Siege of Caen (1417)

The Siege of Caen took place during the Hundred Years War when English forces under Henry V laid siege to and captured Caen in Normandy from its French defenders.

Following his victory at Agincourt in 1415, Henry had returned to England and led a second invasion force across the English Channel. Caen was a large city in the Duchy of Normandy, a historic English territory. Following a large-scale bombardment Henry's initial assault was repulsed, but his brother Thomas, Duke of Clarence was able to force a breach and overrun the city. The castle held out until 20 September before surrendering.

Caen remained in English hands until 1450 when it was taken back during the French reconquest of Normandy in the closing stages of the war.
