Battery construction started in 1893, was completed in 1898 and transferred to the Coast Artillery for use 8 Jun 1898 at a cost of $ 106,757.08. Deactivated in 1942.

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 Dehart's guns were listed to be dismounted for service abroad but were ordered remounted before they could be shipped.

World War II (1941-1945)

Battery DeHart was obsolete at the beginning of World War II. The guns and carriages were ordered salvaged on 15 Dec 1942.
