Endicott Period (1890-1910)

Part of the Harbor Defense of San Francisco.

Battery Stotsenburg was originally built with sixteen 12" M1890MI rifled steel mortars on M1896MI mortar carriages in a concrete battery with four mortar pits (A-D) in a straight line. In 1906 mortar pits C and D were renamed Battery McKinnon and pits A and B retained the Battery Stotsenburg name. This was a single level mortar battery with the mortar loading platforms on the same level as the magazines. Shells were brought from the magazines by shot carts. No shell or powder hoist were provided or needed. The concrete magazines were built between the mortar pits and covered with some 20' of earth. Electrical power was furnished from a central power plant and a backup emplacement power plant.

World War I (1917-1918)

The U.S. entry into World War I resulted in a widespread removal of large caliber coastal defense gun tubes for service in Europe. Many of the gun and mortar tubes removed were sent to arsenals for modification and mounting on mobile carriages, both wheeled and railroad. Most of the removed gun tubes never made it to Europe and were either remounted or remained at the arsenals until needed elsewhere. As of 18 Jul 1918, four 12" mortars and carriages from Battery Stotsenburg were listed for transfer to Grays Harbor Military Reservation (j19). This listing was suspended on 30 Apr 1919 pending further study of the use of railroad artillery in the defenses of Grays Harbor Military Reservation (m10). The mortars were never shipped to Grays Harbor Military Reservation and Battery Stotsenburg seems to have kept all eight mortars until the start of World War II.

World War II (1941-1945)

The mortars of Battery Stotsenburg were obsolete at the beginning of World War II. They were all ordered scrapped 19 Nov 1942 during the first large scale World War II scrap drive.

Current Status

No period guns or carriages in place.
