Operation Tabarin was a secret mission undertaken by the British that started in 1943 and ended in 1946. Its original purpose was to set up bases in
Graham Land but Lieutenant Commander James Marr with the help of a Discovery Committee decided to extend its reach to surveying and other scientific research. It began with the pretense of searching Antarctica's seas for Nazi
U-boats and other German shipping threats but was actually a cover for the construction of bases in disputed territory
which was claimed by Argentina. Led by
James Marr, who had previous polar experience, the mission team landed at
Port Foster, Deception Island on 6 February 1944 after departing from Avonmouth on 14 December 1943. Halfway through the voyage the expedition force switched ships to the
Fitzroy and
William Scoresby captained by Victor Marchesi. They found no Argentine presence upon landing with the exception of a fuel tank with a painted
Argentine flag. They quickly established camp at an old Norwegian whaling station raising the Union flag and set up Base B as a science station. The rest of the expedition team left for
Hope Bay to set up Base A on 7 February 1944. Due to heavy weather conditions the
Fitzroy and
William Scoresby left on 10 February 1944 and set up camp at Port Lockroy. The two ships departed to the
Falklands after completing the main hut at Port Lockroy on 17 February 1944. The postal office was completed 23 March 1944 after
William Scoresby returned with more crew although it later burned down on 23 April 1944. Survey work began in May not long after the world was alerted of the expedition's existence.
Elke Mackenzie Lamb, a leading scientist in the crew, collected samples of lichen, worms, sea urchins and sponges. In February 1945
Fitzroy, William Scorresby and the Eagle''
arrived at Stations A and B with additional scientists. Once there crew and equipment were loaded on to the Fitzroy
and William Scoresby
and were sent to Hope Bay to construct Station D while others sent to Stonington Island to begin work on Station E were moved out on the Eagle''. Construction of Station E was abandoned after James Marr resigned for health reasons on 7 February. His successor Andrew Taylor shifted focus to Station D at
Seal Point where the base was finished on 20 March 1945. After building a hut on
Coronation Island the British visited Argentina's Meteorology base on Laurie Island. The British began three sledging expeditions to the smaller islands in the area such as Duse Point and
Vortex Island starting in August 1945 and concluding in December 1945 after the team returned to Station D for the final time. The team came back with samples of rocks, lichens, fossils and scientific data and chart improvements. The expedition finished at the start of 1946 when on 14 January 1946 departure of crew began and concluded on 11 February 1946 when all military crew members departed for home. The mission resulted in an expansion of British land claims on the continent and further scientific research. Station A at Port Lockroy is now preserved as a museum. Operation Tabarin was followed by the
Falkland Islands Dependencies Survey. == Secret Nazi bunker ==
