The attack on Bornholm occurred between 10 to 24 June 1566 during the Northern Seven Years' War when a Swedish fleet of 60 ships under the command of Klas Horn attempted to capture the island. Horn initially sent letters to negotiate but eventually began bombarding the island and later attempted to land, which failed. The Swedes withdrew on 24 June.
