Montagu Bastion
The Montagu Bastion is one of many bastions which were designed to protect Gibraltar. Montagu was joined to Orange Bastion by a curtain wall known as Montagu Curtain and this bastion was protected by the Montagu Counterguard. History Montagu Bastion was built on the remains of the Spanish ''Plataforma de San Andrés'' ('' es, St. Andrew's Platform''). A British bastion already existed on this site in the 1730s and was enlarged in 1773 giving it a pentagonal shape. In the 1790s, Sir William Green, oversaw improvements to Gibraltar's fortifications. As part of this he had the Montagu and the Orange Bastions extended and in addition he arranged for counterguards to be constructed in front of them in the Gibraltar Harbour. The counterguard, which mirrors the shape of its bastion, had been authorised by the Duke of Richmond in 1787. The theory behind constructing a counterguard, like the Montagu Counterguard in 1804, is that the enemy has to first capture the counterguard in orde ...

Fortifications Of Gibraltar
The Gibraltar peninsula, located at the far southern end of Iberia, has great strategic importance as a result of its position by the Strait of Gibraltar where the Mediterranean Sea meets the Atlantic Ocean. It has repeatedly been contested between European and North African powers and has endured fourteen sieges since it was first settled in the 11th century. The peninsula's occupants – Moors, Spanish, and British – have built successive layers of fortifications and defences including walls, bastions, casemates, gun batteries, magazines, tunnels and galleries. At their peak in 1865, the fortifications housed around 681 guns mounted in 110 batteries and positions, guarding all land and sea approaches to Gibraltar. Hughes & Migos, p. 91 The fortifications continued to be in military use until as late as the 1970s and by the time tunnelling ceased in the late 1960s, over of galleries had been dug in an area of only . Gibraltar's fortifications are clustered in three m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Green (general)
General Sir William Green, 1st Baronet, of Marass, Kent (4 April 1725 – 10 January 1811) was an officer in the British Army. After receiving a private education in Aberdeen, Scotland and a military education at the Royal Military Academy in Woolwich, England, he was appointed as a practitioner engineer in 1743. Green served on the European continent until 1752, after which he was in Canada. There, he continued to advance through both the ordinary military and engineering ranks. Following his return to England, Green was named senior engineer for Gibraltar about 1761, and the next year promoted to lieutenant colonel. He was promoted to chief engineer for Gibraltar in 1770, and designed and executed a number of military works on the Rock. In 1772, his idea of a regiment of military artificers, to replace the civilian mechanics who had formerly constructed military works, came to fruition in the form of the Soldier Artificer Company, the predecessor of the Corps of Royal Sappers ...

Military History Of Gibraltar During World War II
The military history of Gibraltar during World War II exemplifies Gibraltar's position as a British fortress since the early 18th century and as a vital factor in British military strategy, both as a foothold on the continent of Europe, and as a bastion of British sea power. During World War II, Gibraltar served a vital role in both the Atlantic Theatre and the Mediterranean Theatre, controlling virtually all naval traffic into and out of the Mediterranean Sea from the Atlantic Ocean. In addition to its commanding position, Gibraltar provided a strongly defended harbour from which ships could operate in both the Atlantic and the Mediterranean. Force H, under the command of Vice-Admiral James Somerville was based in Gibraltar and had the task of maintaining naval superiority and providing a strong escort for convoys to and from the besieged island of Malta. During the course of the war, Gibraltar came under aerial bombardment from Vichy French aircraft and from aircraft o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QF 3 Inch 20 Cwt
The QF 3 inch 20 cwt anti-aircraft gun became the standard anti-aircraft gun used in the home defence of the United Kingdom against German airships and bombers and on the Western Front in World War I. It was also common on British warships in World War I and submarines in World War II. 20 cwt referred to the weight of the barrel and breech, to differentiate it from other 3 inch guns (1cwt = 1 hundredweight = , hence the barrel and breech together weighed ). While other AA guns also had a bore of , the term ''3 inch'' was only ever used to identify this gun in the World War I era, and hence this is what writers are usually referring to by ''3 inch AA gun''. Design and development The gun was based on a prewar Vickers naval QF gun with modifications specified by the War Office in 1914. These (Mk I) included the introduction of a vertical sliding breech-block to allow semi-automatic operation. When the gun recoiled and ran forward after firing, the motion also opened the bree ...

RML 10 Inch 18 Ton Gun
The RML 10-inch guns Mk I – Mk II were large rifled muzzle-loading guns designed for British battleships and monitors in the 1860s to 1880s. They were also fitted to the and flat-iron gunboats. They were also used for fixed coastal defences around the United Kingdom and around the British Empire until the early years of the 20th century. Design The 10-inch gun was a standard " Woolwich" design (characterised by having a steel A tube with relatively few broad, rounded and shallow rifling grooves) developed in 1868, based on the successful Mk III 9-inch gun, itself based on the "Fraser" system. The Fraser system was an economy measure applied to the successful Armstrong design for heavy muzzle-loaders, which were expensive to produce. It retained the Armstrong steel barrel surrounded by wrought-iron coils under tension, but replaced the multiple thin wrought-iron coils shrunk around it by a single larger coil (10 inch Mark I) or 2 coils (Mark II); the trunnion ring w ...

City Gate
A city gate is a gate which is, or was, set within a city wall. It is a type of fortified gateway. Uses City gates were traditionally built to provide a point of controlled access to and departure from a walled city for people, vehicles, goods and animals. Depending on their historical context they filled functions relating to defense, security, health, trade, taxation, and representation, and were correspondingly staffed by military or municipal authorities. The city gate was also commonly used to display diverse kinds of public information such as announcements, tax and toll schedules, standards of local measures, and legal texts. It could be heavily fortified, ornamented with heraldic shields, sculpture or inscriptions, or used as a location for warning or intimidation, for example by displaying the heads of beheaded criminals or public enemies. Notably in Denmark, many market towns used to have at least one city gate mostly as part of the city's fortifications, but duri ...

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named '' Alligator'' and ''Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, scale and ...

Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small stru ...
