Battery Croghan (1900-1946) - Battery Croghan was a reinforced concrete, Endicott Period 3-inch coastal gun battery on Fort San Jacinto, Galveston County, Texas. The battery was named in G.O. 194, 27 Dec 1904, after Colonel George Croghan, Inspector General U.S. Army, who died 8 Jan 1849. Battery construction started on 12 Jul 1899, was completed Jan 1900, and transferred to the Coast Artillery for use on 31 Mar 1900 at a cost of $ 32,988.75. The 1900 Galveston hurricane damaged the battery before it could be armed and it was repaired, armed, and re-transferred for use on 21 Aug 1911. Deactivated in 1946.

Endicott Period (1890-1910)

Part of the Harbor Defense of Galveston. The major mission of Battery Croghan was the protection of the shipping channel mine fields.

Originally built as an Endicott Period concrete coastal gun battery slated for two 15-pounder 3" Driggs-Seabury M1898 rapid-fire guns mounted on masking parapet carriages. The battery was completed and accepted early in 1900 before the 1900 Galveston hurricane but not armed. The battery structure survived the hurricane but was left exposed on its pilings. The battery was refurbished and the ramparts were rebuilt. When the time came to arm the battery, the more modern rapid-fire 3" M1903 guns mounted on M1903 pedestal mounts were emplaced. The carriages were transferred 9 Dec 1907 and the guns were mounted sometime before 1 Jan 1910.

A stand-alone mine casement that was destroyed during the 1900 Galveston hurricane was relocated and reconstructed on the right rear traverse of Battery Croghan. An exposed cable tunnel leads from the mine casement room of Battery Croghan to the water's edge.

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. Battery Croghan was not impacted by the World War I transfers.
