ITEM 8.01    OTHER EVENTS

Hamilton, Bermuda (March 31, 2005): The Joint Provisional Liquidators of
Trenwick Group Limited (the Company) have mailed to holders of record of the
Company's common shares, par value $0.10 per share (the "Common Shares"), a
letter dated March 30, 2005 providing holders of Common Shares with a status
report of the affairs of the Company.

The letter also notifies holders of Common Stock of the Joint Provisional
Liquidators' intention to limit the Company's public announcements in the future
to material events relating to the Company's winding-up (liquidation)
proceedings in Bermuda. The Joint Provisional Liquidators intend to disclose any
such event to the public by filing with the US Securities and Exchange
Commission (SEC) a current report on Form 8-K. Subject to the resources
available to the Company, the Joint Provisional Liquidators intend to report on
the status of the Company's affairs at least annually. Reports on the Company's
affairs will not be mailed to holders of Common Shares in the future, unless the
Joint Provisional Liquidators are required to do so or unless the Joint
Provisional Liquidators believe, in their sole judgment, that it is in the best
interest of the Company's stakeholders.

The Company's current reports on Form 8-K are available free of charge at the
SEC's website www.sec.gov.
