Early this morning, at 6 o'clock, we moved up the river and entering the Yazoo river we reached Haines's Bluff, where we landed and stacked arms. Here we remained several hours awaiting orders. General Sherman has just taken Haines's Bluff and now is uniting with General Grant's forces in surrounding Vicksburg. At 4 o'clock we again took boat, returning down the river to Young's Point, where we landed, and marching across the point again took the boats. We passed on down the river below Vicksburg to Warrington, Mississippi, where we landed, and marching out about five miles, went into camp for the night.
