On 20 June, the British retook the
South Sandwich Islands and declared hostilities to be over after removing Argentina's
Southern Thule garrison at the
Corbeta Uruguay base. Corbeta Uruguay was established in 1976, but the Argentine base was only contested through diplomatic channels by the UK until 1982. The war lasted 74 days, with 255 British and 649 Argentine soldiers, marines, sailors, and airmen, and three civilian
Falklanders killed. The British Government decreed that all
classified information would be available to the public in the year 2082. However, following the
Freedom of Information Act, a great deal of formerly classified material is now available. The surrender document is on display at the
Imperial War Museum in London. As noted in the museum, the time of surrender was backdated three hours in order that both
Zulu time (UTC) and the local time were recorded as 14 June even though technically it was already 15 June in London, in order to prevent possible confusion by Argentine troops who might have mistakenly thought that they were permitted to keep fighting until the next day, 15 June 1982. Relations between the UK and Argentina were not restored until 1989 and then only under the
umbrella formula which states that the
islands sovereignty dispute will remain aside. Since 1984 in the Falkland Islands, 14 June has been a public holiday called "
Liberation Day". It is marked by a remembrance ceremony in Stanley. ==References==
