Thus, in 1597, civil war erupted, and Duke Charles was able to assume control over a large share of the powerful castles in the country, and in this manner achieved control over almost all the Realm. The problem was Finland, where Klaus Fleming's widow guarded Åbo castle. But after psychological warfare, Charles and his followers managed to take the castle in Turku (). It is said that when the Duke entered the castle chapel he saw Klaus Fleming's body lying in a coffin. He is said to have said: "Hadst thou now been alive, thy head would not have been in great safety." Then Fleming's widow Ebba Stenbock is said to have approached the Duke and responded: "If my late husband had been alive, Your Grace would never have entered herein."
