The Battle of Bogesund was an important conflict in the campaign of Christian II to gain power over Sweden.

At an early stage, a cannonball ricochetted off the ice, hitting Sten Sture in the leg and killing his horse.

Deprived of their leadership, Sture's forces (mostly armed peasants) fell into disarray and fled.

Sture himself retreated towards Stockholm, but died of his wounds on the ice of lake Mälaren on February 5.

The anti-union resistance was continued by Sture's widow Christina Gyllenstierna and ultimately Gustav Vasa.
