A convict employed on board with a detachment from the galleys had, in fact, at the very first instant, hastened to the officer of the watch, and, in the midst of the consternation and the hesitation of the crew, while all the sailors were trembling and drawing back, he had asked the officer’s permission to risk his life to save the topman; at an affirmative sign from the officer he had broken the chain riveted to his ankle with one blow of a hammer, then he had caught up a rope, and had dashed into the rigging: no one noticed, at the instant, with what ease that chain had been broken; it was only later on that the incident was recalled.
