Dear Sir: 

REF ID:A70113 • 

2 November 1954 

I wish to express my sincere appreciation for the very kind comments 

you recently made in connection with the Code and Cipher chapter ot my 

draf't MID History covering the peacetime years (1919-1941). They are already proving to be most helpful in my current final revision task. PS&.y 

I ask your further indulgence in order to clear up another point? 

The tollov1ing statement was contained in General Mauborgne's letter of 

comment: 

"I suggest that one or more paragraphs be inserted in the present text 

to cover the fact that I persuaded Secretary Stimson to let the Army send 

one of the .Army-designed Japanese diplomatic code-breaking machines to the 

British High Command in London together with certain experts to demonstrate 

the use thereof", since we feare:id that the Navy was about to send over one 

or these machines and steal Army thunder. Mr. Friedman can give the entire 

story and state just what we got from the British in return -- a most important suap worth recording on the pages of history. 11 

I agree with General Mauborgne that this exchange should be mentioned 

and hope that you may see fit to fill out the gap tor me, including the 

time element. 

Incidently, Lir. Fabyan did publish two books in regard to his Bacon 

decipherment effort. They are presently very difficult to locate but I 

secured both of them through the Department or the Army inter-library loan 

service. I only made full note or one of them,however, as follows: 

George Fabyan, The Ke s for Dec heri the Greate t ~ork ot S

Extract from "History of the Military Intelligence Division, Department 

of the Arurs General Staff," covering the period 1919-1941, preJ&l'ed by 

Col. Bruce w. Bidwell, Infantry, USA* 

Early in July 194o, when it first became apparent that 

President Roosevelt intended to appoint Mr. Stimson to be the new 

Secretary of War, both Brig Gen Sherman Miles, ACofS, G-2, and 

Maj Gen Joseph o. Mauborgne 1 Chief Signal Officer 1 were exceedingly 

apprehensive that this action might cause a serious curtailment 

in the rapidly developing A:rrrry communications intelligence effort. 

General Mauborgne, therefore, proceeded to visit the White House 

in order to discuss this matter with Maj Gen Edwin M. Watson, the 

Military Aide. As a result, it was indicated that the President 

desired the Army to continue with this effort and the War Department received instructions "not to let Secretary Stimson know that 

this was being done." See: Memo, Edward A. Tamm to Director, 

5 Jul 4o, File 62-9798-88, Records of FBI, Washington,, D. c. 

*Sent for review in ltr 23 Aug 54 by Maj Gen A.C. Smith, Chief,,
