Unfortunately for Christian, though he could repeat Sigbrit's sayings, and perhaps also in a measure recognize their wisdom, he had not the natural capacity to carry them into execution. This clever woman recognized that the aim of the king should be to reinstate the Scandinavian Union, to break the power of the aristocracy and the clergy, and to free his impoverished people from the fetters in which the Hansa had bound them for nine centuries. This was all right and well, but it needed to be carried into effect with tact and moderation. Christian did not possess these gifts; he made himself personally detested by his cruelty and his overbearing manner, he knew not that generosity which so gracefully becomes a victor. After conquering Sweden, he soiled his victory by causing the most illustrious personages of the kingdom to be executed, and still worse he stained his personal honour by violating the conditions of an armistice in causing Gustavus Ericson, of the house of Vasa, to be carried off captive to Denmark. It did not improve matters when Christian explained that he required him as a hostage. He caused Gustavus to be shut up in the strong fortress of Kalo in Jutland. Here the captive was put on his parole, and it is said suffered none of the rigours of custody. But the food put before him, salt junk, sour ale, black bread, and rancid herrings, cannot have comforted his enforced captivity in the material sense, while he confessed to having been maddened by the talk of the soldiers who guarded him, and who boasted that they would soon hold all Sweden, and jestingly parcelled out among themselves the wealth and beauty of the nation. This young man so unjustly imprisoned was destined to become the avenger of his fatherland, and those of his fellow-countrymen who had perished upon the scaffold. He resolved to escape, hoping to reach Sweden in time to defend his country, or to take advantage of any favourable juncture that might arise. It was in September, 1519, that, early one raw autumn morning, Gustavus managed to escape from the Castle of Kalo, disguised as a drover of oxen. He made his way to the city of Lübeck, and threw himself upon the protection of the burgomaster and council. Needless to say the town gave a generous welcome to the man who was foe of their foe--the King of Denmark. But it was not long ere his whereabouts became known, and Christian sent messengers to Lübeck, demanding in high-handed language that Gustavus should be handed over to him. He complained that Vasa had effected his escape contrary to his pledged word as a knight. Gustavus spoke in his own defence.
