At about 9 oclock the force was withdrawn from the front, with the exception of the First North Carolina and Forty-eighth Georgia Regi- ments, which held the advanced line of pickets. We captured altogether 1 captain and 10 privates, 4 of the latter being wounded. Colonel Smith recovered 20 stand of arms from the battle-field. Our loss consisted of Third Lieutenant Ware and Private S. S. Han- kin captured and Private Darden Johnson killed, of the cavalry, and 2 privates killed and 4 wounded of the Forty-fourth Georgia Regiment. Some 0 of the First North Carolina Volunteers were missing last night, having been lost in the swamp. All but 3, however, have returned, and it is hoped that all will be present before night-fall.
