Why is the United States Military Academy called West Point?
The United States Military Academy is called West Point because it is on the western point of an S-turn on the Hudson River.  During the American Revolution, the Revolutionary Army stretched an iron chain across the Hudson at this point because British ships would have to slow down to navigate the S-turn, making them susceptible to cannon fire.  The British never tested the chain, and their Naval forces remained separated in Canada and New York.  Due to its success on the western point of the river, the United States Military Academy has been commonly referred to as "West Point," since the military academy became the first training institution for U.S. Army officers in 1802.
Por que a Academia Militar dos Estados Unidos se chama West Point?
A Academia Militar dos Estados Unidos é chamada de West Point porque está no ponto ocidental de uma virada em S no rio Hudson. Durante a Revolução Americana, o Exército Revolucionário estendeu uma cadeia de ferro através do Hudson neste ponto porque os navios britânicos teriam que desacelerar para navegar na virada em S, tornando-os suscetíveis a fogo de canhão. Os britânicos nunca testaram a cadeia e suas forças navais permaneceram separadas no Canadá e Nova York.
