 Warelwast may have been with the hunting party on 2 August 1100 in which King William was accidentally killed, as he was one of the witnesses to the letter sent on 5 August 1100 from William IIs brother, the new King Henry I to Anselm recalling the archbishop. King Henry continued to use Warelwast as an ambassador, sending him to Rome in 1101 to bring back Pope Paschal II's reply to a letter written by Henry immediately after his accession. Henry was seeking a reconciliation with the papacy, and confirmed to the pope the rights and obedience which his father had rendered, but he also requested the same rights within the Church as his father had enjoyed, chiefly the lay investiture of bishops and the granting of the symbols of episcopal authority by laymen. Paschal declined to grant Henry those rights.
