The Comanche were an immensely fierce, warlike tribe, and anyone who dared to cross their warpath (as the unfortunate filibusters do) could expect little in the way of mercy. However, it should be noted that this was a period in which no one group possessed a monopoly on barbarity, and Blood Meridian is true to history in presenting all parties (be it American, Mexican or Native American) as equally given to committing atrocities.
For those readers who feel McCarthy’s graphic desciption of the Comance attack verges on the sensational, it may be worth quoting historian Tom DeShields on the Indian treatment of enemies:
Though having lost one of their comrades in the fight, the Tonkawa were elated over the victory, and after scalping the dead and dying Wacos and Comanches, cutting off their hands, feet, arms and legs, and fleecing strips of flesh from their thighs and breast, they were ready and anxious to return to their village and engage in their usual cannibal-like and mystic war dance.
