American Revolutionary War: The Royal Navy defeats the Penobscot Expedition with the most significant loss of United States naval forces prior to the attack on Pearl Harbor.

The American Revolutionary War, also known as the Revolutionary War or American War of Independence or simply the American Revolution, 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 1783, in the Treaty of Paris, the British Crown acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.
