[Footnote 171: Henry's own words, in a letter, 21 July 1418, sent from Pont de Larche to the Mayor of London, are: "Since our last departing from Caen, we came before our town of Louviers, and won it by siege; to which place came to us the Cardinal of Ursin from our holy father the Pope, for to treat for the good of peace betwixt both realms, and is gone again to Paris to diligence there in this same matter; but what end it shall draw to we wot not as yet." In this letter he informs us that the attack on Pont de Larche was on the 4th of July; and that, though the enemy had "assembled in great power to resist us, yet God of his mercy showed so for us and for our right, that it was withouten the death of any man's person of ours." He adds that he had just heard of the decidedly hostile intentions of the Duke of Burgundy towards him; so "we hold him our full enemy. He is now at Paris." The King then tells them that he needs not to refer to the death of the Earl of Armagnac, and the slaughter that hath been at Paris; for he was assured that they had full knowledge thereof. He alludes to the massacre of the Armagnac faction by the partisans of the Duke of Burgundy, June 12, 1418. Two thousand persons were murdered in a very brief space of time. The mob dragged the bodies of the Constable and Chancellor through the streets (as Monstrelet tells us) for two or three days.] The citizens of Rouen, which was well garrisoned, and had an ample store of provisions, had declared themselves for the Duke of Burgundy; but now, in their alarm, they supplicate aid from the Dauphin against the common enemy. His answer was, that he was compelled to employ his troops in defending his own towns against the Duke of Burgundy.[172]
