The Minister in Sweden (Johnson) to the Commanding General, Manhattan Engineer District (Groves)
My Dear General Groves: I received your Top Secret letter of July 6 in London on July 14 from Major Harry S. Traynor. I now enclose the original copy in English of a note to me from Mr. Östen Undén, Swedish Minister for Foreign Affairs, and signed by him. The contents of this note are self-explanatory. A copy was handed by the Foreign Minister to the British Minister and has, I understand, been transmitted by him to London.
Mr. Undén gave, on behalf of his Government, the oral assurance that until the legislation contemplated by the note has become effective, which will put control of uranium-bearing materials completely in the hands of the Government, that the Swedish Government will, through the machinery of existing law, control and prevent the exportation of any uranium-bearing materials. The Government will simply refuse to issue any licenses for export of this material. I understand that the legislation is to be introduced into Parliament early in October and within a month or six weeks thereafter should be in full effect. I requested Mr. Undén also to agree that if any request, formal or informal, by any foreign Power to obtain use of or control of uranium-bearing materials in Sweden should be presented to his Government, that the United States and Great Britain would be immediately informed. Mr. Undén said that he personally was willing to give such an assurance but that he would have to consult with the Prime Minister and certain other colleagues in the Government and get their approval. On September 13 he sent for me and stated that he was authorized to give a formal oral assurance that the United States and Great Britain would be informed immediately of any request by any foreign Power to obtain use of or control of uranium-bearing materials in Sweden, which request might be of a “serious” nature. He explained the expression “serious” by saying that if an ordinary commercial request should be made for supplies of this material, for instance as a coloring agent in the manufacturing [Page 46] of pottery glazes, it would not be considered a “serious” request. In any event, whether the request should be “serious” or not, exportation would be prohibited by the proposed legislation, and in the meantime licenses for export for any purpose would be refused by the Government.
It is my considered opinion that the obligations undertaken by the Swedish Government in the solemn declaration which is embodied in this note fully achieve our essential purposes. The requests we made in the original draft for exploitation and exclusive export rights to this material were in my opinion impracticable from the Swedish point of view and unobtainable under present world conditions.
I would like to express to you the appreciation I feel for the very able and invaluable services of Colonel Lansdale and Major Vance in the negotiation of this agreement. Colonel Lansdale will fill in this report to you orally when he returns to Washington. He and Major Vance kept a daily record of our progress and that, I believe, is already in your hands.
I should add that no papers in connection with this matter are being kept in the files of this Legation. All those papers which Colonel Lansdale and I considered important are being returned to Washington and the others are being burnt. There is only one English copy of the agreement in the secret files of the Swedish Government, together with one copy of a Swedish translation.
I am likewise enclosing a Swedish translation furnished by the Foreign Office of the English note.
Sincerely yours,
