The entire subjection of Italy to the Emperor was drawing closer the French alliance, and a new treaty had been concluded in April. But this had hardly been signed when the sack of Rome and the danger of the Pope called for bolder measures. Wolsey was despatched on a solemn embassy to Francis to promise an English subsidy on the despatch of a French army across the Alps. But he aimed at turning the Pope's situation to the profit of the divorce. Clement was virtually a prisoner in the castle of St. Angelo; and as it was impossible for him to fulfil freely the function of a Pope, Wolsey proposed, in conjunction with Francis, to call a meeting of the college of cardinals at Avignon which should exercise the papal powers till Clement's liberation. As Wolsey was to preside over this assembly, it would be easy to win from it a favorable answer to Henry's request. But Clement had no mind to surrender his power, and secret orders from the Pope prevented the Italian cardinals from attending such an assembly. Nor was Wolsey more fortunate in another plan for bringing about the same end by inducing Clement to delegate to him his full powers westward of the Alps. Henry's trust in him was fast waning before these failures and the steady pressure of his rivals at court, and the coldness of the King on his return in September was an omen of his minister's fall. Henry was in fact resolved to take his own course; and while Wolsey sought from the Pope a commission enabling him to try the case in his legatine court and pronounce the marriage null and void by sentence of law, Henry had determined at the suggestion of the Boleyns and apparently of Thomas Cranmer, a Cambridge scholar who was serving as their chaplain, to seek, without Wolsey's knowledge, from Clement either his approval of a divorce or, if a divorce could not be obtained, a dispensation to remarry without any divorce at all. For some months his envoys could find no admission to the Pope; and though in December Clement succeeded in escaping to Orvieto and drew some courage from the entry of the French army into Italy, his temper was still too timid to venture on any decided course. He refused the dispensation altogether. Wolsey's proposal for leaving the matter to a legatine court found better favor; but when the commission reached England it was found to be "of no effect or authority." What Henry wanted was not merely a divorce but the express sanction of the Pope to his divorce, and this Clement steadily evaded. A fresh embassy, with Wolsey's favorite and secretary, Stephen Gardiner, at its head, reached Orvieto in March, 1528, to find, in spite of Gardiner's threats, hardly better success; but Clement at last consented to a legatine commission for the trial of the case in England. In this commission Cardinal Campeggio, who was looked upon as a partisan of the English King, was joined with Wolsey.
