On November 8, an incident of the gravest nature occurred, which seemed likely to render futile all the laborious efforts which had been made to keep the peace between England and the United States.
The English mail steamer Trent, one day out from Havannah, was met by the American warship San Jacinto and stopped by a shell fired across her bows. She was then boarded by a party of marines, and the officer in command of the party demanded a list of the passengers. The production of the list having been refused, the officer stated that he knew the Confederate delegates to Europe, Messrs. Mason and Slidell, to be on board, and insisted upon their surrender. Whilst the discussion was in progress, Mr. Slidell made his appearance and disclosed his identity. Thereupon, in defiance of the protests of the captain of the Trent and of the Government mail agent, Mr. Slidell and Mr. Mason, together with their secretaries, were seized and carried off by force to the San Jacinto, and taken as prisoners to New York.
The news arrived in England on November 27, and, naturally, caused the greatest excitement and indignation. It was felt that the limits of concession had been reached, that a stand must now be made if we ever intended to maintain our national rights, and, as a proof that they were in earnest, the Government decided upon the immediate despatch of 8000 men to Canada.
The first private letter from Lord Lyons was written on November 19.
Lord Lyons to Lord Russell.
Washington, Nov. 19, 1861.
I have written so much officially on this unfortunate affair of Mason and Slidell that I have hardly left myself time to thank you for your kind private letter of the 2nd.
I am told confidently that orders were given at Washington which led to the capture on board the Trent, and that they were signed by Mr. Seward without the knowledge of the President. I do not vouch for the truth of this. I am afraid he is not sorry to have a question with us like this, in which it is difficult for France to take a part.
Lord Lyons had made up his mind from the first that, as it was impossible for him to form a correct opinion as to what had actually occurred, the only thing to do was to maintain an attitude of complete reserve. In the absence of authentic information, he felt that on the one hand it would be unsafe to ask for a reparation which might be inadequate; on the other hand he was reluctant to make a demand which might be unnecessarily great. Consequently, he resolved to take no steps until he received instructions from home, refused to say a word on the subject either officially or unofficially, and instructed the Consuls to maintain silence.
