Fort Drum (Philippines)
Fort Drum, also known as El Fraile Island ( tl, Pulo ng El Fraile), is a heavily fortified island situated at the mouth of Manila Bay in the Philippines, due south of Corregidor Island. Nicknamed a "concrete battleship", the reinforced concrete sea fort, shaped like a battleship, was built by the United States in 1909 as one of the harbor defenses at the wider South Channel entrance to the Bay during the American colonial period. It was unique among forts built by the United States between the American Civil War and early World War II, as it was a sea fort with turrets. It was captured and occupied by the Japanese during World War II, and was recaptured after U.S. forces ignited petroleum and gasoline in the fort, the conflagration killing 68 Japanese soldiers and leaving it permanently out of commission. Due to the high temperature caused by the conflagration it took five days before U.S. soldiers could enter the fortress. The now-abandoned fort was named after Brigadier G ...

Harbor Defenses Of Manila And Subic Bays
The Harbor Defenses of Manila and Subic Bays ("Coast Defenses of Manila and Subic Bays" until 1925) (a.k.a. CD/HD Manila Bay) were a United States Army Coast Artillery Corps harbor defense command, part of the Philippine Department of the United States Army from circa 1910 through early World War II. The command primarily consisted of four forts on islands at the entrance to Manila Bay and one fort on an island in Subic Bay.McGovern and Berhow 2003, pp. 7-12 Background and construction The United States acquired the Philippines as a territory as a result of the Spanish–American War in 1898. The Taft Board of 1905 recommended extensive, then-modern fortifications at the entrance to Manila Bay. The islands there had been declared military reservations on 11 April 1902. Accordingly, El Fraile, Carabao, Corregidor, Grande, and Caballo Islands in the Philippines were to be fortified and incorporated into the harbor defenses of Manila and Subic Bays, protecting the bases of the ...

Combustion
Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion does not always result in fire, because a flame is only visible when substances undergoing combustion vaporize, but when it does, a flame is a characteristic indicator of the reaction. While the activation energy must be overcome to initiate combustion (e.g., using a lit match to light a fire), the heat from a flame may provide enough energy to make the reaction self-sustaining. Combustion is often a complicated sequence of elementary radical reactions. Solid fuels, such as wood and coal, first undergo endothermic pyrolysis to produce gaseous fuels whose combustion then supplies the heat required to produce more of them. Combustion is often hot enough that incandescent light in the form of either glowing or a flame is prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Drum Before
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they a ...

Battle Of Manila Bay
The Battle of Manila Bay ( fil, Labanan sa Look ng Maynila; es, Batalla de Bahía de Manila), also known as the Battle of Cavite, took place on 1 May 1898, during the Spanish–American War. The American Asiatic Squadron under Commodore George Dewey engaged and destroyed the Spanish Pacific Squadron under ''Contraalmirante'' (Rear admiral) Patricio Montojo. The battle took place in Manila Bay in the Philippines, and was the first major engagement of the Spanish–American War. The battle was one of the most decisive naval battles in history and marked the end of the Spanish colonial period in Philippine history. Tensions between Spain and the United States worsened over the Spanish conduct during their efforts to quell the Cuban War of Independence, with many Americans being agitated by largely falsified reports of Spanish atrocities against the Cuban population. In January 1898, fearing the fate of American interests in Cuba due to the war, the cruiser USS ''Maine'' ... [...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 s ...

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 roles. 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—fulfilled by frigates or 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-dreadnought battleship. With the advent of the dreadnought battleship before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Navy
The Spanish Navy or officially, the Armada, is the maritime branch of the Spanish Armed Forces and one of the oldest active naval forces in the world. The Spanish Navy was responsible for a number of major historic achievements in navigation, the most famous being the discovery of America and the first global circumnavigation by Elcano. For several centuries, it played a crucial logistical role in the expansion and consolidation of the Spanish Empire, and defended a vast trade network across the Atlantic Ocean between the Americas and Europe, and the Manila Galleon across the Pacific Ocean between the Philippines and the Americas. The Spanish Navy was the most powerful maritime force in the world from the late 15th century to the early 18th century. In the early 19th century, with the loss of most of its empire, Spain transitioned to a smaller fleet but maintained a major shipbuilding industry which produced important technical innovations. The Spanish Navy built and operat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonzalez Hontoria De 12 Cm Mod 1883
The Gonzalez Hontoria de 12 cm mod 1883 was a Spanish naval gun developed in the late 1800s that armed a variety of warships of the Spanish Navy during the Spanish–American War. History The Hontoria guns were designed by José González Hontoria a Spanish inventor, field marshal of marine infantry and brigadier of the navy. During the 1800s Spain lagged behind other European powers in industrialization and Spain imported weapons from Krupp, Armstrong Whitworth and Schneider et Cie. During the 1860s and 1870s, Hontoria studied explosives, metallurgy, and industrial production with the aim of developing an indigenous arms industry. Construction In 1879 Hontoria designed a series of naval guns ranging from to which would lay the foundation for his later guns. The 1879 series like Ordóñez guns of the same period were breech loading, black powder, built up guns, with steel A tube and cast iron reinforcing hoops. The 1883 series was a step forward in that they were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Dewey
George Dewey (December 26, 1837January 16, 1917) was Admiral of the Navy, the only person in United States history to have attained that rank. He is best known for his victory at the Battle of Manila Bay during the Spanish–American War, with the loss of only a single crewman on the American side. Dewey was born in Montpelier, Vermont. At age 15, Dewey's father enrolled him at Norwich University in Northfield, Vermont. Two years later Norwich expelled him for drunkenness and herding sheep into the barracks. Summarily, he entered the United States Naval Academy in 1854. He graduated from the academy in 1858 and was assigned as the executive lieutenant of the at the beginning of the Civil War. He participated in the capture of New Orleans and the Siege of Port Hudson, helping the Union take control of the Mississippi River.

Mexican–American War
The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the (''United States intervention in Mexico''), was an armed conflict between the United States and Mexico from 1846 to 1848. It followed the 1845 American annexation of Texas, which Mexico still considered its territory. Mexico refused to recognize the Velasco treaty, because it was signed by President Antonio López de Santa Anna while he was captured by the Texan Army during the 1836 Texas Revolution. The Republic of Texas was '' de facto'' an independent country, but most of its Anglo-American citizens wanted to be annexed by the United States. Sectional politics over slavery in the United States were preventing annexation because Texas would have been admitted as a slave state, upsetting the balance of power between Northern free states and Southern slave states. In the 1844 United States presidential election, Democrat James K. Polk was elected on a platform of exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
