Endicott Period (1890-1910)
Part of the Harbor Defense of San Francisco.
Established in 1897 to guard the entrance to San Francisco Bay. Original Gun Batteries were Point Bonita, Point Diablo, Gravelly Beach, Lime Point Ridge, Cavallo, and Point Cavallo.
In 1890 plans were developed by a Board of Engineers for a series of eight Modern Endicott Period batteries on the north shore of the Golden Gate Strait, guarding the entrance to San Francisco Harbor. The Lime Point Military Reservation was renamed Fort Baker in 1897 and construction on the new batteries and the Fort infrastructure begun. Construction of permanent buildings began in 1901 with essential structures and by 1942 there were 159 buildings. Construction of the original planned eight gun batteries was complete by 1905. In 1904 the post was split into two forts, Fort Baker and Fort Barry. The dividing line between them was a North-South line originating at Point Diablo. The batteries that remained on Fort Baker are listed below.

World War I (1917-1918)
At the beginning of American involvement in World War I the guns of Battery Duncan and Battery Wagner (1) were removed for potential service overseas. After the war, one gun was removed from Battery Spencer and the post became inactive.
World War II (1941-1945)

In the buildup to World War II, Fort Baker was reactivated as a mine depot. Over three hundred underwater mines guarded the Golden Gate during World War II, tended by the Army’s “navy” of mine vessels berthed at Fort Baker.
Two gun batteries were build at Gravelly Beach to provide an anti-aircraft and anti-motor torpedo boat (AMTB) capability for the post and the remaining operational batteries. By 1945, only Battery AMTB - Gravelly Beach, Battery Yates and two 40mm guns were active, all for AMTB defense.
A large mobilization hospital was constructed starting in 1941 to supplement Letterman Hospital at the Presidio of San Francisco. The hospital grew from an initial twenty-five temporary WWII buildings to forty-five buildings by the end of the war. The hospital complex was located on filled in marsh land above Horseshoe Cove.
