Returning to Denmark in October 1794 Lougen and three smaller ships repatriated 125 troublesome (striking?) house builders to Rostock.[5]
On 1 September 1800, Lougen came to the rescue of the schooner Den Aarvaagne,[8] when the latter was under attack by the British privateer Dreadnought. On Lougens approach, the privateer broke off the action.
Later in 1800, Lougen captured the privateer Eagle and brought the captured schooner into St Thomas.[2]
See main article: article and Battle of West Kay. On 3 March 1801, as rumours of a diplomatic rift between Britain and Second League of Armed Neutrality were first reaching the Danish West Indies, and a full month before the first Battle of Copenhagen, Lougen met and fought with and the privateer Experiment off West Kay, St Thomas. The two British ships approached the brig Lougen, under the command of Captain Carl Wilhelm Jessen, and the schooner Den Aarvaagne. Arab, commanded by Captain John Perkins, approached the two Danish vessels and, according to Danish accounts, without warning, fired several broadsides at Lougen before the Danish ship was able to return fire. Lougen, which had escaped serious damage, began to return fire steadily. Experiment initially attempted to capture Den Aarvaagne, but Den Aarvaagne obeyed orders to stay out of the fight and instead escaped south to Christiansted on St Croix with its intelligence on British actions. Experiment then joined Arab in the attack on Lougen, with the two British ships sandwiching the Danish ship. During the engagement, which lasted for over an hour, one of Lougens shots struck the Arabs cathead and loosed the bower anchor. (Perkins reported that it was the first shot from Lougen that loosed the bower anchor.) Arabs crew was unable to cut the anchor free, leaving Arab unable to manoeuvre effectively. This allowed Jessen to steer a course that brought Lougen under the protection of the shore batteries and then into St Thomas. The Danish government awarded Captain Jessen a presentation sword made of gold, a medal and 400 rixdollars (the equivalent of a whole year's salary for a captain in the Danish Navy) for his actions.[9]
British naval and military activity in the area could not be countered. British forces took Lougen as a prize when they occupied the Danish West Indies in March. One year later, in 1802, the British returned Lougen to Denmark when peace was restored. The Danes later decommissioned the brig and she was broken up.
