This battle took place on 4 June 1565 between an Allied fleet of 33 Danish and Lübecker ships, under Trolle, and a Swedish fleet of perhaps 49 ships, under Klas Horn. Afterward, the Danes retired to Køge Bay, south of Copenhagen, where Trolle died of his wounds on 25 June. His Second, Jørgen Brahe, died of fever on 28 June.
