US Presidency
1851

Our statutes declare that if any person shall, within the territory or jurisdiction of the United States, begin or set on foot or provide or prepare the means for any military expedition or enterprise to be carried on from thence against the territory or dominions of any foreign prince or state or of any colony, district, or people with whom the United States are at peace, every person so offending shall be deemed guilty of a high misdemeanor and shall be fined not exceeding $ 3,000 and imprisoned not more than three years: Now, therefore, I have issued this my proclamation, warning all persons who shall connect themselves with any such enterprise or expedition in violation of our laws and national obligations that they will thereby subject themselves to the heavy penalties denounced against such offenses and will forfeit their claim to the protection of this Government or any interference on their behalf, no matter to what extremities they may be reduced in consequence of their illegal conduct.
