Champlain's first trip to North America was as an observer on a fur-trading expedition led by François Gravé Du Pont. Du Pont was a navigator and merchant who had been a ship's captain on Chauvin's expedition, and with whom Champlain established a firm lifelong friendship. He educated Champlain about navigation in North America, including the Saint Lawrence River, and in dealing with the natives there (and in Acadia after). The "Bonne-Renommée" (the "Good Fame") arrived at Tadoussac on March 15, 1603. Champlain was anxious to see for himself all of the places that Jacques Cartier had seen and described about sixty years earlier, and wanted to go even further than Cartier, if possible. Champlain created a map of the Saint Lawrence on this trip and, after his return to France on 20 September, published an account as "Des Sauvages: ou voyage de Samuel Champlain, de Brouages, faite en la France nouvelle l'an 1603" ("Concerning the Savages: or travels of Samuel Champlain of Brouages, made in New France in the year 1603"). Included in his account were meetings with Begourat, a chief of the Montagnais at Tadoussac, in which positive relationships were established between the French and the many Montagnais gathered there, with some Algonquin friends.
