 Johnston instructed Beauregard to stay in the rear and direct men and supplies as needed, while he rode to the front to lead the men on the battle line.This effectively ceded control of the battle to Beauregard, who had a different concept, which was simply to attack in three waves and push the Union army eastward to the river.The corps of Hardee and Bragg began the assault with their divisions in one line, nearly wide and about from its front to its rear column.
