In 1611, in the early spring, Champlain started from Quebec in order to meet the Indians with the young Frenchman, and give back the hostages left at the settlement; but not finding them, he continued to explore the country as far as Mont Royal, or Montreal. Shortly after the natives arrived, and after exchanging presents, he took leave of them, trusting another lad to their care, with particular instructions as to the observations he was to make while with them. He returned to Quebec in June, and finding matters proceeding regularly he sailed for France, arriving at La Rochelle on the 11th of August. On the 5th of March of the next year (1612), Champlain again embarked at Honfleur for Quebec, arriving on the 7th of May, and finding all who had wintered there in health and prospering. The winter had been so mild that the river had not been frozen, "the trees also began to reclothe themselves with leaves, and the fields to be enameled with flowers." On the 23rd, he left Quebec for the Sault St. Louis with two canoes, having with him only four men, one of whom was a certain Nicolas Vignan, "the most impudent liar that had been seen for a long time," as will presently appear. One of Champlain's cherished projects was to endeavour to penetrate to the Arctic Sea by means of some of the rivers tributary to the St. Lawrence, which, by the account of the natives, had their sources in great lakes, from which other streams flowed towards the north. This man Vignan had formerly wintered with the natives, and had been sent on journeys of exploration by Champlain on various occasions. He had returned to Paris, where, in the commencement of the present year (1612), he had assured Champlain that he had seen the Northern Sea; that the Algenquin river issued from a lake, which by another river discharged itself into the said sea, and that in seventeen days he might go to it from Sault St. Louis. He added that he had seen the wreck of an English ship which had been lost on the coast, and that eighty men had escaped to land, where they had all been killed by the savages. He had been shown their heads, which had been skinned (scalped) according to their custom; and the Indians wished to present them to Champlain, with a young English boy whom they had preserved.
