June 2, 1863.—Before Port Hudson, within easy cannon-range. This morning, we are not marching or fighting. We lie encamped in a wood, at the edge of a clearing, across which the rebel works are in plain sight, at the distance of a few hundred yards. The boys, who venture only a few rods from here to the edge of the clearing, find the shots of the rebel sharpshooters falling about them: their shells frequently strike in and about our camp. A piece of one has fallen within a few yards of me, breaking three muskets out of a stack that stood in the line. Day and night, our batteries are firing. Every few minutes, and at times more frequently, the earth-shaking roar of pieces of very large caliber makes the whole region tremble. Hardiker and I have built a little booth of boughs, whose roof may be taken off at any moment by a rebel missile. Two or three times last night, the earth flew to the right and left of the dead tree-trunk at whose foot we were resting.
