that in spite of this spirit of reconciliation, none of the heirs received outright their treacherous fathers' lands, and that this, therefore, made John Mowbray more likely to be "dependent on the crown" for additional sources of income. G. L. Harriss described Mowbray as "younger than the king and anxious to recover forfeited lands and titles and restore... family honour". King Henry IV died in March 1413 and was succeeded by his eldest son, who became Henry V. It was probably at his coronation, on 9 April that year, that Mowbray first exercised his office of Earl Marshal, and as a fee, he was paid with a silver dish, worth approximately twenty-five marks. Furthermore, one of the old King's last acts, in early March, had been to restore Mowbray to full seisin of his estates, and to confirm him as Earl of Nottingham. Two days after the king's death, the earl was summoned to the parliament for the first time; however, he "continued to badger" the new king, Henry V, for the restoration of his full estates. Military service in France Under Henry V By the spring of 1414, the new king was publicly reiterating the claim to the French throne that English Kings had traditionally upheld. By April the next year, Mowbray indentured with the King for military service in France, contracting to supply four knights, forty-five men at arms, and 150 archers. On top of military personnel, Mowbray's extant accounts indicate that he also had to pay not only for materiél (such as tents, horses, armour, weapons and livery), but for support staff such as surgeons, priests, armourers and cooks. Providing this contingent and other preparations cost him £2,500, of which, eventually, only £1,450 was returned to him in campaign wages. So poor were Mowbray's finances at this time that he had had to borrow 1,000 marks from the Earl of Arundel; worse, he had to resort to the "dubious practice" of claiming that innocent—but prosperous—townsmen (from Norwich, for example) were in fact runaway villeins, and effectively blackmailed them with manumission fines. The Agincourt campaign ultimately cost Mowbray £1,000 more than he was paid. The King's expedition was due to leave from Southampton in August 1415; just before it did, however, a treasonous plot against Henry V was uncovered, which involved his cousin, Richard, Earl of Cambridge. In his capacity as Earl Marshal, Mowbray led the investigation into
