History


Civil War

Military use of the island dates from 1861, when the 3rd Regiment ( 63rd New York Infantry) of the Irish Brigade established Camp Carrigan. In 1862, Davids Island was leased by the U.S. Government. This marked the first use of Davids Island by the

Late 19th century through 1916

As the post on Davids Island grew, in the 1880s the Army invested in new brick construction of more than 20 new buildings, including officers' quarters, enlisted men's barracks, mess halls, hospital buildings, and support facilities.Fort Slocum at FortWiki.com

, and Davids Island became part of its system of defenses. Between 1891 and 1904, artillery batteries were erected at three places on the eastern half of the island: Battery Practice near the southeastern shoreline, with 1870s-era weapons for training personnel for older forts, the state-of-the-art Abbot Quad heavy mortar batteries, Haskin and Overton, mounting a total of 16 breech-loading 12-inch mortars, at the southeast end of the island; and two adjoining medium-range breech-loading rifled gun batteries, Fraser and Kinney, on the northeastern shore.

Battery Kinney had two 6-inch M1900 guns on pedestal mounts, and Battery Fraser had two 5-inch M1900 guns on pedestal mounts. (Despite the presence of mis-captioned postcards, including those in the New Rochelle Public Library, there were never large-caliber breech-loading disappearing guns placed at Davids Island.)Berhow, p. 208 Battery Haskin was named for Joseph A.

stations in the country, processing 100,000 soldiers per year and serving as the recruit examination station for soldiers from New York, New Jersey, Pennsylvania and the New England states. Between 1917 and 1919, over 140,000 recruits passed through the post. Recruit Week in December 1917 brought so many recruits to Fort Slocum that an overflow had to be housed in New Rochelle. Fort Slocum's guns were dismounted and transferred to other uses beginning in 1917. Battery Kinney's 6-inch guns were moved to Fort Tilden. Battery Fraser's 5-inch guns were dismounted, probably for potential service on field carriages on the Western Front. Records do not indicate if these guns were sent to France. In 1919 Fort Slocum was totally disarmed. Its 16 mortars were removed and possibly became railway artillery.

World War II

On 16 May 1941, as war raged in Europe, Fort Slocum became part of the New York Port of Embarkation, becoming a staging area for troops moving overseas. Fort Slocum also trained cadre to set up other staging areas in Greater New York, such as Camp Kilmer and Camp Shanks in 1941 and 1942. Fort Slocum hosted the Atlantic Coast Transportation Officers' Training School, acquainting former civilians from the transportation industries with the Army. The fort was a key element of the Army's

By early 1944 the need to ship troops to Europe had lessened, and a policy of rotating troops in the US who hadn't seen action to overseas battlefields and the reverse was instituted. Battle-hardened soldiers returning from Europe were put through a "Provisional Training Center" at Fort Slocum to re-acquaint them with the stateside Army, with its surplus of proper military appearance, courtesy, and discipline, along with its deficit of actually shooting Germans. In May 1944 Private Willie Lee Duckworth of Sandersville, Georgia devised the famous "Sound off, one, two"

After closure

Fort Slocum was deactivated on November 30, 1965. During the decades that followed, the facilities of the former Army post were neglected and deteriorated severely and continued to occupy Davids Island into the beginning of the 21st century. The ruins were among the factors complicating redevelopment of the island. Beginning in 2004, however, Congress appropriated funds to remove the ruins through a Defense Department program that assists communities in reusing former defense facilities.
