1st Delaware Infantry Regiment

The 1st Regiment Delaware Volunteer Infantry was a United States volunteer infantry regiment raised for Union Army service in the American Civil War. For part of the war, it was a part of the famed Gibraltar Brigade.

May - August 1861
When the Civil War began in April 1861, there were only about 16,000 men in the U.S. Army, and many Southern soldiers and officers were already resigning and joining the new Confederate States Army. With this drastic shortage of men in the army, President Abraham Lincoln called on the states to raise a force of 75,000 volunteers for three months to put down the insurrection in the South. Accordingly, the 1st Delaware was raised at Wilmington, Delaware on May 22, 1861 and mustered into Federal service on May 28. The regiment comprised 37 officers and 742 enlisted men under the command of Colonel Henry H. Lockwood. The regiment was attached to the command of Major General John Dix ('Dix's Command", Department of the Potomac) and assigned to duty along the line of the Philadelphia, Wilmington and Baltimore Railroad. The regiment mustered out on August 30, 1861.

September 1861 - July 1865
The war proved to be longer and larger than anyone had expected, and on July 22, 1861, the United States Congress authorized a volunteer army of 500,000 men. A "new" 1st Regiment of Delaware Volunteers was raised at Wilmington, Delaware between September 10 and October 19, 1861. The regiment served throughout the war and suffered 12 officers and 146 enlisted men killed and mortally wounded, and 118 enlisted men killed by disease. The regiment mustered out of Federal service on July 12, 1865 with 37 officers and 846 enlisted men under the command of Colonel John W. Andrews.
