When Abercromby was fully secured in his old position, and discipline in a measure re-established in the army, he hearkened to the earnest solicitations of the indefatigable Bradstreet, that a force might be sent to revenge on Fort Frontenac the ruin of Oswego, and thus to gain the command of Lake Ontario. The carrying out of this plan was worthily committed to him who had designed it, and a detachment of Artillery, and two companies of regulars, with 2800 Provincial militia and boatmen, were allotted for the task. The pusillanimous destruction of the navigation of Wood Creek by General Webb in 1756 proved a most vexatious and harassing difficulty in this expedition. But the resolution and energy of Bradstreet overcame every obstacle; with immense labor and hardship, his men removed the logs from the river, and at length rendered it navigable. On the 13th of August the artillery and stores were embarked, and the same day the army moved by land to the Oneida Lake; thence, by the stream of the Onondaga, past the scene of their leader's brilliant victory, to the waters of Lake Ontario, where they again embarked. On the 25th, Bradstreet landed without opposition within a mile of Fort Frontenac; he found this famed position[138] weakly fortified and worse garrisoned, through the unaccountable negligence of the Marquis de Vaudreuil. After the victory at Ticonderoga, the French governor had dispatched the Chevalier de Longueuil, with immense presents, to meet the chiefs of the Iroquois at Oswego, with a view of gaining their important alliance, and of inducing them to abandon all relations with the English, by representing their cause as ruined through Abercromby's defeat. He in some measure succeeded in his mission; the Indian deputies assured him of their attachment, but said that, as all their brethren had not been consulted, they must communicate with them before giving a decisive answer. When the conference ended, the chevalier returned to Montreal by Fort Frontenac, where he stopped for a day, and informed M. de Noyan, the commandant, of the danger that threatened his position from Bradstreet's advance. Every thing was speedily done to strengthen the fort which the limited means at hand permitted; but De Noyan, well aware that without aid resistance would be vain, urged upon De Longueuil to send him re-enforcements as soon as he could reach the governor. This the chevalier neglected, and Fort Frontenac and its worthy commandant were left to their fate. When too late indeed, the Marquis de Vaudreuil dispatched M. de Plessis Fabiot, with 1500 Canadian militia, toward Lake Ontario, but by the time they reached La Chine intelligence arrived that caused the greater part of the force to return to whence they came.
