Johnston wanted to give command of Fort Donelson to Beauregard, who had performed ably at Bull Run, but the latter declined because of a throat ailment. Instead, the responsibility went to Brig. Gen. John B. Floyd, who had just arrived following an unsuccessful assignment under Robert E. Lee in western Virginia. Floyd was a wanted man in the North for alleged graft and secessionist activities when he was Secretary of War in the James Buchanan administration. Floyd's background was political, not military, but he was nevertheless the senior brigadier general on the Cumberland River.
