The Mignonette — Starving survivors killed the cabin boy, and the law called it murder

The yacht Mignonette, a small cruising boat being delivered from England to a buyer in Australia, foundered in a gale in the South Atlantic on 5 July 1884, roughly 1,600 nautical miles northwest of the Cape of Good Hope. Her four-man crew — captain Tom Dudley, mate Edwin Stephens, the sailor Edmund Brooks, and the seventeen-year-old cabin boy Richard Parker — escaped into a thirteen-foot lifeboat with almost no provisions: two tins of turnips and no fresh water. They caught a turtle a few days later, but by the third week they were starving and drinking their own urine, and Parker, who had also drunk seawater, lay dying in the bottom of the boat.

On 25 July, after about twenty days adrift and with no sail in sight, Dudley, with the assent of Stephens, cut the boy’s throat with a penknife. The three men drank his blood and ate his body to survive. Brooks took no part in the killing but shared the food. Four days later, on 29 July, the German barque Montezuma sighted the boat and rescued the three living men. They made no secret of what they had done, believing it sanctioned by the seafarers’ grim “custom of the sea” — that starving castaways might draw lots and sacrifice one to save the rest.

The law disagreed. Dudley and Stephens were tried at Exeter and, in the judgment of R v Dudley and Stephens (1884), convicted of murder, the court ruling that necessity is no defence to the deliberate killing of an innocent person. Sentenced to death, they were reprieved by the Crown to six months’ imprisonment. The case did not turn on whether the men were monstrous — the court accepted their suffering — but on whether desperation can license one person to kill another. It remains a cornerstone of the common law on murder and necessity.
