トロワ条約
Cromwell served Henry V at the Battle of Agincourt in 1415, and throughout the reign he continued fighting in France. In 1417 he was present when Henry took Caen by assault, and subsequently acted as Clarence's lieutenant and constable of the army. He was present at the capture of Courtonne on 6 March 1418, of Chambrays on the 9th, and of Rivière-Thibonville on the 11th. In May 1420 he was one of the commissioners who assisted Henry in negotiating the Treaty of Troyes.
