Confederate General Albert Sidney Johnston reorganizes the Army of the Mississippi into three corps
As his troops were set in motion for a massive attack on Federal forces at Pittsburg Landing on the Tennessee River, Confederate commanding general Albert Sidney Johnston reorganized his manpower into three new corps to be commanded by generals Leonidas Polk, Braxton Bragg, and William Hardee. Major General Pierre Beauregard was named as overall second in command. Within days Beauregard was commanding as Johnston was killed on the first day of the massive battle that ensued at "Bloody Shiloh." (By John Osborne)
