Fort Hamilton played especially significant roles in the Civil War as well as both World Wars. It was key in the areas of defense, training and deployment in those wars. Many expected that the base would be closed in 1995 as part of Congress's Base Realignment and Closure (BRAC) Commission. However, the base was not recommended for closure and continues to serve as both an active base and a training center for for Army Reserve and National Guard units.
Today, the United States Army Garrison Fort Hamilton is the only active
military base in the city of New York. As such, it has served as a
critical base of operations in the aftermath of Hurricane Sandy, the
terrorist attacks of September 11th, and many other natural disasters and threats. The base serves a joint federal and state mission, providing ready soldiers for the active army and the state of New York.
