ITEM 8.01  OTHER EVENTS

Hamilton,  Bermuda  (May 1, 2007):  The Joint  Liquidators  of  Trenwick  Group
Limited (the Company) are providing holders of the Company's Common Shares, par
value $0.10 per share (the "Common Shares") with a status report of the affairs
of the Company by way of filing the report attached hereto on this Form 8-K.

The Joint  Liquidators  previously  notified  holders of Common Shares of their
intention  to limit the  Company's  public  announcements  to  material  events
relating to the Company's winding-up (liquidation)  proceedings in Bermuda. The
Joint  Liquidators also notified holders of Common Shares of their intention 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, and,  subject to the
resources  available to the Company,  to report on the status of the  Company's
affairs at least  annually.  The report  being filed on this Form 8-K is one of
such  reports.  The Joint  Liquidators  previously  notified  holders of Common
Shares that reports on the Company's affairs  (including the report being filed
herewith)  will not be mailed to  holders  of Common  Shares,  unless the Joint
Liquidators are required to do so or unless the Joint 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.
