later the Lyonnais castle of La Folleye. This campaign appears to have succeeded in its brief of the "protection and defence" of English France, and not only was Normandy almost cleared of enemy forces, the English even managed some "daring sorties" beyond the region. Although by now a leader of the royal armies in France, Rowena Archer suggests that it was around this time that his martial enthusiasm for royal service began to pale, at least in part because "it had owed much to his personal service to Henry V and to his office as marshal." But the new King was a baby, and with no further major campaigns taking place during the young king's minority, Mowbray's office of Earl Marshal was effectively unused. On 19 May 1426, the Duke of Bedford knighted the young king, who in turn dubbed a number of new knights from amongst the heirs of the nobility, including John Mowbray's son and namesake. Later career and death John Mowbray nearly drowned in the River Thames in November 1428 after his barge capsized after hitting a pier beneath London Bridge; he lost a number of his household in this accident. Mowbray was present in the council that same year which denounced the Duke of Gloucester's re-asserted attempt to increase his authority; Mowbray signed his name to an "astonished" memoranda that the duke would think of such a thing when the king was increasingly close to attaining his majority and with it being ready "to occupy his full royal power." By May 1429, he had written his first surviving will. The first major occasion on which he performed the office of Marshall again was the king's coronation at Westminster. Mowbray also took part in the first major campaign of Henry VI's reign which was a direct follow-on from the London coronation. In 1430 it was decided by the King's Council to crown Henry in both England, at Westminster Abbey, and then in France, hopefully in Paris. Mowbray contracted to bring a large force of 120 men-at-arms and 360 archers and led the army that accompanied the royal entourage. Mowbray, along with other members of the nobility, acted as both the kernel of the king's court and an experienced council while the king was in France. In an attempt to aid the Duke of Burgundy, Norfolk launched an assault on Gournay-sur-Aronde with 1,000 men and likewise took part
