Fort Jay
Fort Jay is a coastal bastion fort and the name of a former United States Army post on Governors Island in New York Harbor, within New York City. Fort Jay is the oldest existing defensive structure on the island, and was named for John Jay, a member of the Federalist Party, New York governor, Chief Justice of the United States, Secretary of State, and one of the founding fathers of the United States. It was built in 1794 to defend Upper New York Bay, but has served other purposes. From 1806 to 1904 it was named Fort Columbus, presumably for explorer Christopher Columbus. Today, the National Park Service administers Fort Jay and Castle Williams as the Governors Island National Monument. American Revolution Fort Jay is situated on Governors Island (which was known as Nutten Island from 1664 to 1784, based on Dutch ''Noten Eylandt'' for "Nut Island").

Governors Island
Governors Island is a island in New York Harbor, within the New York City borough of Manhattan. It is located approximately south of Manhattan Island, and is separated from Brooklyn to the east by the Buttermilk Channel.

About of the land area is fill, added in the early 1900s to the south of the original island. The native Lenape originally referred to Governors Island as Paggank ("nut island") because of the area's rich collection of chestnut, hickory, and oak trees; it is believed that this space was originally used for seasonal foraging and hunting.

Governors Island National Monument
Governors Island National Monument, a unit of the United States national park system, is located in New York City on of Governors Island, a island located off the southern tip of Manhattan Island at the confluence of the Hudson and East Rivers in New York Harbor. Conversion to public use In October 1995 the United States Coast Guard announced it would close its largest base, at Governors Island, as a cost savings measure. The Coast Guard had established the base on the island in 1966 after the U.S. Army closed Fort Jay, an Army post since 1794. In 1996, the Coast Guard closed the base and conveyed it as surplus property to the federal government's General Services Administration for disposal through transfer or sale. The closure was at the initiative of the Coast Guard, then a bureau of the U.S. Department of Transportation, which was seeking to close a $400 million budget gap. The closure of the base represented an estimated 30 million dollar savings. Since the closure was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jay Treaty
The Treaty of Amity, Commerce, and Navigation, Between His Britannic Majesty and the United States of America, commonly known as the Jay Treaty, and also as Jay's Treaty, was a 1794 treaty between the United States and Great Britain that averted war, resolved issues remaining since the Treaty of Paris of 1783 (which ended the American Revolutionary War), and facilitated ten years of peaceful trade between the United States and Britain in the midst of the French Revolutionary Wars, which began in 1792. The Treaty was designed by Alexander Hamilton and supported by President George Washington. It angered France and bitterly divided Americans. It inflamed the new growth of two opposing parties in every state, the pro-Treaty Federalists and the anti-Treaty Jeffersonian Republicans. The Treaty was negotiated by John Jay and gained many of the primary American goals. This included the withdrawal of British Army units from forts in the Northwest Territory that it had refused to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacis
A glacis (; ) in military engineering is an artificial slope as part of a medieval castle or in early modern fortresses. They may be constructed of earth as a temporary structure or of stone in more permanent structure. More generally, a glacis is any slope, natural or artificial, which fulfils the above requirements. The etymology of this French word suggests a slope made dangerous with ice, hence the relationship with '' glacier''. A ''glacis plate'' is the sloped front-most section of the hull of a tank or other armoured fighting vehicle. Ancient fortifications A glacis could also appear in ancient fortresses, such as the one the ancient Egyptians built at Semna in Nubia. Here it was used by them to prevent enemy siege engines from weakening defensive walls. Hillforts in Britain started to incorporate glacis around 350 BC. Those at Maiden Castle, Dorset were high. Medieval fortifications Glacis, also called talus, were incorporated into medieval fortification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ravelin
A ravelin is a triangular fortification or detached outwork, located in front of the innerworks of a fortress (the curtain walls and bastions). Originally called a ''demi-lune'', after the ''lunette'', the ravelin is placed outside a castle and opposite a fortification curtain wall. The ravelin is the oldest and at the same time the most important outer work of the bastion fortification system. It originated from small forts that were supposed to cover the bridge that led across the moat to the city or fortress gate from a direct attack. From this original function, to protect the gate bridge, also comes its original Italian name "''rivellino''" (which means small bank work or with the German expression common for it: ''Brückenkopf'' – "bridge head"). Therefore, the ravelin was at first only a small work, which should only make the access to the bridge in front of the fortress gates more difficult. When it was realized in the 16th century that this would generally provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seacoast Defense In The United States
Seacoast defense was a major concern for the United States from its independence until World War II. Before airplanes, many of America's enemies could only reach it from the sea, making coastal forts an economical alternative to standing armies or a large navy. After the 1940s, it was recognized that fixed fortifications were obsolete and ineffective against aircraft and missiles. However, in prior eras foreign fleets were a realistic threat, and substantial fortifications were built at key locations, especially protecting major harbors. The defenses heavily depended on fortifications but also included submarine minefields, nets and booms, ships, and airplanes. Therefore, all of the armed forces participated in seacoast defense, but the U.S. Army Corps of Engineers played the central role in constructing fixed defenses. Designs evolved and became obsolete with changes in the technology available to both the attacking forces and the defenders. The evolution of the U.S. seacoas ...

Evacuation Day (New York)
Evacuation Day on November 25 marks the day in 1783 when the British Army departed from New York City on Manhattan Island, after the end of the American Revolutionary War. In their wake, General George Washington triumphantly led the Continental Army from his headquarters north of the city across the Harlem River, and south through Manhattan to the Battery at its southern tip. History Background Following the significant losses at the Battle of Long Island on August 27, 1776, General George Washington and the Continental Army retreated across the East River by benefit of both a retreat and holding action by well-trained Maryland Line troops at Gowanus Creek and Canal and a night fog which obscured the barges and boats evacuating troops to Manhattan Island. On September 15, 1776, the British flag replaced the American atop Fort George, where it was to remain until Evacuation Day.

After defeating the British in the siege of Boston on March 17, commander-in-chief George Washington relocated the Continental Army to defend the port city of New York, located at the southern end of Manhattan Island. Washington understood that the city's harbor would provide an excellent base for the Royal Navy, so he established defenses there and waited for the British to attack. In July, the British, under the com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
