Commander of the U-boat fleet, Supreme Naval Commander, and finally Hitler's successor in the last days of the Third Reich, Grand Admiral Karl Doenitz (18911980) has been condemned as a Nazi and praised as one of the most brilliant and honorable military leaders of the war. His "wolfpack" tactics resulted in a handful of U-boats sinking 14. 5 million tons and nearly deciding the Battle of the Atlantic. Sentenced to ten years at the Nuremberg Trials, Doenitz wrote his memoirs upon his release. In a clear firm style he discusses the planning and execution of the U-boat campaign; the controversial sinking of the Laconia; America's "neutrality" before its entry into the war; the Normandy invasion; the July 1944 bomb plot; his encounters with Raeder, Gring, Speer, Himmler, and Hitler; as well as his own brief tenure as the last F hrer. Doenitz's invaluable work allows the reader to view the war at sea through the periscope's eye.
