  ## Loss
  
  On 30 October 1779, Tortoise, Captain John Frodsham, was sailing from Saint Kitts to England in company with a number of other vessels. She was leaky, and as the crew was becoming exhausted from manning the pumps, Frodsham ordered signals of distress. Her crew heaved guns overboard and cut her masts away, but she was salvageable. By 4 November the weather had moderated sufficiently to permit the crew to abandon her to founder. A brig that had stood by rescued the crew.
