We got our equipments today. Our guns are the old-fashioned muskets made by working over the old flintlock gun, so as to use a cap in place of the flint. The musket is loaded with a cartridge containing powder, ball, and three buckshot in front of the ball. Each man is to carry forty rounds or more of ammunition all the time.
