But the most vivid event of Frontenac's life after the defence of Quebec against Phips was the great expedition which he led in person against the Onondagas. It was an exploit which resembles Denonville's attack upon the Senecas, with the added interest that Frontenac was in his seventy-seventh year when {149} he thus carried the war into the heart of the enemy's country. As a physical _tour de force_ this campaign was splendid, and it enables us, better than any other event, to appreciate the magnificent energy which Frontenac threw into the fulfilment of his task. With over two thousand men, and an equipment that included cannon and mortars, he advanced from the south shore of Lake Ontario against the chief stronghold of the Iroquois. At the portage the Indians would not permit their aged, indomitable Onontio to walk, but insisted that he should remain seated in his canoe, while they carried it from the pool below the fall to the dead water above. All the French saw of the stronghold they had come to attack was the flame which consumed it. Following the example of the Senecas, the Onondagas, when they saw that the invader was at hand, set fire to their palisade and wigwams, gathered up what property was portable, and took to the woods. Pursuit was impossible. All that could be done was to destroy the corn and proceed against the settlement of the Oneidas. After this, with its maize, had been consumed, Frontenac considered whether he should attack the Cayugas, but he decided against this {150} extension of the campaign. Unlike Denonville, he was at war with the English as well as with the Iroquois, and may have thought it imprudent to risk surprise at a point so far from his base. While it was disappointing that the Onondagas did not wait to be destroyed by the cannon which with so much effort had been brought against them, this expedition was a useful proof of strength and produced a good moral effect throughout the colony as well as among the western tribes.
