Organisation and Remusterings

90-Day Volunteers

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 Infantry Regiment 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.

Veteran Volunteers

On July 1, 1864, the 3 years enlistment would have ended and the regiment would be mustered out. Instead in July 1863 the men, still having nine months of their enlistment left, got the chance to reenlist for another 3 years from that date. On December 19, 1863, three quarters of the regiment reenlisted. The 1st Delaware was upgraded to veteran status as 1st Delaware Veteran Infantry Regiment. The 1st Delaware Infantry claimed to be first regiment in the Union to receive the coveted veteran status.

In April 1864 the 1st Delaware absorbed the remnants of the 2nd Delaware Infantry Regiment, a number of recruits and veterans with two complete companies.
