The sense of injury produced on the minds of the French by the treachery of these adventurers stirred the authorities up to attack the posts in Hudson Bay. Governor Denonville now came heartily to the aid of the Northern Company, and commissioned Chevalier de Troyes to organize an overland expedition from Quebec to Hudson Bay. The love of adventure was strong in the breasts of the young French _noblesse_ in Canada. Four brothers of the family Le Moyne had become known for their deeds of valour along the English frontier. Leader among the valorous French-Canadians was Le Moyne D'Iberville, who, though but twenty-four years of age, had already performed prodigies of daring. Maricourt, his brother, was another fiery spirit, who was known to the Iroquois by a name signifying "the little bird which is always in motion." Another leader was Ste. Helene. With a party of chosen men these intrepid spirits left the St. Lawrence in March, 1685, and threaded the streams of the Laurentian range to the shore of Hudson Bay. [Illustration: LE MOYNE D'IBERVILLE.] After nearly three months of the most dangerous and exciting adventures, the party reached their destination. The officers and men of the Hudson's Bay Company's service were chiefly civilians unaccustomed to war, and were greatly surprised by the sudden appearance upon the Bay of their doughty antagonists. At the mouth of the Moose River one of the Hudson's Bay Company forts was situated, and here the first attack was made. It was a fort of considerable importance, having four bastions, and was manned by fourteen guns. It, however, fell before the fierce assault of the forest rangers. The chief offence in the eyes of the French was Charles Fort on the Rupert River, that being the first constructed by the English Company. This was also captured and its fortifications thrown down. At the same time that the main body were attacking Charles Fort, the brothers Le Moyne, with a handful of picked men, stealthily approached in two canoes one of the Company's vessels in the Bay and succeeded in taking it. The largest fort on the Bay was that in the marshy region on Albany River. It was substantially built with four bastions and was provided with forty-three guns. The rapidity of movement and military skill of the French expedition completely paralyzed the Hudson's Bay Company officials and men. Governor Sargeant, though having in Albany Fort furs to the value of 50,000 crowns, after a slight resistance surrendered without the honours of war. The Hudson's Bay Company employés were given permission to return to England and in the meantime the Governor and his attendants were taken to Charlton Island and the rest of the prisoners to Moose Fort. D'Iberville afterwards took the prisoners to France, whence they came back to England.
