Wednesday, 15th—We are once more getting settled in camp. Our duties are not as laborious as they were at Bolivar and Iuka. We have begun the building of forts and rifle-pits, close in, all around Corinth, so that a small force can hold the place. We are pulling down some of the vacant houses to make room for fortifications. But the fortifications will not be on as grand a scale as those built here during the summer. They will be smaller, too, than the fortifications which protected us during the battle here.
