They were giants, and had a "considerable habitation." When the Great Spirit made the people, some of them became giants. After a time, and having endured the outrages of these giants, it is said that the people banded together, and through the final force of about 800 warriors, successfully annihilated the abhorrent Ronnongwetowanca. After that, it was said that there were no giants anywhere. This was supposed to have happened around 2,500 winters before Columbus discovered America, around 1000 BC.
