Juan de Oñate encountered the Escanjaque in 1601 during an expedition to the Great Plains of Texas, Oklahoma, and Kansas.
A Mexican Indian named Jusepe Gutierrez, from Culiacan, Mexico, guided Oñate.
However, when Oñate returned to the Escanjaque settlement the next day, the Indians had turned unfriendly and he estimated that 1,500 men attacked him.
Oñate said that several Spaniards were wounded in the battle and claimed that a large number of Indians were killed.
One of those kidnapped was named Miguel, a captive of the Escanjaques himself from a land he called Tancoa, possibly the Tonkawa of North Texas and Oklahoma.
His information enabled the Spanish to draw a map of the region in which the Aguacane seemed to be located in southwestern Oklahoma along the Red River and its tributaries.
[8] Given their geographic location, the Aguacane might also be identical or related to the people called Teyas by Francisco Vásquez de Coronado 60 years before Oñate.
[10] The site of the Escanjaque settlement has not been found and the geographical details in Oñate's account of his journey do not permit a location to be determined with certainty.
Extrapolating backwards a location near Tonkawa for the Escanjaque settlement fits with Oñate's account.
