HMS Derwent (1903)
HMS ''Derwent'' was a Hawthorn Leslie-type River-class destroyer ordered by the Royal Navy under the 1901 – 1902 Naval Estimates. Named after the River Derwent in central England, she was the second ship to carry this name. Construction She was laid down on 12 June 1902 at the Hawthorn Leslie shipyard at Hebburn-on-Tyne and launched on 14 February 1903. She was completed on 1 July 1904. Her original armament was to be the same as the turtleback torpedo boat destroyers that preceded her. In 1906 the Admiralty decided to upgrade the armament by landing the five 6-pounder naval guns and shipping three 12-pounder 8 hundredweight (cwt) guns. Two were mounted abeam at the foc'x'le break and the third gun was mounted on the quarterdeck. Pre-War After commissioning she was assigned to the East Coast Destroyer Flotilla of the 1st Fleet and based at Harwich. In April 1909 she was assigned to the 3rd Destroyer Flotilla on its formation at Harwich. She remained until displaced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Ensign Of The United Kingdom
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convoy System
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas. Naval convoys Age of Sail Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century. The use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval convoy tactics had been developed to ward off pirates and privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer could ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, 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, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

History Of The Great War
The ''History of the Great War Based on Official Documents by Direction of the Committee of Imperial Defence'' (abbreviated to ''History of the Great War'' or ''British Official History'') is a series of concerning the war effort of the British state during the First World War. It was produced by the Historical Section of the Committee of Imperial Defence from 1915 to 1949; after 1919 Brigadier-General Sir James Edmonds was Director.

Dover Barrage
Dover () is a town and major ferry port in Kent, South East England. It faces France across the Strait of Dover, the narrowest part of the English Channel at from Cap Gris Nez in France. It lies south-east of Canterbury and east of Maidstone. The town is the administrative centre of the Dover District and home of the Port of Dover. Archaeological finds have revealed that the area has always been a focus for peoples entering and leaving Britain. The name derives from the River Dour that flows through it. In recent times the town has undergone transformations with a high-speed rail link to London, new retail in town with St James' area opened in 2018, and a revamped promenade and beachfront. This followed in 2019, with a new 500m Pier to the west of the Harbour, and new Marina unveiled as part of a £330m investment in the area. It has also been a point of destination for many illegal migrant crossings during the English channel migrant crisis. The Port of Dover provides mu ...

Dover Patrol
The Dover Patrol and later known as the Dover Patrol Force was a Royal Navy command of the First World War, notable for its involvement in the Zeebrugge Raid on 22 April 1918. The Dover Patrol formed a discrete unit of the Royal Navy based at Dover and Dunkirk for the duration of the First World War. Its primary task was to prevent enemy German shipping—chiefly submarines—from entering the English Channel ''en route'' to the Atlantic Ocean, thereby obliging the Imperial German Navy to travel via the much longer route around Scotland which was itself covered by the Northern Patrol. History In late July 1914, with war looming, 12 Tribal-class destroyers arrived at Dover to join the near obsolete destroyers already at anchor in the harbour, most of them built in the late 19th century. These destroyers formed the nucleus of the fledgling Dover Patrol, which, from its early beginnings as a modest and poorly equipped command, became one of the most important Royal Navy commands of t ...

Firth Of Forth
The Firth of Forth () is the estuary, or firth, of several Scottish rivers including the River Forth. It meets the North Sea with Fife on the north coast and Lothian on the south. Name ''Firth'' is a cognate of ''fjord'', a Norse word meaning a narrow inlet. ''Forth'' stems from the name of the river; this is ''*Vo-rit-ia'' (slow running) in Proto-Celtic, yielding '' Foirthe'' in Old Gaelic and '' Gweryd'' in Welsh. It was known as ''Bodotria'' in Roman times. In the Norse sagas it was known as the ''Myrkvifiörd''. An early Welsh name is ''Merin Iodeo'', or the "Sea of Iudeu". Geography and economy Geologically, the Firth of Forth is a fjord, formed by the Forth Glacier in the last glacial period. The drainage basin for the Firth of Forth covers a wide geographic area including places as far from the shore as Ben Lomond, Cumbernauld, Harthill, Penicuik and the edges of Gleneagles Golf Course. Many towns line the shores, as well as the petrochemical complexes at Gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chatham Dockyard
Chatham Dockyard was a Royal Navy Dockyard located on the River Medway in Kent. Established in Chatham in the mid-16th century, the dockyard subsequently expanded into neighbouring Gillingham (at its most extensive, in the early 20th century, two-thirds of the dockyard lay in Gillingham, one-third in Chatham). It came into existence at the time when, following the Reformation, relations with the Catholic countries of Europe had worsened, leading to a requirement for additional defences. Over 414 years Chatham Royal Dockyard provided more than 500 ships for the Royal Navy, and was at the forefront of shipbuilding, industrial and architectural technology. At its height, it employed over 10,000 skilled artisans and covered . Chatham dockyard closed in 1984, and of the Georgian dockyard is now managed as the Chatham Historic Dockyard visitor attraction by the Chatham Historic Dockyard Trust.

Beagle-class Destroyer
The ''Beagle'' class (officially redesignated as the G class in 1913) was a class of sixteen destroyers of the Royal Navy, all ordered under the 1908-1909 programme and launched in 1909 and 1910. The ''Beagle''s served during World War I, particularly during the Dardanelles Campaign of 1915. Design For the 1908–1909 shipbuilding programme, the British Admiralty decided to revert to a smaller, more affordable destroyer to follow-on from the large and fast (required to reach ) and the experimental . The destroyers needed sufficient range to operate across the North Sea in the event of a confrontation with Germany, which rendered the coastal destroyers which had been built as a low-cost supplement to the expensive Tribals outdated, requiring larger numbers of a cheaper standard destroyer.Friedman 2009, pp. 108, 114.Gardiner and Gray 1985, p. 74. While the Tribals were oil fuelled, it was decided to return to the use of coal for the new destroyers, because of concerns over t ...
