Macna's Mana and the Kremlin

In the early summer of 19 18, mana embarked on a tour of russia to jin up support for the ukranian resistance. While in moscow he had two important meetings. First with an aging kripotkin, who offered him sage advice and cautious encouragement. But the other was an audience with lenin in the kremlin. There is apparently no other contemporaneous calendar entry or note from anyone working inside the kremlin at the time that confirms this meeting ever took place.
