Battle of Køge Bay, 1677
The Swedish Empire lost control of the Baltic to the Danish-Norwegian Union in 1676, during the Scanian War. The following year, they made a push to get control back, and they intended to make the push near the island of Öland. Part of the Swedish fleet jumped the gun, and ran into the Danish-Norwegians in May, resulting in the loss of eight of their twelve ships. Despite this major setback, the Swedes went ahead with their main push in June, and the two fleets made contact on the 30th, with inconclusive baiting maneuvers. On 1 July, 1677, in what became known as the Battle of Køge Bay, the fighting began at 5 am. The Danes baited the Swedes into the shallows, and the Swedish ship Draken ran aground. The Swedes turned about, but this opened a hole in their line, and the Danish-Norwegians used the opportunity to break up the Swedish formation. The Swedes ended up losing another eight ships, while the Danish-Norwegians only suffered light damage. Sweden was unable to regain control of the Baltic for the remainder of the War, which resulted in her troops in eastern Europe getting cut off and forced to surrender, and the repeated looting of her islands and coasts by the Danish-Norwegian fleet.
