The records of the Military Department consist primarily of materials documenting the history of Connecticut's militia, national guard units, and the service of Connecticut volunteers during the Civil War. The records contain extensive materials documenting the work of the Adjutant General, 1792-1807, including general orders, resignations and discharges, correspondence, militia returns, pensions, and reports and rosters. RG 013 also holds records of Civil War volunteer regiments, courts martial, bounty and pension files, and fragmentary pre-Civil War records of militia regiments. The Civil War regimental records include enlistment papers, muster rolls, monthly returns, and muster out rolls. In addition, records exist for the First Company, Governor's Foot Guard, and Connecticut's Civil War "Colored" 29th, 30th, and 31st Regiments. Extensive documentation on various units of the Connecticut National Guard are included, consisting of records on specific regiments, the Connecticut Home Guard, and of artillery, naval, and air units. The bulk of the materials cover the period after 1820, although some records document the War of 1812 period.
