Within a week of their return debriefing, the British Secret Intelligence Service and the Foreign Office again sent Reilly and Hill to South Russia under the cover of British trade delegates. Their assignment was to uncover information about the Black Sea coast needed for the Paris Peace Conference of 1919. At that time the region was home to a variety of anti-Bolsheviks. They travelled in the guise of British merchants, with appropriate credentials provided by the Department of Overseas Trade. Over the next six weeks or so Reilly prepared twelve dispatches which reported on various aspects of the situation in South Russia and were delivered personally by Hill to the Foreign Office in London.
