In this way matters continued till February of the following year, 1516, when Sture resolved to attend the annual Upsala fair and have a conference with Trolle. The conference took place in presence of some of the leading men of Sweden, in the sacristy of the cathedral. But it led to no result. Trolle charged the regent with unfair dealing, which the latter denied, at the same time demanding proof. None was furnished; and the regent withdrew, feeling more than ever convinced that the conduct of the archbishop boded ill. In this juncture he summoned a Cabinet meeting, to be held at Telge in July following, to arrange the differences between himself and Trolle, and to resolve on the stand to be taken by Sweden in the congress of the three realms to be held at Halmstad in the February following. The archbishop, by virtue of his office, was a member of the Cabinet; but when that body met, it was discovered that Trolle was not present. He was in Upsala, nursing his wrath to keep it warm. The regent therefore wrote and begged him to appear. "Whatever," he wrote, "the Cabinet here assembled shall decide as right between us, I will do." But the proud archbishop would not listen. He and his father kept away, together with one or two of their adherents; and the Cabinet parted, having accomplished little.[23] Meantime the archbishop was not idle. Shortly before the Cabinet met, he with some of his adherents had held a conference at Stäket, where he had persuaded them to renounce the regent and form an alliance with the king of Denmark. While the Cabinet was in session, he despatched a messenger to King Christiern, urging him to break the truce with Sweden, and informing him that the Castle of Nyköping, now in the hands of one of the archbishop's satellites, should be thrown open to him if he would draw thither with his army. At the same time the archbishop began to fortify himself in Stäket. Learning this, the regent saw that the hour for compromise was past. He dissolved the Cabinet, and, advancing with all speed to Nyköping, stormed the castle. So rapid had been his action, that he took the archbishop's officers all unprepared, and at the first assault the garrison surrendered. This was on the 15th of August. After taking the officer in command of the garrison to Stockholm, where he was consigned to prison, the energetic young regent proceeded to Vesterås, where, on the 8th of September, in an address to the populace, he rendered an account of his actions, and informed the people that the archbishop and others were engaged in a plot to yield the kingdom into the hands of Christiern. Thence he proceeded to an island some six miles from Stäket, and remained there through the autumn, keeping an eye on the archbishop's castle and preparing, if necessary, to besiege it. The Danish party by this time saw that they were dealing with a man of mettle, and began to change their tactics. Hoping to gain time, they gave out that they would be glad to have the
