Horn attacked the provinces Halland and Skåne in 1565 and made several attempts at Bohuslän and Uddevalla. The Danish burned old Lödöse in the province of Västergötland. Eric initially led the army against the Danish himself, but then turned over command to Nils Boije, who on 28 August 1564 took Varberg. The Danish army under Daniel Rantzau beat the Swedish army in the Battle of Axtorna on 20 October. The Swedes fared better at sea. Horn, commanding the Swedish navy, pursued a Danish-Lübeck fleet onto the German coast where most of it was destroyed. After this victory Horn steered for Öresund and levied a toll on passing ships. On 4 June 1565, the Battle at Buchow took place on the Mecklenburg coast, in which the Danish-Lübeck commander Herluf Trolle was mortally wounded. In the Battle of 7 July 1565, the Swedish navy under Horn defeated a Danish-Lübeck navy under Otto Rud near Bornholm, where Sweden captured the Danish flagship the Jegermesther. Thus ensured the command of the eastern Baltic by the Swedes that year. In January 1566 Sweden unsuccessfully laid siege to Bohus Fortress in Bohuslän . Daniel Rantzau then moved his forces into Västergötland. At sea Horn returned to taking toll charges in the Baltic. An indecisive battle at sea outside of Öland occurred on 26 July 1566. On 28 July half the Danish-Lübeck Navy was lost in a storm at sea. Horn was then called to command troops on land, where he died 9 September.
