On 8 November 1942 Argentina laid claim to Antarctic land when an expedition under the command of the captain Alberto J. Oddera placed a cylinder containing a report and a flag on Deception Island. In January 1943 the British ship HMS Carnarvon Castle crew destroyed the evidence of the Argentine inauguration and planted the British flag. On 5 March of the same year the Argentine vessel ARA 1° de Mayo removed the British flag.
