Gunner's Haversack
Artillery crews used this leather bag to protect and carry the rounds for firing the gun. Artillery crews usually consisted of seven men who ran the drill for firing the cannon. The number five man on an artillery crew would recieve the round from the number six man stationed at the limber. Then the number five man would carry the round inside of the haversack, running to the muzzle of the cannon, before giving it to the number two man who placed it inside the muzzle.
