During World War II, the Royal Canadian Navy expanded from a tiny service of ten ships to become the third largest Allied navy. The RCN's primary role was convoy escort; its contribution to victory in the Atlantic has been detailed in several studies, but there has long been a need for an illustrated history. The Canadian Naval Memorial Trust commissioned "In Peril on the Sea" to commemorate in May 2003 the 60th anniversary of the high point of the Battle of the Atlantic. As well as the text by Donald E Graves, the book includes personal accounts of 65 eyewitnesses -- British, Canadian, German, among them sailors, submariners and merchant seamen -- who participated in the Second World Wars longest operation. The book contains nearly 200 photographs, drawings, maps, diagrams and ship profiles which bring to life with compelling immediacy the grim but courageous struggle to preserve the sea lanes of freedom between 1939 and 1945.
