BL 6 Inch Mk VII Naval Gun
The BL 6-inch gun Mark VII (and the related Mk VIII) was a British naval gun dating from 1899, which was mounted on a heavy travelling carriage in 1915 for British Army service to become one of the main heavy field guns in the First World War, and also served as one of the main coast defence guns throughout the British Empire until the 1950s. Background The gun superseded the QF six-inch gun of the 1890s, a period during which the Royal Navy had evaluated QF technology (i.e. loading propellant charges in brass cartridge cases) for all classes of guns up to to increase rates of fire. BL Mk VII returned to loading charges in silk bags after it was determined that with new single-action breech mechanisms a six-inch BL gun could be loaded, a vent tube inserted and fired as quickly as a QF six-inch gun. Cordite charges in silk bags stored for a BL gun were also considered to represent a considerable saving in weight and magazine space compared to the bulky brass QF cartridge ...

HMCS Prince David (F89)
HMCS ''Prince David'' was one of three Canadian National Steamships passenger liners that were converted for the Royal Canadian Navy (RCN), first to armed merchant cruisers at the beginning of Second World War, then infantry landing ships (medium) or anti-aircraft escort. For three years, they were the largest ships in the RCN. The three 'Prince' ships were a unique part of Canada's war effort: taken out of mercantile service, converted to armed merchant cruisers, two of them (''Prince David'' and ) were reconfigured to infantry landing ships and one () to an anti-aircraft escort; all three ships were paid off at war's end and then returned to mercantile service. In the early part of the war, as armed merchant cruisers equipped with antique guns and very little armour, ''Prince David'' and her sisters were sent to hunt enemy submarines and surface ships, tasks better suited to warships. As the needs of the RCN changed, so were the 'Prince' ships able to adapt to new roles. Thei ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

BL 6-inch Gun Mk XIX
The British British ordnance terms#BL, BL 6-inch gun Mk XIXI.e. Mark 19 : Britain at the time designated Marks (models) of ordnance using Roman numerals. This was a field gun and field ordnance normally used a different Mark series to naval ordnance, but unusually the next available Mark number in the 6-inch naval gun series was used, rather than Mark I as the first 6-inch BL field gun. was introduced in 1916 as a lighter and longer-range field gun replacement for the obsolescent BL 6-inch Mk VII naval gun, BL 6-inch gun Mk VII. History, description The majority of military planners before the First World War were wedded to the concept of fighting an offensive war of rapid maneuver which in a time before mechanization meant a focus on cavalry and light horse artillery firing shrapnel shells. Although the majority of combatants had heavy field artillery prior to the outbreak of the First World War, none had adequate numbers of heavy guns in service, nor had they foreseen the gr ...

Battle Of The Somme
The Battle of the Somme (; ), also known as the Somme offensive, was a battle of the First World War fought by the armies of the British Empire and the French Third Republic against the German Empire. It took place between 1 July and 18 November 1916 on both sides of the upper reaches of the river Somme (river), Somme in France. The battle was intended to hasten a victory for the Allies of World War I, Allies. More than three million men fought in the battle, of whom more than one million were either wounded or killed, making it one of the List of battles by casualties, deadliest battles in human history. The French and British had planned an offensive on the Somme during the Chantilly Conferences, Chantilly Conference in December 1915. The Allies agreed upon a strategy of combined offensives against the Central Powers in 1916 by the French, Russian, British and Italian armies, with the Somme offensive as the Franco-British contribution. The French army was to undertake the m ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Royal Garrison Artillery
The Royal Garrison Artillery (RGA) was formed in 1899 as a distinct arm of the British Army's Royal Artillery, Royal Regiment of Artillery serving alongside the other two arms of the Regiment, the Royal Field Artillery (RFA) and the Royal Horse Artillery (RHA). The RGA were the 'technical' branch of the Royal Artillery who were responsible for much of the professionalisation of technical gunnery that was to occur during the First World War. It was originally established to man the guns of the British Empire's forts and fortresses, including coastal artillery batteries, the heavy gun batteries attached to each infantry division and the guns of the siege artillery. The RGA was amalgamated with the RFA in 1924, from which time the only two arms within the Royal Regiment of Artillery have been the Royal Artillery and the Royal Horse Artillery. Organisation The Royal Garrison Artillery came into existence as a separate entity when existing coastal defence, mountain, siege and heav ...

Second Boer War
The Second Boer War (, , 11 October 189931 May 1902), also known as the Boer War, Transvaal War, Anglo–Boer War, or South African War, was a conflict fought between the British Empire and the two Boer republics (the South African Republic and Orange Free State) over Britain's influence in Southern Africa. The Witwatersrand Gold Rush caused a large influx of "Uitlander, foreigners" (''Uitlanders'') to the South African Republic (SAR), mostly British from the Cape Colony. As they, for fear of a hostile takeover of the SAR, were permitted to vote only after 14 years of residence, they protested to the British authorities in the Cape. Negotiations failed at the botched Bloemfontein Conference in June 1899. The conflict broke out in October after the British government decided to send 10,000 troops to South Africa. With a delay, this provoked a Boer and British ultimatum, and subsequent Boer Irregular military, irregulars and militia attacks on British colonial settlements in Natal ...

Percy Scott
Admiral Sir Percy Moreton Scott, 1st Baronet, (10 July 1853 – 18 October 1924) was a British Royal Navy officer and a pioneer in modern naval gunnery. During his career he proved to be an engineer and problem solver of some considerable foresight, ingenuity and tenacity. He did not, however, endear himself to the Navy establishment for his regular outspoken criticism of the Navy's conservatism and resistance to change and this undoubtedly slowed the acceptance of his most important ideas, notably the introduction of directed firing. In spite of this, his vision proved correct most of the time and he rose to the rank of admiral and amongst other honours was made baronet, a hereditary title. Early years Scott was educated at Eastman's Royal Naval Academy, Southsea, and entered the navy as a cadet in 1866, at the age of thirteen, and in 1868 received a post on HMS ''Forte'', a 50-gun frigate. He served in the Third Anglo-Ashanti War and was based at Cape Coast Castle. He ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Armed Merchantmen
An armed merchantman is a merchant ship equipped with guns, usually for defensive purposes, either by design or after the fact. In the days of sail, piracy and privateers, many merchantmen would be routinely armed, especially those engaging in long distance and high value trade. In more modern times, auxiliary cruisers were used offensively as merchant raiders to disrupt trade chiefly during both World War I and World War II, particularly by Germany. While armed merchantmen are clearly inferior to purpose-built warships, sometimes they have scored successes in combat against them. Examples include East Indiamen mimicking ships of the line and chasing off regular French warships in the Battle of Pulo Aura in 1804, and the sinking the Australian light cruiser in their battle in 1941, although ''Kormoran'' was also destroyed and had to be scuttled. Pre-20th century East Indiamen of various European countries were heavily armed for their long journeys to the Far East. In partic ...

Monitor (warship)
A monitor is a relatively small warship that is neither fast nor strongly armored but carries disproportionately large guns. They were used by some navies from the 1860s, during the First World War and with limited use in the Second World War. The original monitor was designed in 1861 by John Ericsson, who named it . Subsequent vessels of this type were accordingly classed as "monitors". They were designed for shallow waters and served as coastal ships. The term also encompassed more flexible breastwork monitors, and was sometimes used as a generic term for any turreted ship. In the early 20th century, the term was revived for shallow-draught armoured shore bombardment vessels, particularly those of the Royal Navy: the s carried guns firing heavier shells than any other warship ever has, seeing action (albeit briefly) against German targets during World War I. The ''Lord Clive'' vessels were scrapped in the 1920s. The term "monitor" also encompasses the strongest of riverine ...

Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—usually fulfilled by frigates or sloop-of-war, sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre- ...
