Of the Russian military organization, the strength and weakness have long been known to the world, and the great question for strategists in contemplating the present hostilities was the number of troops which the Northern Power could bring into the field to confront her foe. Various estimates had been given, from the overwhelming army of 400,000 men confidently claimed by Russia's partisans, to a force of little more than a quarter of that strength. But though the actual figures were in doubt, it was possible by collating the information from various sources to arrive at an approximate estimate of the truth.

At the time of the Boxer outbreak in 1900 Russia had 35,000 men in the Far East, and that force was, within little more than a year, trebled. Since the possibility of trouble with Japan had loomed on the horizon, reinforcements had been steadily dribbling over the Trans-Siberian Railway and over seas in the volunteer transports, until the army under the command of the Viceroy of the Far East could not number much less than 150,000 men of all arms, with 286 guns.

Of this force, at least a half must have been absorbed in the defence of the long line of railway communications and in garrisoning fortresses; but the troops available for active operations consisted largely of Russia's most formidable fighting material -- namely, the Cossacks, who possess an endurance and mobility which must be of the utmost value in such a country as that in which the present war was to be fought out.

In the latter part of January, the well-informed correspondent of the London Times at Peking telegraphed his estimate of the Russian forces east of Lake Baikal, which, though a guess, bore the evidence of truth.

According to this authority, Russia had available at that time a total of 3,115 officers, 147,479 men, and 266 guns; and these numbers included the railway guards over the whole of the Manchurian railways and the garrisons of the principal fortresses. The infantry of this force numbered 108,000 officers and men, and the cavalry 22,000 officers and men, of whom nearly the whole were Cossacks. The garrisons of Port Arthur and Vladivostock alone absorbed 45,000 men, and remembering that the railway line to be guarded, east of Lake Baikal, was over 1,500 miles in length, and traverses a country of which the inhabitants were more or less hostile, it is evident that the troops available to take the field at the end of January could not have exceeded, on this estimate, more than 50,000 men.

Lake Baikal is 400 miles in length, and though a railway round its southern extremity was in course of construction, it was far from completion at the outbreak of hostilities. The lake is frozen over during the winter months, when transit has to be effected by sledges. But in the emergency the Russians laid railway lines across the lake, and thus by the end of February had established a through service of sorts. But even then the number of reinforcements and the quantity of supplies that could be moved up to the theatre of war were strictly limited by the delays inseparable from the working of a single track railway, and it is doubtful whether more than 25,000 men at the outside had been added to the field force by the beginning of March.
