A few days after, Corfits Ulfeldt and Leonora Christina left Copenhagen, which he was never to see again, she only as a prisoner. They retired to the estate of Ellensborg, in Fyen, which they had still retained. This was the ancient seat of the Ulfeldts, which Corfits' father had sold to Ellen Marsvin, Leonora Christina's grandmother, and which had come to Leonora through her mother. In the meanwhile it had been renamed and rebuilt such as it stands to this day, a picturesque pile of buildings in the Elizabethan style. Here Ulfeldt might have ended his stormy life in quiet, but his thirst for revenge left him no peace. Besides this, a great change had taken place in Denmark. The national revival which followed the renewal of the war by Carl Gustav in 1658 led to a total change in the form of government. It was indisputable that the selfishness of the nobles, who refused to undertake any burden for the defence of the country, was the main cause of the great disasters that had befallen Denmark. The abolition of their power was loudly called for, and the Queen so cleverly turned this feeling to account, that the remedy adopted was not the restoration of the other classes of the population to their legitimate constitutional influence, but the entire abolition of the constitution itself, and the introduction of hereditary, unlimited despotism. The title 'hereditary king,' which so often occurs in Danish documents and writings from that time, also in Leonora's Memoir, has reference to this change. Undoubtedly this was very little to Ulfeldt's taste. Already, in the next year after his release, 1662, he obtained leave to go abroad for his health. But, instead of going to Spaa, as he had pretended, he went to Amsterdam, Bruges, and Paris, where he sought interviews with Louis XIV. and the French ministers; he also placed himself in communication with the Elector of Brandenburg, with a view of raising up enemies against his native country. The Elector gave information to the Danish Government, whilst apparently lending an ear to Ulfeldt's propositions. When a sufficient body of evidence had been collected, it was laid before the High Court of Appeal in Copenhagen, and judgment given in his absence, whereby he was condemned to an ignominious death as a traitor, his property confiscated, his descendants for ever exiled from Denmark, and a large reward offered for his apprehension. The sentence is dated July 24, 1663. Meanwhile Ulfeldt had been staying with his family at Bruges. One day one of his sons, Christian, saw General Fuchs, who had treated his parents so badly at Hammershuus, driving through the city in a carriage; immediately he leaped on to the carriage and killed Fuchs on the spot. Christian Ulfeldt had to fly, but the parents remained in Bruges, where they had many friends.
