The problem addressed is the extent to which the United States Navy used Ultra, or Special Intelligence, in the campaign against the German U-boats. Information was gathered through published and unpublished sources. Through a chronological approach, United States Navy involvement is traced from entry into the war until its conclusion. Many factors are involved in the final outcome of the war and Ultra is only one. The Battle of the Atlantic was long and gruesome rather than short and spectacular. The United States Navy used Ultra along with technology, tactics, brilliant leadership and courageous men at sea to win the Battle of the Atlantic in World War II. The lessons for the future are clear. If the United States intends to oppose the Soviet submarine force at sea anywhere in the world, then we must maintain the lead in intelligence, tactics and technology. Further, and most importantly, we must strive to regain superiority of forces in those ocean areas where our interests are at stake.

No weapon platform sank more U-boats in the Second World War than the Allied aircraft. Whether it was an American ’plane operating from American escort carriers, US aircraft from Royal Air Force bases, or British aircraft from bases throughout the world, these officers and men became the most decisive factor in turning the tide of the Battle of the Atlantic against the German submarine threat. While the German crews could threaten escort vessels with torpedoes, or avoid them by remaining submerged, their leaders never developed an effective strategy against aircraft. However, the Allied aircraft did not enjoy much early success. British, Canadian and Australian air crews that fought the U-boats from 1939 until 1941 achieved few triumphs. They possessed neither the aircraft nor the bases necessary to deliver consistent lethal attacks against German submarines. In 1941, the Royal Air Force finally began implementing an effective aircraft response when it initiated training on the American-built Consolidated B-24 Liberators. Supported by other types then in service, these four-engine bombers would prove to be decisive. With America’s entry into the war, the United States Navy and the United States Army Air Forces also began employing Liberators against the U-boats so that by mid-1943, the Admiral Karl Dönitz, commander of U-boat forces, withdrew his submarines from the North Atlantic in recognition of the Allied aircraft’s new dominance. From Dönitz’s retreat to the end of the war, Allied aircraft continued to dominate the U-boat battle as it shifted to other areas including the Bay of Biscay. Dönitz eventually ordered his U-boats to remain on the surface and engage Allied aircraft as opposed to submerging. This approach did lead to the demise of some Allied aircraft, but it also resulted in even more U-boat being sunk. Most critically, Dönitz acknowledged with his new policy that he knew of no tactics or weapons that would defend his submarines from Allied aircraft. In the end, it was a matter of choosing whether his submariners would die submerged or die surfaced. Either way, Allied aircraft prevailed. The Allied Air Campaign Against Hitler’s U-Boats is the most comprehensive study ever undertaken of this most crucial battle which helped turn the Battle of the Atlantic irrevocably in favour of the Allies.

This is the second of three volumes covering the U-boat campaign in the Atlantic during the Second World War.??This is the fascinating account, as told from the German perspective, of the Battle of the Atlantic, the longest-running, continuous military campaign in World War II, spanning from 1939 through to Germany's defeat in 1945. At its core was the Allied naval blockade of Germany, which was announced the day after the declaration of war, although it quickly grew to include Germany's counter-blockade. The name "Battle of the Atlantic", was coined by Winston Churchill in 1941 and he famously stated that the U-boats were the only thing that really frightened him. The U-boat war encompassed a campaign that began on the first day of the European war and lasted for six years, involved thousands of ships and stretched over thousands of square miles of ocean, in more than 100 convoy battles and perhaps 1,000 single-ship encounters. In the 68 months of World War II, 2,775 Allied merchant ships were sunk for the loss of 781 U-boats.??This is the story of that massive encounter from the German perspective. Published in three volumes, this work was compiled under the supervision of the U.S Navy Department and the British Admiralty by Fregattenkapitan Gunther Hessler. The author, though without previous experience as a writer, had first hand experience of U-boat warfare having commanded a U-boat in 1940 and 1941. For the remainder of the war he was Staff Officer to the Flag Officer commanding U-boats. He had access to German war diaries and other relevant documents concerning U-boat command, and this work based on these many documents, tells the story entirely from the viewpoint of that command. For this reason this work is essential reading for anyone interested in the history of World War II from primary sources and will be of enduring interest to those engaged in attempting to unravel the true nature of submarine warfare in World War II.

The German attack on merchant shipping in the Second World War, known as the Battle of the Atlantic, was countered partly by code-breaking intelligence known as Ultra. The dramatic revelation of this factor in the middle 1970s resulted in many works giving this as the most important cause of Allied success.

“The tragic final year of Hitler’s once highly effective U-Boat campaign against Allied shipping is graphically and grippingly told here.” —Work Boat World By the end of 1943 the German submarine war on Atlantic convoys was all but defeated, beaten by superior technology, code-breaking and air power. With losses mounting, Karl Dönitz withdrew the wolfpacks, but in a surprise change of strategy, following the D-Day landings in June 1944, he sent his U-boats into coastal waters, closer to home, where they could harass the crucial Allied supply lines to the new European bridgehead. Caught unawares, the British and American navies struggled to cope with a novel predicament—in shallow waters submarines could lie undetectable on the bottom, and given operational freedom, they rarely needed to make signals, neutralizing the Allied advantages of decryption and radio direction-finding. Behind this unpleasant shock lay an even greater threat, of radically new submarine types known to be nearing service. Dönitz saw these as war-winning weapons, and gambled that his inshore campaign would hold up the Allied advance long enough to allow these faster and quieter boats to be deployed in large numbers. This offensive was perhaps Germany’s last chance to turn the tide, yet, surprisingly, such an important story has never been told in detail before. That it did not succeed masks its full significance: in the Cold War that followed, the massive Soviet submarine fleet—built on captured German technology and tactical experience—became a very real menace to Western sea power. In this way, Dönitz’s last gamble set the course of post-war antisubmarine development.

Keeping the Atlantic sea-lanes open was a vital factor in the fight against Nazi Germany. In the battle to protect merchant shipping from the menace of surface raiders and U-boats, Allied resolve and resources were tested to the utmost. The story of the extraordinary measures that were taken to combat the threat, at sea and in the air, has often been told. But there is one crucial element in this prolonged campaign that has still not been fully appreciated the role of code-breaking, in particular the decryption of secret signals transmitted by German Enigma machines. And this is the focus of Roy Nesbits fascinating new account of the Battle of the Atlantic. Using previously unpublished decrypts of U-boat signals, selected from the National Archives, along with historic wartime photographs, he tells the stories of the individual U-boats and describes their fate. Their terse signals reveal, perhaps move vividly than conventional communications could do, the desperate plight of the U-boatmen as they struggled against increasingly effective Allied countermeasures that eventually overwhelmed them.
