Convoy HX 112
HX 112 was a North Atlantic convoy of the HX series which ran during the battle of the Atlantic in the Second World War. It saw the loss of U-boats commanded by two of the Kriegsmarine's most celebrated commanders and propaganda heroes: under Otto Kretschmer (POW), and under Joachim Schepke (KIA). Prelude HX 112 was an east-bound convoy of ships which sailed from Halifax on 1 March 1941, making for Liverpool with war materials. Many of the ships in HX 112 were tankers carrying fuel oil to Britain. It was escorted by 5th Escort Group which consisted of two destroyers, and and two corvettes, and was led by Commander Donald Macintyre of HMS ''Walker''. 5th Escort Group was reinforced on this occasion by an additional two destroyers, in view of the importance of the cargo, and met the convoy as it entered the Western Approaches. On 15 March 1941 HX 112 was sighted by commanded by Fritz-Julius Lemp, who sent in a sighting report and commenced shadowing the convoy. He ...

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 vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million 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. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City Of Halifax
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

S-class Destroyer (1917)
The S class (initially known as the Modified ''Trenchant'' classMarch, ''op. cit.'' p.215.) was a class of 67 destroyers ordered for the Royal Navy in 1917 under the 11th and 12th Emergency War Programmes. They saw active service in the last months of the First World War and in the Russian and Irish Civil Wars during the early 1920s. Most were relegated to the reserve by the mid-1920s and subsequently scrapped under the terms of the London Naval Treaty. Eleven survivors saw much action during the Second World War. Background In early 1917, the First World War had been going on for two and a half years. Despite the disappointing outcome of the Battle of Jutland the previous year, the British Grand Fleet, consisting of battleships, cruisers, and destroyers and based in northern Scotland, was successfully confining the German surface navy to the German Bight, while enforcing a blockade of German maritime trade with the wider world. In southern North Sea, the Harwich Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armed Merchantman
An armed merchantman is a merchant ship equipped with guns, usually for defensive purposes, either by design or after the fact. In the days of sail, piracy and privateers, many merchantmen would be routinely armed, especially those engaging in long distance and high value trade. In more modern times, auxiliary cruisers were used offensively as merchant raiders to disrupt trade chiefly during both World War I and World War II, particularly by Germany. While armed merchantmen are clearly inferior to purpose-built warships, sometimes they have scored successes in combat against them. Examples include East Indiamen mimicking ships of the line and chasing off regular French warships in the Battle of Pulo Aura in 1804, and the sinking the Australian light cruiser in their battle in 1941, although ''Kormoran'' was also destroyed and had to be scuttled. Pre-20th century East Indiamen of various European countries were heavily armed for their long journeys to the Far East. In parti ...

Heavy Cruiser
The heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in caliber, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser designs of the 1900s and 1910s, rather than the armored cruisers of the years before 1905. When the armored cruiser was supplanted by the battlecruiser, an intermediate ship type between this and the light cruiser was found to be needed—one larger and more powerful than the light cruisers of a potential enemy but not as large and expensive as the battlecruiser so as to be built in sufficient numbers to protect merchant ships and serve in a number of combat theaters.

Convoy SC 48
SC 48 was a North Atlantic convoy of the SC series which ran during the battle of the Atlantic in World War II. It was notable for being the occasion of the ''Kearny'' incident, which brought the United States one step closer to war with Germany. Prelude SC 48 was an east-bound convoy of 52 ships, carrying war materials and sailed from Sydney, Cape Breton on 5 October 1941 bound for Liverpool. It was under the command of Commodore HM Sanders in the MV ''Castalia''. It was escorted by a Canadian escort group consisting of the (Lt Cdr SW Davis as Senior Officer Escort), and seven s; , , , , , and the Free French Naval Forces' ''Mimosa''. On 9 October the group ''Mordbrenner'' was formed in the area south of Iceland near the Mid-Ocean Meeting Point. This was the point at which North Atlantic convoys were handed over between the Ocean and the Western Approaches escorts at this stage of the Atlantic campaign. Initially the group was composed of four boats : , , and . T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Line (shipping Company)
The Silver Line was a shipping company formed in 1908, part of the British Merchant Navy. By the 1930s they were offering round the world passenger/cargo services, with the passenger fare on a freighter £100. Entirely on foreign service, the ships did not include UK ports of call. Managing owners were the S & J Thompson family. Most of their merchant ships bore the name Silver followed by the name of a tree. The Second World War claimed 11 of their ships. One of them, the ''Silverfir'', was sunk by the German battleship on a voyage from Manchester to New York in 1941. Silver Line switched to tramping around the world in the 1950s, then went through several ownership changes, and by 1985, with the sale of their last ship, was no more. The ''Silverplane'', a sleek twin funnel vessel of 7,226 gross tons built in 1948, was sold to the Cunard Line in 1951 and renamed ''Alsatia II'', and so was her sister ship ''Silverbriar'', to become ''Andria I''. Their forward funnels were fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ASDIC
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extrem ...

Nicolai Clausen
The Knight's Cross of the Iron Cross (german: Ritterkreuz des Eisernen Kreuzes) and its variants were the highest awards in the military and paramilitary forces of Nazi Germany during World War II. The Knight's Cross of the Iron Cross was awarded for a wide range of reasons and across all ranks, from a senior commander for skilled leadership of his troops in battle to a low-ranking soldier for a single act of extreme gallantry. A total of 7,321 awards were made between its first presentation on 30 September 1939 and its last bestowal on 17 June 1945. This number is based on the acceptance by the Association of Knight's Cross Recipients (AKCR). Presentations were made to members of the three military branches of the Wehrmacht—the Heer (Army), Kriegsmarine (Navy) and Luftwaffe (Air Force)—as well as the Waffen-SS, the Reich Labour Service, and the Volkssturm (German national militia). There were also 43 foreign recipients of the award. These recipients are listed in the 1986 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
