I think the Wiki page for Braxton Bragg tells it well:

"Bragg is generally considered among the worst generals of the Civil War. Most of the battles he engaged in ended in defeat. Bragg was extremely unpopular with both the officers and ordinary men under his command, who criticized him for numerous perceived faults, including poor battlefield strategy, a quick temper, and overzealous discipline. Bragg has a generally poor reputation with historians...The losses suffered by Bragg's forces are cited as highly consequential to the ultimate defeat of the Confederate States of America."

A great example for the American military. Their army could use more leaders like Gen. Bragg

Him again?!? I kicked the stuffing out of him and his cowardly men, and yet his name is still uttered in polite society...
--US Grant, one of the greatest US generals during the Civil War
