Fort Rosecrans
Fort Rosecrans (1852-1959) - Established 26 Feb 1852 as the Fort at Ballast Point and renamed Fort Rosecrans in 1899 after Maj. Gen. William S. Rosecrans. Located in San Diego County, California. The military reservation was transferred to the U.S. Navy Department 1 Jul 1959.
Fort Rosecrans History
The initial fortifications were planned for Ballast Point about the location of the old Spanish Fort Guijarros but actual construction of earthworks didn't begin until 1873. Plagued by a chronic lack of funds, the first batteries weren't completed until 7 Feb 1898.
Endicott Period (1890-1910)
Part of the Harbor Defense of San Diego. Established to protect the entrance to San Diego Harbor.
Four Endicott Period Batteries were constructed beginning in 1897 and two of them remained active through 1943.
Initial post construction was completed in 1904 as a small two company coastal fort. Officers row contained the commanding officer's quarters and four sets of duplex company grade officer quarters. Two 116 man barracks and two sets of duplex NCO quarters housed the enlisted men. A guardhouse, hospital, administration building and various support buildings completed the basic post. A small expansion took place between 1909 and 1911 with the addition of more NCO quarters, a PX/gym and a morgue.
The post was laid out along San Diego bay with the major buildings all in a row facing the bay. The traditional central parade was not possible because of the slope of the land. The gun batteries were all situated to the south of the post buildings.
