This battle took place on 31 May 1677 between Femern and Warnemunde, north of modern-day Germany. The Danes had been blockading a Swedish squadron in Göteborg (Gothenburg), and each side had been sending fleets out regularly in the hope of a decisive victory at sea. The Swedish ships, under Sjøblad, left to return to the Baltic and met a larger Danish squadron under Niels Iuel. The action started in the evening of the 31st and continued until the next morning. It was an almost complete Danish victory. Several Swedish ships were captured, most as they tried to flee, and one was run aground and burned.
