The French played a vital role in the American colonists' victory during the Revolutionary War, particularly at the Battle of Yorktown in 1781. They provided critical military support, including troops, naval forces, and artillery, which helped to besiege British General Cornwallis. The French navy's blockade prevented British reinforcements from reaching Yorktown, effectively sealing the fate of British forces. This collaboration significantly contributed to the ultimate defeat of the British and the success of the American Revolution.
