Altmark Incident - Background

Background

In February 1940, the German tanker Altmark was returning to Germany with 299 British merchant sailors on board, prisoners of war who had been picked up from ships sunk by the pocket battleship Admiral Graf Spee. On its way from the southern Atlantic to Germany, Altmark passed through Norwegian waters. It was investigated three times on 15 February by the Royal Norwegian Navy. First, the tanker was boarded by officers from the torpedo boat HNoMS Trygg off Linesøy Island, then by officers from the torpedo boat HNoMS Snøgg in the Sognefjord, and finally personally by Admiral Carsten Tank-Nielsen and naval personnel from the destroyer HNoMS Garm in the Hjeltefjord. In each instance, the men who boarded the ship carried out cursory searches and took the Germans' word that the vessel was conducting purely commercial business. Following the third boarding, Altmark was escorted southwards by the torpedo boats HNoMS Skarv and HNoMS Kjell and the guard boat HNoMS Firern. The British prisoners held in the ship's hold reportedly made strenuous efforts to signal their presence, such as shouting loudly and banging on the sides of the hull, to the point where the German crew had to drown out the noise by running winches. However, the Norwegian search parties did not inspect the hold, and allowed the ship to continue on its way.
