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.
German torpedo boat Iltis
Iltis was the lead ship of her class of six torpedo boats built for the German Navy (initially called the "Reichsmarine" and then renamed as the "Kriegsmarine" in 1935) during the 1920s. The boat made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, she did not participate in the Norwegian Campaign of 1940 as she was under repair after having accidentally rammed and sunk a U-boat. "Iltis" spent the next couple of years escorting minelayers as they laid minefields and laying minefields herself. She also spent the latter half of 1941 escorting convoys through the Skaggerak. The boat returned to France in 1942 and was one of the escorts for the capital ships sailing from France to Germany through the English Channel in the Channel Dash. "Iltis" then helped to escort one commerce raider through the Channel and was sunk by British forces while escorting another blockade runner in May.
