Type 1936 Destroyers
The Type 1936 destroyers, also known as the ''Z17'' class, were a group of six destroyers built for Nazi Germany's ''Kriegsmarine'' during the late 1930s, shortly before the beginning of World War II. All six sister ships were named after German sailors who had been killed in World War I.Koop & Schmolke, pp. 98–102 They were engaged in training for most of the period between their completion and the outbreak of war, although several did participate in the occupation of Memel in Lithuania, in early 1939. When the war began in September 1939, the sisters helped to lay minefields in the German Bight and then helped to lay multiple minefields off the British coast in late 1939 and early 1940. All but one participated in Operation Weserübung, the German invasion of Norway in April; they were all sunk or scuttled during the naval Battles of Narvik except which was refitting at the time. She was transferred to France in September where she engaged British ships several times. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Destroyer Z21 Wilhelm Heidkamp
Z21 ''Wilhelm Heidkamp'' was one of six Type 1936 destroyers built for the ''Kriegsmarine'' (German Navy) in the late 1930s. Completed a few months before the start of World War II in September 1939, the ship served as a flagship throughout her career. She briefly patrolled the Skagerrak where she inspected neutral shipping for contraband goods. ''Z21 Wilhelm Heidkamp'' later helped to lay four offensive minefields off the English coast that claimed two British destroyers, 2 fishing trawlers, and twenty-seven merchant ships. During the German invasion of Norway in April 1940, she sank a Norwegian coastal defense ship off Narvik and was crippled with the opening shots of the First Naval Battle of Narvik on 10 April, with the loss of 81 crewmen. The ship sank the following day. Design and description ''Z21 Wilhelm Heidkamp'' had an overall length of and was long at the waterline. The ship had a beam of , and a maximum draft of . She displaced at standard load and at dee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operation Zitronella
Operation Zitronella, also known as (Operation Sicily), was an eight-hour German raid on Spitzbergen, in the Svalbard Archipelago, on 8 September 1943. The battleships (in its only offensive action) and , plus nine destroyers, sailed to the archipelago, bombarded Allied-occupied settlements in Isfjorden and covered a landing party. Six Norwegians were killed and 31 were taken prisoner; sixteen Germans were wounded, one dying of his wounds. Background Svalbard The Svalbard Archipelago is in the Arctic Ocean, from the North Pole and a similar distance to Norway to the south. The islands are mountainous, with permanently snow-covered peaks, some glaciated; there are occasional river terraces at the bottom of steep valleys and some coastal plains. In winter, the islands are covered in snow and the bays ice over. To the west, Spitzbergen Island has several large fiords along its west coast; Isfjorden being up to wide. The Gulf Stream warms the waters and the sea is ice-free du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Grounding
Ship grounding or ship stranding is the impact of a ship on seabed or waterway side. It may be intentional, as in beaching (nautical), beaching to land crew or cargo, and careening, for maintenance or repair, or unintentional, as in a marine accident. In accidental cases, it is commonly referred to as "running aground". When unintentional, grounding may result simply in stranding, with or without damage to the submerged part of the ship's hull. Breach of the hull may lead to significant flooding, which in the absence of containment in watertight bulkheads may substantially compromise the ship's structural integrity, stability, and safety. As hazard Severe grounding applies extreme loads upon ship structures. In less severe accidents, it might result only in damage to the hull; however, in most serious accidents, it might lead to hull breaches, cargo spills, total loss of the vessel, and, in the worst cases, human casualties. Grounding accounts for about one-third of commercia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991.

Operation Barbarossa
Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and several of its European Axis allies starting on Sunday, 22 June 1941, during World War II. More than 3.8 million Axis troops invaded the western Soviet Union along a front, with the main goal of capturing territory up to a line between Arkhangelsk and Astrakhan, known as the A-A line. The attack became the largest and costliest military offensive in history, with around 10 million combatants taking part in the opening phase and over 8 million casualties by the end of the operation on 5 December 1941. It marked a major escalation of World War II, opened the Eastern Front—the largest and deadliest land war in history—and brought the Soviet Union into the Allied powers. The operation, code-named after the Holy Roman Emperor Frederick Barbarossa ("red beard"), put into action Nazi Germany's ideological goals of eradicating communism and conquering the western Soviet Union to repopulate it w ...

Battles Of Narvik
The Battles of Narvik were fought from 9 April to 8 June 1940, as a naval battle in Ofotfjord and as a land battle in the mountains surrounding the north Norwegian town of Narvik, as part of the Norwegian Campaign of the Second World War. The two naval battles in Ofotfjord on 10 April and 13 April were fought between the British Royal Navy and the German ''Kriegsmarine'', while the two-month land campaign was fought by Norwegian, French, British, and Polish troops against German mountain troops, shipwrecked ''Kriegsmarine'' sailors, and German paratroopers (''Fallschirmjäger'') from the 7th Air Division. Although defeated at sea off Narvik, losing control of the town of Narvik and being pushed back towards the Swedish border, the Germans eventually prevailed because of the Allied evacuation from Norway in June 1940 following the Battle of France. Narvik provided an ice-free harbour in the North Atlantic for iron ore transported by rail from Kiruna in Sweden. Both sides ...

Scuttled
Scuttling is the act of deliberately sinking a ship by allowing water to flow into the hull, typically by its crew opening holes in its hull. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force; as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in t ...

Operation Weserübung
Operation Weserübung ( , , 9 April – 10 June 1940) was the invasion of Denmark and Norway by Nazi Germany during World War II. It was the opening operation of the Norwegian Campaign. In the early morning of 9 April 1940 (, "Weser Day"), German forces occupied Denmark and invaded Norway, ostensibly as a preventive manoeuvre against a planned Anglo-French Military occupation, occupation of Norway known as Plan R 4, which developed as a response to a German invasion of Norwegian territory. After the rapid occupation of Denmark, in which the Danish military was ordered to stand down as Denmark's government did not declare war with Germany, German envoys informed the governments of Denmark and Norway that Germany's forces had come to protect both countries against Anglo-French attacks. Significant differences in geography, location and climate between the two nations made the actual military operations very dissimilar. The invasion fleet's nominal landing time, (Weser Time), wa ...

German Bight
The German Bight ( ; ; ); ; ; sometimes also the German Bay) is the southeastern bight of the North Sea bounded by the Netherlands and Germany to the south, and Denmark and Germany to the east (the Jutland peninsula). To the north and west it is limited by the Dogger Bank. The Bight contains the Frisian and Danish Islands. The Wadden Sea is approximately ten to twelve kilometres wide at the location of the German Bight. The Frisian islands and the nearby coastal areas are collectively known as Frisia. The southern portion of the bight is also known as the Heligoland Bight. Between 1949 and 1956 the BBC Sea Area Forecast (Shipping Forecast) used " Heligoland" as the designation for the area now referred to as German Bight. Use The German Bight contains some of Germany's largest national parks by area, the aim of which is to protect the Wadden Sea, a UNESCO World Heritage Site in the "nature" category. Due to being divided among three different states of Germany those pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minefield
A land mine, or landmine, is an explosive weapon often concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets as they pass over or near it. Land mines are divided into two types: anti-tank mines, which are designed to disable tanks or other vehicles; and anti-personnel mines, designed to injure or kill people. Land mines are typically pressure activated, exploding automatically when stepped on by a person or driven over by a vehicle, though alternative detonation mechanisms are sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Land mines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their indiscriminate nature and their potential to remain dangerous many years after a conflict has ended, harming civilians and the economy. With pressure from a number of campaign gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithuania
Lithuania, officially the Republic of Lithuania, is a country in the Baltic region of Europe. It is one of three Baltic states and lies on the eastern shore of the Baltic Sea, bordered by Latvia to the north, Belarus to the east and south, Poland to the south, and the Russian exclave, semi-exclave of Kaliningrad Oblast to the southwest, with a Maritime boundary, maritime border with Sweden to the west. Lithuania covers an area of , with a population of 2.89 million. Its capital and largest city is Vilnius; other major cities include Kaunas, Klaipėda, Šiauliai and Panevėžys. Lithuanians who are the titular nation and form the majority of the country's population, belong to the ethnolinguistic group of Balts and speak Lithuanian language, Lithuanian. For millennia, the southeastern shores of the Baltic Sea were inhabited by various Balts, Baltic tribes. In the 1230s, Lithuanian lands were united for the first time by Mindaugas, who formed the Kingdom of Lithuania on 6 July ...
