In pursuance of this policy, the laws of the United States do not forbid their citizens to sell to either of the belligerent powers articles contraband of war or take munitions of war or soldiers on board their private ships for transportation; and although in so doing the individual citizen exposes his property or person to some of the hazards of war, his acts do not involve any breach of national neutrality nor of themselves implicate the Government.  Thus, during the progress of the present war in Europe, our citizens have, without national responsibility therefor, sold gunpowder and arms to all buyers, regardless of the destination of those articles.  Our merchantmen have been, and still continue to be, largely employed by Great Britain and by France in transporting troops, provisions, and munitions of war to the principal seat of military operations and in bringing home their sick and wounded soldiers; but such use of our mercantile marine is not interdicted either by the international or by our municipal law, and therefore does not compromit our neutral relations with Russia.

But our municipal law, in accordance with the law of nations, peremptorily forbids not only foreigners, but our own citizens, to fit out within the United States a vessel to commit hostilities against any state with which the United States are at peace, or to increase the force of any foreign armed vessel intended for such hostilities against a friendly state.

Whatever concern may have been felt by either of the belligerent powers lest private armed cruisers or other vessels in the service of one might be fitted out in the ports of this country to depredate on the property of the other, all such fears have proved to be utterly groundless.  Our citizens have been withheld from any such act or purpose by good faith and by respect for the law.

While the laws of the Union are thus peremptory in their prohibition of the equipment or armament of belligerent cruisers in our ports, they provide not less absolutely that no person shall, within the territory or jurisdiction of the United States, enlist or enter himself, or hire or retain another person to enlist or enter himself, or to go beyond the limits or jurisdiction of the United States with intent to be enlisted or entered, in the service of any foreign state, either as a soldier or as a marine or seaman on board of any vessel of war, letter of marque, or privateer.  And these enactments are also in strict conformity with the law of nations, which declares that no state has the right to raise troops for land or sea service in another state without its consent, and that, whether forbidden by the municipal law or not, the very attempt to do it without such consent is an attack on the national sovereignty.
