In the beginning of 1523, Kalmar and Stockholm remained as the only real Danish strongholds in Sweden.

The situation in Kalmar was tense, with many German Landsknechte mercenaries in Danish hire stationed in the city.

When this order became known in the city, the inhabitants quickly made contact with the commanders of the besieging Swedish forces, Arvid Västgöte and Peder Hansson.

An agreement was made that the burghers would leave the northern city gate open on the night before 27 May.

Eight days later Kalmar Castle surrendered as well, and Arvid Västgöte continued on to cleanse Öland of Danish troops.
