フリッツX
On 23 January 1944 "Janus" was struck by one Fritz X guided bomb dropped by a German He 111 torpedo bomber and sank off the Anzio beachhead in western Italy (according to another version, she was sunk by Henschel Hs 293 glider bomb or a conventional torpedo – see Fritz X article). It took a mere twenty minutes for "Janus" to sink. Of her crew only 80 survived, being rescued by and smaller craft. It was recorded that during her last duty "Janus" had laid down nearly 500 salvos of 4.7-inch shells in the first two days of the landings in support of allied troops.
