In 1362 the Hanseatic League suffered a total military disaster at Helsingborg, leaving Valdemar IV of Denmark stronger than ever.

[1] In November 1367, 77 members of the Hanseatic diet held in Cologne, decided to form a confederation to attack Denmark.

The war began when King Albert invaded Scania, quickly taking cities like Falsterbo, Ystad, and Lund.

The next day the troops moved to the castle of Lindholmen to reinforce Albert of Sweden, who had been besieging the town since Spring 1368.

[4] The Hanseatic soldiers ended the siege after the attack and withdrew from Lindholmen, as did Albert and the Swedish troops.
