On the morning of March 15, 1783, General George Washington makes a surprise appearance at an assembly of army officers at Newburgh, New York, to calm the growing frustration and distrust they had been openly expressing towards Congress in the previous few weeks. Angry with Congress for failing to honor its promise to pay them and for its failure to settle accounts for repayment of food and clothing, officers began circulating an anonymous letter condemning Congress and calling for a revolt.

On May 18, 1783, the first United Empire Loyalists, known to American Patriots as Tories, arrive in Canada to take refuge under the British crown in Parrtown, Saint John, Nova Scotia (now New Brunswick), Canada. The town was located on the Bay of Fundy just north of the border with what is now the state of Maine.

Hearing arguments in the case of the Zong, a slave ship, the Chief Justice of the King’s Bench in London states that a massacre of enslaved African “was the same as if Horses had been thrown over board” on May 22, 1783. The crew of the Zong had thrown at least 130 captive Africans into the sea, but the question before the court was not who had committed this atrocity but rather whether the lost “cargo” was covered by insurance. The trial laid bare the horror and inhumanity of the Atlantic slave trade and galvanized the nascent movement to abolish it.

The American Revolution officially comes to an end when representatives of the United States, Great Britain, Spain and France sign the Treaty of Paris on September 3, 1783. The signing signified America’s status as a free nation, as Britain formally recognized the independence of its 13 former American colonies, and the boundaries of the new republic were agreed upon: Florida north to the Great Lakes and the Atlantic coast west to the Mississippi River.

On November 15, 1783, John Hanson, the first president of the Continental Congress under the Articles of Confederation, dies in his home state of Maryland. Hanson is sometimes called the first president of the United States, but this is a misnomer, since the presidency did not exist as an executive position separate from Congress until the federal Constitution created the role upon its ratification in 1789.

French physician Jean-François Pilatre de Rozier and François Laurent, the marquis d’ Arlandes, make the first untethered hot-air balloon flight, flying 5.5 miles over Paris in about 25 minutes. Their cloth balloon was crafted by French paper-making brothers Jacques-Étienne and Joseph-Michel Montgolfier, inventors of the world’s first successful hot-air balloons.

On November 25, 1783, nearly three months after the Treaty of Paris was signed ending the American Revolution, the last British soldiers withdraw from New York City, the last British military position in the former Thirteen Colonies. After the last Redcoat departed New York, U.S. General George Washington entered the city in triumph to the cheers of New Yorkers. The city had remained in British hands since its capture in September 1776.

On December 4, 1783, future President George Washington, then commanding general of the Continental Army, summons his military officers to Fraunces Tavern in New York City to inform them that he will be resigning his commission and returning to civilian life.

On December 23, 1783, following the signing of the Treaty of Paris, General George Washington resigns as commander in chief of the Continental Army and retires to his home at Mount Vernon, Virginia.
