burg, and drove them into town, creating great commotion in a large force of the enemy, mostly infantry - about 2, 000. Counted a train of twenty-four wagons, and three camps, of Sibley, and wall tents ; section of artillery. Scouts on Hancock road ran in enemy's pickets on Sidling Hill Creek, and observed camps. Citizens said there were eighteenth companies of infantry, and column of cavalry a mile long, 8 miles this side of Hancock. I would feel much better if I had necessary supplies and artillery . Why are the latter delayed?
