On March 20, 1820, Davis left New Haven, Connecticut for a trip to the Pacific Ocean. He had received news of the discovery of the South Shetland Islands while he was anchored at the Falkland Islands. Learning there were large numbers of seals there, he and another ship captain sailed their vessels to Greenwich Island. But it was too late in the season and other were there before them. So Davis took his ship, named "Cecilia", in search of seals further south. Finding many seals at Low Island he continued southwards. He probably came upon Hughes Bay on the Antarctic Peninsula. His ship's log records he found "a large body of land." He sent a boat to shore to look for seals but found none. He also wrote "I think this southern land to be a continent". He also wrote in the log the latitude was 64°01'S (sixty-four degrees, one minute, south). Davis continued his journey back to Greenwich Island arriving there on 10 February, 1821. He wintered at the Falkland Islands and returned to seal hunting the following season. It remains impossible, however, to prove he was the first to reach Antarctica.
