|
Battery Wallace (2) (1921-1948) - Battery Wallace was a reinforced concrete, World War I 12 inch coastal gun battery on Fort Barry, Marin County, California. The battery was named in G.O. 63, 12 May 1919, after Colonel Elmer J. Wallace, Coast Artillery Corps, who died 5 Nov 1918 at Somlly, France. Battery construction started in 1917, was completed in 1921 and transferred to the Coast Artillery for use 24 Jun 1921 at a cost of $ 273,464.41. The Battery was later casemated in 1942-1943 at a cost of $ 758,241.67 and re-transferred 16 Nov 1943. Deactivated in 1948.
World War IPart of the Harbor Defense of San Francisco. Originally built as a concrete coastal gun battery with two 12" M1895MI guns mounted on M1917 Barbette carriages positioned on open concrete pads that provided a 360 degree (ARF) field of fire. The carriages were built to provide a 35-degree maximum elevation with a corresponding increase of maximum range to 29,300 yards. The two concrete gun platforms were constructed 1917-1918 and the magazines and service rooms were constructed 1919-1921. No hoists were required as the shells and powder were stored on the same level as the loading platform. The guns were mounted in November 1917. The magazine and service rooms were located in a concrete structure between and in back of the gun positions. The roof of the structure was 11' of concrete reinforced with I beams and that was covered with not less than 5' of earth. There were four 12' 6" by 50' powder rooms and three shell rooms, 1 large shell room 10' by 101' and two smaller ones 13' by 32'. A power room was located between the two smaller shell rooms. An overhead trolly system brought the 2,400-pound projectiles to each of the gun emplacements. There were two BC Stations on the top of the building and two plotting rooms below At a proof firing in 1928, gun #68 was damaged and was returned to the Watervliet Arsenal 7 Dec 1928. The replacement tube #75 was shipped from Fort Hancock (2) to Fort Barry on 10 Jan 1929. M1895MIA4 gun tubes #44 and #63 were shipped from Watervliet Arsenal to Battery Wallace as spares 20 Apr 1939 and retained at the battery. The gun records indicate that all of the guns were converted to the MI-A4 variety although the December 1943 RCW indicates that the two mounted guns are MI variety and the two spares are MI-A2 variety.
World War IIEarly in World War II (7 May 1942), a directive was issued to casemate Battery Wallace to protect it from enemy aircraft. The existing gun emplacements were used as well as much of the existing magazine and service rooms but the whole complex was covered and the connecting passageways between the gun emplacements and the magazine were converted to concrete tunnels. Large concrete casemates were built around the gun emplacements, a new power room was built, rear entrances to the gun position casemates, gas-proof doors were added and prison type fold down bunks were installed in the new corridors for the ready crews. The completed modifications were accepted on 16 Nov 1943.
Current StatusPart of the Golden Gate Recreation Area (GGNRA) administered by the National Park Service. No gun or mounts in place.
