6. Capt. John Manley's letter of 16 July (Adams Papers
) was enclosed in Jonathan Williams' letter of 25 July (see note 7). Manley, captain of the privateer Jason
, was captured in Sept. 1779 and was finally exchanged in 1781 (
; Marion and Jack Kaminkow, Mariners of the American Revolution
, Baltimore, 1967, p. 127). Manley recounted his capture and harsh treatment by his captors, including a period in the black hole after an escape attempt, and requested a small sum of money from JA. At the end of the letter, he briefly mentioned Capt. Gustavus Conyngham's arrival at Mill Prison at Plymouth.
