West Point is the oldest continuously occupied military post in the United States. Located on the Hudson River in New York, West Point was identified by General George Washington as the most important strategic position in America during the American Revolution. Until January 1778, West Point was not occupied by the military. On January 27, 1778, Brigadier General Samuel Holden Parsons and his brigade crossed the ice on the Hudson River and climbed to the plain on West Point and from that day to the present, West Point has been occupied by the United States Army. It comprises approximately 16,000 acres (6,500 ha) including the campus of the United States Military Academy, which is commonly called "West Point".
