United States Ambassador to Great Britain Walter Hines Page to Secretary of State Robert M. Lansing
Dated June 13, 1917,
Rec’d 8:00 p.m.
Secretary of State,
6457, June 13, 9 p.m.
Your 4955, June 8, 4 p.m.
Strictly Confidential. I had principally in mind the following referring to your instructions: Cusachs who accompanied Captain Decker to Spain via England and about whom the British secret service knew before he left American although Decker tried to conceal the fact that Cusachs was traveling with him and the reasons for Cusachs proceeding to Spain. This called forth Admiral Sims’ telegram to the Secretary of the Navy My 3331, June 1, 8 p.m. Also Judson see Dell’s telegram to Harrison 6338, June 2, 11 a.m. who indirectly approached British Admiralty with a request to facilitate his journey from France to Holland via England.
Sims agreed with me that if confusion and serious difficulties are to be avoided most complete cooperation should exist between our secret service if any in neutral European countries and services of the Allies who are extremely efficient and have the ground well covered. It is in the highest degree important that officer be assigned to cooperate with British secret service here.
