FIRST REGIMENT
POTOMAC HOME BRIGADE INFANTRY.

THE First Regiment Infantry, Potomac Home Brigade, Maryland
Volunteers, was organized at Frederick City, Maryland, from Au-
gust 15 to December 13, 1861, to serve three years. Companies A,
B, D and I were recruited in Frederick County; Company C in Bal-
timore City; Companies E, F and H in Washington County; Com-
pany G in Baltimore, Carroll and Frederick Counties; Company K
in Baltimore City and Frederick County.

The 1st Regiment Potomac Home Brigade Infantry was assigned to General Banks'
Division, which was encamped in the vicinity of Frederick City, Maryland, during the
fall and winter of 1861-62.

In the spring of 1862 the 1st Regiment Potomac Home Brigade Infantry marched,
with General Banks' Division, up the Shenandoah Valley of Virginia as far as Winches-
ter, Virginia, but were subsequently assigned to the protection of the Baltimore and Ohio
Railroad in Maryland and Virginia. When General Banks' Division was driven out of
the Shenandoah Valley of Virginia in May, 1862, the 1st Regiment Infantry, Potomac
Home Brigade, was concentrated at Harper's Ferry, Va., to help protect that point from
capture.

On the 27th day of May, 1862, a detachment of the regiment had a skirmish with the
enemy whilst on a reconnoissance on Louden Heights, Virginia.

After the Federal troops again advanced up the Shenandoah Valley of Virginia, the
1st Regiment Potomac Home Brigade Infantry again resumed the duty assigned them of
protecting the line of the Baltimore and Ohio Railroad.

After the defeat of General Pope's Army in Northern Virginia and the advance of
General Lee's Army to the Potomac, the 1st Regiment Potomac Home Brigade Infantry
gallantly opposed the passage of the Potomac river at the fords on the Potomac, near the
mouth of the Monocacy.

The regiment was concentrated at Sandy Hook and marched thence to Harper's
Ferry, Va., where it took part in the defense of that point and was surrendered, with the
garrison, September 15, 1862.

The regiment having been paroled, marched to Annapolis, Maryland, and, when
exchanged, was subsequently assigned to duty on the Potomac in Southern Maryland.

During the Gettysburg campaign, the 1st Regiment Potomac Home Brigade Infantry
was assigned to General Lockwood's Brigade and the 12th Army Corps.

During the second day's fight at Gettysburg, July 2, 1863, it not only took part in
the battle on the right of the line at Culp's Hill, but was speedily transferred to that part
of the line where General Sickles' 3d Army Oorps of the Army of the Potomac had met
