The army will resume its march to-morrow, taking the Hagerstown road. General Jackson's command will form the advance, and after passing Middletown with such portion as he may select, take the route toward Sharpsburg, cross the Potomac at the most convenient point, and by Friday morning take possession of the Baltimore and Ohio Railroad, capture such of the enemy as may be at Martinsburg, and intercept such as may attempt to escape from Harper's Ferry.

General Longstreet's command will pursue the main road as far as Boonsborough, where it will halt with reserve, supply, and baggage trains of the army.

General McLaws, with his own division and that of General R. H. Anderson, will follow General Longstreet. On reaching Middletown he will take the route to Harper's Ferry, and by Friday morning possess himself of the Maryland Heights and endeavour to capture the enemy at Harper's Ferry and vicinity.

General Walker with his division, after accomplishing the object in which he is now engaged, will cross the Potomac at Cheek's Ford, ascend its right bank to Lovettesville, take possession of Loudoun Heights, if practicable, by Friday morning, Key's Ford on his left, and the road between the end of the mountain and the Potomac on his right. He will as far as possible coöperate with generals McLaws and Jackson and intercept the retreat of the enemy.

General D. H. Hill's division will form the rearguard of the Army, pursuing the road taken by the main body. The reserve artillery, ordnance and supply trains, etc., will precede General Hill.

General Stuart will detach a squadron of cavalry to accompany the commands of generals Longstreet, Jackson, and McLaws, and, with the main body of the cavalry, will cover the route of the army, bringing up all stragglers that may have been left behind.

The commands of Generals Jackson, McLaws, and Walker, after accomplishing the objects for which they have been detached, will join the main body of the army at Boonsboro or Hagerstown.

By command of General R. E. Lee,

R. H. Chilton,
Assistant Adjutant-General.
