Henry V. on his accession bade farewell to the faults of his youth. He seems to have felt a genuine regret for the unfilial conduct which had vexed his father's last years, and showed a careful determination to turn over a new leaf and give his enemies no scope for criticism. From the first he showed a sober and grave bearing; he reconciled himself to all his enemies, gave up his youthful follies, and became a model king according to the ideas of his day. There is no doubt that he had a strong sense of moral responsibility, and that he was sincerely pious. But his piety inspired him to redouble the persecution of the unfortunate Lollards, whom his father had harried only in an intermittent fashion; and his sense of moral responsibility did not prevent him from taking the utmost advantage of the civil wars of his unhappy neighbours of France. Persecution of the Lollards. Rising under Oldcastle. The first notable event of Henry's reign was his assault upon the Lollards. His father had spared their lay chiefs, and contented himself with burning preachers or tradesmen. Henry arrested John Oldcastle, Lord Cobham, their leading politician, and had him tried and condemned to the stake. But Oldcastle escaped from the Tower before the day fixed for his execution, and framed a wild plot for slaying or deposing his persecutor. He planned to gather the Lollards of London and the Home Counties under arms, and to seize the person of the king--a scheme as wild as the design of Guy Fawkes or the Fifth Monarchy Men in later generations, for the sectaries were not strong enough to coerce the whole nation. Henry received early notice of the plot, and nipped it in the bud, scattering Oldcastle's levies in St Giles' Fields (Jan. 10, 1414) and hanging most of his lieutenants. But their reckless leader escaped, and for three years led the life of an outlaw, till in 1417 he was finally captured, still in arms, and sent to the stake. Henry V. and France. This danger having passed, Henry set himself to take advantage of the troubles of France. He threatened to invade that realm unless the Orleans faction, who had for the moment possession of the person of the mad king Charles VI., should restore to him all that Edward III. had owned in 1360, with Anjou and Normandy in addition. The demand was absurd and exorbitant and was refused, though the French government offered him the hand of their king's daughter Catherine with a dowry of 800,000 crowns and the districts of Quercy and Périgord--sufficiently handsome terms. When he began to collect a fleet and an army, they added to the offer the Limousin and other regions; but Henry was determined to pick his quarrel, and declared war in an impudent and hypocritical manifesto, in which he declared that he was driven into strife against his will. The fact was that he had secured the promise of the neutrality or the co-operation of the Burgundian faction, and thought that he could crush the Orleanists with ease.
