More than half of Braddock’s men were killed or wounded by the French ambush at Fort Duquesne. Option B is correct.
The Braddock expedition was a failed British military expedition which sought to capture the French Fort Duquesne in the summer of 1755 during the French and Indian War. It was defeated at the Battle of the Monongahela on July 9, and the survivors retreated. The expedition received its name from General Edward Braddock, who led the British forces and died in the effort. Braddock's defeat was a major setback for the British in the early stages of the war with France and was considered one of the most disastrous defeats for the British in the 18th century.
