American Revolution *The Surrender of Lord Cornwallis* (at Yorktown, Virginia, on October 19, 1781), oil on canvas by John Trumbull, completed in 1820; in the U.S. Capitol Rotunda, Washington, D.C. The painting captures the moment when major fighting during the American Revolution ended and the colonies achieved independence.

French military and financial support was a decisive factor in the American victory during the American Revolution. Although France initially maintained neutrality, it secretly provided the colonies with essential munitions and loans starting in 1776. Following the American victory at the Battle of Saratoga, the two nations formalized their partnership with the Franco-American Alliance in 1778, which officially recognized the United States and committed France to the war effort.1

This support was multifaceted:

Financial and Material Aid: France provided critical loans and supplies that sustained the Continental Army throughout the conflict.1
Military Personnel: French aristocrats like the Marquis de Lafayette served as officers, while the comte de Rochambeau led 6,000 infantry to fight alongside American forces.2
Naval Power: The French fleet challenged British control of North American waters. The Battle of the Chesapeake was particularly vital, as it prevented British naval relief for Lord Cornwallis, directly enabling the successful Siege of Yorktown and the ultimate British surrender.13
