Please see ` https://www.hmsnatal.co.uk/index.asp '. In 1940 a man named Bernard Newman published a book: `Secrets of German espionage,' which makes a very interesting read. One small section (pages 213 to 215) is devoted to sabotage of British ships and infers that sabotage may have been responsible for the sinking of five British ships in World War One, while the Germans lost none. The reason why I have focused on HMS Natal is purely because the book raises the interesting point that HMS Natal was armed with ammunition made by the Japanese and bought as an emergency arrangement for that war. At the time the ammuntion was blamed as defective and as a result all remaining stocks were sea-dumped. I am guessing that Japanese versus Russian interests must have led to a surplus of Japanese munitions around the early years of the 20th century after the Russo-Japanese war.
