General Ovarial will cross with his division at Beverly Ford, followed by General Gregg, with his division. General Buford, with his Reserve Brigade will cross at the ford in the vicinity of the Rappahannock railroad bridge simultaneously with General Avarell. As soon as General Ovarial and General Buford are across the river, and both have formed their commands a short distance beyond the river, Avarell will push on to Culpeper Court-House, keeping to the right of the railroad, if possible to transport his artillery, or, if there is no road leading along the right and near the railroad, then by the nearest road. Gregg will cross the river as soon after Ovarial as possible, and follow him, well closed up on his rear.

If there should be a route practicable for artillery, and running parallel to the route pursued by Avarell, Buford will follow it, provided it does to the route pursued by Ovarial, Buford will follow it, provided it does not lead too far to the left. If there is no such route, the artillery of Buford will be sent to the rear of Gregg, and the Reserve Brigade will march through the country, irrespective of roads, keeping at such a distance from Avarell as to give room for Avarell to from his division front into line of battle. Avarell will move on the direction of the enemy, who is supposed to be a mile or so this side of Culpeper Court-House. In case Avarell comes upon the enemy, Gregg will from his division at once, and hold it in readiness to move to the right of Avarell's division, and Buford will act, looking to the left, and Davis will endeavor to turn the enemy's left flank. If the enemy is encountered, he will be attacked at once and with the utmost vigor, pouring in upon him every available man, excepting a limited in each command.
