ブルターニュ継承戦争
Hennebont is famed for its resistance, under Joanna of Flanders, the widow of Jean de Montfort, to the armies of Philip of Valois and Charles of Blois when besieged in 1342 during the War of the Breton Succession. A century before Joan of Arc, Jeanne dressed herself in armor and led the resistance to the besiegers. She personally led an attack on the enemy camp, setting fire to it and earned the nickname "Jeanne la Flamme" ("Joan the Fiery").
