List Of Wolfpacks Of World War II
Wolfpack (naval tactic), Wolfpacks (german: U-Boot-Gruppe) were employed by Nazi Germany's Kriegsmarine during World War II against Allied and neutral shipping. Outbreak of War From the outbreak of war until mid-1940 there were various groups of U-boats engaged in collective patrols. With the exception of experimental Hartmann's wolfpack in 1939, the first recognised wolfpack was led by ''KrvKpt'' Günther Prien in June 1940. Invasion of Norway & Denmark In preparation for the impending invasion of Norway and Denmark, in early April 1940, 31 U-boats were ready for operations between England and Norway. On 6 April, the codeword "Operationsbefehl Hartmut, Hartmut" was transmitted and German submarines began their designated operations.

Wolfpack (naval Tactic)
The wolfpack was a convoy attack tactic employed in the Second World War. It was used principally by the U-boats of the 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. World War I During the (German war on trade) Allied ships travelled independently prior to the introduction of the convoy system and were vulnerable to attacks by U-boats operating as 'lone wolves'. By gathering up merchant ships into co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convoy US 3
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas. Naval convoys Age of Sail Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century. The use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval convoy tactics had been developed to ward off pirates and privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer coul ...

SL Convoys
SL convoys were a numbered series of North Atlantic trade convoys during the Second World War. Merchant ships carrying commodities bound to the British Isles from South America, Africa, and the Indian Ocean traveled independently to Freetown, Sierra Leone to be convoyed for the last leg of their voyage to Liverpool. History On the basis of World War I experience, SL convoys were one of four trade convoy routes organized at the beginning of the Battle of the Atlantic. The other routes were HX convoys from North America, HG convoys from the Mediterranean, and a short-lived series of HN convoys from Norway. Eight ships sailed as convoy SL 1 sailed on 14 September 1939 and three faster ships sailed six days later as a faster section -- sometimes designated SL(F) 1 or SL 1(F). The slower convoy was sometimes similarly suffixed with an (S). Early convoys were usually accompanied by an armed merchant cruiser or one of the South Atlantic Station cruisers based at Freetown; but no an ...

Rösing's Wolfpack
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. Background Rösing's wolfpack was an early attempt by the '' Kriegsmarine'' during World War II in its wolfpack tactic against Allied convoys. Its operations were in June 1940, at the beginning of the "Happy Time", when the U-boat Arm renewed its offensive in the Atlantic campaign. The name "Rösing" was unofficial, taken from that of its commander, Hans-Rudolf Rösing. Unlike later packs which had specific code names this formation was left without an official designation. In June 1940 U-boat Command (BdU) received intelligence that a large troop convoy would be passing through the mid-Atlantic to Britain. The convoy, designated US 3, would comprise seven troopships, including and would be transporting some 25,000 Australian and New Zealand troops. It was decided to form a patrol line off the coa ...
