Santarem, and once there with his beloved, he forgot his oath, and sent all the troops he could collect to punish the rioters of Lisbon. They made but little resistance, being unprepared for their sovereign’s want of faith to his plighted word, and Fernan Vasques, the tailor, and his principal followers were beheaded. This cruel punishment inflicted, the king betook himself to Oporto, and there married the Donna Leonor at the Church of S. João do Hospital, although her first husband was still alive. It shows to what a depth of degradation the Portuguese nobles had sunk that all the nobility, with the exception of Dom Diniz, one of the king’s half-brothers, acquiesced in this bigamous marriage, and recognized Donna Leonor as queen. At the head of those who submitted were Dom João or John, the elder son of the late king by Ines de Castro, and Dom John, known as “the Bastard,” the Master of the Knights of Aviz, and the son of Pedro by Theresa Lourenço. The people of Lisbon were right in believing that the Castilians would regard the marriage of Ferdinand to Donna Leonor as a deadly insult to their infanta. Henry II. at once invaded Portugal, and laid siege to Lisbon; Ferdinand lived meanwhile quietly at Santarem with his queen, and made no effort to intervene; and the war would have ended badly for Portugal, had not Cardinal Guy of Boulogne, who happened to be in Spain as legate, interfered, and by using all the authority of the Church, forced Henry II. to retire, and to make a treaty of peace with Ferdinand at Santarem. Even after this proof of the power of Castile, and after the sufferings incurred by the people of Lisbon during the siege, Ferdinand refused to keep the peace. He would not believe that Henry II. was firmly established on the throne, and in 1373 he treacherously renewed the negotiations which he had entered into the year before with John of Gaunt, Duke of Lancaster. This son of Edward III. claimed the throne of Castile for his wife Constance, the daughter of Pedro “the Cruel,” and Ferdinand signed a treaty of alliance with Edward III., through his ambassadors, João Fernandes Andeiro and Vasco Domingues, by which he agreed to support the claims of the English prince. But Donna Leonor did not approve of the English alliance, and in 1374, Ferdinand as usual broke his plighted word, and again made peace with Castile.
