as General Belgrano of the Argentinian Navy she was stalked for two days by HMS Conquerer, a British Valiant class nuclear sub. On May 2nd 1982 Conquerer recieved orders to neutralise the threat to Britain's Task Force the MM 38 Exocet missile equipped cruiser posed. The sub's captain Commander Christopher Wrexford-Brown, immediately commenced his attack sequence:

"I had a choice of weapon and I chose the older, closer-range, Mark 8 torpedo because it had a bigger warhead and therefore a better chance of penetrating the warship's armour plating and anti-torpedo bulges - good WWII stuff; that isn't in the design of ships these days."

After two hours of working its way into an attack position Conquerer fired three Mark 8's at 18:57Z, at a range of 14K yards. "The object was never to hit with all three but to fire a spread to cover any inaccuracies in the fire control solution."

Two hit and General Belgrano ex USS Phoenix, though heavily modified, sank in freezing miserable seas 250 miles south of the Falklands approx 45mins later with the loss of 368 of her 1,042 crew members.
