The 7th New Jersey Infantry Regiment was an American Civil War infantry regiment from New Jersey that served a three-year enlistment in the Union Army. It was mustered into federal service on September 3, 1861. The regiment trained at Camp Olden in Trenton, before being sent out to join the Army of the Potomac. In the spring of 1862, Company B was disbanded, and the enlisted men were assigned by transfer to different Companies in the Regiment.[1] On June 14, 1862, an independent company, commanded by Captain Edward G. Sloat, then at Alexandria, Va., was assigned to the Regiment, and designated Company B.[2]
