From an amazing collection of photographs, found in the underwater base of the U-boats of Brest at the end of the war, and remained hidden until recently in a shoebox, this unique book traces the complete history a U-boat missions during the summer of 1942. The submarine in question, U-564, features the famous pattern “three black cats” of “Teddu Suhren” which, with Prien and Kretschmer, was one of the great commanders of U-boats in the Battle of the Atlantic.

This remarkable book provides a unique perspective on both the day by day life on a U-boat and the intricate workings of the German Navy. Through the successes and trials of U-564, the reader is taken through this huge naval battlefield; perhaps one of the most important theaters of the Second World War.
