Britain in 1790 to arrest the Bounty mutineers. Edwards named it in honour of Francis Reynolds-Moreton, 3rd Baron Ducie, under whom he had served earlier in his career. HMS Pandora turned northwards from Ducie and, because of this change of course, Edwards did not sight the other islands of the group. If HMS Pandora had maintained its course, it would eventually have reached Pitcairn Island and found the Bounty mutineers. The crew of the whaleship Essex, which a whale had attacked and sunk in November 1820, mistakenly believed that they had reached Ducie after a month at sea in two whaleboats. In fact they had reached Henderson Island. Captain Thomas Raine of Surrey, who was searching for the survivors of Essex, in 1820 made the first recorded landing on Ducie. Frederick William Beechey, who arrived in during November 1825, wrote the first comprehensive description of the island. Beechey's expedition did not land in the atoll, but members of the crew sailed around it in small boats. Based on Beechey's survey, the first Admiralty chart of the island was published in 1826. For nearly a hundred years it was the only available map of the island. On 5 June 1881, the mail ship Acadia ran aground on the island while returning from San Francisco, Peru after unloading its cargo. On the way to Queenstown or Falmouth for new orders, Master Stephen George calculated a route passing to the east of Ducie. George left the first mate in command at 6 am. Half an hour later, the first mate saw a white line, which he disregarded on the assumption that it was phosphorescence in the water. Later, realising that it was land, he manoeuvred to avoid running aground, but failed. The look-out excused himself by saying that he thought that the white land was a cloud. The crew made several unsuccessful attempts to re-float the ship, after which the master sailed one of the ship's boats to Pitcairn Island. He was assisted there by the local inhabitants and returned aboard the Edward O'Brien, an American boat, to rescue the rest of the crew. The incident was later investigated in a court in Liverpool, where the ultimate cause of the wreck was left undetermined, though possible causes included a calculation error by the master or an unknown current that carried the ship to the island. The court declared the master not guilty of
