7th New York Heavy Artillery Regiment

The 7th New York Heavy Artillery Regiment, U.S. Volunteers was a heavy artillery regiment that served in the Union Army during the American Civil War. The regiment operated as both heavy artillery and infantry beginning in December 1862 while serving in the defenses of Washington, D.C., and continued in both capacities until the end of the war.

Service


The regiment was organized at Albany, New York, as the 113th New York Volunteer Infantry and mustered on August 18, 1862, for three years service under the command of Colonel Lewis O. Morris. Because heavy artillery regiments were needed for the defenses of Washington, D.C., the regiment was converted from infantry on December 10, 1862, and became the 7th New York Heavy Artillery on December 19, 1862. Two additional companies were organized and mustered on August 6, 1863, and January 19, 1864.

The regiment was attached to Defenses North of the Potomac River, September 1862 to February 1863. 2nd Brigade, Haskin's Division, XXII Corps, Department of Washington, to May 1864. Tyler's Heavy Artillery Division, II Corps, Army of the Potomac, May 18–29, 1864. 4th Brigade, 1st Division, II Corps, to November 23, 1864. 2nd Brigade, 1st Division, II Corps, to February 22, 1865. Defenses of Baltimore, Maryland, VIII Corps, Middle Department, to August 1865.

The 7th New York Heavy Artillery mustered out of the service August 1, 1865.
