Coutances to France on another diplomatic mission. In February 1182 Coutances witnessed King Henry II's will, made before the king travelled to Normandy. Bishop of Lincoln and Archbishop of Rouen Coutances was elected to the see of Lincoln on 8 May 1183, selected by King Henry over three other candidates. He was ordained a priest on 11 June 1183 and consecrated bishop on 3 July 1183 at Angers by Richard of Dover, the Archbishop of Canterbury. He was enthroned at Lincoln Cathedral on 11 December 1183. While at Lincoln, Coutances took part in the election of Baldwin of Forde as the new Archbishop of Canterbury, which took place at a council held in Westminster in 1184. Writing about Coutances' time at Lincoln, Gerald of Wales accused the bishop of increasing the debt of the diocese of Lincoln and of squandering its resources. Coutances helped the schools in the city of Lincoln, acting as the patron for scholars such as John of Tynemouth and Simon of Southwell. On 17 November 1184 Coutances was translated to the diocese of Rouen, becoming Archbishop of Rouen. The original election to Rouen had taken place in the summer. King Henry had initially rejected the Rouen cathedral chapter's nominees and put forward three English bishops as the royal candidates. The king also indicated his preference that Coutances be elected, a choice that was confirmed by the pope in November. Coutances hesitated about the translation to Rouen, as the see there was poorer than Lincoln, but as an archbishopric rather than a bishopric it was of a higher status. The medieval chronicler William of Newburgh wrote that eventually Coutances' ambition overcame his greed, and he agreed to the translation. He was received at Rouen on 3 March 1185. Coutances remained in Henry's service however, and continued attend the royal court frequently. During the final 10 years of Henry's reign, only Ranulf de Glanville witnessed more royal charters, and only William de Humez, the constable, equalled the 16 charters that Coutances witnessed. In the later part of 1186, after the death of King Henry's son Geoffrey—who was Duke of Brittany—King Philip II of France demanded that Geoffrey's daughters be placed in the French king's custody, and that the duchy of Brittany, which Geoffrey had ruled in right of his wife, be surrendered into French royal custody. Coutances was one of the negotiators sent by King Henry to secure
