A friend who's cruising the Indonesian archipelago sent me this clip of the "Raja Laut" which reminded me of it being used in the making of the film "Die Männer der Emden".
SMS Emden was stationed at the German concession of Tsingtao in China (they still make a good German beer there by the same name) when World War I broke out. She was attacked by the Australian cruiser HMAS Sydney in the Cocos Islands and run aground by her captain to prevent her from sinking.
Out of a crew of 376, 133 were killed in the battle. Most of the survivors were taken prisoner, though the landing party, consisting of another two officers, six non-commissioned officers, and thirty-eight sailors, and led by Hellmuth von Mücke, commandeered an old schooner (the "Raja Laut" in the film) and eventually make its way back to Germany.
All real Boys' Own stuff and well worth watching.
