laid especially for military purposes. It was along these that we shall witness the German forces rushed from Belgium to drive back the first Russian advance. But, of course, the moment the Germans enter Russian territory they have no advantage over the Russians, since even their wonderful efficiency does not enable them to build railroads as fast as an army can advance. Hence, we observe their efforts to gain possession of the Russian railroads.
We come now to the central part of the eastern front. Here, just below East Prussia, Russian Poland projects into German territory in a great salient, about 200 miles wide and 250 long, resembling a huge bite in shape.
This land is a monotonous, wind-swept plain, slightly undulating, its higher parts not even 500 feet above sea level. To the northward and eastward it descends gradually into the still lower lands of East Prussia and White Russia, but in the south it lifts into the foothills of the Carpathian Mountains.
Gigantic armies are to move over this plateau, timbered in parts with oak, beech, and lime, and in some sections deeply cut by small rivers and streams forming fissures, some narrow and craggy, others broad and sloping with marshy bottoms. Toward the south the soldiers must cross narrow ravines in all directions, often covered with wild, thick undergrowth. The chief river is the Vistula, which enters by the southern boundary and flows first north, then northwest, skirting the plateau region at a height of 700 feet, finally making its exit near Thorn, thence on to the Baltic through East Prussia. Its valley divides the hilly tracts into two parts: Lublin heights in the east and the Sedomierz heights to the westward. Picture in your mind the great armies approaching these ridges, the most notable of which is the Holy Cross Mountains, rising peaks almost 2,000 feet above sea level.
The fighting forces in the northeast, where the plain slopes gradually into the Suwalki Province, must pass over a country dotted with lakes and lagoons, which farther on take on the character of marshes, stagnant ponds, peat bogs, with small streams flowing lazily from one to the other. Here and there are patches of stunted pine forests, with occasional stretches of fertile, cultivated soil. Throughout this section many rivers flow along broad, level valleys, separating into various branches which form many islands and, during the rainy seasons, flood the surrounding country.
Farther west the armies pass through broad valleys or basins, once the beds of great lakes, whose rich, alluvial soil give forth abundant crops of cereals. Here, too, flows the Niemen, 500 miles in length, watering a basin 40,000 square miles in area and separating Poland from Lithuania. It advances northward in a great, winding pathway, between limestone hills covered with loam or amid forests, its banks rising to high eminences in places, past ruined castles built in the Middle Ages. In the yellowish soil along its banks grow rich crops of oats, buckwheat, corn, and some rye. Naturally such a section would be thickly populated, not only on account of the fertile soil, but because the Niemen, like the Vistula, is one of the country's means of communication and transportation. As many as 90,000 men earn their livelihoods in navigating the steamers and freight barges passing up and down this great waterway. At Yurburg the Niemen enters East Prussia on its way to the Baltic.
CHAPTER XLII
THE STRATEGIC VALUE OF RUSSIAN POLAND
It is in the southern part of Russian Poland, among the foothills of the Carpathians, that the armies come into possession of its mineral resources, a fact which will have some influence on the German military movements in this region. Up in the Kielce hills copper has been mined for 400 years, though the value of these mines has decreased on account of the much greater quantity found in America. A hundred years ago the Kielce mines produced nearly 4,000 tons of copper a year. Brown iron ore is also found here in deposits 40 per cent pure, while there are also veins of zinc sometimes 50 feet thick, yielding ore of 25 per cent purity. Sulphur, one of the ingredients for the manufacture of explosives, is found at Czarkowa in the district of Pinczow. In the southwest, in Bedzin and Olkuz, there are coal deposits about 200 square miles in area. In the southern districts wheat is also grown in some abundance.
The military value of this country is further enhanced by political conditions. Like the greater part of Galicia to the southward, it is peopled by the Poles, who form one of the important branches of the great Slavic family. At one time Poland was a kingdom whose territory and possessions spread from the Carpathians up to the Baltic and far into the center of Russia, ruling its subject peoples with quite as much rigor as the Poles have themselves been ruled by Russia and Germany.
Poland is a seat of conquest in the Great War. For not much over a hundred years ago what remained of this old kingdom was divided among the three great powers: Prussia, Austria, and Russia. Austria, on the whole, has been much the best master. Germany tried in various ways to Germanize her subjects in German Poland, thereby rousing their bitter hatred. Russia was no less autocratic in attempting to extinguish the spirit of nationality among the Poles under her rule. But, naturally, the fact remains that between the Poles and the Russians there are still ties of blood. In moving westward, by this route Russia would be moving among a race who, in spite of all they had suffered at the hands of the Czar, still would naturally prefer Slav to Teuton.
We shall soon stand with the invading armies in the center of Russian Poland, and enter the great city of Warsaw. This conquered citadel with more than 400,000 inhabitants, is situated on the Vistula. It was, next to Paris, the most brilliant city of Europe in the early part of last century. But under Russian influence it became a provincial town in spirit, if not in size. It once had the character of prodigal splendor; within late years it became a forlorn, neglected city, not the least effort being made by the Russian authorities to modernize its appearance and improvement. From a sanitary point of view it became one of the least progressive cities of Europe. And yet, as the armies march into the capital, there are still signs of the city's past glory: over thirty palaces rear their lofty turrets above the tile roofs of the houses, among them the palace of the long-dead Polish kings.
However, from a military point of view, Warsaw maintained great importance in the Great War. It is at this time one of the strongest citadels of Europe, and around it lies the group of fortresses called the Polish Triangle. The southern apex is Ivangorod on the Vistula; the eastern, Brest-Litovsk; the northern being Warsaw itself. To the northwest lies the advanced fort of Novo Georgievsk. This triangle is a fortified region with three fronts: two toward Germany and one toward Austria, and the various forts are fully connected by means of railroads.
It would appear, therefore, that Russian Poland would offer excellent conditions for an army on the defensive. And this is quite true, the Vistula, especially, serving as a screen against the attacking armies from the west. As a matter of fact, it would have been extremely difficult to take Warsaw by a frontal attack. Warsaw's weakness lay in the north in the swamp regions.
One of the greatest dangers in all wars, against which a military commander has to guard his army, is that of being flanked. The road or roads leading from the rear to the base of supplies, along which not only food supplies for the soldiers, but, quite as important, ammunition, is brought up, either in wagons, automobiles, or in railroad trains, are the most sensitive part of an army's situation. Unless they are very short—that is, unless an army is very close to its base of supplies—it is impossible to guard these lines of communication adequately. Therefore, if the enemy is able to break through on either side of the front, there is great danger that he may swing his forces around and cut these lines of communication. The army that is thus deprived of its sources of supply has nothing left then but to surrender, sometimes even to inferior forces. Sometimes, of course, if the army is within the walls of a fortified city and is well supplied with food and ammunition, it may hold out and allow itself to be besieged. This may even be worth while, for the sake of diminishing the enemy's strength to the extent of the forces required for besieging, usually many times larger than the besieged force. But in the case of Warsaw we shall see that that would not have been a wise plan; hardly any food supply that could have been laid by would have maintained the large civil population, and the big guns of the Germans would soon have battered down the city's defenses.
This the Russians realized from the very beginning. As is well known now,
