The ship refused to stop after both flares and warning shots had been fired and Draug had to give chase and capture the vessel.

After leading the unknown ship into Haugesund, its identity was found to be the 7,624 ton German vessel Main.

[2] The two ships left Haugesund at about 0900hrs, but soon came under attack from a Luftwaffe bomber around 40 nautical miles (74 km) off the Norwegian coast.

The bombs, aimed at the Main, missed but the German captain immediately scuttled his vessel and ordered his crew to abandon ship.

[6] He resigned in the same year in protest of Defence Minister Jens Christian Hauge's political priorities, which Horve felt had given the Royal Norwegian Navy an inferior role within NATO (of which Norway was a founding member in 1949).

Horve's work for the war sailors bore fruits in that the Parliament of Norway granted payments to crew in the merchant fleet Nortraship in 1972.
