Philip, however, refused to accept the returns, although not a single suffrage had been cast by the qualified electors for his son. He despatched the Bishop of Arras to Rome to petition the new pope, Calixtus III., to refuse to ratify the late election and to confer the see upon David, out of hand. Philip's tender conscience found Gijsbrecht ineligible to an episcopal office because he had participated in the war against Ghent, certainly a weak plea in an age of militant bishops! The pope was afraid to offend the one man in Europe upon whose immediate aid he counted in the Turkish campaign. He accepted the gift of four thousand ducats offered by Gijsbrecht's envoys, the customary gift in asking papal confirmation for a bishop-elect, but secretly he delivered to Philip's ambassador letters patent creating David of Burgundy Bishop of Utrecht.[5] The Burgundian La Marche states euphemistically that David was elected to the see, and the Deventer people would not obey him, therefore Philip had to levy an army and come in person to support the new bishop.[6] Du Clercq puts a different colour on the story and d'Escouchy[7] implies that the whole trouble arose from party strife which had to be quelled in the interests of law and order. Apart from any question of insult to the Utrechters by imposing upon them a spiritual director of acknowledged base birth, the right of choice lay with them and the emperor had confirmed their choice as far as the lay office was concerned. While the issue was undecided, the Estates of Utrecht appointed Gijsbrecht guardian and defender of the see to assure him a legal status pending the papal ratification. The people were prepared to support their candidate with arms, a game that Philip did not refuse, and the force of thirty thousand men with which he invaded the bishopric proved the stronger argument of the two and able to carry David of Burgundy to the episcopal throne, upon which he was seated in his father's presence, October 16, 1455. Some of Philip's allies reaped certain advantages from the situation. Alkmaar and Kennemerland redeemed certain forfeited privileges by means of their contributions to the duke's army. The city of Utrecht preferred a compromise to the risk of war. The bishop-elect, Gijsbrecht, consented to withdraw his claim, being permitted to retain the humbler office of provost of Utrecht and an annuity of four thousand guilders out of the episcopal revenues. Deventer was the only place which was obstinate enough to persist in her rebellion and Philip was engaged in bringing her citizens to terms by a siege when news was brought to him that a visitor had arrived at Brussels under circumstances which imperatively demanded his personal attention.
