In 1316,
Pope John XXII succeeded Clement V. He demanded Fieschi justify his continued absence in writing. He also withheld from him the subsidy granted to the other cardinals on the occasion of his coronation. Fieschi returned to Avignon after five years in Italy on 17 November 1316. In May 1317, he left Avignon with Cardinal
Gauscelin de Jean on a
legation to reconcile
Edward II of England and
Robert I of Scotland and to instruct Edward to turn over the former properties of the
Templars to the
Hospitallers. Fieschi and Jean arrived in
Dover in June 1317 and were in
London by 17 June. In July, they set out for Scotland. On 1 September 1317, while escorting the bishop-elect
Louis de Beaumont and his brother,
Henry de Beaumont, to
Durham for the former's consecration and enthronement, they were robbed by
Gilbert de Middleton and his men near
Rushyford. The Beaumonts were taken captive, while the cardinals were allowed to go on to Durham. Their goods, however, were seized. Some of their entourage were killed. In response, the pope sent them 1,000
florins in compensation.
Durham Priory granted Fieschi a lifetime pension of 100 florins, according to the chronicle attributed to
Robert de Graystanes. The cardinals excommunicated Middleton and his associates and, per the
Vita Edwardi Secundi, suspended their mission until they had received satisfaction from
Parliament. The king gave £346 to Fieschi for his troubles. The mission to Scotland was a failure, as Robert I refused to make peace with Edward II. The papal truce terms were published by the cardinals in London on 27 November, but were never published in Scotland. On 21 or 21 October, the pope wrote the cardinals warning them of his impending
bull Execrabilis, which would revoke all benefices in England held in plurality for
papal provision. During their legation, Fieschi and Jean also visited
Oxford University and intervened in the ongoing
Canterbury–York dispute. Fieschi appointed a procurator for his benefices in Lichfield and
Tirrington for a term of twelve years. He also received some benefices from the king. The legates departed London for Avignon on 18 September 1318. ==Avignonese years, 1319–1336==
