Battle of Morlaix in the Hundred Years' War

The battle of Morlaix was fought near the village of Lanmeur in Brittany on 30 September 1342 between an Anglo-Breton army and a far larger Franco-Breton force. England, at war with France since 1337 in the Hundred Years' War, had sided with John of Montfort's faction in the Breton Civil War shortly after it broke out in 1341. The French were supporting Charles of Blois, a nephew of the French king.

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.

September 30 is the 273rd day of the year in the Gregorian calendar; 92 days remain until the end of the year.
