Operation Chieftain
Operation Chieftain was a Royal Navy operation during the Second World War. Designed to support Operation Crusader, a decoy convoy, GM 3, was assembled, in an attempt to divert Axis aircraft away from the land battle. Five merchantmen, the oiler ''Brown Ranger'', a sloop, a destroyer, and three corvettes left Gibraltar on 16 November 1941. The freighters were to turn back after dark and return independently while the escort conducted a two day anti-submarine sweep. One corvette had engine trouble, sailed late and sank a German U-boat. Force K contributed to the deception by sailing westwards from Malta to simulate a rendezvous with GM 3, then reversing course overnight. A second diversion force, as Operation Landmark, left Malta early on 21 November, feigning a voyage to Alexandria to escort four merchant ships. For added verisimilitude, the battle squadron at Alexandria sailed as if to meet the ships from Malta. ''B-Dienst The ''B-Dienst'' (german: Beobachtungsdienst, obs ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Crusader
Operation Crusader (18 November – 30 December 1941) was a military operation of the Western Desert Campaign during the Second World War by the British Eighth Army (with Commonwealth, Indian and Allied contingents) against the Axis forces (German and Italian) in North Africa commanded by Erwin Rommel. The operation was intended to bypass Axis defences on the Egyptian–Libyan frontier, defeat the Axis armoured forces and relieve the 1941 Siege of Tobruk. On 18 November 1941, the Eighth Army launched a surprise attack. From 18 to 22 November, the dispersal of British armoured units led to them suffering 530 tank losses and inflicted Axis losses of about 100 tanks. On 23 November, the 5th South African Brigade was destroyed at Sidi Rezegh ( ) but inflicted many German tank casualties. On 24 November Rommel ordered the "dash to the wire" and caused chaos in the British rear echelons but allowed the British armoured forces to recover. On 27 November, the New Zealanders reached t ...

Convoy
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 ...

RFA Brown Ranger (A169)
RFA ''Brown Ranger'' (A169) was a fleet support tanker of the Royal Fleet Auxiliary. During the Second World War she played an important role in the Malta Convoys and in Pacific operations.

Sloop Of War
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term ''sloop-of-war'' encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of World War I and the highly successful of World War II, with anti-aircraft and anti-submarine capability. They performed similar duties to the American destroyer escort class ships, and also performed similar duties to the smaller corvettes of the Royal Navy.

Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvette
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 tons and 2,000 .although recent designs may approach 3,000 tons, having size and capabilities that overlap with smaller frigates. However unlike contemporary frigates, a modern corvette does not have sufficient endurance and seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word ''corf'', meaning a "basket", from the Latin ''corbis''. The rank " corvette captain", equivalent in many navies to " lieutenant commander", derives from the name of this type of ship. The rank is the most junior of three "captain" ranks in s ...

Force K
Force K was the name given to three British Royal Navy groups of ships during the Second World War. The first Force K operated from West Africa in 1939, to intercept commerce raiders. The second Force K was formed in October 1941 at Malta, to operate against convoys sailing from Italy to Libya. Axis air attacks on Malta led to Force K being reduced and on 8 April 1942, the last ship of the force was withdrawn. After a convoy was run to Malta in Operation Stoneage (16–20 November) Force K was re-established against Axis convoys. Force K (1939) The Admiralty suspected that a German pocket battleship was at large and on 1 October 1939 it became certain that a raider was operating in the South Atlantic when the crew of SS ''Clement'' was landed in South America but who mistakenly named the raider as ''Admiral Scheer'' rather than the pocket battleship . On 5 October the Admiralty formed eight groups, Forces F, G, H, I, K, L, M and N to hunt the German cruisers. Searchin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-Dienst
The ''B-Dienst'' (german: Beobachtungsdienst, observation service), also called x''B-Dienst'', X-''B-Dienst'' and χ''B-Dienst'', was a Department of the German Naval Intelligence Service (german: Marinenachrichtendienst, MND III) of the OKM, that dealt with the interception and recording, decoding and analysis of the enemy, in particular British radio communications before and during World War II. B-Dienst worked on cryptanalysis and deciphering (decrypting) of enemy and neutral states' message traffic and security control of ''Kriegsmarine'' key processes and machinery. :"The ultimate goal of all evaluation was recognizing the opponent's goal by pro-active identification of data." B-Dienst was instrumental in moulding Wehrmacht operations during the Battles of Norway and France in spring 1940, primarily due to the cryptanalysis successes it had achieved against early and less secure British Naval cyphers. B-Dienst broke British Naval Combined Cypher No. 3 in October 1941, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malta Convoys
The Malta convoys were Allied supply convoys of the Second World War. The convoys took place during the Siege of Malta in the Mediterranean Theatre. Malta was a base from which British sea and air forces could attack ships carrying supplies from Europe to Italian Libya. Britain fought the Western Desert Campaign against Axis armies in North Africa to keep the Suez Canal and to control Middle Eastern oil. The strategic value of Malta was so great the British risked many merchant vessels and warships to supply the island and the Axis made determined efforts to neutralise the island as an offensive base. The civilian population and the garrison required imports of food, medical supplies, fuel and equipment; the military forces on the island needed reinforcements, ammunition and spare parts. British convoys were escorted to Malta by ships of the Mediterranean Fleet, Force H and aircraft of the Fleet Air Arm and Royal Air Force, during the Battle of the Mediterranean (1940–1 ...

Battle Of The Mediterranean
The Battle of the Mediterranean was the name given to the naval campaign fought in the Mediterranean Sea during World War II, from 10 June 1940 to 2 May 1945. For the most part, the campaign was fought between the Italian Royal Navy ('' Regia Marina''), supported by other Axis naval and air forces, and the British Royal Navy, supported by other Allied naval forces, such as Australia, the Netherlands, Poland and Greece. American naval and air units joined the Allied side in 1942. Each side had three overall objectives in this battle. The first was to attack the supply lines of the other side. The second was to keep open the supply lines to their own armies in North Africa. The third was to destroy the ability of the opposing navy to wage war at sea. Outside of the Pacific theatre, the Mediterranean saw the largest conventional naval warfare actions during the conflict. In particular, Allied forces struggled to supply and retain the key naval and air base of Malta. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Sea Operations Of World War II
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.
