What was the last major battle of the American Revolutionary War?

The Battle of Yorktown is recognized as the last major battle of the American Revolutionary War, taking place in 1781. This decisive encounter featured American and French forces led by General George Washington and the Comte de Rochambeau against British troops commanded by General Cornwallis. The successful siege at Yorktown effectively trapped the British army, leading to Cornwallis's surrender, which significantly weakened British resolve to continue the conflict. The outcome helped pave the way for peace negotiations, ultimately resulting in the Treaty of Paris in 1783, which formally acknowledged American independence. The significance of Yorktown in marking the conclusion of major military operations during the revolution defines its status as the final major battle of the war.
