Radisson was first captured by the Iroquois, and adopted into one of their tribes. After two years he escaped, and having been taken to Europe, returned to Montreal. Shortly afterwards he took part in the wars between the Hurons and Iroquois. Chouart was for a time assistant in a Jesuit mission, but, like most young men of the time, yielded to the attractions of the fur trade. He had married first the daughter of Abraham Martin, the French settler, after whom the plains of Abraham at Quebec are named. On her death Chouart married the widowed sister of Radisson, and henceforth the fortunes of the two adventurers were closely bound up together. The marriage of Chouart brought him a certain amount of property, he purchased land out of the proceeds of his ventures, and assumed the title of Seignior, being known as "Sieur des Groseilliers." In the year 1658 Groseilliers and Radisson went on the third expedition to the west, and returned after an absence of two years, having wintered at Lake Nepigon, which they called "Assiniboines." It is worthy of note that Radisson frankly states in the account of his third voyage that they had not been in the Bay of the North (Hudson Bay). The fourth voyage of the two partners in 1661 was one of an eventful kind, and led to very important results. They had applied to the Governor for permission to trade in the interior, but this was refused, except on very severe conditions. Having had great success on their previous voyage, and with the spirit of adventure inflamed within them, the partners determined to throw off all authority, and at midnight departed without the Governor's leave, for the far west. During an absence of two years the adventurers turned their canoes northward, and explored the north shore of Lake Superior. It is in connection with this fourth voyage (1661) that the question has been raised as to whether Radisson and his brother-in-law Groseilliers visited Hudson Bay by land. The conflicting claim to the territory about Hudson Bay by France and England gives interest to this question. Two French writers assert that the two explorers had visited Hudson Bay by land. These are, the one, M. Bacqueville de la Potherie, Paris; and the other, M. Jeremie, Governor of the French ports in Hudson Bay. Though both maintain that Hudson Bay was visited by the two Frenchmen, Radisson and Groseilliers, yet they differ entirely in details, Jeremie stating that they captured some Englishmen there, a plain impossibility. Oldmixon, an English writer, in 1708, makes the following statement:--"Monsieur Radisson and Monsieur Gooselier, meeting with some savages in the Lake of the Assinipouals, in Canada, they learnt of them that they might go by land to the bottom of the bay, where the English had not yet been. Upon which they desired them to conduct them thither, and the savages accordingly did it." Oldmixon is, however, inaccurate in some other particulars, and probably had little authority for this statement.
