Should there be an attack upon you in force you will back on Maryland Heights, by way of Shepherdstown. This maynot become a necessity for a day or so, but by day after to-morrow he anticipates it will become a necessity. But hold on to the railroad to the last moment; it is important to get our supplies from Cumberland to-morrow evening.

Lieutenant and Aide-de-Camp.
