The privateer brig Admiral Juel was the second largest ship in Denmark-Norway to be granted letters of marque during the Gunboat War between Denmark and Britain.

The ship-of-the-line HDMS Prinds Christian Frederik and a handful of brigs were (temporarily) safe in Norwegian ports, and the squadrons of gunboats elsewhere on the coast were primarily for defence.

[8][b] In September 1807 the brewer and captain Jens Lind & partners of Copenhagen acquired the brig Christine Henriette, a French-built merchant ship,[3] and presented her to the state for converting and equipping as a privateer of 28 cannon, and a crew of 91.

So early in the season, privateers were not expected and Admiral Juel quickly captured three vessels and brought them back to Copenhagen, where they were greeted with much jubilation.

Capture Sailing in the North Sea Admiral Juel did not find many ships until, off the Yorkshire coast, she encountered two British warships, HMS Sappho and Clio.

When the news of her loss reached Denmark, conspiracy theorists were sure Jörgensen had turned traitor and deliberately sought out British warships in order to surrender his ship.
