If, in the contingency mentioned, you withdraw, sweep the valley clear of what pertains to the army, and cross the Potomac at the different points crossed by it.
You will instruct General Jones from time to time as the movements progress or events may require, and report anything of importance to Lieut.-Gen'l Longstreet, with whose position you will communicate by relays through Charlestown.
I send instructions for Gen'l Jones which please read. Avail yourself of every means in your power to increase the efficiency of your command, and keep it up to the highest number possible. Particular attention will be paid to shoeing horses, and to marching off of the turnpikes.
In case of an advance of the enemy, you will offer such resistance as will be justifiable to check him and discover his intentions; and, if possible, you will prevent him from gaining possession of the gaps.
In case of a move by the enemy upon Warrenton, you will counteract it as much as you can compatible with previous instructions.
You will have with the two brigades two batteries of horse artillery.
Very respectfully your obl. servt.
J. E. B. STUART,
Major Gen'l Com'dg.
Do not change your present line of pickets until daylight to-morrow morning unless compelled to do so.
