A great danger menaced the colony in the year 1621. The Iroquois sent three large parties of warriors to attack the French settlements. This savage tribe feared that if the white men obtained a footing in the country, their alliance with the Hurons and Algonquins, of which the effects had already been felt, might render them too powerful. The first division marched upon Sault St. Louis, where a few Frenchmen were established. Happily, there was warning of their approach; the defenders, aided by some Indian allies, repulsed them with much loss, and took several prisoners. The Iroquois had, however, seized Father Guillaume Poulain, one of the Recollets, in their retreat; they tied him to a stake, and were about to burn him alive, when they were persuaded to exchange the good priest for one of their own chiefs, who had fallen into the hands of the French. Another party of these fierce marauders dropped down the river to Quebec in a fleet of thirty canoes, and suddenly invested the Convent of the Recollets, where a small fort had been erected; they did not venture to attack this little stronghold, but fell upon some Huron villages near at hand, and massacred the helpless inhabitants with frightful cruelty; they then retreated as suddenly as they had come. Alarmed by this ferocious attack, which weakness and the want of sufficient supplies prevented him from avenging, Champlain sent Father Georges le Brebeuf as an agent, to represent to the king the deplorable condition of the colony, from the criminal neglect of the company. The appeal was successful; the company was suppressed, and the exclusive privilege transferred to Guillaume and Emeric de Caen, uncle and nephew. The king himself wrote to his worthy subject Champlain, expressing high approval of his eminent services, and exhorting him to continue in the same career. This high commendation served much to strengthen his hands in the exercise of his difficult authority. He was embarrassed by constant disputes between the servants of the suppressed company, and those who acted for the De Caens; religious differences also served to embitter these dissensions, as the new authorities were zealous Huguenots. This year Champlain discovered that his ancient allies, the Hurons, purposed to detach themselves from his friendship, and unite with the Iroquois for his destruction. To avert this danger, he sent among them Father Joseph la Caron and two other priests, who appear to have succeeded in their mission of reconciliation. The year after, he erected a stone fort[108] at Quebec for the defense of the settlement, which then only numbered fifty souls of all ages and sexes. As soon as the defenses were finished, Champlain departed for France with his family, to press for aid from the government for the distressed colony.
