This book is for u-boat nuts and submariners. It is a "direct wartime translation by the U.S. Navy" from the 1943 SECRET edition issued to U-Boat commander by the Oberkommando der Kriegsmarine. Oddly, it is dedicated to Kapitaenleutnant Werner Henke, bearer of the Knight's Cross to The Iron Cross With Oak Leaves.He was the C.O. of U 515. He was killed while attempting to escape from the interrogation center at Fort Hunt and is buried at Fort Meade. There are photos of the inside of U-505, now up on blocks near the Museum of Science and Industry in Chicago.[I well remember when a fellow naval officer whispered to me, outside a P.O.W. cage near Brest, France , "they got the 505."] It was a great maritime triumph.
The book is paragraph after paragraph of such instructions as "Carrying Out the Night Surface Attack", and "How To Deal With Convoys." The photographs which have been added to the edition at hand (1989) add significantly to what could be an interesting but pretty dry instruction, manual.
