There were various frictions, which were mainly due to the psychological pressure of the war and Bolshevik propaganda. The most shocking example was the attitude of French sailors in the port of Sevastopol in April 1919. The crews of the French battleships France, Jean Bart, Verdun, “Justice, and Mirabo rebelled. The sailors joined the Bolshevik workers, raised red flags, and demonstrated in the streets shouting “Long live the Bolsheviks”, “Down with Greece”, “Down with Romania.” The French Major De Villepin ordered the 10th Company of the 2nd Greek Regiment to break up the demonstration. The result was the injury of five French sailors. The French sailors returned to their ships and threatened to bombard the city. The episode ended following the intervention of the British Admiral Calthorpe, who arrived at the port of Sevastopol in time to prevent this revolt from taking on gigantic dimensions.The allied failure in southern Russia was due to a number of factors such, as the lack of machine-guns, transportation problems and difficulties of supply, ignorance of its territory and language, the hostility of the local population, an unfavorable climate, the lack of sufficient forces, the initiative of the Bolsheviks in their operations, and the lack of rest and excessive fatigue, which made it extremely difficult for the Greek soldiers who were fighting far from their homeland. The Greek historian, Constantinos G. Diogos considered the Greek campaign as ‘unheroic’ because it was far outside Greece’s main geostrategic interests.The Greek troops later withdrawn from southern Russia were sent to Smyrna.
