It is in the info if you read carefully. Resists capitulating: Sitting Bull 10/10,Its interesting to know which civilizations are easier to get to capitulate. The only time I've ever gotten Sitting Bull to be willing to capitulate I was besieging his last city, and just a little bit ago I was able to get Catherine to capitulate after I just wiped out one of her stacks and captured two lightly defended cities.
