After the truce had been established between Richard and Saladin, Peter was assigned an important mission with other household knights, including William des Roches and Gerard de Fournival. The crusading host had been permitted by the Muslims to complete the pilgrimage to Jerusalem. Peter, and his band, had been sent ahead of the first battalion to obtain safe conducts. According to the chronicle of the crusade attributed to Geoffrey of Vinsauf, Peter had fallen asleep at one of the villages where he was to meet a Saracen embassy. The crusaders charged ahead without receiving their safe conducts. When Peter and company had awaken, they realized that they were already behind the Christian host. Peter made all haste to catch up. He was then reprimanded by the column's commander, the king's cousin, Andrew of Chauvigny.
