At the Battle of Antietam on 17 September 1862, the Union army employed 93 3-inch ordnance rifles while the Confederate army had 48. Among the Union army batteries, the 3-inch ordnance rifle was distributed as follows. One battery (Battery A, Maryland Light Artillery) – 8 guns, eight batteries – 6 guns, eight batteries – 4 guns, two batteries – 2 guns, and one battery – 1 gun. On the Confederate side, one battery (Milledge's Georgia) had 4 guns, 14 batteries had 2 guns, and 16 batteries had 1 gun.
