OFFICE OF THE COMMANDER-IN-CHIEF
June 7th, 1918
Admiral W.S. Sims,
30 Grosvenor Gardens,
My dear Admiral Sims:
Brigadier General Mason M. Patrick has been appointed as Chief of the Air Service, A.E.F. He will be in London in a few days to take up a number of matters connected with this service, and I have directed him to call on you, and have empowered him to confer with you about the general matter of cooperation between the Army and Navy in the air work to be done by both services.
In my letter to you of May 10, 1918, I expressed my earnest desire that there should be a close understanding between the two services, and that nothing should be left undone to insure the hearty cooperation and unity, which we both desire.
I should be very glad if you will give this matter consideration, and if you will discuss it fully with General Patrick, in order that there may be brought about a thorough working understanding between the two services which we represent in Europe.
With high regard and esteem, I am
John J. Pershing.
