Thomas Jefferson actually said...
And I do declare and make known that if any person from or within the jurisdictional limits of the United States shall afford any aid to either of the said armed vessels contrary to the prohibition contained in this proclamation, either in repairing such vessel or in furnishing her, her officers or crew, with supplies of any kind or in any manner whatever; or if any pilot shall assist in navigating any of the said armed vessels, unless it be for the purpose of carrying them in the first instance beyond the limits and jurisdiction of the United States, such person or persons shall on conviction suffer all the pains and penalties by the laws provided for such offenses.
