Coaling (ships)
The era of the steam warship powered exclusively by coal was relatively brief, lasting from 1871 until 1914. Although the French ironclad ''Gloire'' and the iron hulled in 1860 both had coal-fired boilers and funnels, their purpose was to provide additional speed in battle. Sails provided their main propulsion most of the time so, unlike , the first ship built without sails, these were not true steamships. Although much faster than sail, the lengthy refueling or coaling required by steam ships brought considerable additional risk to the ship and hardship to the crew. These drawbacks led to the replacement of coal by oil. Coal itself also required maintenance. Coal cannot be pumped and, once loaded, it had to be continuously moved to ensure bunkers nearest the boilers were always full should full power be suddenly needed. These problems were sufficiently serious for the Royal Navy to build as an oil-fired ship despite an abundance of coal and a shortage of oil in the United Kingd ...

Pearl Harbor Coaling Station In 1919
A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, ''pearl'' has become a metaphor for something rare, fine, admirable and valuable. The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as ''natural'' pearls. ''Cultured'' or ''farmed'' pearls from pearl oysters and freshwater mussels make up the majority of those currently sold. Imitation pearls are also widely s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Admiral Von Spee
Maximilian Johannes Maria Hubert Reichsgraf von Spee (22 June 1861 – 8 December 1914) was a naval officer of the German ''Kaiserliche Marine'' (Imperial Navy), who commanded the East Asia Squadron during World War I. Spee entered the navy in 1878 and served in a variety of roles and locations, including on a colonial gunboat in German West Africa in the 1880s, the East Africa Squadron in the late 1890s, and as commander of several warships in the main German fleet in the early 1900s. During his time in Germany in the late 1880s and early 1890s, he married his wife, Margareta, and had three children, his sons Heinrich and Otto and his daughter Huberta. By 1912, he had returned to the East Asia Squadron as its commander, and was promoted to the rank of ''Vizeadmiral'' (Vice Admiral) the following year. After the outbreak of World War I in July 1914, Spee led his squadron across the Pacific to the coast of South America. Here on 1 November, he defeated the British 4th Cruiser Sq ...

Steam Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as stratum, rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Wales Coalfield
The South Wales Coalfield ( cy, Maes glo De Cymru) extends across Pembrokeshire, Carmarthenshire, Swansea, Neath Port Talbot, Bridgend, Rhondda Cynon Taf, Merthyr Tydfil, Caerphilly, Blaenau Gwent and Torfaen. It is rich in coal deposits, especially in the South Wales Valleys. Description It comprises a fully exposed synclinorium with a varying thickness of coal measures (Upper Carboniferous/Pennsylvanian) with thick, workable seams in the lower parts and generally thinner and sparser seams in the upper parts, together with a development of sandstones (Pennant Sandstone). These sandstones have been much used in building construction (including the characteristic terraces of former miners' houses) and give rise to bleak uplands rising 300–600 metres above sea level between the steep-sided valleys in which most deep mines were developed. The coal generally increases in grade or "rank" from east to west, with bituminous coals in the east, and anthracite in the west, mostly to ...

Severn Tunnel
The Severn Tunnel ( cy, Twnnel Hafren) is a railway tunnel in the United Kingdom, linking South Gloucestershire in the west of England to Monmouthshire in south Wales under the estuary of the River Severn. It was constructed by the Great Western Railway (GWR) between 1873 and 1886 for the purpose of dramatically shortening the journey times of their trains, passenger and freight alike, between South Wales and Western England. It has often been regarded as the crowning achievement of GWR's chief engineer Sir John Hawkshaw. Prior to the tunnel's construction, lengthy detours were necessary for all traffic between South Wales and Western England, which either used ship or a lengthy diversion upriver via . Recognising the value of such a tunnel, the GWR sought its development, tasking Hawkshaw with its design and later contracting the civil engineer Thomas A. Walker to undertake its construction, which commenced in March 1873. Work proceeded smoothly until October 1879, at which poi ...

Christopher Cradock
Rear Admiral Sir Christopher "Kit" George Francis Maurice Cradock (2 July 1862 – 1 November 1914) was an English senior officer of the Royal Navy. He earned a reputation for great gallantry. Appointed to the royal yacht, he was close to the British royal family. Prior to the First World War, his combat service during the Mahdist War and the Boxer Rebellion was all ashore. Appointed Commander-in-Chief of the North America and West Indies Station before the war, his mission was to protect Allied merchant shipping by hunting down German commerce raiders. Late in 1914 he was tasked to search for and destroy the East Asia Squadron of the Imperial German Navy as it headed home around the tip of South America. Believing that he had no choice but to engage the squadron in accordance with his orders, despite his numerical and tactical inferiority, he was killed during the Battle of Coronel off the coast of Chile in November when the German ships sank his flagship.

French Ironclad Gloire
The French ironclad ''Gloire'' (, "Glory") was the first ocean-going ironclad, launched in 1859. It was developed after the Crimean War,The Battle of Sinop at the start of the war convinced the world's naval powers that wooden warships could not withstand the new weapons. in response to new developments of naval gun technology, especially the Paixhans guns and rifled guns, which used explosive shells with increased destructive power against wooden ships, and after the development of the ironclad floating batteries built by the British and French for the bombardment of Russian forts during the Crimean War. Design and description ''Gloire'' was designed by the French naval architect Henri Dupuy de Lôme as a 5,630-ton broadside ironclad with a wooden hull. Its 12 cm-thick (4.7 in) armour plates, backed with 43 cm (17 in) of timber, resisted hits by the experimental shooting of the strongest guns of the time (the French 50-pounder and the British 68-pounder) ...

Borodino-class Battleship
The ''Borodino''-class battleships were a group of five pre-dreadnought battleships built for the Imperial Russian Navy around the end of the 19th century. Their design was based on that of the French-built modified to use Russian equipment. The first four ships were finished after the start of the Russo-Japanese War of 1904–1905 and were among the ships ordered to sail from the Baltic Sea to the Far East to relieve the Pacific Squadron besieged by the Japanese in Port Arthur. Three of these ships were sunk and one was captured by the Imperial Japanese Navy at the Battle of Tsushima in 1905. The fifth and final ship, , was not completed in time to participate in the war and served with the Baltic Fleet through World War I. Design and description Tsar Nicholas II had desired a warm-water port on the Pacific since his accession to the throne in 1894. He achieved this ambition in March 1898 when Russia signed a 25-year lease for Port Arthur and the Liaotung Peninsula with C ...

Battle Of Tsushima
The Battle of Tsushima (Japanese:対馬沖海戦, Tsushimaoki''-Kaisen'', russian: Цусимское сражение, ''Tsusimskoye srazheniye''), also known as the Battle of Tsushima Strait and the Naval Battle of Sea of Japan (Japanese: 日本海海戦, Nihonkai''-Kaisen'') in Japan, was a List of battles of the Russo-Japanese War, major naval battle fought between Russia and Japan during the Russo-Japanese War. It was naval history's first, and so far the last, decisive sea battle fought by modern steel battleship fleets and the first naval battle in which wireless telegraphy (radio) played a critically important role. It has been characterized as the "dying echo of the old era – for the last time in the history of naval warfare, Ship of the line, ships of the line of a beaten fleet surrendered on the high seas". It was fought on 27–28 May 1905 (14–15 May in the Julian calendar then in use in Russia) in the Tsushima Strait located between Korea and southern Japan ...
