Lt. Alexander Crawford Jr., ca. 1864
Lt. Crawford was the commanding officer of Co. G, 31st Maine Volunteers. This was his second tour of duty, having previously served a nine-month enlistment with the 21st Maine Volunteers.
This photo was probably made in the summer of 1864, near the time of the siege of Petersburg, Virginia. Crawford made the rank of sergeant in May of that year and was seriously wounded in July. Therefore, this photo must have been taken between those two dates.
After partially recovering from his wound, he rejoined his regiment in February of 1865. Soon after this, he was commissioned a lieutenant and assumed command of Co. G, 31st Maine Volunteer Infantry, a post that he held until his unit was mustered out in August 1865.
