Battery East

 (1864-1896+) - Battery East was a masonry and earthworks, U.S. Civil War 42 pdr coastal gun battery on Fort Mason (2), San Francisco County, California. Battery construction started 1863, was completed in May 1864. Deactivated in 1896+.

U.S. Civil War (1861-1865)
Originally built in 1864 as a U.S. Civil War coastal gun battery with six 42 pounder banded rifles mounted on Iron carriages. Battery East was connected to a similar Battery West that mounted six 10" Rodman smoothbore cannons. Both batteries were earthworks fortifications backed with masonry walls and using front pintle mounts on wood platforms. Five small shell rooms were located between the guns and a single earth covered wooden magazine serviced the battery. All of guns were mounted on iron carriages. The original threat was perceived to be Confederate raiders entering San Francisco Harbor.

In 1888 all six of the 42 pounders rifles, carriages and wooden platforms were removed.

Endicott Period (1890-1910)
In 1891 a single modified 10" Rodman cannon with a rifled 8" insert was mounted on an iron carriage in the #6 emplacement of Battery East. This gun is shown as mounted in the 1896 battery plan. By 1903, the gun is no longer listed.
