Battery Slaughter Plan

World War I

Declared "as of insufficient military value to warrant provision of manning personnel and ammunition therefor" on 27 Oct 1915 along with Battery Wagner and Battery Howe. On 24 Aug 1917 the three 8" guns of Battery Slaughter were ordered dismounted for use abroad and on 18 Jul 1918 they were reported as having been transfered for service abroad. The gun cards indicate that the guns were shipped to the Watervliet Arsenal 31 Dec 1917 for the A1 modifications for service abroad, none were shipped overseas and all were salvaged in 1946.
