   • 1809, William Duane, The American military library:

     At this command, the soldiers will carry their firelocks as they please, as prescribed in the soldier's drill, No 120, and are no longer required to march with the same step, or to observe silence ; the files will march at ease ; but they will be careful not to confuse the ranks, and the front rank must never pass before the guide, who is on the directing side, and that the two last ranks always preserve about three feet distance from each other.
