American Revolutionary War: The war's last action, the Siege of Cuddalore, is ended by a preliminary peace agreement.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war. But Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war in the Treaty of Paris two years later, in 1783, in which the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

The siege of Cuddalore was a siege attempt by British troops against a combined French and Mysorean garrison at the fortress of Cuddalore in the Second Anglo-Mysore War. The siege ended when news arrived of a preliminary peace treaty between France and Britain.
