Since this was the surest way to win both Henry's and Cromwell's favour, Wyatt made unscrupulous use of these slanders to poison William of Cleves's mind against the Duchess whose hand he sought. On the 13th of April the Duke arrived at Ghent, and was met by the Prince of Orange, who brought him to King Ferdinand's rooms. Late the same evening the English Ambassador had a secret interview with him, and did his utmost to dissuade him from entering into any treaty with the Emperor. The Duke's irresolution was now greater than ever. The next day Ferdinand himself conducted him into the Emperor's presence, where he received the most friendly greeting, and was invited to join the imperial family at dinner. The gracious welcome which he received from Mary, and the sight of Christina, went far to remove his doubts, and during the next few days the harmony that prevailed among the Princes excited Wyatt's worst misgivings. The Venetian Ambassador, Francesco Contarini, met the Countess Palatine returning from Ghent, and heard from her servants that a marriage was arranged between her sister and the Duke of Cleves. Monsieur de Vély, the French Envoy, sent this report to Paris, and it was confidently asserted at the French and English Courts that Cleves had settled his quarrel with the Emperor, and was to wed the Duchess.[286] [Sidenote: MAY, 1540] AN ABRUPT DEPARTURE] But these reports were premature. The Duke told Wotton and Wyatt that nothing would induce him to give up Guelders, and at their suggestion he placed a statement of his claims in the hands of Ferdinand, who promised to submit the document to the Emperor. During the next fortnight the question was discussed in all its bearings by Charles and his Councillors. The Duke pressed his suit for the Duchess's hand, and the Emperor went so far as to offer him the reversion of Denmark if he would renounce Guelders. But William was as obstinate as the Emperor, and, when Ferdinand induced Charles to offer Cleves his niece and the duchy of Guelders for his lifetime, he quite refused to accept this proposal. All Ferdinand could persuade him to do, was to consent that the question of Guelders should be referred to the Imperial Chamber, a compromise which satisfied neither party. Still friendly relations were maintained outwardly. On Sunday, the 27th of April, the imperial family attended Mass in state, the Emperor riding to the Church of St. John with the King of the Romans and the boy Legate, Cardinal Farnese, on his left, followed by the Dukes of Brunswick, Cleves, Savoy, and the Marquis of Brandenburg. In the afternoon Ferdinand sent for the Duke again, and made one more attempt to arrange matters, without success. Some insolent words spoken by Cleves's servants aroused the Emperor's anger, upon which the Duke became alarmed, and sent Wotton word that, seeing no hope of agreement, he intended to return home. Early the next morning, without taking leave of anyone, he rode out of the town
