The Flower class corvette was one of the most famous & numerous of all escort vessels & the corvette Agassiz is the most representative of the Canadian Flowers which were thrown into the thick of the bitter Atlantic convoy battles of 1941--2. Derived from a whalecatcher hull design & intended as a cheap coastal escort that could be built by non-specialist yards the Flowers were the only class available in large numbers when the submarine war flared up in earnest in 1941. As a result they were used on rigorous ocean convoy duties for which they were barely adequate & their crews suffered greatly in one of the harshest arenas of the second world war. This is a superb description of the ship & her career. The Anatomy of the Ship series aims to provide the finest documentation of individual ships & ship types ever published. What makes the series unique is a complete set of superbly executed line drawings both the conventional type of plan as well as explanatory views with fully descriptive keys. These are supported by technical details & a record of the ships service history.
