Relates the story of Riou, one of Nelson's captains, whose ship, the Guardian, was badly damaged by an iceberg off the Cape of Good Hope while carrying provisions to N. S. W. The ship appeared doomed and the crew was given permission to leave, but Riou, three officers and a handful of men, including twenty convicts, remained on board. Against all odds they brought her back to the Cape of Good Hope nine weeks later. At Riou's request the twenty convicts were pardoned.
