Battle of Formigny: Toward the end of the Hundred Years' War, the French attack and nearly annihilate English forces, ending English domination in Northern France.

The Battle of Formigny, fought on 15 April 1450, took place towards the end of the Hundred Years' War between England and France. A decisive French victory that destroyed the last significant English field army in Normandy, it paved the way for the recapture of their remaining strongholds.

The Hundred Years' War was a conflict between the kingdoms of England and France and a civil war in France during the Late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides. The periodisation of the war typically charts it as taking place over 116 years. However, it was an intermittent conflict which was frequently interrupted by external factors, such as the Black Death, and several years of truces.

April 15 is the 105th day of the year in the Gregorian calendar; 260 days remain until the end of the year.
