The Battle of Saumur occurred during the last stages of the Battle of France during World War II, when officer cadets from the Cavalry School at Saumur, led by superintendent Colonel Charles Michon, made a defensive stand along the Loire River at Saumur, Gennes, and Montsoreau. For two days the Cavalry School, and other assorted units which had fallen back before the German Wehrmacht advance, held off a German attack. Since the battle occurred after the message by Marshal Pétain which called for an end to fighting (on 17 June 1940), the event is often considered one of the first acts of the French Resistance.
