Åbo Bloodbath

Together with other prisoners, including two sons of Finland's previous commander, Clas (Klaus) Fleming, they were tried by a jury speedily assembled from Charles' followers, and sentenced to death.

Fleming's sons and twelve others were then beheaded in Åbo's Town Hall Square, while Stålarm and Kurck were sent to Linköping where they were tried and condemned again along with other captured opposition leaders.

These last strongholds of the opposition, commanded by Arvid Stålarm and Axel Kurck (also Kurk), included Åbo, Helsingfors (Helsinki) and Viborg (Vyborg, Viipuri, Вы́борг), all of which were subsequently taken in the course of Charles' Finnish campaign in the second half of 1599.
