Oh, he was not kind to the political generals on the Union side either. Catton excoriated Nathaniel Banks, Benjamin Butler, and Franz Siegel especially.
Halleck didn’t fare much better.
In defense of Bragg he was one of the few Southern generals that took seriously discipline and the care and feeding of his troops.
Yes the south had shortages but mostly the troops looked and dressed like shit because they were allowed to look like that. Under Bragg at least the troops looked good.
