The 1940 version of the story told of a distress signal being sent out in an area south of the Solomon Islands. The first received stated "
SOS from the steamship
Ourang Medan. Beg ships with shortwave wireless get touch doctor. Urgent." This was followed by "Probable second officer dead. Other members crew also killed. Disregard medical consultation. SOS urgent assistance warship." After giving her position, the final message received was an incomplete phrase "crew has... ". Vessels responding to the
Ourang Medan received no reply. The 1940 version of the story describes rescue vessels approaching the ship listing in the water, and upon boarding locating multiple crew dead at their posts. As they ventured further into the ship, explosions were reportedly heard and so the rescuers abandoned the ship, and watched it subsequently go ablaze and sink into the Pacific. By 1948, the story was embellished with further details. According to one version of the story, at some point in or around June 1947, two American vessels navigating the
Straits of Malacca, the
City of Baltimore and the
Silver Star, picked up several distress messages from the nearby Dutch merchant ship
Ourang Medan. other sources such as
Vincent Gaddis, list the approximate date as early February 1948.) A
radio operator aboard the troubled vessel is reported to have sent the following message in
Morse code: "S.O.S. from
Ourang Medan * * * We float. All officers including the captain, dead in chartroom and on the bridge. Probably whole of crew dead * * *." After a few more incoherent dots and dashes, the words "I die." were received. No further communications were received. Some versions of the story attribute further details to the sole survivor, an unnamed German, of the
Ourang Medan crew, who swam to safety, and was subsequently found by an Italian missionary and natives on
Taongi Atoll in the Marshall Islands. The man, before perishing, tells the missionary that the ship was carrying a badly stowed cargo of
oil of vitriol, and that most of the crew perished because of the poisonous fumes escaping from broken containers. According to the story, the
Ourang Medan was sailing from an unnamed small Chinese port to
Costa Rica, and deliberately avoided the authorities. ==Hypotheses==
