The overtures to England which Charles had commenced on the death of Catherine, had been checked by Henry's haughty answer; and Charles had replied by an indirect countenance, through his ambassador, to Pole,[326] and to Lord Darcy. But the motives which had led to these overtures remained to invite their renewal; the insurrection was for the present prostrate, and the emperor therefore withdrew his first step, and disowned his compromised minister in London. In June, 1537, Diego de Mendoza arrived at the English court, with a commission to express in more emphatic terms the earnest wish of the court of Spain for the renewal of the old alliance. [Sidenote: Sir Thomas Wyatt goes on a extraordinary mission into Spain.] [Sidenote: Henry desires to forget the past and renew his friendship with the Emperor;] [Sidenote: Subject to certain conditions.] The king had done enough for the protection of his dignity; prudence now recommended him to believe in Charles's sincerity. A solid understanding with Flanders was the best passport to the hearts of large portions of his subjects, whose interests were connected with the wool trade: he was himself ardently anxious to resume his place in the fraternity of European sovereigns. Mendoza was graciously received. Sir Thomas Wyatt was despatched into Spain with a corresponding mission; and Wyatt's instructions were couched in language which showed that, although the English government were under no delusion as to Charles's late proceedings, they were ready to close their eyes to objects which they did not wish to see. The proposals for a reconciliation which had been made by the late ambassadors had appeared so feeble, Wyatt was to say, as to seem rather a device of policy to prevent the King of England from allying himself with France, than as intended in sincerity; M. de Mendoza, however, had removed all such unpleasant impressions; and although, if the Emperor would consider the past differences between the two courts impartially, he must feel that the fault rested with himself, yet the English government, on their side, were ready to set aside all painful recollections.[327] There were persons, indeed, who affirmed that the Emperor was still trifling, that Mendoza was playing a game, and that, in "heart, deed, and words," the Spanish court were "doing all they could to his Majesty's dishonour."[328] Nay, even individuals could be found who boasted themselves to have refused some honest offers because they were "knit with vile and filthy conditions towards his Majesty."[329] The king, however, set aside these rumours, as either without foundation, or as belonging to the past rather than the present. He required only, as a condition or renewed friendship, that if the Pope found the means of attacking England, Charles should bind himself to be no party to such an enterprise, but should oppose it "to the uttermost of his power."[330] In return, the Emperor might perhaps require that
