Blockship
A blockship is a ship deliberately sunk to prevent a river, channel, or canal from being used. It may either be sunk by a navy defending the waterway to prevent the ingress of attacking enemy forces, as in the case of at Portland Harbour in 1914; or it may be brought by enemy raiders and used to prevent the waterway from being used by the defending forces, as in the case of the three old cruisers , and scuttled during the Zeebrugge raid in 1918 to prevent the port from being used by the German navy. An early use was in 1667, during the Dutch Raid on the Medway and their attempts to do likewise in the Thames during the Second Anglo-Dutch War, when a number of warships and merchant ships commandeered by the Royal Navy were sunk in those rivers to attempt to stop the attacking forces. An even earlier use are the six 11th century Skuldelev ships in Roskilde Fjord, sunk to protect Roskilde from northern Vikings. They are now on display in the Viking Ship Museum.

Zeebrugge Raid
The Zeebrugge Raid ( nl, Aanval op de haven van Zeebrugge; ) on 23 April 1918, was an attempt by the Royal Navy to block the Belgian port of Bruges-Zeebrugge. The British intended to sink obsolete ships in the canal entrance, to prevent German vessels from leaving port. The port was used by the Imperial German Navy as a base for U-boats and light shipping, which were a threat to Allied control of the English Channel and southern North Sea. Several attempts to close the Flanders ports by bombardment failed and Operation Hush, a 1917 plan to advance up the coast, proved abortive. As ship losses to U-boats increased, finding a way to close the ports became urgent and the Admiralty became more willing to consider a raid. An attempt to raid Zeebrugge was made on 2 April 1918 but was cancelled at the last moment, after the wind direction changed and made it impossible to lay a smokescreen to cover the ships. Another attempt was made on 23 April, with a concurrent attack on Ostend. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raid On The Medway
The Raid on the Medway, during the Second Anglo-Dutch War in June 1667, was a successful attack conducted by the Dutch navy on English warships laid up in the fleet anchorages off Chatham Dockyard and Gillingham in the county of Kent. At the time, the fortress of Upnor Castle and a barrier chain called the "Gillingham Line" were supposed to protect the English ships. The Dutch, under nominal command of Willem Joseph van Ghent and Lieutenant-Admiral Michiel de Ruyter, over several days bombarded and captured the town of Sheerness, sailed up the Thames estuary to Gravesend, then sailed into the River Medway to Chatham and Gillingham, where they engaged fortifications with cannon fire, burned or captured three capital ships and ten more ships of the line, and captured and towed away the flagship of the English fleet, . Politically, the raid was disastrous for King Charles' war plans and led to a quick end to the war and a favourable peace for the Dutch. It was one of the worst ...

Ship Of The Line
A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which depended on the two columns of opposing warships maneuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons firingand therefore more firepowertypically had an advantage. Since these engagements were almost invariably won by the heaviest ships carrying more of the most powerful guns, the natural progression was to build sailing vessels that were the largest and most powerful of their time. From the end of the 1840s, the introduction of steam power brought less dependence on the wind in battle and led to the construction of screw-driven wooden-hulled ships of the line; a number of purely sail-powered ships were converted to this propulsion mech ...

Stone Fleet
The Stone Fleet consisted of a fleet of aging ships (mostly whaleships) purchased in New Bedford and other New England ports, loaded with stone, and sailed south during the American Civil War by the Union Navy for use as blockships. They were to be deliberately sunk at the entrance of Charleston Harbor, South Carolina in the hope of obstructing blockade runners, then supplying Confederate interests. Although some sank along the way and others were sunk near Tybee Island, Georgia, to serve as breakwaters, wharves for the landing of Union troops, the majority were divided into two lesser fleets. One fleet was sunk to block the south channel off Morris Island, and the other to block the north channel near Rattlesnake Shoals off the present day Isle of Palms in what proved to be failed efforts to block access the main shipping channels into Charleston Harbor.Spence 1995, pp. 142–152, 159–164 History Various old ships, specifically purchased by the Navy for this purpose, were loa ...

Hulk (ship Type)
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to an old ship that has had its rigging or internal equipment removed, retaining only its buoyant qualities. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing. More recently, ships have been hulked when they become obsolete or when they become uneconomical to operate. Sheer hulk A sheer hulk (or shear hulk) w ...

Southern Naval Base (Ukraine)
Southern Naval Base ( uk, Південна військово-морська база, Russian: Южная военно-морская база) was a naval base of the Armed Forces of Ukraine located in the town of Novoozerne (part of Yevpatoria city municipality) at the Donuzlav Bay in the western part of Crimea. The base was reorganized in place of the Crimea Naval Base of the Soviet Union which completely occupyied the southern shores of Donuzlav Bay and included hovercraft berths, Donuzlav Air Station, and a submarine base. Most of the former base is disassembled, while the former Donuzlav Air Station is non-operational. Donuzlav Bay is separated from the Black Sea by two sandspits which serve as a small freight port of the Yevpatoriya Commercial Trade Port located in the city. History The naval base was established by Ukraine in 1996, having previously been a Soviet naval base from 1976 to 1991, and then a Russian base. It celebrated its 15th anniversary in 2011.

Skuldelev Ships
The Skuldelev ships are five original Viking ships recovered from the waterway of Peberrenden at Skuldelev, north of Roskilde in Denmark. In 1962, the remains of the submerged ships were excavated in the course of four months. The recovered pieces constitute five types of Viking ships and have all been dated to the 11th century. They are thought to have been sunk to prevent attacks from the sea. When the remains were unearthed, they were thought to comprise six ships, but "Skuldelev 2" and "Skuldelev 4" were later discovered to be parts of one ship. Together, the five Skuldelev ships provide a good source of information about the shipbuilding traditions of the late Viking Age and are now exhibited at the Viking Ship Museum in Roskilde. The museum has built accurate reconstructions of all five of the original Skuldelev ships; some of them have also been reconstructed by other groups across the world. Skuldelev 1 Skuldelev 1 was a sturdy seagoing cargo-vessel, possibly of the kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roskilde Fjord
Roskilde Fjord is the fjord north of Roskilde, Denmark. It is a long branch of the Isefjord. Cities The cities Frederiksværk, Frederikssund, Jægerspris, Jyllinge and Roskilde (including Himmelev), (home to the famous Roskilde Festival), all have coastline at Roskilde Fjord. The image on this page shows the view of the fjord, as seen from Roskilde. Viking Time During the Viking time around 1000 AD the people of Roskilde decided to sink a number of their ships in the fjord at Skuldelev in order to prevent the Vikings from coming in and raiding. Originally five were discovered; but while extending the museum that houses these finds another nine were uncovered.

Baltic Campaign Of 1854
The Crimean War, , was fought from October 1853 to February 1856 between Russia and an ultimately victorious alliance of the Ottoman Empire, France, the United Kingdom and Piedmont-Sardinia. Geopolitical causes of the war included the decline of the Ottoman Empire, the expansion of the Russian Empire in the preceding Russo-Turkish Wars, and the British and French preference to preserve the Ottoman Empire to maintain the balance of power in the Concert of Europe. The flashpoint was a disagreement over the rights of Christian minorities in Palestine, then part of the Ottoman Empire, with the French promoting the rights of Roman Catholics, and Russia promoting those of the Eastern Orthodox Church. The churches worked out their differences with the Ottomans and came to an agreement, but both the French Emperor Napoleon III and the Russian Tsar Nicholas I refused to back down. Nicholas issued an ultimatum that demanded the Orthodox subjects of the Ottoman Empire be place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viking Ship Museum (Roskilde)
The Viking Ship Museum ( da, Vikingeskibsmuseet) in Roskilde is Denmark's national ship museum for ships of the Prehistory, prehistoric and Middle Ages, medieval period. The main focus of the museum is a permanent exhibition of the Skuldelev ships, five original Viking ships excavated nearby in 1962. The Viking Ship Museum also conducts research and educates researchers in the fields of maritime history, Maritime archaeology, marine archaeology and experimental archaeology. Various academic conferences are held here and there is a research library in association with the museum. Original Viking ships Around the year 1070, five Viking ships were blockship, deliberately sunk at Skuldelev in Roskilde Fjord in order to block the most important fairway and to protect Roskilde from an enemy attack from the sea. These ships, later known as the Skuldelev ships, were excavated in 1962. They turned out to be five different types of ships ranging from cargo ships to ships of war. The Vi ...
