John was not aboard at the time and so survived, but was forced to cut short and cancel the expedition.On 6 October 1497, John conquers Sweden during a short and effective military campaign, defeating Sten Sture at the Battle of Rotebro after having undermined his position by winning over most of the Swedish nobility.
Sten surrenders to King John in Stockholm and is reconciled with him.
John is crowned King of Sweden, and Sten is given the highest position of authority in Sweden below the King.
