Born in Marseille, France, Morse was a sergeant in Company "I" of the 62nd New York State Volunteers (Anderson Zouaves) and was awarded his Medal of Honor on January 14, 1890, for gallantry at the Battle of the Wilderness, Virginia, on May 5, 1864.

He was exchanged and at the time of the Battle of the Wilderness, May 5, 1864, was in command of his company, which numbered only 15, there being no commissioned officers left.

Despite falling back in perfect order the movement was interpreted by the enemy as a full retreat and started in pursuit.

Despite the pursuit the regiment maintained its order continually loading and facing about to fire while it fell back.

It was at this time that it was noticed that John H. L. Gilmore, one of the regiment's color-sergeants had fallen mortally wounded with the colours.

and Morse and Corporal Michael Ditzel of company "F" ran out from the line towards the wounded Gilmore and the advancing enemy.
