Under his "Aide Memoire", President Woodrow Wilson officially entered the United States into the Allied Intervention in Russia. In his doctrine, Wilson called on several reasons behind his decision to intervene: to facilitate the safe exit of a stranded Czech Legion from Russia, to safeguard allied military stores located in northern Russia, to put pressure on the Germans with the potential of an eastern front, and to facilitate self-determination with the hope of the creation of a democratic Russia. As Wilsonianism or Wilsonian Idealism was prevalent in Wilson's actions with the Mexican Revolution and the creation of the League of Nations, American intervention consisted of idealistic features as Wilson preferred the creation of a democratic government in Russia. This was seen when American troops, specifically the 339th Infantry Regiment, found themselves in routine engagements with Bolshevik forces in an effort to support Russian revolutionaries.
