V. General Ferrero will move his division immediately after General Willcox's until he reaches our present advance line,where he will remain until the ground in his front is entirely cleared by the other three divisions, when he will move forward over the same ground that General Ledlie moved over; will pass through our line and, if possible, move down and occupy the village to the right.

VI. The formations and movements of all these divisions, together with their places of rendezvous, will be as near as possible in accordance with the understanding during the personal interviews with the division commanders. The headquarters of the corps during the movement will be at the fourteen-gun battery in rear of the Taylor house.
