  ## Detailed service
  
  This regiment was organized at Baltimore during the months of July and August, 1862, with the exception of Co. E, which was raised in Carroll County. It consisted of nine companies and was assigned to the famous Maryland Brigade, which was commanded by Gen. John R. Kenly, the first colonel of the 1st Md. infantry, and remained with the brigade throughout the war. On Sept. 18, 1862, it received marching orders and hurried to join the Army of the Potomac, then at Antietam, and arrived there in time to assist in expelling Lee's army from Maryland. It spent the winter of 1862-63 on Maryland Heights, opposite Harper's Ferry, where it remained until April, 1863, when it was sent to West Virginia to repel the raids of Gens. Imboden and Jones. The conduct of the Maryland brigade in this campaign elicited a complimentary letter from Gen. B. F. Kelley, commanding the 1st Division, 8th Corps, to Gen. Kenly. On June 30, 1863, the regiment, with the Maryland Brigade, marched to Frederick City, where it was attached to Gen. French's division, which was engaged in keeping open the communications between Washington and the Army of the Potomac. After the Battle of Gettysburg the regiment, with the 1st and 8th Md. Infantry, made a forced march to Harper's Ferry and recaptured that place on July 6, after a sharp fight. During the summer and fall of 1863 it was with Gen. Meade's army in Eastern Virginia, taking part in a number of engagements. In March, 1864, the Maryland Brigade became the 3rd Brigade, 2nd Division, 5th Corps, and with that command was in the campaign from the Rapidan to the James, participating in the battles of the Wilderness, Spotsylvania Court House, the North Anna River, Totopotomy, Bethesda Church, the Siege of Petersburg, Hatcher's Run, Weldon Railroad, and various lesser engagements. While in service it marched 1,089 miles and traveled by rail 649 miles. It was mustered out at Arlington Heights, Va., May 31, 1865.
