General HALLECK:

General Milroy has cut his way through, and arrived at Harper's Ferry. His losses are reported considerable, with great damage to the enemy. Hi will telegraph soon. Tyler brought troops from Martinsburg to Maryland Heights, and is in command there. Have sent Kelley around to New Creek, to concentrate troops on western portion of railroad. Ordered Averell to concentrate at Grafton, with a view to covering approaches to Wheeling, and to come eastward, perhaps also to New Creek, to hold as much as possible of the railroad eastward toward Martinsburg.

Major T. T. ECKERT:

Generals Milroy and Elliott are now here. The troops are coming in by regiments and squads. Milroy thinks his killed, wounded, and missing will not exceed one-third of his force. I am sending everybody over to Maryland Heights. Demoralized troops, such as those from Winchester, are not the troops to defend important position with. We shall do what we can. Our effective force here, independent of General Milroy's men, is not over 4, 000.

DAN. TYLER,

Brigadier-General.
