Here is an excerpt from Iseeo’s account. Iseeo was a member of a war party returning from a raid against the Utes, when they encountered a tornado near the Washita River in Oklahoma.
Suddenly, the leader of the party shouted for the men to dismount and prepare for a hard rain. Soon, too, with the approaching cloud, lseeo recalled hearing a -roar that sounded like buffalo in the rutting season. Sloping down from the cloud a sleeve appeared, its center red; from this lightning shot out. The tremendous funnel tore through the timber bordering the Washita. heaving trees into the air.
Some of the young men wanted to run away, but the older, more experienced Kiowas knew what must be done. They called for everyone to try hard and brace themselves. The elders drew their pipes from saddlebags and lit them. They raised their pipes to the storm spirit, entreating it to smoke, and to go around them. The cloud heard their prayers, lseeo explained, and passed by.
This group, at least, tried to make peace with Mánkayía so that they could escape unharmed.
