Elated by his victory, the regent now opened communications once more with Trolle. With a view to frighten him into submission, he sent some of the Danish captives to Stäket, that the archbishop might hear from his own allies the story of their disaster. Even at this the proud spirit of the archbishop was not humbled. He still persisted in his determination not to yield, and it was only when his own officers began to leave him that he signified his willingness to withdraw from Stäket and retire to the duties of his cathedral. But now it was Sture's turn to dictate. He answered curtly that a murderer could no longer be archbishop, and proceeded at once to summon a general diet of the kingdom. This diet met at Stockholm in the last days of November. It was a notable gathering. Among those present were four of the six bishops,--all except the bishops of Vexiö and Skara,--of laymen, Hemming Gad and the father of young Gustavus, besides some ten other knights and armigers, the burgomaster and Council of Stockholm, and a large number of delegates from the peasantry. Before this assembly the archbishop appeared, under safe-conduct from the regent, to plead his cause. Among the witnesses produced in favor of the crown was a Danish officer captured in the battle outside Stockholm. This man testified, among other things, that before the Danish fleet set forth, a messenger from Trolle had appeared before King Christiern to solicit aid for Stäket. Indeed, the charge of conspiracy was proved beyond the shadow of a doubt. The whole house rose with one accord in denunciation of the traitor. Without a dissenting voice it was decreed that Stäket, "the rebel stronghold," should be levelled to the ground; that Trolle should nevermore be recognized as archbishop; that, though by the terms of his safe-conduct he might return to Stäket, he should not come forth therefrom till he had given pledge to do no further injury to the kingdom; and, finally, that if Trolle or any other in his behalf should solicit excommunication on any of those present for this resolve or for besieging or destroying Stäket, or should otherwise molest them, they all should stand firm by one another. This resolve, before the diet parted, was put into writing, and to it every member attached his seal.[28] The archbishop, as had been promised him, was permitted to return to Stäket, which was again put into a state of siege. The siege, however, was of short duration. Deserted by the largest portion of his officers, and with no immediate prospect of further aid from Denmark, the archbishop had nothing for it but to yield. Stäket thus fell into the hands of Sture; and the archbishop was placed in the monastery of Vesterås, to remain there captive till further disposition should be made of his archbishopric.[29]
