Hardly a ringing endorsement. Davis thought that Braxton Bragg was an fine general, too.
Albert Johnston was much like Lee and had he survived to command the western armies the Union armies in the west would have had a much harder fight.

Albert Johnston had proven his command ability in his previous roles with the Texas Republic and the US Army.
