It will be seen by this, and nearly every other letter that Katharine wrote to her husband, that she had taken the measure of his prodigious vanity, and indulged him to the top of his bent. In a letter written to him on the 9th August, referring to the success of the Earl of Lennox, who had just married Henry's niece, Margaret Douglas, and had gone to Scotland to seize the government in English interest, Katharine says: "The good speed which Lennox has had, is to be imputed to his serving a master whom God aids. He might have served the French king, his old master, many years without attaining such a victory." This is the attitude in which Henry loved to be approached, and with such letters from his wife in England confirming the Jove-like qualities attributed to him in consequence of his presence with his army in France, Henry's short campaign before Boulogne was doubtless one of the pleasantest experiences in his life. To add to his satisfaction, he had not been at Calais a week before Francis began to make secret overtures for peace. It was too early for that, however, just yet, for Henry coveted Boulogne, and the sole use made of the French approaches to him was to impress the imperial agents with his supreme importance. The warning was not lost upon Charles and his sister the Queen Regent of the Netherlands, who themselves began to listen to the unofficial suggestions for peace made by the agents of the Duchess d'Etampes, the mistress of Francis, in order, if possible, to benefit herself and the Duke of Orleans in the conditions, to the detriment of the Dauphin Henry. Thenceforward it was a close game of diplomatic finesse between Henry and Charles as to which should make terms first and arbitrate on the claims of the other.
