Francois Hidalgo committed an action which might well be considered treason by the Spanish Government. He wrote three letters of the same content, all dated January 17, 1711, addressed to the Governor of Louisiana. Only one reached its destination. In mid-summer of 1713 the Governor of Louisiana, La Mothe de Cadillac, had the letter in his possession. (There is always an incident in history which incites a chain reaction in such a way that a new era begins, always resulting in the establishment of new frontiers. The Hidalgo letter was such an incident). One must surmise how such a letter could travel through nearly a thousand miles of wilderness and reach its destination. The whole new frontier of El Camino Real hinged on this accomplishment. The contents of the letter showed that Father Hidalgo had first-hand knowledge of the land of the Hasinai and the Caddos as well as the waterways of the adjoining area. He wrote that the French traders were to ascend the Mississippi to the confluence of the Red River, then ascend the Red River to the tribe of the Natchitoches Indians, thence to travel westward over the Buffalo Trail to the Hasinai Indians and there procure guides to the Hidalgo Mission. Father Hidalgo could have acquired knowledge of the Caddo area from the reports of De Leon, Teran and Father Massinetes, but he would have not had the knowledge of the waterways, which could have only been obtained from the Natchitoches Indians who may have come to the Campti from their location on the north shore of Lake Pontchartrain; information was given to Flores and Colliea and passed on to Hidalgo.
