1. This letter may be considered the last official act by Arthur Lee and JA as members of the joint commission to the French court. Benjamin Franklin's official notification of his appointment as minister plenipotentiary arrived on 12 Feb., presumably after this letter had been drafted and sent (JA, Diary and Autobiography , 2:353). Franklin did not go forward with Pringle's appointment, reverting instead to his plan to name Edward Bancroft as agent. But Bancroft apparently did not go to England either. According to David Hartley, to whom Franklin had written concerning a safe conduct for Bancroft, the British ministry saw no need for an American agent in England to expedite the exchange, In any event, the first shipload of American prisoners reached France on 1 April ( Cal. Franklin Papers, A.P.S. , {p. 406} 2:35; Catherine Prelinger, “Benjamin Franklin and the American Prisoners of War in England during the American Revolution,” WMQ , 3d ser., 32:275–276 [April 1975]).
