The Braddock expedition

(Wikipedia) - The Braddock expedition (also called "Braddock's campaign") was a failed British attempt to capture the French Fort Duquesne in the summer of 1755 during the French and Indian War. The expedition takes its name from General Edward Braddock, who led the British forces and died in the effort. Braddock's defeat at the Battle of the Monongahela was a major setback for the British in the early stages of the war with France.

Setting out from Fort Cumberland in Maryland on May 29, 1755, the expedition faced an enormous logistical challenge: moving a large body of men with equipment, provisions, and (most importantly for the task ahead) heavy cannon, across the densely wooded Allegheny Mountains and into western Pennsylvania, a journey of about 110 miles. Braddock had received important assistance from Benjamin Franklin, who helped procure wagons and supplies for the expedition. Among the wagoners, incidentally, were two young men who would later become legends of American history: Daniel Boone, and Daniel Morgan. Other members of the expedition were Ensign William Crawford (soldier) and Charles Scott (governor of Kentucky). Among the British were Thomas Gage; Charles Lee and Horatio Gates. Continued
