The Royal Navy lost several warships to air attacks during the 1982 Malvinas War. One of them, the destroyer HMS Coventry, sank in relatively shallow waters, and London feared that the Soviets might attempt to strip the wreck of highly classified equipment and documents. A bold underwater salvage mission was organised using a team of Royal Navy divers to recover the classified material, initially designated Operation Blackleg. It was a highly risky and dangerous mission carried out under extremely difficult circumstances.
