 In his book "Los Comanches", historian Stanley Noyes notes that a "violation of a council represented an almost unthinkable degree of perfidy.The council was sacred not only to the [Comanche] People but to all Native Americans".In response, the captives the Texians sought were killed and Buffalo Hump launched the Great Raid of 1840, leading hundreds of Comanche warriors on raids against many Texian villages.
