The Mary Celeste: which details come from the salvage court, and which from a short story

The Mary Celeste sailed from New York on 7 November 1872, bound for Genoa. Aboard were Captain Benjamin Spooner Briggs, his wife Sarah, their two-year-old daughter Sophia, and a crew of seven. In the hold were 1,701 barrels of industrial alcohol.

A month later she was found sailing alone in the Atlantic, between the Azores and Portugal, with nobody on board. No trace of the ten people has ever been found.

Almost everything the general reader knows about that discovery is fiction, and it is possible to say precisely where the fiction was written.

What the salvage court heard

The Dei Gratia, under Captain David Morehouse, sighted her on 4 December 1872 by the ship's own reckoning. A boarding party led by the mate, Oliver Deveau, went across and gave sworn evidence at Gibraltar a few weeks later.

What Deveau described was a ship in working order and empty of people. The single lifeboat was gone. So were the chronometer, the sextant, the ship's register and the navigation book. There was around three and a half feet of water in the hold — significant, but nowhere near enough to sink her, and one of the pumps had been taken apart.

Some sails were set, some were furled, and some had blown out. A hatch cover was off. Six months of food and water remained. The crew's personal possessions were undisturbed.

The last entry on the ship's log slate was dated 25 November, putting her near the island of Santa Maria in the Azores — several hundred miles behind where she was found.

The court suspected a crime and could not find one

Frederick Solly-Flood, the Attorney General of Gibraltar, ran the salvage hearing on the assumption that the crew of the Dei Gratia had murdered the crew of the Mary Celeste, or that Briggs and Morehouse had conspired to defraud the insurers.

He had marks on the deck and a sword from the captain's cabin analysed for blood. The analysis found none. He examined the ownership and found no shared interest that would support a fraud.

The court awarded salvage in 1873, but at about a fifth of what such a salvage would normally have earned — a judgement that convicted nobody while making the bench's suspicion clear. No charge was ever brought.

Where the famous details were written

In January 1884 The Cornhill Magazine published, anonymously, a short story called "J. Habakuk Jephson's Statement". Its author was a young doctor named Arthur Conan Doyle, four years away from writing Sherlock Holmes.

The story is presented as a survivor's account. It calls the ship the Marie Celeste — Doyle changed the name, though he left the Dei Gratia's name alone — and it supplies the details that are now inseparable from the case: the meal still warm, the tea still steaming, the small domestic scene abandoned in a single instant.

It was written well enough that readers took it for reporting. Solly-Flood himself is said to have responded to it as though it were a factual claim. Within a generation the invented details had migrated into the newspapers, and from there into every retelling since.

What actually appears to have happened

The evidence supports an ordinary and frightening explanation. Alcohol leaking from porous barrels in a hot hold produces vapour. A rumble, a smell, or a hatch blown off would look to a captain like the first moment of an explosion.

The standard response is to get everyone into the boat, stand off on a tow line, and wait to see whether the ship blows up. Briggs took his wife, his daughter, his crew, his instruments and his register — which is exactly the luggage of a man expecting to come back or to have to navigate.

If the line parted in weather, an open boat in the mid-Atlantic in December has no outcome. The ship, unharmed, sails on without them.

One further correction is worth making because it is repeated constantly. The ship is routinely listed among the losses of the Bermuda Triangle. She was found between the Azores and the coast of Portugal, roughly three thousand miles from it.

What can be said with confidence is narrower and more useful. The Mary Celeste is a genuine unsolved abandonment. It is not a ghost ship with a warm dinner on the table, and it never was.
