[2] President Wilson allowed Lansing and Frank Polk quietly and informally to channel the flow of military and law enforcement material into the State Department's Bureau of Secret Intelligence (U-1).
The two men picked a young clerk named Leland Harrison "to take charge of the collection and examination of all information of a secret nature coming into the Department from various sources and also to direct the work of the agents specially employed for that purpose.
[3] In proposing this to President Wilson, Lansing contended that given the serious diplomatic consequences involved with both the act and the investigation, the Department of State should oversee the response and actions of other agencies.
"[5]Where this became significant was that prior to American entry in the war, Lansing had acted as the leader of a virtual shadow government within the Wilson administration, a secretive cabal that quietly maneuvered for intervention on the side of the Entente.
In hopes of uncovering evidence of German treachery that would make the argument for intervention irresistible, the bureau's special agents spied on diplomats and businessmen from the Central Powers residing in the United States, an activity that obviously undercut Wilson's public vow of impartiality and would have infuriated other branches of government had they been told.
Instead, Lansing had used State Department discretionary funds to create the bureau, enabling it to operate without the approval or even the knowledge of Congress or most of the rest of Wilson's cabinet.
Pulling Leland Harrison from the Latin American division, Lansing had placed his young protégé in charge of this "extra-legal" new office, tasked to overseeing "the collection and examination of all information of a secret nature."
From his base in Cairo, Yale would send weekly dispatches through the American embassy's diplomatic pouch to Washington, where they would be routed exclusively to Harrison's attention.
En route to Cairo, he was to stop off in London and Paris to take a sounding of those British and French officials most directly involved with Middle Eastern affairs.
As Harrison cabled to the American ambassador in London: "[Yale] is to keep us informed of the Near Eastern situation and, should the occasion arise, may be sent on trips for special investigation work.
An exemplar of the American can-do spirit, William Yale also held to the belief, quite common among his countrymen, that ignorance and lack of experience could actually bestow an advantage, might serve as the wellspring for "originality and boldness."
