Endicott Period (1890-1910)
Part of the Harbor Defense of Portland, Maine.
Originally built as an Endicott Period concrete coastal gun battery with two 10" M1888MI guns mounted on M1894MI Disappearing carriages and one 10" M1888MII mounted on an M1896 Disappearing carriage. This was a two-story battery with the guns located on the upper level and the magazines below. Shells were moved from the magazine level to the gun loading platform by three back delivery Taylor-Raymond shell hoists that were accepted for service 23 Aug 1907. Three Type C powder hoists were accepted for service on 14 Oct 1912. The disappearing carriages were fitted with electric retraction motors. Electrical power was furnished by the emplacement power plant and the central 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. The guns of Battery Sullivan were removed for service abroad and shipped off in 1918 but they were replaced in 1919 with different serial numbered guns.
Battery Sullivan was declared no longer required by the Secretary of War on 17 May 1932 but the guns and carriages were not ordered scrapped until 4 Nov 1942. The battery structure was used during World War II as a Harbor Defense Control Post (HDCP).
Part of Fort Williams Park, Cape Elizabeth, Cumberland County, Maine. No period guns or mounts in place.
