Item 4.01 Changes in Registrant's Certifying Accountant.

      On July 12, 2004, PricewaterhouseCoopers LLP ("PwC") notified Trenwick
America Corporation (the "Company") that it resigned as the Company's
independent registered public accounting firm, pending completion of the audits
of the Company's employee benefit plans. PwC completed its services related to
the employee benefit plans on August 30, 2004.

      The reports of PwC on the financial statements for the fiscal years ended
December 31, 2002 and 2001 contained no adverse opinion or disclaimer of opinion
and were not qualified or modified as to uncertainty, audit scope or accounting
principle, except that the report on the financial statements of the Company for
the fiscal year ended December 31, 2002 contained an explanatory paragraph
related to substantial doubt about the Company's ability to continue as a going
concern.

      In connection with its audits for the fiscal years ended December 31, 2002
and 2001 and through August 30, 2004, there have been no disagreements with PwC
on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements if not resolved
to the satisfaction of PwC would have caused them to make reference thereto in
their reports on the financial statements for such years.

      During the fiscal years ended December 31, 2002 and 2001 and through
August 30, 2004, there have been no reportable events (as defined in Regulation
S-K Item 304(a)(1)(v)).

      The Company has requested that PwC furnish it with a letter addressed to
the SEC stating whether or not it agrees with the above statements. A copy of
such letter, dated January 26, 2005, is filed as Exhibit 16 to this Form 8-K.

      The Company is in the process of selecting another independent registered
public accounting firm and a subsequent Form 8-K will be filed following the
engagement of a new firm.

Item 5.02 Departure of Directors or Principal Officers; Election of Directors:
          Appointment of Principal Officers.

      Effective December 23, 2004, and following receipt of approval of the
Connecticut Insurance Commissioner of the Run-Off Plan of the Registrant's
wholly-owned subsidiary, Trenwick America Reinsurance Corporation ("TARCO"), Mr.
Alan L. Hunte resigned as an officer and director of the Registrant and from all
of his positions as an officer and/or director of its affiliates, other than his
positions as an officer and director of The Insurance Corporation of New York
("INSCORP"). Effective December 31, 2004, Mr. Hunte resigned as an officer and
director of INSCORP. Mr. Hunte's resignation was voluntary and did not result
from any disagreement with the Registrant or its affiliates on any matter
relating to the Registrant's operations, policies or practices. Effective on
December 23, 2004, Mr. Hunte was engaged as a consultant by Trenwick America
Services Corporation, a wholly-owned subsidiary of TARCO, to assist in the
run-off of the businesses of TARCO and INSCORP.
