" In the middle of April the Germans took a sombre decision. Ludendorff refers to it with bated breath. Full allowance must be made for the desperate stakes to which the German war leaders were already committed. They were in the mood which had opened unlimited submarine warfare with the certainty of bringing the United States into the war against them. Upon the Western front they had from the beginning used the most terrible means of offence at their disposal. They had employed poison gas on the largest scale and had invented the ‘Flammenwerfer.’ Nevertheless it was with a sense of awe that they turned upon Russia the most grisly of all weapons. They transported Lenin in a sealed truck like a plague bacillus from Switzerland into Russia. Lenin arrived at Petrograd on April 16. Who was this being in whom there resided these dire potentialities? Lenin was to Karl Marx what Omar was to Mahomet. He translated faith into acts. He devised the practical methods by which the Marxian theories could be applied in his own time. He invented the Communist plan of campaign. He issued the orders, he prescribed the watchwords, he gave the signal and he led the attack. "
