"You will certainly be a man in your day, if you live to see it."
He afterwards, thinking of the high descent of the boy and that he might grow to be a future foe of Denmark, asked Sten Sture to let him take the lad to Copenhagen and bring him up in his court. The wise Lord Sten quickly fathomed the king's thoughts and answered that the boy was too young to be taken from his parents. He soon after sent him to his father, then in command at Aland.
"The young wolf has slipped out of my net," said King Hans in later years, when he was told of the splendid development of the boy as he grew to manhood.
At the age of twenty-four he left the academy at Upsala, where he had been educated in the arts and sciences, and repaired to the court of Sten Sture the Younger, where he was soon a general favorite, loved for his amiable character and admired for his wit and vivacity. At that time the war by which Christian II. made himself master of Denmark was going on and young Vasa aided by his courage in winning victory on more than one hard-fought field.
In 1518, during a negotiation between Sten Sture and Christian, then in sore straits in his fleet, the latter agreed to go ashore to confer with the Swedish leader if six gentlemen were sent on board his fleet as hostages. This was done, but before the conference took place a favorable change of wind changed the treacherous king's intention and he sailed off for Denmark with his hostages, all of whom were imprisoned and held to secure the neutrality of their relatives in Sweden.
Among these captives was young Gustavus Vasa, who, thus perfidiously taken, was cruelly confined. Finally, at the request of Herr Erik Baner, a distant relative of the Vasas, the young man was set free, Baner binding himself to pay a heavy penalty in money if he permitted him to escape. Thus it was that Vasa found a new home at Kallö Castle, in Jutland, where his deliverer lived, and where he was well treated and given much freedom.
"I shall not cause you to be strictly guarded nor put you in confinement," said good old Baner. "You shall eat at my table and go where you please, if you faithfully promise not to make your escape or journey anywhere without letting me know."
To this the young man bound himself verbally and by writing, and was given liberty by his generous warder to go where he pleased within six miles of Kallö. At first he was always accompanied by an attendant, but as he won the old man's love and confidence he was suffered to go alone.
But he could not forget the perfidy by which he had been made prisoner, and in 1519, when King Christian was preparing a great expedition against Sweden, the boasts of the young Danish nobles of what they proposed to do chafed his proud soul. Day and night his bitterness of spirit grew, and finally, as the time came for the expedition to set sail, he could bear it no longer but resolved to break his parole and escape to his native land.
It was in the summer of 1579 that he set out, having dressed himself in peasant clothing. Starting in the early morning and avoiding the open roads, he made his way by by-paths, and at noon of the following day reached the town of Flensburg, where he fortunately met some Saxon traders driving a herd of cattle from Jutland to Germany. He joined these, and on September 30 reached the free town of Lübeck. Here the authorities gave him permission to remain, with a warrant for his personal safety while in the town.
