The Battle of Jabobshavn (Danish: Søslaget ved Jakobshavn, Dutch: Slag bij maklykoutGreenlandic: Ilulissani qaleruaq eqqaani) also referred to as the Battle of Ilulissat, was a battle between Danish and Dutch ships over the control of Ilulissat (Then Jakobshavn) on 6 June 1739. It has been the only naval battle fought over the rights of Greenland. The battle is sometimes also mentioned as the Battle of Maklykout, referring to the Dutch name of the trading post.
On the other hand, the Dutch claimed the island on the basis of their expeditions and trade companies operating in the area.
Because of the Bergen Company's early failure, Jacob Severin convinced the new King, Christian VI, and his council to grant the company a full monopoly over trade on Greenland in 1734. Severin received the right to fly the Danebrog in order to fend off foreign ships. He also expanded Danish presence on the west coast, establishing the settlements of Christianshaab (1734), Jakobshavn (1741), and Frederikshaab (1742.) This unsatisfied the Dutch whalers in the area, and the opposing sides came in combat at Jakobshavn in 1739.
Battle
A Dutch fortilla of four ships was moored in their habour of Maklykout (Which later got named Jakobshavn in honor of Jakob Severin) outside of Disko Bay. The Dutch had started trading with the local Greenlanders when they were caught by three Danish ships commanded by Jacob Severin. The Danes fired warning shots at the Dutch fortilla, yet the Dutch refused to leave the habour. Severin, in response, attacked the fortilla and the ensuing battle lasted about an hour, during which the Dutch suffered significant damage, before they lowered their flags, surrendered, and conceded their four ships to the Danes. This battle led to the consolidation of Danish presence on the island, and would be the only major naval battle fought over the rights of Greenland.
