may deem best. It seems to me that they should connect with your right flank. I think that the troops sent here from Harper's Ferry and a part of the forces now in Baltimore. I am awaiting an answer from my dispatch, sent through General French this morning, in regard to re-enforcing him as above indicated. So long as your movements cover Baltimore and Washington from Lee's main army, they are in no danger from any force the enemy may detach for a raid. We have heard nothing from you since yesterday morning, and are anxious to learn more of the results of your brilliant fighting.

HEADQUARTERS ARMY OF THE POTOMAC,
Gettysburg, July 6, 1863-2 p. m. (Received 9. 20 p. m.)
Major General H. W. HALLECK,
Yesterday I sent General Sedgwick with the Sixth Corps in pursuit of the enemy toward Fairfield, and a brigade of cavalry toward Cashtown. General Sedgwick's report indicating a large force of the enemy in the mountains, I deemed it prudent to suspend the movement to Middletown until I could be certain the enemy were evacuating the Cumberland Valley. I find great difficulty in getting reliable information, but from all I can learn I have reason to believe the enemy is retreating, very much crippled, and hampered with his trains. General Sedgwick reported that the gap at Fairfield was very formidable, and would enable a small force to hold my column in check for a long time. I have accordingly resumed the movement to Middletown, and I expect by to-morrow night to assemble the army in that vicinity. Supplies will be then provided, and as soon as possible I will cross South Mountain, and proceed in search of the enemy. Your dispatch requiring me to assume the general command of the forces in the field under General Couch has been received. I know nothing of the position or strength of hi command, excepting the advance under General Smith, which I have ordered here, and which I desire should furnish a necessary force to guard this place while the enemy is in the vicinity. A brigade of infantry and one of cavalry, with two batteries, will be left to watch the enemy at Fairfield, and follow them whenever they evacuate the gap. I shall send general instructions to General Couch to move down the Cumberland Valley as far as the enemy evacuates it, and keep up communications with me; but from all the information I can obtain, I do not rely on any active co-operation in battle with this force. If I can get the Army of the Potomac in hand in the Valley, and the enemy have not crossed the river, I shall give him battle, trusting, should misfortune overtake me, that a sufficient number of my force, in connection with what you have in Washington, would reach that place so as to render it secure. General Trimble, of the Confederate army, was to-day found wounded just outside of Gettysburg. General [J. L.] Kemper was found mortally wounded on the road to Fairfield, and a large number of wounded, estimated as several thousand. General Heth, Wade Hampton, Jenkins, and Pender are reported wounded.
