On Sunday, the 28th, Col. James H. Coates, commanding the expedition, disembarked his cavalry, the 1st Miss. colored, 6 miles from Yazoo City and ordered it to reconnoiter in the rear of the city. Before long the pickets were attacked and Maj. Cook with a detachment of the cavalry started out and after some skirmishing came on Ross' entire command. About 3 p.m. he returned, closely pursed by a superior force of Confederates, who were only repulsed after the infantry had been advanced to meet them. The casualties were not reported.
