Endicott Period

Part of the Harbor Defense of the Delaware.

Originally built as an Endicott Period concrete coastal gun battery with two 12" M1888 guns and one 12" M1888MII gun all mounted on M1896 disappearing carriages. The three gun emplacements of this battery were built together with the three 10" gun emplacements of Battery Harker as one large battery.

Battery Arnold was a two-story battery with the guns on the upper level and a magazine for each gun on the lower level. Three Taylor-Raymond back delivery projectile hoists moved the shells from the magazine level to the gun loading platform. The shell hoists were transferred for use on 27 May 1907. No powder hoists installed. Electric power for the battery was furnished by an internal power plant.

Battery Arnold Plan

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 gun tubes of Battery Arnold were not affected by the World War I redistribution or the 1920 disarmament program.

World War II

The abandonment of Battery Arnold was authorized 31 Aug 1943 and the guns and carriages of Battery Arnold were ordered salvaged 9 Dec 1943.

Current Status

Part of Fort Mott State Park. No period guns or mounts in place.
