Hopkins Papers: Telegram
Prime Minister Churchill to the President’s Special Assistant ( Hopkins )1
374. From the Prime Minister to Mr. Harry Hopkins personal.
As you will remember, the President agreed that the exchange of information on Tube Alloys should be resumed and that the enterprise should be considered a joint one to which both countries would contribute their best endeavours.2 I understood that his ruling would be based upon the fact that this weapon may be developed in time for the present war and that it thus falls within the general agreement covering the inter-change of research and invention secrets.
I am very grateful for all your help in getting this question settled so satisfactorily. I am sure that the President’s decision will be to the best advantage of both our countries. We must lose no time in implementing it.
I have asked the Lord President3 to make sure that the right people are on the spot and ready to resume active collaboration as soon as the President has given the necessary instructions. I should be grateful if you would telegraph me as soon as this has been done so that our people can be instructed to proceed to Washington and be at your disposal.
