Boone was a part of an British expedition in 1755 into French territory. When the column was attacked by Indians allied to the French, the British commander, General Edward Braddock was mortally wounded and many of the soldiers were killed. This was the Battle of the Monongahela where then colonel George Washington rallied the British and the Virginia militia into an organized retreat. Boone, who was supervisor of the wagon train was one of those who retreated with Washington. He returned to North Carolina and settled on a farm near his father's. In 1756 he married Rebecca Bryan.
