Quick answers
Where was the Mary Celeste sailing when she was found in 1872?
She was found derelict under sail near the Azores in December 1872 on a New York–Genoa cargo voyage. Gibraltar’s salvage inquiry never proved why the people left.
What was the Mary Celeste?
A brigantine built in 1861 at Spencer’s Island, Nova Scotia, originally named Amazon, later American-owned. In 1872 she carried denatured alcohol from New York toward Genoa under Captain Benjamin Spooner Briggs.
When and where was she found abandoned?
Dei Gratia sighted her on 4–5 December 1872 in the Atlantic east of the Azores. The last log-slate entry was 25 November near Santa Maria. No one was aboard. The small boat was missing.
Who should have been on board?
Ten people: Briggs, his wife Sarah, their daughter Sophia, and seven crew. None was found. No verified landing of the boat was ever recorded.
Did the cargo and ship look plundered?
Most of the 1,701 alcohol barrels were still there; a few were empty or leaking. Personal effects remained. The hull was sailed to Gibraltar. That is not the picture of a stripped prize.
What did the Gibraltar court decide?
The Vice-Admiralty court in 1873 granted salvage to Dei Gratia at a reduced figure and did not find murder, mutiny or a proven cause of abandonment. Attorney-General Solly-Flood’s suspicions were not adopted as a verdict.
The missing were a captain’s family and seven seamen. The living file is the boarding crew and a colonial law officer.
Pirate names from later fiction are not in the 1873 docket.
People
Sarah and Sophia Briggs
Captain’s family
Sarah Elizabeth Briggs and two-year-old Sophia were on the passenger roll. Their presence is one reason later writers rejected a casual mutiny story.
David Morehouse
Master, Dei Gratia
Sighted the derelict and sent a boarding party. Solly-Flood suspected him; the court still paid salvage. He is a finder, not a proven plotter.
Oliver Deveau
First mate, Dei Gratia
Wrote the boarding description the hearing relied on and helped sail Mary Celeste to Gibraltar. His notes are the core eyewitness paper.
Frederick Solly-Flood
Attorney-General, Gibraltar
Pursued crime theories — cuts on the bow, possible foul play — that surveyors and the court did not convert into a finding.
Arthur Conan Doyle
Author of the 1884 story
Not a witness. His Marie Celeste fiction became, for English readers, more vivid than Deveau’s deposition.
Boarders and a law officer left paper. The ten people left a missing boat.
