At that time news came that the Duke of Lancaster had married his daughter Catherine [aged 15] to the son and heir of the King of Spain [aged 8], for which marriage he received a very great quantity of gold. But peace between the kingdom of England and Spain could by no means be obtained through this, because the King of Spain was so closely allied with the King of France that peace between us could in no way be restored without his assent.
Quo in tempore venerunt nova quomodo dux Lancastriæ copulavit filiam suam Katerinam filio et heredi regis Hispaniæ pro cujus copulatione multam immo et magnam copiam auri recepit, sed pax inter regnum Angliæ et Hispaniæ nullatenus per hoc potuit obtineri, quia in tantum erat rex Hispaniæ regi Francorum confæderatus quod nullo modo sine ejus assensu pax inter nos potuit reformari.

The duke of Lancaster [aged 48] also, claiming the kingdom of Spain in right of his wife [aged 34], sailed to that country two years after, with another crusade; and there he lost by the same sickness many of the nobles of the realm of England, and, I may say, the flower of its youthful chivalry. Yet he made peace with the king of Spain, receiving a duchy for the term of his life, and a large sum of gold for his outlay, and giving his daughter [aged 15] in marriage to the king's eldest son [aged 8]; and so he returned to England1.

Froissart Book 4 Chapter 95. 16th September 1398. Not long after this, the king of England [aged 31] summoned a large council of the great nobles and prelates at Eltham [Map]. On their arrival, he placed his two uncles of Lancaster [aged 58] and York [aged 57] beside him, with the earls of Northumberland [aged 56], Salisbury [aged 48] and Huntingdon [aged 46]. The earl of Derby [aged 31] and the earl marshal [aged 30] were sent for, and put into separate chambers, for it had been ordered they were not to meet. The king showed he wished to mediate between them, notwithstanding their words had been very displeasing to him, and ought not to be lightly pardoned. He required therefore that they should submit themselves to his decision; and to this end sent the constable of England, with four great barons, to oblige them to promise punctually to obey it. The constable and the lords waited on the two earls, and explained the king's intentions. They both bound themselves, in their presence, to abide by whatever sentence the king should give. They having reported this, the king said, "Well then, I order that the earl marshal, for having caused trouble in this kingdom, by uttering words which he could not prove otherwise than by common report, be banished the realm: he may seek any other land he pleases to dwell in, but he must give over all hope of returning hither, as I banish him for life. I also order, that the earl of Derby, our cousin, for having angered us, and because he has been, in some measure, the cause of the earl marshal's crime and punishment, prepare to leave the kingdom within fifteen days, and be banished hence for the term of ten years, without daring to return unless recalled by us; but we shall reserve to ourself the power of abridging this term in part or altogether." The sentence was satisfactory to the lords present, who said: "The earl of Derby may readily go two or three years and amuse himself in foreign parts, for he is young enough; and, although he has already travelled to Prussia, the Holy Sepulchre, Cairo and Saint Catherine's1, he will find other places to visit. He has two sisters, queens of Castillo [aged 25] and of Portugal [aged 38], and may cheerfully pass his time with them. The lords, knights and squires of those countries, will make him welcome, for at this moment all warfare is at an end. On his arrival in Castille, as he is very active, he may put them in motion, and lead them against the infidels of Granada, which will employ his time better than remaining idle in England. Or he may go to Hainaut, where his cousin, and brother in arms, the count d'Ostrevant, will be happily to see him, and gladly entertain him, that he may assist him in his war against the Frieslanders. If he go to Hainaut, lie can have frequent intelligence from his own country and children. He therefore cannot fail of doing well, whithersoever he goes; and the king may speedily recall him, through means of the good friends he will leave behind, for he is the finest feather in his cap; and he must not therefore suffer him to be too long absent, if he wish to gain the love of his subjects. The earl marshal has had hard treatment, for he is banished without hope of ever being recalled; but, to say the truth, he has deserved it, for all this mischief has been caused by him and his foolish talking: he must therefore pay for it." Thus conversed many English knights with each other, the day the king passed sentence on the earl of Derby and the earl marshal.
