"10th Maine Infantry Battalion" and similar unit names link here.


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. 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.

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. 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.

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.

    The companies of the 10th Maine were named as follows:

  • A - Saco
  • B - Portland Mechanic Blues
  • C - Portland Light Guard
  • D - Aroostook County
  • E - Portland Rifle Guard
  • F - Lewiston Light Infantry
  • G - Norway Light Infantry
  • H - Auburn Artillery
  • I - 2nd Co. Portland Rifle Guard
  • K - Lewiston Zouaves
  • The 10th Maine's band was Chandler's Band of Portland, Maine, which is still in existence.

    A pre-Civil War incarnation of the 1st Maine was formed in state service in 1854, and thus was older than any other Maine regimental organization. An historian of the 240th AAA (Anti-Aircraft Artillery) Group, a former Maine National Guard unit, has concluded that numerous subsequent Volunteer Maine Militia and Maine National Guard units, including the 10th Maine, were descended from the 1st Maine via the Portland Light Infantry company.


    Three monuments have been erected to the 10th Maine: one in the Culpeper National Cemetery in Virginia, one on the Cedar Mountain battlefield south of Culpeper, and one to the 10th Maine Battalion on the Gettysburg battlefield in Pennsylvania.
