Under these circumstances, when Marshal Rynders presented himself at the State Department on the 29th ultimo with General Walker in custody, the Secretary informed him “that the executive department of the Government did not recognize General Walker as a prisoner, that it had no directions to give concerning him, and that it is only through the action of the judiciary that he could be lawfully held in custody to answer any charges that might be brought against him.”
In thus far disapproving the conduct of Commodore Paulding no inference must be drawn that I am less determined than I have ever been to execute the neutrality laws of the United States. This is my imperative duty, and I shall continue to perform it by all the means which the Constitution and the laws have placed in my power. My opinion of the value and importance of these laws corresponds entirely with that expressed by Mr. Monroe in his message to Congress of December 7, 1819. That wise, prudent, and patriotic statesman says:
It is of the highest importance to our national character and indispensable to the morality of our citizens that all violations of our neutrality should be prevented. No door should be left open for the evasion of our laws, no opportunity afforded to any who may be disposed to take advantage of it to compromit the interest or the honor of the nation.
The crime of setting on foot or providing the means for a military expedition within the United States to make war against a foreign state with which we are at peace is one of an aggravated and dangerous character, and early engaged the attention of Congress. Whether the executive government possesses any, or what, power under the Constitution, independently of Congress, to prevent or punish this and similar offenses against the law of nations was a subject which engaged the attention of our most eminent statesmen in the time of the Administration of General Washington and on the occasion of the French Revolution. The act of Congress of the 5th of June, 1794, fortunately removed all the difficulties on this question which had theretofore existed. The fifth and seventh sections of this act, which relate to the present question, are the same in substance with the sixth and eighth sections of the act of April 20, 1818, and have now been in force for a period more than sixty years.
