On March 12th, 1528, Margaret wrote to her secretary, Guillaume des Barres, from Malines, instructing him to 'go with all diligence to London to Monsieur de Burgues' (Iñigo de Mendoza, just appointed Bishop of Burgos),[133] the emperor's ambassador at that Court, and present his credentials, and tell him 'that we have received his letter of the 11th instant and heard of the overtures of peace made by the legate. We are indeed very happy,' she says, 'to see the good turn the affair is taking. You will tell him that we shall spare no personal trouble or fatigue to bring about a general peace,... though it seems to us, and indeed to almost all other people of honest intentions and quick understanding, that King Francis ought to have accepted at once the emperor's offers, by recalling his Italian army and giving up Genoa and his other conquests before his sons were actually released from captivity.... You will... request Mons. de Burgues to acquaint the legate with our readiness to help towards the accomplishment of peace,... that we have sent you for that purpose, and wish this affair to be conducted between us without the intervention of any other person whatsoever... and,' she adds, 'it is but proper that he himself (Wolsey) should have the honour of the affair since the proposal originated with him.' [133] It was then the custom in the Low Countries and also in France to designate bishops and archbishops by the names of their respective sees. A conference was held in London, and at Wolsey's request Margaret was invited to take in hand the arrangements for a general peace, and more particularly one between France and Spain. She was asked to work at it conjointly with the cardinal. Des Barres then proceeded to declare his mistress's intentions and wishes respecting the peace, expatiating at large on the evils resulting from the war to Christendom in general, and more particularly to the dominions and subjects of the emperor and the King of France, as it afforded the Turk every facility for an invasion, and encouraged the Lutheran heresy to spread far and wide. After discussing the subject at length, Wolsey begged Margaret immediately to send a messenger by land to the emperor, to acquaint him as soon as possible with the result of the conference held with his ambassadors, and the means which they and he conjointly propose for the furtherance of peace. The cardinal promised to apply for a safe conduct through French territory for the gentleman whom Madame Margaret might choose to appoint.[134] [134] _Calendar of Spanish State Papers._
