ON Sunday April 11, 1982, preparations were well under way for a 200-mile exclusion zone to come into force around the Falkland Islands the following day.
The zone was to specify the area where Argentinian ships and aircraft could be engaged by the Royal Navy.
Reports from Argentina suggested the invading troops had laid land mines on the beaches of the Falklands.
Meanwhile, Falklands residents sent a letter to the British Embassy in Montevideo, Uruguay, asking to be evacuated before the British Task Force reached the territory. The letter, signed by the islands’ chief constable and leaders of health, education and housing, was downplayed by senior Falklands officials.
