Reinforced by General Don Carlos Buell, whose men came off of steamers all morning long, Grant struck at the Confederates. There was hard fighting for about two hours; the Confederates then withdrew, leaving the field to the Union. Beauregard put the best face on a bad situation, telegraphing Jefferson Davis that he had fought the enemy to a draw, but the casualty lists revealed something different. Each side had slightly more than 10,000 men killed, wounded, or missing in slightly more than twenty-four hours. That was a bad casualty list for the North, but for the South, with its limited manpower supply, it was simply disastrous.
