structions to move forward before daylight
to-morrow and take up a position across the national road in the
enemy's rear, so as to cut off a retreat towards Xalapa. It may
be reinforced to-day if unexpectedly attacked in force, by
regiments, one or two taken from Shields' brigade of volunteers.
If not, the two volunteer regiments will march for that purpose
at daylight to-morrow morning, under Brigadier-General Shields,
who will report to Brigadier-General Twiggs, on getting up with
him, or the general-in-chief, if he be in advance.

The remaining regiment of that volunteer brigade will receive
instructions in the course of this day.

The first division of regulars (Worth's) will follow the movement
against the enemy's left at sunrise to-morrow morning.

As already arranged, Brigadier-General Pillow's brigade will
march at six o'clock to-morrow morning along the route he has
carefully reconnoitered, and stand ready as soon as he hears the
report of arms on our right, or sooner if circumstances should
favor him, to pierce the enemy's line of batteries at such point,
the nearer the river the better, as he may select. Once in the
rear of that line, he will turn to the right or left, or both,
and attack the batteries in reverse; or, if abandoned, he will
pursue the enemy with vigor until further orders.

Wall's field battery and the cavalry will be held in reserve on
the national road, a little out of view and range of the enemy's
batteries. They will take up that position at nine o'clock in the
morning.

The enemy's batteries being carried or abandoned, all our
divisions and corps will pursue with vigor.

This pursuit may be continued many miles, until stopped by
darkness or fortified positions, towards Xalapa. Consequently the
body of the army will not return to this encampment, but be
followed to-morrow afternoon, or early the next morning, by the
baggage trains of the several corps. For this purpose, the
feebler officers and men of each corps will be left to guard its
camp and effects, and to load up the latter in the wagons of the
corps. A commander of the present encampment will be designated
in the course of this day.

As soon as it shall be known that the enemy's works have been
carried, or that the general pursuit has be
