Major General J. HOOKER,

GENERAL: As you will probably have breast-works constructed to-night, and as the enemy has been repulsed along the whole line in his attack of to-day, the major-general commanding directs that you press him strongly with skirmishers in the morning, for the purpose of ascertaining what has become of him, and of ascertaining his intentions.

The same has been ordered for other corps of the army.
