On this day 40 years ago the HMS Conqueror, a British nuclear submarine, propelled silently through the South Atlantic stalking the Argentinian light cruiser the ARA General Belgrano in the vicinity of the Falkland Islands. At 2.57 pm Conqueror was given the order to torpedo the enemy warship. With two direct hits to the ship, more than 300 Argentine sailors were killed in what remains one of the most controversial actions of the Falklands War.

To mark the 40th anniversary Dan speaks to Vice Admiral Sir Tim McClement who was second in command on the HMS Conquerer about those tense moments as the torpedoes were launched, as well as Will Butler from the National Archives and Naval Historian Iain Ballantyne about the controversy and the information leak that rocked the heart of government.

Iain Ballantyne is Editor of the monthly naval news magazine WARSHIPS International Fleet Review and author of the books 'Hunter Killers' and 'The Deadly Trade' which both feature accounts of how the British submarine HMS Conqueror sank the Argentine cruiser ARA General Belgrano.
