Reputed to be ‘the third best knight in Europe’, d’Argentan was an experienced and formidable fighter. He was famous for winning many jousts and had also been on crusade into the eastern Mediterranean.
Edward valued him greatly and had gone to some trouble to ensure his release after he had been captured whilst on crusade. The English king had arranged for his release specifically so he could accompany him on the march to Bannockburn.
In battle, d’Argentan had the task of personally protecting Edward and stayed by his side throughout the battle. Once it was obvious that all was lost for the English, d’Argentan and Pembroke urged Edward to leave the battlefield. They escorted the king to safety, fighting their way through the Scots. His duty done, d’Argentan turned around and charged back into the battle, where he was killed.
His death, one of the highest-profile casualties on the English side, was a source of sadness but also admiration for both English and Scottish writers after the battle.
