Karl Dönitz was a German admiral who briefly succeeded Adolf Hitler as head of state in May 1945, holding the position until the dissolution of the Flensburg Government following Germany's unconditional surrender to the Allies days later. As Supreme Commander of the Navy beginning in 1943, he played a major role in the naval history of World War II.
The Kriegsmarine was the navy of Nazi Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945.
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. The term is an anglicised version of the German word U-Boot, a shortening of Unterseeboot, though the German term refers to any submarine. Austro-Hungarian Navy submarines were also known as U-boats.
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943.
The submarine film is a subgenre of war film in which the majority of the plot revolves around a submarine below the ocean's surface. Films of this subgenre typically focus on a small but determined crew of submariners battling against enemy submarines or submarine-hunter ships, or against other problems ranging from disputes amongst the crew, threats of mutiny, life-threatening mechanical breakdowns, or the daily difficulties of living on a submarine.
A tonnage war is a military strategy aimed at merchant shipping. The premise is that the enemy has a finite number of ships and a finite capacity to build replacements. The concept was made famous by German Grand Admiral Karl Dönitz, who wrote:
"The shipping of the enemy powers is one great whole. It is therefore in this connection immaterial where a ship is sunk—it must still in the final analysis be replaced by a new ship".
The wolfpack was a convoy attack tactic employed in the Second World War. It was used principally by the U-boats of the Kriegsmarine during the Battle of the Atlantic, and by the submarines of the United States Navy in the Pacific War. The idea of a co-ordinated submarine attack on convoys had been proposed during the First World War but had no success. In the Atlantic during the Second World War the Germans had considerable successes with their wolfpack attacks but were ultimately defeated by the Allies. In the Pacific the American submarine force was able to devastate Japan’s merchant marine, though this was not solely due to the wolfpack tactic. Wolfpacks fell out of use during the Cold War as the role of the submarine changed and as convoys became rare.
Commerce raiding is a form of naval warfare used to destroy or disrupt logistics of the enemy on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them.
Captain Frederic John Walker, was a British Royal Navy officer noted for his exploits during the Second World War. Walker was the most successful anti-submarine warfare commander during the Battle of the Atlantic, and was known popularly as Johnnie Walker.
The Enemy Below is a 1957 American DeLuxe Color war film in CinemaScope about a battle between an American destroyer escort and a German U-boat during World War II. Produced and directed by Dick Powell, the movie stars Robert Mitchum and Curt Jürgens as the American and German commanding officers, respectively. The film was based on the 1956 novel of the same name by Denys Rayner, a British naval officer involved in antisubmarine warfare throughout the Battle of the Atlantic.
HMS Starling, pennant number U66, was a Modified Black Swan-class sloop of the Royal Navy. She was active in the Battle of the Atlantic during the Second World War and was the most successful anti-submarine warfare vessel of the Royal Navy, being credited with the destruction of fourteen U-boats.
HMS Woodpecker, pennant number U08, was a Black Swan-class sloop of the Royal Navy. She was active during the Second World War and was a successful anti-submarine warfare vessel, being credited with the destruction of six U-boats.
Denys Arthur Rayner DSC & Bar, VRD, RNVR was a Royal Navy officer who fought throughout the Battle of the Atlantic. After intensive war service at sea, Rayner became a writer, a farmer, and a successful designer and builder of small sailing craft – his first being the Westcoaster; his most successful being the glass fibre gunter or Bermudian rigged twin keel Westerly 22 from which evolved similar "small ships" able to cross oceans while respecting the expectations, in terms of comfort, safety and cost, of a burgeoning family market keen to get to sea. Before his death in 1967, Rayner had founded, and via his pioneering GRP designs, secured the future expansion of Westerly Marine Construction Ltd – up until the late 1980s, one of Britain's most successful yacht builders.
German submarine U-26 was one of the two Type IA ocean-going U-boats produced by Nazi Germany's Kriegsmarine. Constructed in Bremen, U-26 was commissioned in May 1936. She experienced a short, but successful combat career, sinking eleven ships.
Black May refers to a period in the Battle of the Atlantic campaign during World War II, when the German U-boat arm (U-Bootwaffe) suffered high casualties with fewer Allied ships sunk; it is considered a turning point in the Battle of the Atlantic.
The SC convoys were a series of North Atlantic convoys that ran during the battle of the Atlantic during World War II.
The early phase of the Battle of the Atlantic during which German Navy U-boats enjoyed significant success against the British Royal Navy and its Allies was referred to by U-boat crews as "the Happy Time", and later the First Happy Time, after a second successful period was encountered.
BETASOM was a submarine base established at Bordeaux, France by the Regia Marina Italiana during World War II. From this base, Italian submarines participated in the Battle of the Atlantic from 1940 to 1943 as part of the Axis anti-shipping campaign against the Allies.
Rösing's wolfpack was a formation of Nazi Germany's Kriegsmarine in World War II, a "wolfpack" of U-boats that operated during the early stages of the Battle of the Atlantic.
