to Leopold for the remaining twenty thousand. When these hostages and the first hundred thousand marks were all received, Richard was to be set free. There was, however, an alternative: “If the king should fulfill the promise which he formerly made to the Emperor concerning Henry sometime Duke of Saxony, the Emperor, letting the king off fifty thousand marks, shall pay for him twenty thousand to the Duke of Austria”; no hostages would then be required, and Richard should be liberated as soon as the hundred thousand [Sidenote: _June 29_] marks were paid and his promise fulfilled. Furthermore, Richard took an oath that in either case he would within seven months of his return home send his niece to Germany to be married to Leopold’s son.[1108] What was the promise which Richard had made to the Emperor concerning Henry the Lion, when it was made, and whether or not it was ever fulfilled, we cannot tell; the only known mention of the matter is the passage quoted above. From the fact that Richard did on his release leave some hostages in Germany we might infer that he had not done what he had promised; but this inference is doubtful, for we shall see that the conditions of his release were altered again before Henry let him go. Richard’s next step was to seize his opportunity, while negotiations between Henry and Philip were at a standstill, to make overtures to Philip. Immediately after the council at Worms he despatched William of Ely to France with orders to make “some sort of a peace” for him with the king. This William did at Mantes on July 9. The terms consisted of a promise in Richard’s name that he would leave to Philip’s discretion the disposal of whatever territories within the Angevin dominions were then occupied by Philip himself or by his men; that he would perform the homages and services due for all and each of his French fiefs, would grant an amnesty and restitution of their lands to certain of his vassals[1109] who had incurred forfeiture, and would clear off the debt which, it seems, Philip still claimed under the treaty of 1189, by paying him twenty thousand marks in half-yearly instalments of five thousand marks each, the first instalment to be paid within six months after the payer’s release from captivity, and Philip meanwhile to hold in pledge the castles of Loches, Châtillon-sur-Indre, Driencourt and Arques; one of these to be restored to Richard on the payment of each instalment of the money. Philip promised that meanwhile, as soon as the castles were placed in his custody, he would “receive the King of England into his favour and make request to the Emperor for his liberation.”[1110]
