Book Description
Otto Kretschmer was only in combat from September 1939 until March 1941 but was Germany's highest-scoring U-boat commander sinking 47 ships totaling 274,333 tons. This definitive work details his personal story and the political backdrop from his earliest days. Aged 17 he spent 8 months studying literature at Exeter University where he learned to speak English fluently. The following year, on 1 April 1930, he enlisted as an officer candidate in the Weimar Republic's small navy. After completing his officer training and time on the training ship Niobe he served aboard the light cruiser Emden. In December 1934 he was transferred to the light cruiser Köln, then in January 1936 made the move to the fledgling U-boat service. His first operational posting was to the 2nd U-Flotilla’s Type VII U35 where he almost being drowned during training in the Baltic Sea! During the Spanish Civil War, he was involved in several patrols as part of the international nonintervention force. He was finally given command of U23, a post which he held until April 1940. He had already sunk 8 ships including the destroyer HMS Daring east of Pentland Firth on 18 February 1940. He demonstrated a cool approach to combat: his mantra ‘one torpedo for one ship’ proved that the best way for his boat to succeed against a convoy was to remain surfaced as much as possible, penetrating the convoy and using the boat’s high speed and small silhouette to avoid retaliation. His nickname ‘Silent Otto’ referred to his ability to remain undetected and his reluctance to provide the regular radio reports required by Dönitz: he had guessed that the Allies had broken German codes. Alongside his military skill was a character that remained rooted in the traditions of the Prussian military. While other U-boat commanders and crew returned from patrol with beards and a relaxed demeanor, U99 always returned with all men clean-shaven and paraded on deck. In the Bowmanville POW camp he organized a 2-way radio link to the German Naval High Command and planned a mass breakout with a U-boat rendezvous arranged. He was also instrumental in the ‘Battle of Bowmanville’ that lasted for 3 days in October 1942. His antics behind the wire became the inspiration for the 1970 film ‘The McKenzie Break’. Postwar he answered the call for volunteers upon the establishment of the Bundesmarine. He retired from the rank of Flotillenadmiral in 1970. He suffered a fall celebrating his 50th wedding anniversary aboard a boat and died two days later at the age of 86.

U-Boat Ace
Author: Jordan Vause
Publisher: Naval Institute Press
ISBN: 1612513808
Category : History
Languages : en
Pages : 224
Book Description
An exceptional figure in the history of the German Navy, Wolfgang Luth was one of only seven men in the Wehrmacht to win Germany's highest combat decoration, the Knight's Cross with Oak Leaves, Swords, and Diamonds. At one time or another he operated in almost every theater of the undersea war, from Norway to the Indian Ocean, and became the second most successful German U-boat ace in World War II, sinking more than 220,000 tons of merchant shipping. A master in the art of military leadership, Luth was the youngest man to be appointed to the rank of captain and the youngest to become commandant of the German Naval Academy. Nevertheless, his accomplishments were overshadowed by those of other great aces, such as Prien, Kretschmer, and Topp. The publication of this book in hardcover in 1990 marked the first comprehensive study of Luth's life. Jordan Vause corrects the long neglect by providing an entertaining and authoritative biography that places the ace in the context of the war at sea. This new paperback edition includes corrections and additional information collected by the author over the past decade.

ISBN: 9781841450537
Category : World War, 1939-1945
Languages : en
Pages : 0
Book Description
The Royal Oak was one of the mightiest battleships of the British Navy although, prior to the start of the Second World War, it had been scheduled for retirement. Nonetheless, when it was sent to the bottom of the sea on 14 October 1939 the shock was felt thoughout Britain. How could it be vulnerable to attack when it lay inside the great naval base of Skapa Flow, ringed by defences that were believed, by the Royal navy, to be impregnable? U-47, commanded by Gunther Prien, had found a way though the maze to the heart of the anchorage where the Royal Oak lay. Suddenly two torpedoes blew the mighty battleship apart and it capsized with the loss of over 800 men. In the mayhem that followed, Prien and his crew escaped unnoticed. Gunther Prien went on to become, until his death in May 1941, the leading U-boat commander and was awarded Germany's highest decoration, the Knight's Cross - with the Oakleaves being awarded posthumously. U-Boat Commander is Prien's own account of his early life, his training for U-boat command in the early years of Hitler's Third Reich up to the sinking of the Royal Oak.

George Placzek: A Nuclear Physicist's Odyssey
Author: Ales Gottvald
Publisher: World Scientific
ISBN: 9813236930
Category : Science
Languages : en
Pages : 395
Book Description
This book presents the first detailed biography of George Placzek — an outstanding physicist, a participant in the Manhattan Project who stood at the very inception of nuclear physics and the subsequent development of the nuclear bomb in the course of the WWII. In the 1930s, George Placzek was known as an adventurous person with a sharp sense of humor, a tireless generator of novel physics ideas which he generously shared with his colleagues. Born in Brno (now Czech Republic) into a wealthy Jewish family, he lost all his relatives to Holocaust, casting a tragic shadow on his life.Placzek's scientific career began in the late 1920s when the quantum revolution was almost over, but nuclear physics was still at its infancy. He established personal and scientific relations with the creators of quantum mechanics, such as Heisenberg in Leipzig and Niels Bohr in Copenhagen. In Rome, he worked with Fermi, and in Copenhagen he became a part of Bohr's nuclear physics team which dominated nuclear theory at that time. The scope of Placzek's pilgrimage around world physics centers in the 1930s was unique among his colleagues. In January 1939, George Placzek managed to emigrate from Europe to the US, and became a part of the British Mission within the Manhattan Project. His physical insights were instrumental in advancing from the basic discoveries on nuclear chain reactions to the Trinity experiment, Hiroshima and Nagasaki.This book is a unique compilation of a large number of previously unknown and unpublished documents from private and university archives, police reports, etc. Placzek's correspondence with the leadership of the Hebrew University in 1934, the 1937 NKVD interrogation files of Konrad Weisselberg, recollections of Ella Andriesse as well as the Zurich Police report of 1956 detailing the circumstances of Placzek's death in a Zurich hotel are illuminating as they shed light on poorly known pages of his life.

Building for Battle: U-Boat Pens of the Atlantic Battle
Author: Philip Kaplan
Publisher: Pen and Sword
ISBN: 152670546X
Category : History
Languages : en
Pages : 219
Book Description
The only thing that ever really frightened me during the war was the U-boat peril - Prime Minister Winston Churchill. Churchill, as a former First Lord of the Admiralty, was well versed in the importance of Britain protecting itself at sea. In the opening years of the Second World War, Germanys U-boat (submarine) fleet was tasked with attacking and destroying the supply ships that Britain depended upon for its survival.The U-boats were under the command of Grand Admiral Karl Doenitz who, for much of the war, effectively guided that strategy. There was a very real possibility that the British people would starve if the U-boats succeeded in their campaign. When France fell to the German forces in 1940, Hitlers Ubootwaffe gained a significant asset in five important ports along the Brittany coast - Brest, Lorient, St. Nazaire, La Palace and Bordeaux. The use of these ports put Germanys submarine force hundreds of miles closer to the action in the North Atlantic, the routes of the Allied supply convoys which were operating mainly between Halifax, Nova Scotia and various English port cities. This afforded the U-boats several more days at sea on their deadly patrols than was possible while they had been based in Germany and German-occupied Norway.In this new publication from Philip Kaplan, the massive bunkers or pens constructed in Brittany by the laborers of the German Organisation Todt are revisited. These giant structures, some of which sheltered more than a dozen submarines at a time, still exist because they were built with concrete ceilings more than three meters thick. With equally impressive supporting walls, they suffered relatively little damage in the wartime bombing raids of the Royal Air Force and the US Eighth Army Air Force. Illustrated with more than 150 rare and compelling photo images, this book is a richly rewarding journey back across time to some of the most intriguing and electrifying sites from the war years. The story of the pen shelters and their part in that war is both fascinating and enduring.

History of the U-Boot
Author: Kittel & Graf
Publisher: Edizioni R.E.I.
ISBN: 237297176X
Category : History
Languages : en
Pages : 170
Book Description
U-Boot is the German term to refer broadly to submarines, and is short for Unterseeboot, literally "submarine boat". The objectives of the U-boat campaigns in both wars were the convoys carrying supplies from the US to Europe. The term U-Boot, followed by a number, such as U-Boot 47 indicates a specific vessel, while U-Boot Type II a particular class, the only U-boats that can be considered true submarines, and submarines, are those that belong to the Type XXI and Type XXIII. During the Second World War, the attacks of the U-boats were the main component of the Battle of the North Eastern, which lasted until the end of the war. During the early stages of the war and immediately after the entry of the United States, the U-boats were extremely effective in the destruction of merchant allies. Improvements in tactical convoys, sonar, the depth charges, the deciphering of the Enigma code used by the Germans and the range of escort aircraft served to turn the fate against the U-boats. At the end of the U-boat fleet suffered extremely heavy losses, losing 789 units (three British submarines captured) of 1157 (of which 25 Allied captured) and about 30,000 sailors on a total of 50.000. The German U-boats and Japanese submarines and Italian sank around 2,828 Allied ships, for a total of about 15 million tons. Between 1939 and 1942 the U-boats also bombed the oil fields of Florida and Americans of many coastal areas causing extensive damage; when the British found a way to decipher Enigma allies were able to predict the movements, yet the Germans did not interrupt the use of U-boats in the Atlantic. During World War II, the Kriegsmarine (German Navy) produced different types of U-boats, as the technology improved. In this volume are indicated in detail the characteristics of all the classes of U-Boot, from Type I to Type XXIII, in addition to the history of the U-boats that made the protagonists during the Second World War.
