In March 1801, she fought off the British privateer Experiment and the 22-gun warship HMS Arab in a single action.

[4] On 1 September 1800, Lougen came to the rescue of the schooner Den Aarvaagne,[Note 3] when the latter was under attack by the British privateer Dreadnought.

[2] 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 HMS Arab 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.

During the engagement, which lasted for over an hour, one of Lougen's shots struck the Arab's cathead and loosed the bower anchor.
