The Crisis, Footnote 13
Mr. William Marshall, of this city [Philadelphia], formerly a pilot, who had been taken at sea and carried to England, and got from thence to France, brought over letters from Mr. Deane to America, one of which was directed to "Robert Morris, Esq." Mr. Morris sent it unopened to Congress, and advised Mr. Marshall to deliver the others there, which he did. The letters were of the same purport with those which have been already published under the signature of S. Deane, to which they had frequent reference.
