Burgundy dared not concede so much, under pain of alienating all his more patriotic supporters. He broke off the conference of Meulan, and tried to patch up a peace with the dauphin, in order to unite all Frenchmen against the foreign invader. This laudable intention was wrecked by the treachery of the young heir to the French throne; on the bridge of Montereau Charles deliberately murdered the suppliant duke, as he knelt to do homage, thinking thereby that he would make an end of the Burgundian party (Sept. 9, 1419). The Burgundians acknowledge Henry as heir of France. Treaty of Troyes. This abominable deed gave northern France for twenty years to an English master. The young duke of Burgundy, Philip the Good, and his supporters in Paris and the north, were so incensed with the dauphin's cruel treachery that they resolved that he should never inherit his father's crown. They proffered peace to King Henry, and offered to recognize his preposterous[4] claim to the French throne, on condition that he should marry the princess Catherine and guarantee the constitutional liberties of the realm. The insane Charles VI. should keep nominal possession of the royal title till his death, but meanwhile the Burgundians would do homage to Henry as "heir of France." These terms were welcomed by the English king, and ratified at the treaty of Troyes (May 21, 1420). Henry married the princess Catherine, received the oaths of Duke Philip and his partisans, and started forth to conquer the Dauphinois at the head of an army of which half was composed of Burgundian levies. Paris, Picardy, Champagne, and indeed the greater part of France north of the Loire, acknowledged him as their sovereign. Death of Henry V. Henry had only two years longer to live; they were spent in incessant and successful campaigning against the partisans of his brother-in-law, the dauphin Charles; by a long series of sieges the partisans of that worthless prince were evicted from all their northern strongholds. They fought long and bitterly, nor was this to be marvelled at, for Henry had a custom of executing as traitors all who withstood him, and those who had once defied him did well to fight to the last gasp, in order to avoid the block or the halter. In the longest and most desperate of these sieges, that of Meaux (Oct. 1421-March 1422), the king contracted a dysenteric ailment which he could never shake off. He survived for a few months, but died, worn out by his incessant campaigning, on the 31st of August 1422, leaving the crown of England and the heirship of France to his only child Henry of Windsor, an infant less than two years old.
