Battery Stotsenburg

 (1900-1942) - Battery Stotsenburg is a concrete Endicott Period 12" mortar battery located on Fort Winfield Scott (2), San Francisco County, California. Named after Col. John Stotsenburg, 6th U.S. Cavalry, a veteran of the Spanish-American War who was killed in the Philippines 23 Apr 1899. Work began on the Battery 6 Jul 1897, completed in 1898 and transferred for service 27 Apr 1900 at a cost of $130,188. Battery deactivated 1942.

Endicott Period (1890-1910)
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)
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.
