"In August 1942, during Operation Pedestal (referenced in Italian sources as Battaglia di Mezzo Agosto) two motosiluranti—MS 16 and MS 22—sank in a night action the British light cruiser HMS Manchester. This 11,000-ton cruiser was the largest warship sank by fast torpedo craft in the Second World War. Two MS boats were used to infiltrate a party of 14 Italian marines behind the Allied lines in Egypt on 3 September 1942. The marines blew up a railway and anaqueduct before being captured."
