The Battle of Møn, also known as the Battle of Fehmarn, took place 31 May–1 June 1677, as part of the Scanian War. A smaller Swedish squadron under Admiral Erik Sjöblad attempted to sail from Gothenburg to join the main Swedish fleet in the Baltic Sea. It was intercepted by a superior Danish-Norwegian force under Niels Juel and decimated over the course of two days. The Swedes lost 8 ships and over 1,500 men dead, injured or captured, including Admiral Sjöblad himself, while the Danish losses were insignificant. The victory prevented the Swedish navy from concentrating its forces and provided valuable prize ships for the Danish navy. It confirmed Danish supremacy at sea during the war and laid the ground for the major Danish-Norwegiam victory at Køge Bay 1–2 July that same year. Prelude Henrik Horn was appointed commander-in-chief of the Swedish navy in March 1677, becoming the third consecutive navy chief (after Gustaf Otto Stenbock and Lorentz Creutz) without any naval experience. The Danish fleet, on the other hand, was well-staffed with capable, experienced officers, which placed the Swedes at a marked disadvantage from the outset. Horn was quickly informed that Dutch reinforcements under Tromp were heading for the Baltic, and on 21 April he was received orders from King Charles to join the main body of the Swedish fleet with a minor squadron anchored off Gothenburg under the command of Erik Sjöblad. The main fleet did not get to sea until early June, but Sjöblad nevertheless sailed as early as 20 May to join Horn. Sjöblad tried to sail through the Great Belt, but was becalmed for on the 23rd and did not pass Langeland until the 29th. Danish admiral Niels Juel, victor of the battles of Bornholm and Öland in 1676 was already at sea with 13 large warships, a yacht and two fireships when he received the report on Sjöblad's position on 28 May; within two days, the two fleets had sighted one another. The Danish force was superior in numbers, armament and quality of equipment. Sjöblad's force had nine ships to Juel's 13, eight of which had 50 or more guns. The Danish ships were also dedicated warships while the Swedish vessels were armed merchants and less suited for battle. In total, the Swedes had 394 guns while the Danes had nearly 670, and the heaviest guns on the Swedish sides were merely 12-pounders, a
