The action of 4 April 1941 was a naval engagement fought during the Battle of the Atlantic during the Second World War. A German commerce raider, Thor (Schiff 10 to the Kriegsmarine, Raider E to the British), encountered the British armed merchant cruiser HMS Voltaire and sank her after a short engagement. The German crew rescued the British survivors, some of whom were repatriated and gave an account to the Admiralty. It was accepted that German commerce raiders were too well armed for converted ocean liners equipped with obsolete guns but nothing else was available to the Royal Navy until later in the war.
