Endicott Period

Originally built as an Endicott Period concrete coastal gun battery with one 6" M1897MI gun mounted on an M1898 carriage and one 6" Armstrong gun mounted on an Armstrong pedestal mount. This is a two story gun battery with the guns located on the upper level and the magazines and utility rooms located below. The battery is designed for two different 6" guns and mounts, one pedestal mounted Armstrong gun and one disappearing gun carriage. The pedestal mounted Armstrong gun was removed in 1904 but the disappearing gun remained until 1944. An electric powered Hodges back delivery shell hoist was used to bring the shells up from the magazine level to the gun loading platform level. Electrical power was furnished by the Battery Jasper power plant.

World War I

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 one remaining 6" gun at Battery Logan was not affected by the World War I redistribution or the 1920 disarmament program.

World War II

The remaining M1897MI gun and M1898 carriage were ordered salvaged 9 Mar 1944.

Current Status

This battery is very overgrown and looks to be in poor condition. No period guns or mounts in place.

Location: Fort Moultrie, South Carolina
