Commanding Sixth Corps:

GENERAL: The major-general commanding directs that you send to-night a force to the trains as guard, and to prevent teamsters from deserting and to assist the quartermasters in starting the trains promptly in the morning. This may be the same force which is to accompany the trains to-morrow or not, as you please. The Nineteenth Corps is two and a half miles from our headquarters, which are two miles from the town, so you can start in the morning at the hour indicated in the order and will not have to wait for the Nineteenth Corps to get out of the way.

Very respectfully, your obedient servant,
