In the middle of the last century, the Swiss publicist Vattel declared, that, on the breaking out of war, we are no longer under obligation to leave the enemy in free enjoyment of his rights; and this principle he applied loosely to the transit of ambassadors.[60] Sir William Scott, afterwards known in the English peerage as Lord Stowell, quoting this authority, at the beginning of the present century, let fall these words:-- “You may stop the ambassador of your enemy on his passage.”[61] And this curt proposition, though in some respects indefinite, has been often since repeated by writers on the Law of Nations. On its face it leaves the question unsettled, whether the emissaries of an unrecognized Government can be stopped. But there is another case in which the same British judge, who has done so much to illustrate International Law, has used language which seems to embrace not only authentic ambassadors, but also pretenders to this character, and all others who are public agents of the enemy. Says this eminent magistrate:-- “It appears to me on _principle_ to be but reasonable, that, whenever it is of sufficient importance to the enemy that _such persons should be sent out on the public service, at the public expense_, it should afford equal ground of forfeiture against the vessel that may be let out for a purpose so intimately connected with the hostile operations.”[62] Admit that the emissaries of an unrecognized Government cannot be recognized as ambassadors, with the liabilities as well as immunities of this character, yet, in the face of these words, it is difficult to see how a Government bowing habitually to the authority of Sir William Scott, and regarding our Rebels as “belligerents,” can assert that a steam packet, conveying emissaries from these belligerents, “sent out on the public service, at the public expense,” was, according to the language of Earl Russell, “pursuing a lawful and innocent voyage.” At least, in this assertion, the British Government seems to turn its back again upon its own history, or it sets aside the facts so openly boasted with regard to the public character of these fugitives.
