Three days after the council, the Iroquois set out on their return; and, as the palisades of the fort were now finished, and the barracks nearly so, Frontenac began to send his party homeward by detachments. He himself was detained, for a time, by the arrival of another band of Iroquois, from the villages on the north side of Lake Ontario. He repeated to them the speech he had made to the others; and, this final meeting over, embarked with his guard, leaving a sufficient number to hold the fort, which was to be provisioned for a year by means of a convoy, then on its way up the river. Passing the rapids safely, he reached Montreal on the first of August. His enterprise had been a complete success. He had gained every point, and, in spite of the dangerous navigation, had not lost a single canoe. Thanks to the enforced and gratuitous assistance of the inhabitants, the whole had cost the king only about ten thousand francs, which Frontenac had advanced on his own credit. Though, in a commercial point of view, the new establishment was of very questionable benefit to the colony at large, the Governor had, nevertheless, conferred an inestimable blessing on all Canada, by the assurance he had gained of a long respite from the fearful scourge of Iroquois hostility. "Assuredly," he writes, "I may boast of having impressed them at once with respect, fear, and good-will." [Footnote: _Lettre de Frontenac au Ministre_, 13 Nov. 1673.] He adds, that the fort at Cataraqui, with the aid of a vessel, now building, will command Lake Ontario, keep the peace with the Iroquois, and cut off the trade with the English. And he proceeds to say, that, by another fort at the mouth of the Niagara, and another vessel on Lake Erie, we, the French, can command all the upper lakes. This plan was an essential link in the scheme of La Salle; and we shall soon find him employed in executing it.
