I think Hood had a mental lapse late in the war. To much morphine? His unbridled butchery really got going when he took over the Army of Tennessee.
Hood was tough as nails. Lose a leg and arm but still on horseback leading troops? Holy crap.
Of course, it reminds me of that old joke about the man visiting a farm who sees a pig in the pen hobbling around on three legs. When the visitor asks the farmer about the pig, the farmer says “Well, he’s a special ‘un. My farmhouse caught on fire last year, and he saved me and my family by waking us up. Yeah, he’s special.” So the visitor said “Wow! Did he lose his leg in the fire?”
The farmer said “Oh, no. A pig that good, you just can’t eat all at once!”
(No disrespect intended to Gen. Hood...it was just what came to mind!)
It could be his injuries. It could be morphine. It could be the fact that some men rise above their abilities. While Hood was fantastic as a division and brigade commander, and excellent as a corps commander, he was a bloody disaster as an army commander.
