French and Indian War and afterwards
George Washington was commissioned in 1754 as a colonel in the Virginia Militia and built a series of forts in the western frontier of Virginia. He was dispatched by the governor of Virginia, Robert Dinwiddie, to force the French out of the Ohio valley. When they refused, he attacked a French scouting party, killing ten, including its leader, Jumonville. Anticipating retaliation, he built a small fort (Fort Necessity). It proved ineffective: Washington's forces were vastly outnumbered and the fort, built on low ground, flooded during a heavy rainfall. He was forced to surrender and negotiated a safe passage back to Virginia. Nevertheless, the incident ignited the French and Indian War.
Washington next accompanied the Braddock Expedition of the British Army during the French and Indian War. During the Battle of the Wilderness near the Monongahela River, he had three horses shot out from under him, and four bullets pierced his coat. He showed his coolness under fire in organizing the retreat from the debacle. Washington then organized the First Virginia Regiment, which saw service through the war.
In 1757, he resigned his commission and married Martha Dandridge Custis, the wealthy widow of Daniel Parke Custis. Washington adopted Custis's two children and never fathered any of his own. The newlywed couple moved to Mount Vernon where he took up the life of a genteel farmer. He became a member of the House of Burgesses.
By 1774, Washington had become one of the colonies' wealthiest men. In that year, he was chosen as a delegate from Virginia to the First Continental Congress and the next year to the Second Continental Congress. He did not support colonial independence until 1776, when he read Thomas Paine's Common Sense.
