Zealand War

The Zealand War is a war between Sweden and Denmark over Sjalland and other Danish provinces.

Background
Norway gained provinces in Jutland following the Jutland War, but were unable to actually get there except by sea. Charles II said that this was his main goal, but that he also wanted to control the trade around Lubeck more.

The War
Charles II declared war on Denmark on 8 November 1587. While the Swedish navy was supposed to be in the Oresund to allow Swedish troops to invade, the sailors were fearful of losing so many ships again. Fortunately, Lubeck allowed Swedish troops to pass through, and a detachment already in Pomerania quickly moved to attack Kolding. English ships blockaded the western Danish coast, and the Swedish navy finally took control of the Oresund. The Swedish forces in Skane attacked Sjalland after the navy took control of the strait.

Pomeranian forces besieged Kolberg and other forces attacked the rest of Pomerania. However, English troops landed in Schleswig in 1588, and morale quickly dropped. Kolding fell to Sweden on 4 July, and Sjalland shortly after on 30 September.

End
Charles II underestimated the Danish military technology, and thus wished to end the war as fast as possible. On 27 January 1589, the Treaty of Marstrand was signed, which ceded Sjalland, Fyn, and Kolding to Sweden. He immediately granted these lands to Norway. A small amount of money was also paid to Sweden.
