George Leonard Andrews

George Leonard Andrews (August 31, 1828 – April 4, 1899) was an American professor, civil engineer, and soldier. He was a brigadier general in the Union Army during the American Civil War and was awarded the honorary grade of brevet major general.

During the Civil War, Andrews served in a number of important commands, first as the colonel of the 2nd Massachusetts, a regiment which saw heavy action in the Battles of Cedar Mountain and Antietam, among other actions. Mentored by Maj. Gen. Nathaniel Prentice Banks, Andrews became part of Banks's staff and was assigned several command roles in the Army Department of the Gulf during the later years of the war.

After the war, Andrews pursued a variety of vocations, including service as a United States Marshal, before returning to the United States Military Academy at West Point as a professor until his retirement.
