In 1346, King Edward III of England led his army against the city, hoping to loot it. It was expected that a siege of perhaps several weeks would be required, but the army took the city in less than a day, on 26 July 1346, storming and sacking it, killing 3,000 of its citizens, and burning much of the merchants' quarter on the Ile Ste-Jean. Only the castle of Caen held out, despite attempts to besiege it. A few days later, the English left, marching to the east and on to their victory at the Battle of Crécy. It was later captured following a siege by Henry V in 1417 and treated harshly for being the first town to put up any resistance to his invasion. In 1450 towards the end of the war, French forces recaptured Caen.
