Samuel next transferred briefly to H.M.S.Greenwich along with William Daunt who reached the same rank of Midshipman as Samuel. The muster shows their date of entry as 22 September 1781 but the actual date of appearance on the ship was 22 February 1782. It is thought they may have remained on board Confederate during the intervening period to guard the ship until required on Greenwich.

The ship's muster for Greenwich shows both men as being Able Seamen but this was either a clerical error or a temporary rank for this duty. The ship was moored at Longreach, the captain being Will Daniel, the Master Will Smith, the Purser Will Hewett and the Boatswain John Watt.

Both men were discharged from H.M.S.Greenwich on 29 March 1782 then joined H.M.S. Arethusa 'on preferment' on 30 March 1782. Below is information which relates to the time that Samuel was on board, extracted from the ship's muster books which are kept at the Public Record Office at Kew.
