Tuesday, 7th—We kept on the march last night till 1 a. m., when we stopped in bivouac. The men were all very tired, yet were willing and anxious to go on if only they could capture Price, or even a part of his army. Leaving our bivouac at 8 o’clock this morning, we again started after Price. We soon came upon the rebels and shelled their rear guard almost all day. We took a great many prisoners. It is reported that they are breaking up into small bands and getting away through the timber and are scattering in every direction.
