gave the English further control of Brittany. Aftermath The battle was very violent and severe losses occurred on both sides: 800 of the Franco-Breton side and 600 on the Anglo-Breton. It was especially serious for the Breton aristocracy supporting the party of Charles de Blois. Guy II de Nesle and the hero of the Battle of the Thirty, Alain de Tinténiac, were slain. More than eighty knights of the recently formed chivalric Order of the Star also lost their lives, possibly partly because of the oath of the order never to retreat in battle.
