In 1152, Guillaume IV de Montsoreau sided with Geoffroy Plantagenet against his brother Henry II Plantagenet, future king of England and husband of Eleanor of Aquitaine. Henri II besieged the castle and took it at the end of August 1152 despite the care taken at its fortification. This was the one and only storming of the medieval fortress of Montsoreau between Fulk and Jean II de Chambes in 1450.
