Convoy ON 166
Convoy ON 166 was the 166th of the numbered ON series of merchant ship convoys Outbound from the British Isles to North America. Sixty-three ships departed Liverpool 11 February 1943 and were met the following day by Mid-Ocean Escort Force Group A-3 consisting of the s and and the s , , , and . The convoy suffered losses before arriving at New York City, US. Background As western Atlantic coastal convoys brought an end to the Germans' " second happy time", Admiral Karl Dönitz, the '' Befehlshaber der U-Boote'' (''BdU'') or commander in chief of U-Boats, shifted focus to the mid-Atlantic to avoid aircraft patrols. Although convoy routing was less predictable in the mid-ocean, Dönitz anticipated that the increased numbers of U-boats being produced would be able to effectively search for convoys with the advantage of intelligence gained through '' B-Dienst'' decryption of British Naval Cypher Number 3. However, only 20 percent of the 180 trans-Atlantic convoys sailing from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Convoy PQ 17
Convoy PQ 17 was an Allied Arctic convoy during the Second World War. On 27 June 1942, the ships sailed from Hvalfjörður, Iceland, for the port of Arkhangelsk in the Soviet Union. The convoy was located by German forces on 1 July, shadowed and attacked. The First Sea Lord, Admiral Sir Dudley Pound, acting on information that German ships, including , were moving to intercept, ordered the covering force, based on the Allied battleships and away from the convoy and told the convoy to scatter. Because of vacillation by ''Oberkommando der Wehrmacht'' (OKW, German armed forces high command), the ''Tirpitz'' raid never materialised. The convoy was the first large joint Anglo-American naval operation under British command; in Churchill's view this encouraged a more careful approach to fleet movements. As the close escort and the covering cruiser forces withdrew westwards to intercept the German raiders, the merchant ships were left without escorts. The freighters were attacked ...

Convoy ON 67
Convoy ON 67 was a trade convoy of merchant ships during the Second World War. It was the 67th of the numbered series of ON convoys Outbound from the British Isles to North America. The ships departed from Liverpool on 14 February 1942 with convoy rescue ship ''Toward'', and were escorted to the Mid-Ocean Meeting Point by escort group B4. The escort group On 19 February the US naval task unit TU 4.1.5 assumed escort responsibility with s and , s and and the Canadian .Abbazia (September 1975) p. 50 ''Edison''s commanding officer, Commander Albert C. Murdaugh, USN, was the senior officer of the escort group. The escort group had never operated together before. ''Bernadou'' had been modified for long range escort work by replacing the fourth boiler and stack with an extra fuel tank. ''Nicholson'' had the only functional radar, though the merchant ship ''Toward'' could provide support with its High-frequency direction finding (HF/DF) set. ''Lea'' carried a British ASV airc ...

Convoy PQ 18
Convoy PQ 18 (2–21 September 1942) was an Arctic convoy of forty Allied freighters from Scotland and Iceland to Arkhangelsk in the Soviet Union during the Second World War. The convoy departed Loch Ewe, Scotland on 2 September 1942, rendezvoused with more ships and escorts at Iceland and arrived at Arkhangelsk on 21 September. An exceptionally large number of escorts were provided by the Royal Navy in Operation EV, including the first escort carrier to accompany an Arctic convoy. Detailed information on German intentions was provided by the code breakers at Bletchley Park and elsewhere, through Ultra signals decrypts and eavesdropping on ''Luftwaffe'' wireless communications. The German code-breakers read some British signals and the ''Luftwaffe'' used the lull in convoys after Convoy PQ 17 (27 June – 10 July) to prepare a maximum effort with the ''Kriegsmarine''. From 12 to 21 September Convoy PQ 18 was attacked by bombers, torpedo-bombers, U-boats and mines, which sank thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Empire Ships (U–Z)
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of ''The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

Convoy HX 79
HX 79 was an Allied convoy in the North Atlantic of the HX series, which sailed east from Halifax, Nova Scotia. The convoy took place during the Battle of the Atlantic in the Second World War. One ship dropped out and returned to port, leaving 49 to cross the Atlantic for Liverpool. Two armed merchant cruisers and a submarine escorted the convoy to protect it from German commerce raiders. The oceanic escorts detached from the convoy at noon on 18 October, in the Western Approaches, where Convoy SC 7 had been attacked by a Wolfpack on the night of 18/19 October, which sank many ships and scattered the survivors. The Admiralty sent the ten ships and a submarine escorting Convoy OB 229 to defend Convoy HX 79, which arrived from to noon on 19 October. During the night of 19/20 October, U-boats attacked the convoy and sank twelve ships. The convoy escorts were inexperienced and not trained in common anti-submarine tactics, the four corvettes were new and crewed with inexperi ...

Convoy HX 229
During the Battle of the Atlantic, British merchant shipping was formed into convoys for protection against German submarine attack. In March 1943 convoys HX 229 and SC 122 were the focus of the largest convoy battle of the Second World War. ''Kriegsmarine'' tactics against convoys employed wolfpack tactics in nearly simultaneous surface attacks at night. Patrolling aircraft restricted the ability of submarines to converge on convoys during daylight. The North Atlantic winters offered the longest periods of darkness to conceal surfaced submarine operations. The winter of 1942–43 saw the largest number of submarines deployed to the mid-Atlantic before comprehensive anti-submarine aircraft patrols could be extended into that area. During March, there was a series of fierce convoy battles which became, for the Allies, the crisis point of the whole campaign. One hundred merchant ships in trade convoys HX 229 and SC 122 encountered three wolfpacks of 38 submarines in a single spraw ...
