HMS Decoy (1871)
HMS ''Decoy'' was an composite gunboat of the Royal Navy, built at Pembroke Dockyard and launched on 12 October 1871. She served in both the Third Anglo-Ashanti War in 1873 and the Bombardment of Alexandria in 1882. She rapidly became obsolete and was sold in 1885. Design and construction Designed by Sir Edward Reed, Chief Constructor of the Royal Navy, the ''Ariel''-class gunboats were the first gunboats of composite construction. She was armed with two 64-pounder (56 cwt) muzzle-loading rifles and two 20-pounder Armstrong breech loaders. All four guns were mounted on traversing carriages. All the ships of the class carried a three-masted barquentine rig. Operational service ''Decoy'' was deployed off the coast of West Africa to support the operations on the Gold Coast. She deployed with and . She also took part in the bombardment of Bootry. In 1882 she formed part of the Naval and Military forces at the Bombardment of Alexandria The Bombardment of Alexandria in Egy ...

Pembroke Dockyard
Pembroke Dockyard, originally called Pater Yard, is a former Royal Navy Dockyard in Pembroke Dock, Pembrokeshire, Wales. History It was founded in 1814, although not formally authorized until the Prince Regent signed the necessary Order in Council on 31 October 1815, and was known as ''Pater Yard'' until 1817. The Mayor of Pembroke had requested the change "in deference to the town of Pembroke some distant". The site selected for the dockyard was greenfield land and the closest accommodations were in Pembroke. Office space was provided by the old frigate after she was beached. The Royal Marine garrison was housed in the hulked 74-gun ship, , after she was run aground in 1832. Many of the workmen commuted by boat from nearby communities until Pembroke Dock town was built up. In 1860 the dockyard's policing was transferred to the new No. 4 Division of the Metropolitan Police, which remained in that role until the 1920s. After the end of the First World War, the dockyard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Builder's Old Measurement
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam (nautical), beam. It is expressed in "tons burden" ( en-em , burthen , enm , byrthen ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in foot (length), feet, from the stem (ship), stem to the sternpost; * ''Beam (nautical), Beam'' is the maximum beam, in feet. The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom. The Moorsom system calculates the cargo-carrying capaci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Barquentine
A barquentine or schooner barque (alternatively "barkentine" or "schooner bark") is a sailing vessel with three or more masts; with a square rigged foremast and fore-and-aft rigged main, mizzen and any other masts. Modern barquentine sailing rig While a full-rigged ship is square-rigged on all three masts, and the barque is square-rigged except for the mizzen-mast, the barquentine extends the principle by making only the foremast square-rigged. The advantages of a smaller crew, good performance before the wind and the ability to sail relatively close to the wind while carrying plenty of cargo made it a popular rig at the end of the nineteenth century. Today, barquentines are popular with modern tall ship and sail training operators as their suite of mainly fore-and-aft sails improve non-downwind performance, while their foremast of square sails offers long distance downwind speed and dramatic appearance in port. Etymology The term "barquentine" is seventeenth century in ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RBL 20 Pounder Armstrong Gun
The Armstrong Breech Loading 20-pounder gun, later known as RBL 20-pounder, was an early modern 3.75-inch rifled breech-loading light gun of 1859. History The gun was effectively a larger version of the successful RBL 12 pounder 8 cwt Armstrong gun. There were different versions for land and sea service. Sea service The RBL 20 pounder of 13 cwt and 15 cwt for sea service was introduced in 1859. It is 2½ feet shorter than the land version giving it a bore of only 54 inches (14.43 calibres), and hence a short stubby appearance. Its short barrel only allowed it to attain a muzzle velocity of 1,000 ft/second. The 15 cwt gun, identifiable by the raised coil in front of the vent slot, was intended for broadside use in sloops. The more lightly constructed 13 cwt gun was known as a pinnace gun and was intended for boat use. Land service The RBL 20 pounder of 16 cwt for land service was introduced in 1860. It has a bore of 84 inches (22.36 calibres) and hence has the ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglo-Ashanti Wars
The Anglo-Ashanti wars were a series of five conflicts that took place between 1824 and 1900 between the Ashanti Empire—in the Akan interior of the Gold Coast—and the British Empire and its African allies. Though the Ashanti emerged victorious in some of these conflicts, the British ultimately prevailed in the fourth and fifth conflicts, resulting in the complete annexation of the Ashanti Empire by 1900. The wars were mainly due to Ashanti attempts to establish a stronghold over the coastal areas of present-day Ghana. Coastal peoples such as the Fante and the Ga came to rely on British protection against Ashanti incursions. Earlier wars The British fought three earlier wars in the Gold Coast: In the Ashanti-Fante War of 1806–07, the British refused to hand over two rebels pursued by the Ashanti, but eventually handed one over (the other escaped). In the Ga-Fante War of 1811, the Ashanti sought to aid their Ga allies in a war against the Fante and their British allie ...

Bombardment Of Alexandria
The Bombardment of Alexandria in Egypt by the British Mediterranean Fleet took place on 11–13 July 1882. Admiral Beauchamp Seymour was in command of a fleet of fifteen Royal Navy ironclad ships which had previously sailed to the harbor of Alexandria to support the khedive Tewfik Pasha amid Ahmed 'Urabi's nationalist uprising against his administration and its close ties to British and French financiers. He was joined in the show of force by a French flotilla as well. The move provided some security to the khedive, who withdrew his court to the now-protected port, but strengthened 'Urabi's nationalists within the army and throughout the remainder of Egypt. On 11 June, anti-European riots began in Alexandria. The city's European residents fled and the Egyptian 'Urabist army began fortifying and arming the harbor. An ultimatum to cease this build-up being refused, the British fleet began a 10½-hour bombardment of the city without French assistance. Historians argue about ...

Elmina Bombardment 1873
Elmina, also known as Edina by the local Fante, is a town and the capital of the Komenda/Edina/Eguafo/Abirem District on the south coast of Ghana in the Central Region, situated on a bay on the Atlantic Ocean, west of Cape Coast. Elmina was the first European settlement in West Africa and it has a population of 33,576 people. History Prior to the arrival of the Portuguese, the town was called Anomansah ("perpetual" or "inexhaustible drink") from its position on the peninsula between the Benya lagoon and the sea. In 1478 (during the War of the Castilian Succession), a Castilian armada of 35 caravels and a Portuguese fleet fought a large naval battle near Elmina for the control of the Guinea trade (gold, slaves, ivory and melegueta pepper), the Battle of Guinea. The war ended with a Portuguese naval victory, followed by the official recognition by the Catholic Monarchs of Portuguese sovereignty over most of the West African territories in dispute embodied in the Treaty of ...
