Hills cover the approach to an artillery flank

The opposing battery sits in a dip that blocks its fire along one side of the battlefield. An advance on that route can use the hills as cover and avoid the more open approach through the trees. The plan is to reach the exposed flank and roll up the position from there. The force first settles into a defensive position because an early enemy charge could disrupt the maneuver. The sequence shows how terrain limits a gun position's line of sight and creates a covered route for an attack.
