When pirates were executed on a gallows placed between “the ebb and flow of the tide,” the scaffold on which they stood was allowed to fall by releasing the ropes holding it suspended in mid-air. This was always the climax of the spectacle for which thousands of spectators had gathered from far and near. Six pirates were hanged in Boston in 1704 and “when the scaffold was let sink, there was such a Screech of the women” present that the sound was heard over half a mile away. So writes Samuel Sewall, one of the judges who had condemned the pirates to execution.

Not infrequently the judges of a Court of Admiralty had brought before them for trial, a pirate whose career had been more infamous than the rest. A cruel and bloody-minded fellow fit only for a halter,—and then the sentence to be hanged by the neck until dead would be followed by another judgment,—dooming the lifeless body of the pirate to be hanged in chains from a gibbet placed on some island or jutting point near a ship channel, there to hang “a sun drying” as a warning to other sailormen of evil intent. In Boston harbor there were formerly two islands—Bird island and Nix’s Mate—on which pirates were gibbetted. Bird island long since disappeared and ships now anchor where the gibbet formerly stood. Nix’s Mate was of such size that early in the eighteenth century the selectmen of Boston advertised its rental for the pasturage of cattle. Today, every foot of its soil has washed away and the point of a granite monument alone marks the site of the island where formerly a pirate hung in chains beside the swiftly flowing tides.
