Pons was in the army of Count Raymond IV of Toulouse, and accompanied the count into the church of Saint Peter in Antioch at the discovery of the Holy Lance on the evening of 14 June 1098. He died at the siege of Arqa in 1099 before the capture of Jerusalem. According to Archbishop William II of Tyre, "before the walls of Arka ... Pons de Balazune, a nobleman of high rank and a friend of the count of Toulouse ... perished from the blow of a stone missile" alongside Anselm de Ribemont. He was sufficiently prominent in the count's following to be mentioned by several independent accounts of the crusade. He is mentioned in the "Historia Hierosolymitana", the "Historia de Hierosolymitano itinere", the "Historia peregrinorum" and the "Historia de via Hierosolymitana".
