Friday, 27th—We remained in bivouac until 2 o’clock waiting for rations. After getting our rations we crossed the Tennessee river by pontoon bridges and started on our way for Rome, Georgia. The railroad bridge of the Memphis & Ohio, here at Decatur, was destroyed by our gunboats soon after the battle of Shiloh. It took seventy-two pontoon boats to make our bridge. Our road today lay through a large swamp which it took some time for the artillery and provision trains to cross; besides we had some very rough country to cross, and did not get into bivouac until midnight.
