Mr. Phillimore, an English author and an authority on these questions, and one of the judges in the Admiralty, expresses himself thus: "The carrying of official despatches written by official personages on the public affairs of one of the belligerents, impresses a hostile character on those bearing them."
Sir William Scott is no less precise: "The transportation of two or three shiploads of ammunition is necessarily a limited assistance; but, by despatches, the whole plan of the campaign may be transmitted in such a manner as to destroy all the plans of the other belligerent in that part of the world." And he dwells at length on this idea, insisting on the incompatibility which exists between veritable neutrality and the bearing of despatches, "which is an act of the most prejudicial and hostile nature."
Let us also cite Mr. Jenkinson, afterwards Lord Liverpool. He establishes in clear terms the fundamental principle of the matter by putting this question, which plain good sense must answer: "Can it be lawful for you to extend this right (that of the free navigation of neutral vessels) in such a way as to injure me and to serve my enemy?"
Observe that the Queen, in her proclamation of neutrality, has been careful not to omit the interdiction of the transport of despatches. She therein declares that those who transport "officers, soldiers, despatches, arms, ammunition, or any other article considered by law and modern usage as contraband of war, for either of the contenders, will do it at his own risk and peril, and will incur the high displeasure of her Majesty."
Nothing can be more explicit, more consistent, and at the same time more reasonable than these declarations. Sir William Scott is right in saying, that, in undertaking to carry despatches, persons cease to be neutrals and become enemies; this is evident, above all, in the present conflict. As the serious chances of success of the South are all in Europe, as it would not have revolted had it not counted on Europe, as it would lay down its arms to-morrow if it were proved to it that never, for cotton or any thing else, would Europe come to its aid, it follows, thenceforth, that the despatches forwarded from the South to Europe greatly surpass in military importance the sending of soldiers or supplies.
This being so, what ought the commander of the packet Trent to have done? I do not impugn his intentions, he may have acted very innocently; but if this excuse of ignorance of the rules of the law be valid for him, I think that it should also be so for Captain Wilkes, and that there would be little justice in treating with extreme rigor a first offence which evidently has taken every one by surprise, and has found nowhere a very complete understanding of the conditions of the right of search.
The commander of the Trent saw men come to him, whose quality as Southern Commissioners challenged his attention. He knew what anxiety and trouble were pervading the North concerning their mission and despatches, the contents of which excited grave suspicions; there had even been talk, exaggerated, doubtless, of a proposition of a protectorate and other offers, designed to gain at any price the support of one or more maritime powers. The enthusiastic welcome which the people of Havana, enemies of the United States, and ardent friends of slavery, had just given to Messrs. Mason and Slidell, permits no doubt of the especial gravity of the hostile mandate with which they were charged. Then or never was the occasion to say that messengers and messages of this nature must travel under their own flag, and that neutrals were bound not to facilitate their mission in any manner. In circumstances so grave, and with such a responsibility, commanders of packets could not take refuge behind their innocence, or argue that the consul of the United States had not taken pains to forewarn them. I should like to know what reception a neutral would find in England, who should take it into his head to say to her: "I thought myself at liberty to carry hostile despatches and those bearing them, because the English consul did not come to bind me to do nothing of the sort."
Is it true, as has been maintained, that the fault was divided, the message having been carried by one packet and the messengers by another? This appears doubtful, and matters little, moreover, in the eyes of impartial judges. The fact is, that voluminous papers were seized on the Trent, at the same time with the rebel commissioners.
Now, and to have done with the question of right, shall I say a few words of what it is permissible to call the hackneyed rhetoric and declamation of the subject?
Men have talked, of course, of an insult to the flag; they have called to mind that the deck of an English vessel is the same as the soil of the country; they have invoked the rights of British hospitality, and demanded whether she could consent to see her guests taken from her by force. So many phrases for effect, which unhappily never fail to arouse implacable passions! But what is there behind these phrases?
