US Presidency
1870

And I do hereby warn all citizens of the United States and all persons residing or being within their territory or jurisdiction that while the free and full expression of sympathies in public and private is not restricted by the laws of the United States, military forces in aid of either belligerent can not lawfully be originated or organized within their jurisdiction; and that while all persons may lawfully and without restriction, by reason of the aforesaid state of war, manufacture and sell within the United States arms and munitions of war and other articles ordinarily known as contraband of war, yet they can not carry such articles upon the high seas for the use or service of either belligerent, nor can they transport soldiers and officers of either, or attempt to break any blockade which may be lawfully established and maintained during the war, without incurring the risk of hostile capture and the penalties denounced by the law of nations in that behalf.
