Braddock led about 2,000 army troops and provincial militia on an expedition in June 1755 to take Fort Duquesne. The expedition ended in disaster, with Braddock mortally wounded. Two future opponents in the American Revolutionary War, Washington and Thomas Gage, played key roles in organizing the retreat. One consequence of the debacle was that the French acquired a copy of the British war plans, including the activities of Shirley and Johnson. Shirley's efforts to fortify Oswego bogged down in logistical difficulties magnified by Shirley's inexperience in managing large expeditions. When it was clear he would not have time to mount an expedition across Lake Ontario to Fort Ontario, Shirley left garrisons at Oswego, Fort Bull, and Fort Williams (the latter two located on the Oneida Carry between the Mohawk River and Wood Creek at present-day Rome, New York). Supplies for use in the projected attack on Niagara were cached at Fort Bull.
