However, the pro-Danish Riksråd had elected Erik Trolle as Rikspreneur in January but was forced to withdraw that decision because Sten Sture the Younger than already had the common people on his side and controlled the most important strongholds.

[3] The Danes grew tired of the Swedes' procrastination and in the spring of 1516 began preparing armor for an attack.

[3] This had secured the loyalty of the bailiffs in his father's largest fataburslän Stockholm, Turku, Västerås and Borgholm and tried to confiscate the collected tax.

[4] The election of the head of state was postponed until after the peace negotiations with Denmark, in exchange for the board being left to a council committee and for Sten Sture to waive the tax.

It was on this occasion that the bishop of Linköping, Hans Brask, put a note under his seal, the so-called brasklapen.

[6] After the deposition as archbishop, Gustav Trolle obtained a papal bull against Sten Sture and the bishop of Roskilde excommunicated him, after persuasion by Christian II.

They set up a camp on Brunkebergsåsen, but later moved to Södermalm, where it was easier to defend themselves, but where they could also bombard Stockholm with cannons.

Two Danish storming attempts were repulsed, after which Sten Sture decided to attack Christian II's troops from the south.

After six weeks, food shortages caused Christian II to set sail to obtain provisions, but during their attempts to stock up they were attacked by Sten Sture's forces.

No conversation took place and the Danes set sail in early October with the Swedish hostage on board.

During the summer, battles took place in southern Sweden, among other things Sören Norby attacked Öland and captured Borgholm Castle.

When news of the Danish attack reached Sten Sture, he marched towards Västergötland, where a defense of Bogesund on lake Åsunden was being prepared.
