Final answer:
General Edward Braddock was sent to capture Fort Duquesne, but his force was ambushed and defeated by the French and their Native American allies.
Step-by-step explanation:
In 1755, the British dispatched General Edward Braddock to capture Fort Duquesne.
Braddock led his force 125 miles from Fort Cumberland, Maryland, to within six miles of Fort Duquesne. However, the French and their Native American allies ambushed the British force, causing panic and defeating them.Earlier, in 1754, George Washington was involved in the region, notably at the Battle of Jumonville Glen and the later surrender of Fort Necessity. However, it was General Braddock who led the major expedition to take Fort Duquesne from the French. The effort to seize the fort marked a critical moment in the early stages of the French and Indian War and impacted British military strategy moving forward.
This campaign of 1755 proved to be a disaster for the British, with many casualties including General Braddock.
