Armory building built in 1886 destroyed by fire in 1917
The Armory originally housed the 6th Separate Company (Troy Citizens Corps) Co. A, 2nd New York Volunteers who were previously housed in the Fulton Market Armory at River and Fulton Streets. The building was occupied by Co. D, 2nd Infantry Regiment, New York National Guard when it was destroyed by fire in January, 1917. The following month President Wilson called the unit to active duty after German declared the start of unrestricted submarine warfare. The call up was delayed several weeks while the unit waited for uniforms to replace those lost in the fire. The regiment entered World War I as the 105th Infantry, 27th Division. A new armory was built on 15th Street in 1920.
