One of the major chieftains living on the Illinois River, Comas is first recorded as head of the Indian village of Wappa on Bureau Creek.
The village was one of the largest Potawatomi settlements in the region and located eight miles from the river on present-day Tiskilwa, Illinois.
[1] In 1809, he was one of several chieftains visited by Joseph Trotier who brought "assurances of peace and friendship" from Governor Ninian Edwards.
As a token of friendship, Comas presented Trotier with a pair of large elk horns and a panther skin, which he had fashioned himself, as a gift for Governor Edwards.
[4][5][6] He later took part in the Peoria War, his village being the staging point for Black Partridge's raid against Fort Clark in the fall of 1813,[7] and was one of thirteen chieftains sent to St. Louis, Missouri to negotiate peace.
