The hostilities with Denmark recommenced. King Christian appeared with a fleet and an army, in June, 1518, laying siege to Stockholm. His attacks were valiantly repulsed, and Christian, fearing to be encircled by his enemies, marched away in a southeasterly direction, taking a firm position at Brennkyrka. A Swedish army met him from the south and gave battle one of the last days of July, 1518. It was a fierce conflict, ending with a victory for the Swedes. The chief banner was carried by the squire Gustavus Ericsson Vasa, who five years later was to become king of Sweden. Christian returned to attack Stockholm, once more in vain. He was to sail for Denmark, but was kept back by storms, great suffering being experienced by his men. Christian was forced to open deliberations, making very high demands. But Lord Sten refused to hold a meeting, postponing it to the following year. A few days later, King Christian sent word that he wanted the regent to visit him in his ship on important affairs. Lord Sten, always good-natured and ready to accept peace, thought that the king had changed his mind and was ready to go. But the burgomaster and council of Stockholm prevailed upon him not to go, sure that it would bring him into the enemy’s hands. Lord Sten took their advice and arranged for a meeting on land, sending six Swedish nobles as hostages to the king at his demand. Among these were Dr. Hemming Gad and Gustavus Ericsson Vasa. For two days Lord Sten waited in vain for the king to appear. Then he learned, to his dismay and indignation, that King Christian had sailed to Denmark, taking the hostages with him as prisoners, October 4, 1518.
