on. Before the battle began the prince prayed aloud to God that as he had come that day to uphold the right and reinstate a disinherited king, God would grant him success. Then, after telling Peter that he should know that day whether he should have his kingdom or not, he cried: 'Advance, banner, in the name of God and St. George; and God defend our right.' The knights of Castile pressed his van sorely, but the wings of Henry's army behaved ill, and would not move, so that the Gascon lords were able to attack the main body on the flanks. Then the prince brought the main body of his army into action, and the fight became hot, for he had under him 'the flower of chivalry, and the most famous warriors in the whole world.' At length Henry's van gave way, and he fled from the field (Ayala, xviii. c. 23; Froissart, vii. 37; Chandos, 1. 3107 sq.; Du Guesclin, p. 49). When the battle was over the prince besought Peter to spare the lives of those who had offended him. Peter assented, with the exception of one notorious traitor, whom he at once put to death, and he also had two others slain the next day.
Among the prisoners was the French marshal Audeneham, whom the prince had formerly taken prisoner at Poitiers, and whom he had released on his giving his word that he would not bear arms against him until his ransom was paid. When the prince saw him he reproached him bitterly, and called him 'liar and traitor.' Audeneham denied that he was either, and the prince asked him whether he would submit to the judgment of a body of knights. To this Audeneham agreed, and after he had dined the prince chose twelve knights, four English, four Gascons, and four Bretons, to judge between himself and the marshal. After he had stated his case, Audeneham replied that he had not broken his word, for the army the prince led was not his own; he was merely in the pay of Peter. The knights considered that this view of the prince's position was sound, and gave their verdict for Audeneham (Ayala).
On 5 April the prince and Peter marched to Burgos, and there kept Easter. The prince, however, did not take up his quarters in the city, but camped outside the walls at the monastery of Las Helgas. Peter did not pay him any of the money he owed him, and he could get nothing from him except a solemn renewal of his bond of the previous 23 Sept., which he made on 2 May before the high altar of the cathedral of Burgos (Fœdera, iii. 825). By this time the prince began to suspect his ally of treachery. Peter had no intention of paying his debts, and when the prince demanded possession of Biscay told him that the Biscayans would not consent to be handed over to him. In order to get rid of his creditor he told him that he could not get money at Burgos, and persuaded the prince to take up his quarters at Valladolid while he went to Seville, whence he declared he would send the money he owed. The prince remained at Valladolid during some very hot weather, waiting in vain for his money. His army sufiered so terribly from dysentery and other diseases that it is said that scarcely one Englishman out of five ever saw England again (Knighton, c. 2629). He was himself seized with a sickness from which he never thoroughly recovered, and which some said was caused by poison (Walsingham, i. 305). Food and drink were scarce, and the free companies in his pay did much mischief to the surrounding country (Chandos, 1. 3670 sq.) Meanwhile Henry of Trastamare made war upon Aquitaine, took Bagnères and wasted the country. Fearing that Charles of Navarre would not allow him to return through his dominions, the prince negotiated with the king of Aragon for a passage for his troops. The king made a treaty with him, and when Charles of Navarre heard of it he agreed to allow the prince, the Duke of Lancaster, and some of their lords to pass through his country; so they returned through Roncesvalles, and reached Bordeaux early in September. Some time after he had returned the companies, some six thousand strong, also reached Aquitaine, having passed through Aragon. As they had not received the whole of the money the prince had agreed to pay them, they took up their quarters in his country and began to do much mischief. He persuaded the captains to leave Aquitaine, and the companies under their command crossed the Loire and did much damage to France. This greatly angered Charles V, who about this time did the prince serious mischief by encouraging disaffection among the Gascon lords. When the prince was gathering his army for his Spanish expedition, the lord of Albret agreed to serve with a thousand lances. Considering, however, that he had at least as many men as he could find provisions for, the prince on 8 Dec. 1366 wrote to him requesting that he would bring two hundred lances only. The lord of Albret was much incensed at this, and, though peace was made by his uncle the Count of Armagnac, did not forget the offence, and Froissart speaks of it as the 'first cause of hatred between him and the prince.' A more powerful cause of this lord's discontent was the non-payment of an annual pension which had been granted him by Edward. About this time he agreed to marry
