On 5 April 1367 the prince and Peter marched to Burgos, where they celebrated Easter. The prince, however, did not take up his quarters in the city, but camped outside the walls at the Monastery of Las Huelgas. Peter did not pay him any of the money he owed him, and the prince could get nothing from him except a solemn renewal of his bond of the previous 23 September, which he made on 2 May 1367 before the high altar of the Cathedral of Burgos. 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 Peter 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.
