During the Civil War, he served as a Private in Company D of the 54th Massachusetts Volunteer Infantry of the Union Army, the first regiment in the United States made up entirely of enlisted men of color. He was about 24 years old, single and working as a laborer when he enlisted on 25 March 1863 in Harrisburg, Pennsylvania. He died of heart disease on 7 June 1863 in Beaufort, South Carolina.
Note: There are at least two other George Scotts enlisted in the 54th.
