again with the king, this time accepting the captaincy of Pontoise and contracting to provide 60 men-at-arms and 180 archers for the purpose. This appointment—Rowena Archer described it as an "onerous" one—was sufficient to prevent Mowbray from accompanying the King to England. Mowbray was only able to travel with Henry as far as Amiens; the king had just married Katherine of Valois, and they were travelling to England for her coronation. Mowbray should have attended per his office of Earl Marshal; the Earl of Worcester deputised for him. Similarly, when Mowbray was elected to the Order of the Garter, his installation had to be received for him by Rowland Lenthal, later High Sheriff of Hertfordshire. With the Duke of Gloucester What has been described as a "curious" episode in Mowbray's career occurred in 1424. Already friends with Humphrey, Duke of Gloucester, when the duke decided to invade the county of Hainaut in November that year, Mowbray journeyed with him and acted as his military commander. Little is known of this expedition except that, having raided Brabant, it was probably profitable for Mowbray. Under Henry VI Mowbray was still in France when King Henry returned in 1421, maintaining a front line at Vermandois, Tierche and the Laonnois against La Hire and Jean Poton de Xaintrailles. It was only when the king died unexpectedly on 31 August 1422 that the earl returned to England accompanying the corpse. He attended parliament that year, although he was summoned under the name "Thomas," and Archer posits that that clerical error is indicative of how little, due to his French service, he was known in England. He also joined the royal council that the recent parliament had ordained would govern the country through the new King's long minority. Ralph Griffiths has also suggested that Norfolk's admission to that body "provided an injection of youth into discussions hitherto conducted by a rather elderly group." He was not a particularly regular attendee to the council, and within a year, he had contracted again to serve abroad, on this occasion bringing 115 men-at-arms and 300 archers with Lords Willoughby, Hungerford, and the Duke of Exeter. Although Mowbray did not participate in the Battle of Cravant, which took place on 31 July 1423, he was not inactive; having taken part in so many sieges in his career, he was assisting Jean de Luxembourg in his efforts to relieve Bohain, and
