KING HENRY OF ENGLAND RETURNS TO FRANCE WITH A LARGE ARMY, AND TAKES MANY TOWNS AND FORTRESSES. THE COUNCIL OF CONSTANCE, WHERE POPE MARTIN IS ELECTED HEAD OF THE CHURCH. King Henry of England, accompanied by his brothers the dukes of Clarence and Glocester, a number of other nobles, and a numerous army, landed at the Port of Touques in Normandy, with the intent to conquer the whole of that duchy. The royal castle at Touques was speedily invested on all sides, which caused the governor, sir John d'Engennes, to surrender it within four days, on condition that he and the garrison should depart with their effects. Within a short time afterward, the following towns and castles surrendered to king Henry without making any resistance: Harcourt, Beaumont le Roger, Evreux, and several others, in which he placed numerous garrisons. He then opened negotiations for the surrender of the towns of Rouen and Louviers. The other towns in the duchy were astonished at the facility of king Henry's conquests, for scarcely any place made a defence. This was caused by the divisions that existed among the nobles, some taking part with the king and others with the duke of Burgundy, and therefore they were fearful of trusting each other. The constable had besides drawn off the greater part of the forces in this district to Paris, to be prepared to meet the duke of Burgundy, whom he daily expected in those parts with a large army. At this period, by orders from the holy council at Constance, Italy, France, England and Germany, selected four discreet men from each nation, who entered the conclave with the cardinals of the roman court, to elect a pope, on the eve of Martinmas-day. During the time they were shut up in conclave, Sigismund emperor of Germany, and king of Hungary and Bohemia, was seated on his royal throne without the doors of the conclave, having on his head an imperial crown, and in his hand the sceptre, surrounded by a numerous body of princes, knights, and men at arms.
