On This Day - What happened 4 April 1982 AD

The nuclear-powered submarine Conqueror set sail from France on 4 April, whilst the two aircraft carriers Invincible and Hermes, in the company of escort vessels, left Portsmouth only a day later.

The Chilean government also allowed the United Kingdom to requisition the refueling vessel RFA Tidepool, which Chile had recently purchased and which had arrived at Arica in Chile on 4 April. The ship left port soon afterwards, bound for Ascention Island through the Panama Canal and stopping at Curacao en route.
