A good deal of vague reference has, however, been made in the discussions which have taken place upon the subject to "Treaties" under which it seems to be thought that trading ships enjoy, in all circumstances, rights of free navigation through the Straits in question which they would not have possessed otherwise. I should like, therefore, with your permission, to state what seem to be the relevant Treaty provisions upon the subject, whether between the Powers constituting the European Concert collectively, or between Russia and Turkey as individual Powers.
As to what may be described as the "European" Treaties, it is necessary, once for all, to put aside as irrelevant Art. 10 of the Treaty of Paris of 1856 and its annexed Convention; Art. 2 of the Treaty of London of 1871; and the confirmatory Art. 63 of the Treaty of Berlin of 1878. These articles have exclusive reference to the "ancient rule of the Ottoman Empire," under which, so long as the Porte is at peace, no foreign ships of war are to be admitted into the Straits. There are, however, two articles, still in force, of these "European" Treaties which may seem to bear upon the present inquiry. By Art. 12 of the Treaty of Paris:—
"Free from any impediment, the commerce in the ports and waters of the Black Sea shall be subject only to regulations of health, Customs, [057]and police, framed in a spirit favourable to the development of commercial transactions."
And by Art. 3 of the Treaty of London:—
"The Black Sea remains open, as heretofore, to the mercantile marine of all nations."
It is submitted that these provisions relate solely to commerce carried on by vessels already within the Black Sea, and contain no covenant for an unrestricted right of access to that sea.
As between Russia and Turkey individually, Treaties which are still in force purport, no doubt, to give to the former a stronger claim to free passage through the Straits for her mercantile marine than that which can be supposed to be enjoyed by other Powers. By Art. 7, for instance, of the Treaty of Adrianople of 1829, the Porte recognises and declares the passage of the "Canal de Constantinople," and of the Strait of the Dardanelles, to be entirely free and open to Russian merchant vessels; and goes on to extend the same privilege to the merchant vessels of all Powers at peace with Turkey. Art. 24 of the Treaty of San Stefano is still more explicit, providing that "the Bosporus and Dardanelles shall remain open in time of war as in time of peace to the merchant vessels of neutral States arriving from or bound to Russian ports." The rest of the article contains a promise by the Porte never henceforth to establish a "fictitious blockade, at variance with the spirit of the Declaration of Paris"; meaning thereby such a blockade of ports on the Black Sea as had been enforced by Turkish ships of war stationed at the entrance to the Bosporus.
It may well be doubted whether these articles, containing concessions extorted from Turkey at the end of wars in which she had been defeated, ought not, like so many other provisions of the Treaty of San Stefano, to have been abrogated by the Treaty of Berlin. They are of such a character that, in the struggle for existence, Turkey can hardly be blamed for disregarding them. As was said [058]long ago, "Ius commerciorum aequum est, at hoc acquius, tuendae salutis." The imperious necessities of self-preservation were recognised both by Lord Morley and by Lord Lansdowne in the debate which took place on May 3, although Lord Lansdowne intimated that
"the real question, which will have to be considered sooner or later, is the extent to which a belligerent Power, controlling narrow waters which form a great trade avenue for the commerce of the world, is justified in entirely closing such an avenue in order to facilitate the hostile operations in which the Power finds itself involved."
It is, I think, clear that the solution of a question at once so novel and so delicate must be undertaken, not by any one Power, but by the Concert of Europe, or of the civilised world, which must devise some guarantee for the safety of any littoral Power which would be called upon in the general interest to restrict its measures of self-defence. In the meantime, we may surely say that the case is provided for neither by established international law nor by "European" Treaties; and, further, that the Treaties between Russia and Turkey, which do provide for it, are not such as it is desirable to perpetuate.
