The singular purpose of the soldier was to fight a battle and win. There were a variety of small arms used during the Civil War. The average infantryman carried a muzzle-loading rifle-musket manufactured in American arsenals or one purchased from foreign countries such as England. The bayonet was an important part of the rifle and its steel presence on the muzzle of the weapon was very imposing. When not in battle, the bayonet was a handy candle holder and useful in grinding coffee beans. The typical rifle-musket weighed eight and one-half pounds and fired a conical shaped bullet called the Minie Ball. Bullets were made of very soft lead and caused horrible wounds which were difficult to heal. The artillery was composed of both rifled and smoothbore cannon, each gun served by a crew of fourteen men including the drivers. The role of the artillery was to support the infantry while the infantry role was to either attack or defend, depending on the circumstances. Both branches worked together to coordinate their tactics on the field of battle. Cavalrymen were armed with breech loading carbines, sabers, and pistols. Cavalry was initially used for scouting purposes and to guard supply trains. The role of mounted troops had expanded by the time of Gettysburg, with cavalry divisions acting as skirmishers and fighting mounted and on foot in pitched battles such as Brandy Station, Virginia on June 9, 1863. Other branches of the armies included the signal corps, engineers, medical and hospital corps, as well as supply organizations including the quartermasters.
