The Russian army, based upon conditions of universal liability to service, can muster in the field for war some 4,000,000 of men. But considering the vast frontiers to be defended, and the great claims therefore made by garrison fortresses, it is not likely that more than 1,500,000 could be mobilised in any one district. It is reasonably possible to imagine a Russian army of a million men being brought to and maintained on the Pacific littoral: of an even greater army based on, say, Harbin. That would be a formidable force, especially if enrolled to fight for the White Races against an Asiatic peril: for then it would share the old military enthusiasm of the Cossacks. There is nothing which will give the inquirer into national characteristics a better key to the Russian than a knowledge of the old Cossack organisation. It was formed, in the days of Russia's making as a nation, from the free spirits of the land, suffering on the one side from Turkish cruelty, on the other from the devastations of the Tartars. "Cossacks" meant simply "free men," and, at the outset, they were freebooters mainly, the Robin Hoods and Hereward the Wakes of Russia. But the patriotic work of resisting the Tartars and the Turks gave them a national aim, and in time they formed a military and religious organisation, unique in the history of European civilisation. From the village Cossacks--irregular volunteer troops, pursuing normally the life of villagers, but ready ever to take up arms against Tartar or Turkish bandits, or to become in turn themselves raiders of the enemy's caravans and villages--sprung up the Cossack Zaporojskoe, garrisoning the "Setch," a great military camp in the heart of the Cossack country. The Cossacks who joined the Setch devoted themselves wholly to military life. They had to swear to complete chastity, to abstinence whilst at war from alcohol, and to obedience to the Greek Church. The Cossack could leave the Setch if he were so inclined, but while he remained within its boundaries discipline was inexorable. In the Setch there was neither organised training, nor compulsory drill, nor military manoeuvres. With the exception of a few elected officers, there were, in time of peace, no social distinctions; but the bravest and the most experienced were treated with respect. For war a Cossack was elected to command each hundred men; his power was absolute. Several hundreds formed a regiment, with a colonel at its head, a temporary officer, elected for one campaign only. The organisation had some artillery and infantry, but its chief strength lay in its cavalry. It also built a Fleet of small boats with which it repeatedly raided the Turkish coast.
