In capturing General Walker and his command after they had landed on the soil of Nicaragua Commodore Paulding has, in my opinion, committed a grave error. It is quite evident, however, from the communications herewith transmitted that this was done from pure and patriotic motives and in the sincere conviction that he was promoting the interest and vindicating the honor of his country. In regard to Nicaragua, she has sustained no injury by the act of Commodore Paulding. This has inured to her benefit and relieved her from a dreaded invasion. She alone would have any right to complain of the violation of her territory, and it is quite certain she will never exercise this right. It unquestionably does not lie in the mouth of her invaders to complain in her name that she has been rescued by Commodore Paulding from their assaults. The error of this gallant officer consists in exceeding his instructions and landing his sailors and marines in Nicaragua, whether with or without her consent, for the purpose of making war upon any military force whatever which he might find in the country, no matter from whence they came. This power certainly did not belong to him. Obedience to law and conformity to instructions are the best and safest guides for all officers, civil and military, and when they transcend these limits and act upon their own personal responsibility evil consequences almost inevitably follow. 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.
