The Secretary of State to the British Ambassador (Halifax)

top secret

My Dear Lord Halifax: With reference to your letter of February 6, I would appreciate your transmitting to Mr. Bevin the enclosed reply to the aide-mémoire of January 14 regarding the control of the Great Belt which he handed to me when I was last in London.

Sincerely yours,

James F. Byrnes
[Enclosure]

The Secretary of State to the British Secretary of State for Foreign Affairs (Bevin)

I have given much thought to your aide-mémoire of January 14 suggesting that our two Governments examine the question of the entrances to the Baltic with a view to reaching a policy which might be communicated to the Soviet Government possibly in association with France and the two limitrophe states, Sweden and Denmark.

As I see it, all trading and maritime nations have a general interest in insuring free passage into and out of the Baltic for their merchant [Page 391] ships and war vessels, both in peace and war, and whether neutral or belligerent. To my mind, however, there are really two problems involved which would have to be considered separately: First, that of the Sound and the Belts and, secondly, that of the Kiel Canal.

The multi-lateral and bi-lateral arrangements concluded with Denmark in 1857 establishing the Sound and the Belts as international waterways would seem to cover, from the legal standpoint, the question of free passage through those entrances to the Baltic. In reality, however, as the experience of the last war has shown, freedom of passage through these waterways depends largely on the use of sea and air power by interested belligerent states. You will recall, of course, that as part of her neutrality-defensive measures Sweden mined a part of her territorial waters lying along the Sound. Denmark, under German pressure, did the same in World War I. Nevertheless, I agree with you that at the appropriate time some advantages, both political and otherwise, might be derived from a revision of the 1857 arrangements which would neutralize the Sound and the Belts and would maintain and confirm the right of merchant ships and war vessels of all states, whether neutral or belligerent, to pass freely through them both in peace and war. Appropriate provision would, of course, have to be made for contrary action when directed by the Security Council.

The Kiel Canal, however, raises problems which to my mind are not as readily susceptible of solution in the near future as are the questions of the Sound and the Belts. For one thing, the status to be given to the Kiel Canal is closely related to the regime to be established for all of the European inland waterways.6 But even if consideration of the status of the Kiel Canal should be detached from consideration of the problem of the European inland waterways, it is still, as a waterway lying entirely within Germany, an integral part of the whole problem of Germany’s future status.

We have studied possible solutions of the Kiel Canal problem but have not yet reached a conclusion. We have given a considerable amount of thought to the internationalization of the Kiel Canal by placing it under an international administration, but leaving the sovereignty of the Canal German. The Canal would be opened to navigation by vessels of all states, in time of war as in time of peace, upon the payment of tolls sufficient to cover the administrative costs and upkeep. The affairs of the Canal would be managed by a special international body, on which would be represented all nations chiefly [Page 392] interested in transportation through the Canal. This body, in turn, would be responsible to the Security Council of the United Nations. Certain restricted areas adjacent to the Canal might be usefully internationalized to facilitate the operation of the international administration of the Canal, but no “corridor” would be created. I repeat that we have not reached any final conclusion in our own minds. I should be glad to receive your views on a proposal along the above lines.

I am not so optimistic as is Mr. Lie that the Russians will leave Bornholm when the question of the Kiel Canal and the other entrances to the Baltic has been settled and would prefer, therefore, to put off a definitive solution of both problems involved until the final peace settlements.
