The name of the French general who assisted Washington was Rochambeau.

The French general who assisted George Washington during the Revolutionary War was Jean-Baptiste Donatien de Vimeur, comte de Rochambeau. Arriving in America in 1780, Rochambeau brought essential troops and resources that bolstered the Continental Army. His collaboration with Washington was crucial in coordinating military strategies, particularly during the decisive Siege of Yorktown in 1781. Rochambeau's leadership and tactical expertise helped encircle British General Cornwallis, ultimately leading to the British surrender. This victory was a turning point in the war, and Rochambeau’s contributions significantly strengthened the alliance between France and the United States, playing a vital role in achieving American independence.
