In 1521, when war had already broken out between the two great powers, the cardinal in his King's name undertook the part of mediator. There in Calais he sat to a certain degree in judgment on the European powers. The plenipotentiaries of both sovereigns laid their cases before him: with apparent zeal and much bustle he tried at least to conclude a truce: he complained once of the Emperor, that he disregarded his good advice though weighty and to the point: on which the latter did come a step nearer him. It was a magnificent position if he understood and maintained it. The more powerful both princes became, the more dangerous to the world their enmity should be, the more need there was of a mediating authority between them. But the purity of intention which is required to carry out such a task is seldom given to men, and did not exist in Wolsey. His ambition suggested plans to him which reached far beyond a peace arbitration. When he promoted that first interview with Francis I against the will of the great men and of the Queen of England, the Emperor's ambassadors, who were thrown into consternation by it, remarked that the French King must have promised him the Papacy, which however, they add, is rather in the Imperial than in the royal gift. It does not appear that the Emperor went quite so far at once, he only warned the cardinal against the untrustworthy promises of the French, and sought to bring him to the conviction--while making him the most advantageous offers--that he could expect everything from him.[82] Clear details he reserved till they met in person; and then he in fact drew him over completely to his side. Under Wolsey's influence King Henry, immediately on the outbreak of the war, gave out his intention of making common cause with the Emperor. For he had not, he said, so little understanding as not to see that the opportunity was thus offered him of carrying out his predecessors' claims and his own, and he wished to use it. Only he preferred not to commence war at once, since he was not yet armed, and since a broader alliance should be first formed. The cardinal hoped to be able to draw the Pope, the Swiss, and the Duke of Savoy, as well as the Kings of Portugal, Denmark, and Hungary, into it. What an impression then it must have made on him, when Pope Leo X, without being pressed, at once allied himself with the Emperor! Wolsey's attempt at mediation--no room for doubt about it is left by the documents that lie before us--was only meant as a means of gaining time. At Calais Wolsey had already given the imperial ambassadors, in the presence of the Papal Nuncio, the most definite assurances as to the resolution of his King to take part in the war against France. Before he returned to England to call the Parliament together, which was to vote the necessary ways and means, he visited the Emperor at Bruges. At the last negociations, being at times doubtful about his trustworthiness, Charles V held it doubly
