40th New Jersey Infantry Regiment

The 40th New Jersey Infantry Regiment was an infantry regiment raised in the state of New Jersey during the American Civil War. It was the last such unit the state raised for the conflict.

Organization
The first company of the 40th New Jersey Infantry Regiment was organized on October 23, 1864, but since the low enlistments numbers the companies were individually sent to the front, and were temporarily attached to the 4th New Jersey Volunteer Infantry in the First New Jersey Brigade. It was officially organized and mustered in as a whole on March 10, 1865, when the last company was sent to the front. Owing largely to high bounties paid out and a smaller pool of available men of age since the war was in its later days, the unit suffered heavy desertion rates - the highest of any New Jersey infantry regiment. Its commander, Colonel Stephen Rose Gilkyson, had previously commanded the 6th New Jersey Volunteer Infantry as a lieutenant colonel, and had several years of combat field service under his belt. Likewise, most of the 40th's officer corps were combat veterans from previous New Jersey regiments. Due to the haphazard way the unit was organized, many officers served in their duty in the field long before they were officially mustered in.

Field service
Although the unit as it existed at the time was present at the Battle of Hatcher's Run near Dabney's Mills on February 5–7, 1865, the 40th New Jersey participated in their first and last battle on April 2 at Petersburg, where it participated in the final Union army assaults on Confederate entrenchments. There the unit suffered 23 wounded (2 of whom died later). Private Frank E. Fesq of Company A captured the battle flag of the 18th North Carolina Infantry during the assault, earning him the Medal of Honor.

The regiment remained in occupation duty after the Confederate surrender, then was mustered out at Hall's Hill, Virginia, on July 13, 1865.
