The English were about to suffer still other reverses. In 1691 Major Schuyler, with a small army composed in part of savages, came and surprised below the fort of the Prairie de la Madeleine a camp of between seven and eight hundred soldiers, whose leader, M. de Saint-Cirque, was slain; but the French, recovering, forced the major to retreat, and M. de Valrennes, who hastened up from Chambly with a body of inhabitants and Indians, put the enemy to flight after a fierce struggle. The English failed also in Newfoundland; they were unable to carry Fort Plaisance, which was defended by M. de Brouillan; but he who was to do them most harm was the famous Pierre Le Moyne d'Iberville, son of Charles Le Moyne. Born in Montreal in 1661, he subsequently entered the French navy. In the year 1696 he was ordered to drive the enemy out of Newfoundland; he seized the capital, St. John's, which he burned, and, marvellous to relate, with only a hundred and twenty-five men he subdued the whole island, slew nearly two hundred of the English, and took six or seven hundred prisoners. The following year he set out with five ships to take possession of Hudson Bay. One day his vessel found itself alone before Fort Nelson, facing three large ships of the enemy; to the amazement of the English, instead of surrendering, d'Iberville rushes upon them. In a fierce fight lasting four hours, he sinks the strongest, compels the second to surrender, while the third flees under full sail. Fort Bourbon surrendered almost at once, and Hudson Bay was captured. After the peace d'Iberville explored the mouths of the Mississippi, erected several forts, founded the city of Mobile, and became the first governor of Louisiana. When the war began again, the king gave him a fleet of sixteen vessels to oppose the English in the Indies. He died of an attack of fever in 1706. During this time, the Iroquois were as dangerous to the French by their inroads and devastations as the Abenaquis were to the English colonies; accordingly Frontenac wished to subdue them. In the summer of 1696, braving the fatigue and privations so hard to bear for a man of his age, Frontenac set out from Ile Perrot with more than two thousand men, and landed at the mouth of the Oswego River. He found at Onondaga only the smoking remains of the village to which the savages had themselves set fire, and the corpses of two Frenchmen who had died in torture. He marched next against the Oneidas; all had fled at his approach, and he had to be satisfied with laying waste their country. There remained three of the Five Nations to punish, but winter was coming on and Frontenac did not wish to proceed further into the midst of invisible enemies, so he returned to Quebec.
