This book was commissioned by the Canadian Naval Memorial Trust to commemorate the 60th anniversary of the Battle of the Atlantic. Written and complied by Donald E. Graves, it includes not only the author's text but many excerpts from the recollections of those who took part... Canadian, German, sailors, civilians. The book is generously illustrated with photographs as well as drawing, maps and diagrams that explain the intricacies of anti-submarine warfare in World War II.
