The 10th Maine Infantry Regiment was mustered in for two years of service at Portland, Maine, on October 4, 1861, by then-Major Seth Eastman.^[1] It was mustered out on May 8, 1863, also at Portland. The regimental commander was Colonel George Lafayette Beal. The 10th Maine was a re-organization of the 1st Maine Infantry, a regiment primarily composed of men with two-year enlistments that was mustering out after completing three months of Federal service. Eight companies of the 1st Maine were retained in service, with Companies A and D replaced by newly recruited companies.^[2]

A fraction of the regiment consisted of three-year enlistees, who formed the three-company 10th Maine Infantry Battalion (Cos. A, B, and D) upon the discharge of the two-year enlistees on April 26, 1863.^[3] The 10th Maine Battalion served as headquarters guard for the XII Corps at the Battle of Chancellorsville and as part of the Army of the Potomac's provost guard at the Battle of Gettysburg.

The 10th Maine Battalion was detached from the XII Corps at Tullahoma, Tennessee, on February 29, 1864, to be amalgamated with the 29th Maine Infantry. On May 29, 1864, the battalion reached Morganza, Louisiana (aka Morganzia) and was dissolved to form Companies A and D of the 29th Maine, where the soldiers were again commanded by Colonel Beal who was appointed as commander of the 29th Maine.^[4]

The regiment's history, History of the 1st-10th-29th Maine Regiment, was written by Major John Mead Gould. The unit's flags are preserved in the Maine State Museum.^[5]
