States' rights
Casualties for the Union Army amounted to 5,824 (753 killed, 4,722 wounded, and 349 missing) of about 56,000 engaged; Bragg reported Confederate casualties of 6,667 (361 killed, 2,160 wounded, and 4,146 missing, mostly prisoners) of about 44,000. Southern losses may have been higher; Grant claimed 6,142 prisoners. When a chaplain asked General Thomas whether the dead should be sorted and buried by state, Thomas replied "Mix 'em up. I'm tired of States' rights."
