With over 300 people aboard his ship, Riou left Spithead on 8 September 1789, and had an uneventful voyage to the Cape of Good Hope where he loaded more livestock and plants. While at the Cape, Riou met Lieutenant William Bligh, who had sailed with Riou on Cook's third voyage during which Bligh had been the sailing master of "Resolution". Bligh had arrived at the Cape from Timor, where he had landed after a 3,618 mile voyage in an open boat following a mutiny aboard his ship, . After completing his re-provisioning, Riou sailed from the Cape in mid-December, and picking up the Westerlies, began the second leg of his voyage to New South Wales. On Christmas Eve, twelve days after his departure from the Cape, a large iceberg was spotted, and Riou decided to use the ice to replenish his stocks of fresh water that were quickly being depleted by the need to supply the plants and animals he was transporting.
