I think I first heard this on a Win Stracke LP of Civil War songs made in the early 60s - seemingly part of the activities related to the centenary of the Civil War.

It is an obvious reference to the contrast between Joseph E Johnston's careful campaigning, preserving the lives of hs troops, and John B Hood's more attacking style, which culminated in the defeats of Franklin and Nashville, in which Hood's army became the only one in the whole war to be totally destroyed as a fighting force.
