Operation Tabarin - Reasons For The Expedition

Reasons For The Expedition

There have been several reasons cited for Tabarin. Prior to the start of the war, German aircraft had dropped markers with swastikas across Queen Maud Land in an attempt to create a territorial claim, see New Swabia. In 1943, British personnel from HMS Carnarvon Castle removed Argentine flags from Deception Island. There were also concerns within the Foreign Office about the direction of United States' post-war activity in the region. So the chief reason was to establish solid British claims to various uninhabited islands and parts of Antarctica, reinforced by Argentine sympathies toward Germany.

A suitable cover story was the need to deny use of the area to the enemy. The Kriegsmarine was known to use remote islands as rendezvous points and as shelters for commerce raiders, U-boats and supply ships. Also, in 1941, there existed a fear that Japan might attempt to seize the Falkland Islands, either as a base or to hand them over to Argentina, thus gaining political advantage for the Axis and denying their use to Britain. Deception Island, in the British South Shetland Islands, possessed a sheltered anchorage with an old Norwegian whaling station. In 1941, the British (aboard HMS Queen of Bermuda) had taken the precaution of destroying coal dumps and oil tanks there, to prevent their possible use by the Germans.

It has also been suggested that the operation may have partially been a disinformation exercise, nominally to detect suspected German naval replenishment activity - information which was, in fact, being obtained from the cracking of the Enigma machine.
