HMS Dunedin
On 24 November 1941 HMS Dunedin was operating out of Freetown, South Africa, engaged in a search for a possible German raider in disguise. Her lookout spotted a mast that suddenly disappeared and she deviated from her course to investigate. He may well have spotted a periscope.
At 1526 hours, two torpedoes from the German submarine U-124 hit her and she sank rapidly. Only four officers and 63 men survived out of the Dunedin’s crew of 486 officers and men.
