10th Maine Volunteer Infantry Regiment

The 10th Maine Infantry Regiment was mustered in for two years of service in Portland, Maine on October 4, 1861. It was mustered out on May 8, 1863. The regimental commander was Colonel George Lafayette Beal.

A fraction of the regiment consisted of three year enlistees, who formed the three-company 10th Maine Infantry Battalion upon the discharge of the two year enlistees. The 10th Maine Battalion served as the Army of the Potomac's provost guard at the Battle of Gettysburg.

The soldiers of the 10th Maine Battalion were later amalgamated with the 29th Maine Infantry on November 13, 1863 to form Companies A and D of the 29th Maine, where they were again commanded by Colonel Beal who was appointed as commander of the 29th Maine.

The regiment's history, The History of the 1st-10th-29th Maine Regiment, was written by Major John Mead Gould.
