_Light Pieces._—7, 8, 9, and 10 place themselves as in retreating slow;
13 gets a drag rope from 14, and gives it to 9 and 10, who lay the
center of it across the top of the traversing handspike, and then under
the trail hooks; 12 and 13 hook the traces of the horse brought up by
the driver to the ends of the drag rope; 15 turns the limber.
_Heavy Guns._—This is done in the same manner, but with two horses; 9
and 10 hook on the rear horse, and 12 and 13 the leader.
_Prepare for Action._—The same numbers undo what they have just done.
