HMS Grinder (1855)
HMS ''Grinder'' was a wooden 3-gun , launched on 7 March 1855. Although she served for nine years, her most active period was in her first year when she served in the Crimean War. Black Sea and Sea of Azov During the summer of 1855, ''Grinder'' carried out raids on Russian food and ammunition stores to prevent supplies reaching the Russian troops in the Crimea. ''Grinder'' and nine other gunboats (''Beagle, Boxer, Cracker, Curlew, Fancy, Jasper, Vesuvius'', ''Swallow'' and ''Wrangler'' ) were employed destroying fisheries and corn stores, as well as ammunition stores, around the Sea of Azov. Their raids forced the Russian land forces to maintain a state of constant readiness lest there be a landing. The British naval squadron, including ''Grinder'', was active on 23 September 1855 at the entrance to the Sea of Azov in destroying communications between Temryuk and Taman, an area of shallow seas, swamps and bridges. For some of this summer period, ''Grinder'', under the com ... [...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] |
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 ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schooner Rig
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for priv ...

Howitzer
A howitzer () is a long- ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target. Etymology The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (mode ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crimean War
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 placed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Beagle (1854)
HMS ''Beagle'' was a wooden-hulled second-class screw gunvessel launched in 1854 and sold in 1863. She was the third vessel of the Royal Navy to use the name. Design The Crimean War sparked a sudden need for shallow-draught, manoeuvrable vessels for inshore work in the Baltic and the Black Sea. The ''Arrow'' class of six wooden-hulled screw steamers were built during 1854 to a design by the Surveyor's Department. Construction was undertaken at two commercial yards on the Thames, R & H Green and C J Mare & Company, both of Leamouth, London. Two further designs of Crimean War gunvessel were ordered during 1855, the and the . The class was built as despatch vessels, but in 1856 were re-designated as second-class gunvessels. Propulsion A two-cylinder horizontal single expansion steam engine supplied by Humphrys, Tennant and Dykes provided through a single screw. Sail plan All ''Arrow''-class gunvessels were barque-rigged. Armament The ''Arrow'' class were provided with tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Of Azov Naval Campaign (1855)
During the Crimean War (1853–1856), a naval campaign was fought in the Sea of Azov between the Royal Navy and the French Navy against the Russian Navy between 25 May–22 November 1855. British and French warships struck at every vestige of Russian power along the coast of the Sea of Azov. Except for Rostov-on-Don and Azov, no town, depot, building or fortification was immune from attack and Russian naval power ceased to exist almost overnight. Contrary to established images of the Russian War, here was a campaign which was well-planned, dynamically led and overwhelmingly successful. The British authorities, significantly, issued the bar "Azoff" to the British Crimean War Medal The Crimea Medal was a campaign medal approved on 15 December 1854, for issue to officers and men of British units (land and naval) which fought in the Crimean War of 1854–56 against Russia. The medal was awarded with the British version of th ..., thus acknowledging the services of those who wag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Rate
In the rating system of the British Royal Navy used to categorise sailing warships, a first rate was the designation for the largest ships of the line. Originating in the Jacobean era The Jacobean era was the period in English and Scottish history that coincides with the reign of James VI of Scotland who also inherited the crown of England in 1603 as James I. The Jacobean era succeeds the Elizabethan era and precedes the Ca ... with the designation of Ships Royal capable of carrying at least 400 men, the size and establishment of first-rates evolved over the following 250 years to eventually denote ships of the line carrying at least 80 guns across three gundecks. By the end of the eighteenth century, a first-rate carried no fewer than 100 guns and more than 850 crew, and had a measurement (Builder%27s_Old_Measurement, burthen) tonnage of some 2,000 tons. Origins The concept of a rating system for British naval vessels dates to the accession of James I of England, follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmund Lyons, 1st Baron Lyons
Admiral Edmund Lyons, 1st Baron Lyons, (21 November 179023 November 1858) was an eminent British Admiral of the Royal Navy, and diplomat, who ensured Britain's victory in the Crimean War, during which he was Commander-in-Chief of the Mediterranean Fleet, by his contribution at the Siege of Sevastopol (1854–1855) with both the Royal Navy and the British Army. As a consequence of his 'intelligence and great ability', 'quiet humour', 'frankness and urbanity', and 'vigilance and practical skill', Lyons was appointed to ambassadorial positions in Sweden, and in Switzerland, and to the court of King Otto of Greece. Lyons (whose brother Vice-Admiral John Lyons was on at the Battle of Trafalgar and served as British Ambassador to Egypt) was the father of the diplomat Richard Lyons, 1st Viscount Lyons (who was the British Ambassador to the USA who solved the Trent Affair, and who was later British Ambassador to France).

Hugh Talbot Burgoyne
Captain Hugh Talbot Burgoyne VC (17 July 1833 – 7 September 1870) was an Irish recipient of the Victoria Cross. Born in Dublin, he was the son of John Fox Burgoyne and the grandson of John Burgoyne. Burgoyne was a 21-year-old Royal Navy lieutenant, serving in the Crimean War when he performed the deed for which he was awarded the VC. Details On 29 May 1855, in the Sea of Azov, Crimea, Lieutenant Burgoyne of HMS ''Swallow'', with Lieutenant Cecil William Buckley from HMS ''Miranda'' and Gunner John Robarts from HMS ''Ardent'', volunteered to land at a beach where the Russian army were in strength. They were out of covering gunshot range of the ships offshore and met considerable enemy opposition, but managed to set fire to corn stores and ammunition dumps and destroy enemy equipment before embarking again. Burgoyne was Commander on HMS ''Ganges'' under Captain John Fulford during that vessel's service in the waters of the Colonies of Vancouver Island and British Col ...
