This time line is drawn largely from the work of Richard B. Morris, in particular his Encyclopedia of American History.
The British Attack in North and South. Fighting continued in both the northern and southern states. In the frontier settlements of Pennsylvania, Loyalists and Indians led by Mohawk Joseph Brant attacked American settlers. The Loyalists soon were defeated, and Americans went on to destroy many Native American villages whose residents were fighting on the side of the British.
Spain Joins the War. Spain asked Britain for Gibraltar as a reward for joining the war on the British side. When Britain refused, Spain joined with France in its war against Britain, although refusing to recognize American independence.
The British Take Charleston, South Carolina. After a brief fight, the British took Charleston, capturing 5,400 men and four American ships in the harbor. It was the worst American defeat of the war.
A Mutiny in the Continental Army. When the value of Continental currency sank to a new low, Congress had problems supplying the American army. Great shortages of food led to a short-lived mutiny among some Connecticut soldiers at Washington's camp in New Jersey.
The Treason of Benedict Arnold. American General Benedict Arnold, frustrated and ambitious, began dealing with British General Sir Henry Clinton. After he was promised the command at West Point by General Washington, Arnold told Clinton that he would give the strategic American fortification to the British. But when British Major John André, acting as messenger, was captured, Arnold fled to a British ship, revealing his involvement in the treasonous plan. André was executed as a spy, and Arnold was made a brigadier general in the British army.
Congress Creates a Department of Finance. American finances were in such dire straits that Congress saw the need for a separate department of finance. Robert Morris was appointed superintendent of finance.
The Articles of Confederation Are Ratified. With the ratification of the Articles of Confederation, under discussion since 1777, Congress assumed a new title, "The United States in Congress Assembled."
The Battle of Yorktown. French and American forces joined at Yorktown, on land and at sea, and attacked British fortifications. Key British points were soon held by the Americans and French, and British General Cornwallis soon surrendered, giving up almost 8,000 men. With this defeat, Britain lost hope of winning the war in America.
Peace Negotiations Begin in Paris. British, French, and American commissioners met in Paris to discuss peace. The United States sent Benjamin Franklin, John Adams, and John Jay. By November, the commissioners had drafted a peace treaty. Its terms called for Great Britain to recognize American independence and provide for the evacuation of all British troops. Great Britain also gave up its territory between the Mississippi River and the Allegheny Mountains, doubling the size of the new nation.
