorded
pre-tax earnings of $2.7 million on revenues of $38.3 million in the second
quarter of 2003, compared with a pre-tax loss of $2.1 million on revenues of
$33.2 million in the 2002 second quarter. Alleghany Insurance Holdings recorded
pre-tax investment income of $4.8 million and realized pre-tax net losses on
investment transactions of $0.03 million in the 2003 second quarter, compared
with pre-tax investment income of $3.6 million and realized pre-tax net losses
on investment transactions of $1.0 million in the corresponding 2002 period.
Alleghany Insurance Holdings' 2003 pre-tax investment income reflects a larger
invested asset base, principally due to capital contributions by Alleghany. On
July 1, 2003, Alleghany Insurance Holdings completed the acquisition of Royal
Specialty Underwriting, Inc., as discussed below.

      World Minerals recorded pre-tax earnings of $6.5 million in the 2003
second quarter, compared with pre-tax earnings of $7.7 million in the 2002
second quarter, primarily reflecting lower margins due to competitive pricing
pressures and increased labor and benefit costs. Revenues in the 2003 second
quarter were $69.0 million, compared with $66.9 million in the second quarter of
2002, reflecting the favorable impact of the strengthening of the Euro and the
pound sterling against the U.S. dollar.

      Heads & Threads recorded a pre-tax loss of $1.8 million in the 2003 second
quarter, compared with pre-tax earnings of $0.6 million in the corresponding
2002 period, primarily reflecting a $1.1 million charge in connection with
changes in senior management and the relocation of Heads & Threads' corporate
offices from New Jersey to Chicago, competitive pricing pressures and higher
material costs due to increases in the cost of steel from China. Revenues in the
2003 second quarter were $27.3 million, compared with $29.0 million in the 2002
second quarter, primarily reflecting reduced demand in the U.S. economy.

*Operating income represents net earnings per share less the net gain or loss on
investment transactions taxed at the federal income tax rate.

      As of June 30, 2003 Alleghany beneficially owned approximately 16.0
million shares, or 4.3 percent, of the outstanding common stock of Burlington
Northern Santa Fe Corporation, which had an aggregate market value on that date
of approximately $455.0 million, or $28.44 per share, compared with a market
value on March 31, 2003 of $398.4 million, or $24.90 per share. The aggregate
cost of such shares is approximately $181.8 million, or $11.36 per share.

      Alleghany has previously announced that it may purchase shares of its
common stock in open market transactions from time to time. In the second
quarter of 2003, Alleghany did not purchase any shares of its common stock. As
of June 30, 2003, Alleghany had 7,458,192 shares of common stock outstanding
(which includes the stock dividend declared in March 2003).

      As previously announced, on July 1, 2003, Alleghany Insurance Holdings
completed the acquisition of Royal Specialty Underwriting, Inc. ("RSUI") from
Royal & Sun Alliance Insurance Group for approximately $115.0 million. In
addition to RSUI, Alleghany Insurance Holdings acquired renewal rights to the
ongoing business underwritten by RSUI for insurance affiliates of Royal & Sun
Alliance and the related net unearned premium reserve portfolio of approximately
$320.0 million. The transaction excluded loss reserves associated with business
previously underwritten by RSUI for insurance affiliates of Royal & Sun
Alliance.

      RSUI underwrites specialty insurance coverages through wholesale brokers
and producers. Premiums related to RSUI underwritten business are approximately
evenly split between the admitted and non-admitted insurance markets, with
approximately 68.0% of total premiums written for specialty property coverages.
Insurance policies underwritten by RSUI for insurance affiliates of Royal & Sun
Alliance accounted for gross written premiums of $1,205.0 million and net
written premiums of $515.0 million for the year ended December 31, 2002 and
gross written premiums of $359.8 million and net written premiums of $162.0
million for the first quarter of 2003.

      To support future business to be underwritten by RSUI, Alleghany Insurance
Holdings acquired Underwriters Reinsurance Company ("URC"), an insurance company
admitted in 50 states and capitalized it at approximately $500.0 million. In
connection with the acquisition, the seller contractually retained all of the
liabilities of URC that existed at the time of the sale. The name of URC will be
changed to RSUI Indemnity Company and the name of RSUI will be changed to
Resurgens Specialty Underwriting, Inc. A.M. Best Co. has assigned a financial
strength rating of A (Excellent) to URC.

      URC expects to acquire Landmark American Insurance Company ("Landmark"), a
surplus lines insurance company, from Royal & Sun Alliance during the third
quarter to write non-admitted or surplus business underwritten by RSUI. Pending
satisfaction of regulatory rate and form filings by URC and the acquisition of
Landmark, RSUI is continuing to underwrite on policies issued by insurance
affiliates of Royal & Sun Alliance. All such policies are fully reinsured by
URC.

      This press release contains forward-looking statements with respect to the
anticipated effects of the RSUI transaction. Actual results of the transaction
could be significantly different. Factors that could affect results include
those set forth in filings made by the Company with the Securities and Exchange
Commission. Although forward-looking statements help to provide complete
information about future prospects, readers should keep in mind that
forward-looking statements are much less reliable than historical information.
