Japanese battleship Ise
On 12 April 1922, while at Yokohama, "Ise" hosted a delegation which included the Prince of Wales (the future King Edward VIII), who was accompanied by his second cousin, the future Lord Mountbatten of Burma. Captain Kanna Norikazu relieved Nagasawa on 1 December. The ship aided survivors of the Great Kantō earthquake in September 1923. From the early 1920s through the late 1930s, "Ise" mostly cruised off the coast of China. Little detailed information is available about her activities during the 1920s, although she helped sink the obsolete destroyer during gunnery training on 10 August 1926. The ship was overhauled in 1928–1929, during which her forward superstructure was enlarged and her aviation facilities improved.
SS Irma (1905)
The first official word to come out about the sinking of "Irma" and "Henry" in Norway was from the Norwegian national socialist party Nasjonal Samling's official publication "Fritt Folk" on 15 February 1944. The national socialist newspaper used the word "Skjendselsdåd" () in the headline. The next day, 16 February, "Fritt Folk" stated that British Motor Torpedo Boats had been responsible for the attack. Only after the end of the Second World War did it become known that the ships responsible belonged to the Royal Norwegian Navy, "MTB 627" sinking "Irma" and "MTB 653" sending "Henry" to the bottom. The two warships had been towed from Shetland to Hustadvika by the converted whaler HNoMS "Molde", departing Shetland on 11 February, and were on a mission to intercept German and German-controlled shipping.
