Don Pedro still counted many adherents in the country. Most of the Jewish communities remained true to him, and Jews served in his army, and fought against the usurper for the king, who to the last treated them with special favor. Even when in despair he was obliged to call to his assistance the Mahometan king of Granada, he impressed upon that monarch the duty of protecting the Jews. Notwithstanding this, the Jews endured indescribable sufferings at the hands of both friend and foe. Don Pedro being entirely dependent on the auxiliaries of the Black Prince and on those of the Mahometan king, his wishes with respect to the Jews were not regarded. The community of Villadiego, celebrated for its benevolence and the promotion of learning, was utterly destroyed by the English. The same evil fortune befell Aguilar and other communities. The inhabitants of Valladolid, who paid allegiance to Don Henry, plundered the Jews, demolished their eight synagogues, despoiled them of their treasures, and tore up the sacred writings. A period of shocking degeneracy followed. Wherever Don Henry came, he laid the Jews under heavy contributions, precipitating them into poverty, and leaving them nothing but their lives. The Mahometan king, Don Pedro's ally, carried three hundred Jewish families as prisoners from Jaen to Granada. Still worse was the treatment of the violent Du Guesclin. A prey to French Jew-hatred, he could not look upon Jews as his equals in party strife and war, but only as slaves who had dared draw the sword against their masters. The misery was so great at this time that many Jews became converts to Christianity.
