The Ambassador in the United Kingdom (Winant) to the Secretary of State

No. 6107

Sir: I have the honor to transmit copies of two letters with enclosures, addressed to Mr. W. Averell Harriman, by Sir Alexander Cadogan, Permanent Under Secretary of State in the Foreign Office, dated respectively September 9 and October 7, 1942,52 concerning the conclusion between the British and Soviet governments of an agreement for the interchange of information respecting warlike inventions. With the first of these letters Sir Alexander Cadogan enclosed the draft text of such an agreement and mentioned that he would be interested in knowing should the American Government decide at some future date to conclude an agreement of a similar nature with the Soviet Government. In his second letter of October 7, 1942, Sir Alexander Cadogan stated that the British draft had been accepted by the Soviet Government and that notes had been exchanged between the two Governments on September 29, 1942.

There is also enclosed a copy of a memorandum given me by Mr. Harriman explaining the circumstances under which this question developed in the course of his trip to Moscow with the Prime Minister,53 [Page 739] and suggesting the utility of the conclusion of a similar agreement between the United States and Soviet Russia. After talking with Mr. Harriman, I am taking up this question with the Department and both he and I would be grateful for an early indication of the Department’s views and suggestions as to what steps, if any, might appropriately be taken in this matter.

Respectfully yours,

For the Ambassador:
H. Freeman Matthews

Counselor of Embassy

Memorandum by Mr. W. Averell Harriman, Special Representative of President Roosevelt, to the Ambassador in the United Kingdom (Winant)

Last week I gave you Sir Alexander Cadogan’s letters of September 9 and October 7 regarding the British-Soviet agreement to interchange information about warlike inventions and agreed to give you a memorandum on the background.

This subject came up rather informally in one of the meetings in Moscow between the Prime Minister and Stalin in which I participated. The Prime Minister explained to Stalin the reasons for withholding from the Soviet Government information about certain radio inventions. This explanation satisfied Stalin as the Prime Minister had made it clear that this secrecy was in the mutual interest. The Prime Minister said however that all other information on inventions and developments, except for a few cases similar to the one under discussion, would be made available to the Russians if they so desired.

Stalin replied that he would be glad to furnish the British with any of the Soviet developments and specifically offered to show the military members of the party on the following day a new type projectile which he said had proved of great value.

The Prime Minister then suggested to Stalin that these mutual offers might be formalized into an agreement. It was thereupon arranged that Cadogan would meet with Molotov to draft such an agreement.

At this juncture I suggested that the President might well wish to make a similar agreement with the Soviet Government.

It was agreed that Cadogan would advise me of the understanding reached between Molotov and himself and that I would take the matter up with the President. We rather expected that the language would be agreed upon while we were in Moscow and that I would [Page 740] cable to Washington. As you see, however, the discussions have lasted for many weeks and it is only recently that an understanding has been reached.

It seems clear to me that an agreement should be reached promptly between the Government of the United States and the Soviet Government for the following reasons:

(a)
That the information will be of mutual value in the prosecution of the war;
(b)
That such agreement will be another link between the two Governments;
(c)
That as we interchange information freely with the British it would be embarrassing to the British if we did not have a similar agreement with the Russians.
