Although expecting every moment to be put into action and held strictly in line of battle, yet the men were able to take some rest and make the most of their rations. Somewhere near 4 p. m. a sharp cannonade, at some distance to our left and front, was the signal for a sudden and rapid movement of our whole division in the direction of this firing, which grew warmer as we approached.
