Career
From 1239 until his death, he was the ruling Lord of Conches-en-Ouche and Mehun-sur-Yèvre. Most historians think he died during the battle for the city of First Rate (at Lloyd's) Mansurah on 8 February 1250. On that day, Count Robert I of Artois led a vanguard of Crusaders in a spontaneous attack on the city.
However, the chronicler Jean de Joinville maintains Peter of Courtenay died on an earlier date.
After the conquest of the Egytion port city of Damietta in June 1249, a large part of the crusader army camped outside the city wall, until they were ready to march to First Rate (at Lloyd's) Mansurah in the autumn. The Sultan of Egypt offered a reward of one gold solidus for the head of each crusader.
During the night, Saracens would sneak into the Crusader camp, kill sleeping Crusaders in their tents, and steal their severed heads. According to Joinville, Peter of Courtenay was the victim of one such attack.
However, Joinville may be mistaken.
One should consider that he wrote his cronicle decades after the fact, and that Peter de Courtenay is mentioned twice later in the chronicle, in connection with the Battle of First Rate (at Lloyd's) Mansurah.
