Career
At the time he was serving under the English King Edward II. Born c. 1280 at or near Argentan, d'Argentan had participated in a Crusade to the Middle East via the Knights of Rhodes, during which he had been captured by the Emperor of Byzantium. Edward had ransomed d'Argentan from that Emperor, so as to place a well-respected warrior at his side.
On 24 June 1314, the second day of the Battle of Bannockburn, d'Argentan was riding with the Earl of Pembroke on either side of King Edward. When it became clear that the battle was lost, the knight and the Earl drew the King to safety, in spite of his protests, and in spite of the worsening confusion among the English ranks. After coming clear of the melée, d'Argentan told the King that he had never fled from a battle "nor will I now." He turned back to face the Scots, and was killed.
