Erhard Maertens
Erhard Maertens or Eberhard Maertens (26 February 1891 – 5 May 1945) was a German Vizeadmiral of the Kriegsmarine during World War II. From 16 June 1941 to 5 May 1943, he was Chief of Office of Naval Intelligence, Naval War Command (german: Marinekommandoamt) in the Oberkommando der Marine. Maertens was known for underestimating British intelligence, and specifically, overrating the security of the Naval Enigma cipher machine. In 1941, he held a naval enquiry into the strength of Naval Enigma security after the capture of U-boat U-570, and attributed all the suspicious losses in U-boats at the time to the British Huff-Duff. In the second enquiry, ordered by the Commander-in-Chief of the Navy (german: Oberbefehlshaber der Kriegsmarine) Karl Dönitz, in May 1943, he investigated a number of areas, which exculpated Enigma security in the end, for the second time, incorrectly blaming British 9.7 centimetre centimetric radar for the massive losses in U-boats by mid 1943.

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Goodwin Sands
Goodwin Sands is a sandbank at the southern end of the North Sea lying off the Deal coast in Kent, England. The area consists of a layer of approximately depth of fine sand resting on an Upper Chalk platform belonging to the same geological feature that incorporates the White Cliffs of Dover. The banks lie between above the low water mark to around below low water, except for one channel that drops to around below. Tides and currents are constantly shifting the shoals. More than 2,000 ships are believed to have been wrecked upon the Goodwin Sands because they lie close to the major shipping lanes through the Straits of Dover. The few miles between the sands and the coast is also a safe anchorage, known as The Downs, used as a refuge from foul weather. Due to the dangers, the area – which also includes Brake Bank – is marked by numerous lightvessels and buoys. Notable shipwrecks include in 1703, in 1740, the in 1914, and the South Goodwin Lightship, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
