Altmark (ship)

Altmark (ship). The Altmark was a German tanker and supply vessel for the Kriegsmarine, most infamous for its role in the Altmark Incident of February 1940. This event, involving the Royal Navy and the boarding of a neutral vessel in Norwegian waters, became a significant international incident during the early stages of World War II. The ship's service was closely tied to the German cruiser ''Admiral Graf Spee'', for which it served as a dedicated support vessel during its commerce raiding mission in the South Atlantic.

Background and construction

The Altmark was constructed at the Howaldtswerke shipyard in Kiel between 1936 and 1937, entering service in 1938. It was specifically designed as a combined oil tanker and supply ship to support long-range naval operations of the Kriegsmarine. With a significant cargo capacity for fuel and provisions, the vessel was intended to extend the operational range of major warships like pocket battleships. Its construction was part of the broader rearmament efforts under the Nazi regime, led by Adolf Hitler and overseen by Grand Admiral Erich Raeder.

Service as a supply ship

The Altmark is most famously known for its role as the dedicated supply ship for the ''Admiral Graf Spee'' during its commerce raiding campaign in the South Atlantic and Indian Ocean from August to December 1939. Under the command of Captain Heinrich Dau, the Altmark conducted several covert rendezvous with the pocket battleship, transferring fuel, food, and other critical supplies. During these operations, the Altmark also took aboard approximately 300 merchant seamen captured from ships sunk by the Graf Spee, holding them as prisoners of war in its holds. The ship operated under strict radio silence to avoid detection by the British Admiralty and patrolling Allied warships.

Altmark Incident

The Altmark Incident occurred in February 1940, after the Altmark, having separated from the scuttled Graf Spee, attempted to return to Germany via the North Sea. While sailing through Norwegian neutral waters, it was shadowed and then intercepted by the Royal Navy destroyers HMS ''Cossack'', under Captain Philip Vian. Despite protests from the Norwegian Navy, which had previously inspected but not searched the ship, British boarding parties from the Cossack assaulted the Altmark in Jøssingfjord. The action, authorized by First Lord of the Admiralty Winston Churchill, resulted in the liberation of the 299 British prisoners. The incident caused a major diplomatic crisis, severely straining relations between the United Kingdom and Norway, and was used by Germany to justify its later invasion of Norway.

Later service and fate

Following the Altmark Incident, the ship was returned to German control and renamed first Uckermark in 1940, to disassociate it from the notorious event, and later served as a supply tanker for the Kriegsmarine in the Baltic Sea and along the Norwegian coast. It supported various naval operations, including those during the invasion of the Soviet Union. In 1942, while in Japanese-held Yokosuka, the ship was severely damaged by a catastrophic internal explosion, believed to be an accident, and was subsequently repaired. The vessel was ultimately scuttled in 1945 in Kiel as Allied forces advanced, to prevent its capture.

Legacy

The Altmark Incident cemented the ship's place in World War II history, highlighting the contentious issues of neutral rights and international law in wartime. The event was a propaganda victory for the United Kingdom and demonstrated the Royal Navy's willingness to take decisive action. It is frequently studied in the context of naval blockade strategy and the events leading to the German occupation of Norway. The name "Altmark" itself became synonymous with the rescue of prisoners and a bold challenge to Nazi Germany's naval operations.
