This battery was the first of the six batteries to be completed and the only one to be in service during the Spanish-American War. Each of the four eight-inch guns on Battery Brumby weighed 32,000 pounds and had a range of about ten miles. These guns were mounted on disappearing carriages. After firing, the recoil would lower the gun back and down below the protective parapet. The operation of the battery required four officers and 157 men. The guns were dismantled and shipped to France during World War I.
