That is creative. It reminds me of the Apache torture methods. They captured a family in a wagon in southwest New Mexico and tied the father to the wheel right side up. .They built a fire and then rolled his head into the fire. Savages.
I don’t know how true it is but in some realistic westerns I’ve seen them torture a cowboy or army guy by tying him down then building a fire under his feet and moving the fire up his leg as it burns away. The pain must have been ‘almost’ unbearable but not enough to kill them; at least not quickly. If they were lucky the damage and pain would cause them to pass out for a time.
The savagery of such an act boggles the mind. It’s clear they didn’t think of their enemy as human. I like to think some of them got the same treatment at some point down the line.
Of course from their perspective the white man had probably killed someone close to them so the hate in their hearts and minds must have been raging out of control. In such a state; I’m not so sure I wouldn’t want to do something equally savage if I had seen the enemy kill my wife and kids or parents.
