Bradstreet was an officer of spirit. Pushing his way along the valley of the Mohawk and by the Oneida, where he was joined by several warriors of the Six Nations, he arrived at Oswego in August, with nearly three thousand men; the greater part of them provincial troops of New York and Massachusetts. Embarking at Oswego in open boats, he crossed Lake Ontario, and landed within a mile of Frontenac. The fort mounted sixty guns, and several mortars, yet though a place of such importance, the garrison consisted of merely one hundred and ten men, and a few Indians. These either fled, or surrendered at discretion. In the fort was an immense amount of merchandise and military stores; part of the latter intended for the supply of Fort Duquesne. In the harbor were nine armed vessels, some of them carrying eighteen guns; the whole of the enemy's shipping on the lake. Two of these Colonel Bradstreet freighted with part of the spoils of the fort, the others he destroyed; then having dismantled the fortifications, and laid waste every thing which he could not carry away, he recrossed the lake to Oswego, and returned with his troops to the army on Lake George.

Operations went on slowly in that part of the year's campaign in which Washington was immediately engaged--the expedition against Fort Duquesne. Brigadier-general Forbes, who was commander-in-chief, was detained at Philadelphia by those delays and cross-purposes incident to military affairs in a new country. Colonel Bouquet, who was to command the advanced division, took his station, with a corps of regulars, at Raystown, in the centre of Pennsylvania. There slowly assembled troops from various parts. Three thousand Pennsylvanians, twelve hundred and fifty South Carolinians, and a few hundred men from elsewhere. Washington, in the mean time, gathered together his scattered regiment at Winchester, some from a distance of two hundred miles, and diligently disciplined his recruits. He had two Virginia regiments under him, amounting, when complete, to about nineteen hundred men. Seven hundred Indian warriors, also, came lagging into his camp, lured by the prospect of a successful campaign.
