A Ship That Failed to Arrive
On 4 March 1918, USS Cyclops steamed out of Barbados and turned north towards Baltimore. She was a 542-foot steel collier carrying hundreds of people and a hold filled with dense manganese ore.
Nothing about her departure announced what followed. There was no final scene witnessed from shore, only an expected arrival that never happened. As the days passed, wireless calls went unanswered. Search vessels found nothing they could identify as hers.
The disappearance would later be drawn into the mythology of the Bermuda Triangle, but that label came decades afterwards. The original mystery is starker: somewhere between a known harbour and the American coast, an enormous naval vessel passed beyond the reach of every witness and every surviving record.
