Since the above was written I have received Colonel Harvey's report up to 7 a. m. He had received two rifle guns from General Banks besides those I sent. The enemy had thrown up another small earth-work, but had not opened upon our position since 11 a. m. yesterday. His guns were still in position.

With great respect, your obedient servant,.

CAMP SCOTT, September 11, 1861-p. m.

We yesterday marched 17 1/2 miles, reached the enemy's entrenched position in front of Carnifix Ferry, driving his advanced outposts and pickets before us. We found him occupying a strongly entrenched position, covered by a forest too dense to admit its being seen at a distance of 300 yards. His force was five regiments, besides the one driven in. He had probably sixteen pieces of artillery.

At 3 o'clock we began a strong reconnaissance, which proceeded to such length we were about to assault the position on the flank and front, when, night coming on and our troops being completely exhausted, I drew them out of the woods and posted them in the order of battle behind ridges immediately in front of the enemy's position, where they rested on their arms till morning. .
