Gustavus was placed for safe keeping in the castle of Eric Bauer, a Jutland noble, where he remained for two years. He lived on the very poorest food, and far worse, had to endure taunts a hundred times more bitter than those of his old school days, from the young nobles about him. Worse still, he learned from them that King Christian was gathering another and greater army with which to utterly crush the rebellious Swedes; and he could neither warn his countrymen nor raise a finger to give them help. But his courage and patience never failed him. Through all that weary time he was always planning and watching for a chance to escape. At last it came. Deceived by his apparent indifference his jailers permitted him to ride, and even to hunt with them, but always under a careful watch. One day, however, the hunt grew so exciting that everyone forgot Gustavus and rode hard and fast after the game. He saw his opportunity, and rode hardest and fastest of all. Soon he was first in the race; but he did not stop when he reached the captured deer. There was no one in sight and he hurried on faster than ever. When his horse gave out he pressed forward on foot, and nightfall found him forty miles from the castle. He astonished a countryman by trading clothes with him; and the next day, thus disguised, he hired himself to a drover to help him drive a herd of cattle to the great German city of Lubeck. Probably no cattle had ever been so driven before. Our hero knew well that the pursuit would be fast and furious, and he kept the herd almost on a steady run. The old drover was in a perpetual state of amazement; he did not know whether to regard his new assistant as a madman or as the most valuable hand he had ever hired. Gustavus never let the poor old fellow rest a moment; he had to eat his meals as he walked, and even to totter along half asleep. At last animals and men reached Lubeck, all badly worn out, but safe, for Lubeck was a free city and a powerful one, and when, an hour later, the enraged Eric Bauer galloped up to its great gates, he knew that his prisoner was beyond his reach, and that unless he could persuade the citizens to give him up there was no chance of recapturing him.
