CHAPTER XIV.

WINTER FIGHTING IN POLAND AND EAST PRUSSIA.

In chapter XXIX. of our third volume I told you how von Hindenburg's second attempt on Warsaw was foiled, and how the Russians during the last days of December 1914 stood firm on a front of great strength. At the beginning of the year 1915 the Russian front extended from the Baltic Sea right to the border of Rumania--a distance of at least nine hundred miles. In January 1915 the Russians were holding the longest battle front ever known in the history of the world.

We may divide this very extended battle front as Cæsar divided Gaul--into three parts. The trenches in the central or Polish zone ran from the mouth of the Bzura, on the Middle Vistula, to the Upper Vistula, at its confluence with the Donajetz, in a fairly straight line, for a distance of about two hundred miles. On either side of this central zone there were two wings which differed greatly in character. Both were bent back from the line of the central zone: the north or right wing followed a sickle shape through a region of lake and marsh from the Baltic to the Vistula, and was for the most part within the East Prussian frontier; while the south or left wing ran from the Upper Vistula to follow the line of the Carpathians.

We will now learn something of the fighting which took place in the first three months of the year 1915 on the north or right wing. For the first few weeks there was ordinary trench warfare such as was going on in the West. Attacks and counter-attacks were frequent, but there was no action of any great importance. Most of the attacks were made by night, beneath the light of rockets and star-shells and the glare of searchlights. On the Bzura River the trenches of friend and foe were only sixty yards apart, and in this section of the line the Germans tried a very ingenious method of breaking down the Russian wire entanglements. They filled barrels with clay, and rolled them down the slopes towards the Russians, who believed that men with wire-cutters were hiding behind the barrels and pushing them forward. They therefore flung their hand grenades at the barrels, only to discover that they were moving by their own weight, and that there were no men behind them. When the Russians had thus exhausted their supply of hand grenades, the Germans pushed forward and tried to rush the trenches. They were only beaten off after a furious struggle. Shells and bombs containing poison gases were also used by the Germans on this part of the line.

In Poland there was the same kind of warfare as on the Bzura. Across the plains the Germans had made a maze of very strong trenches and earthworks with deep underground chambers, floored and roofed with wood.

In Galicia, towards the end of January the bright sun melted the snows of the Carpathians, and the streams became roaring torrents which made a very effective barrier against surprise attacks. Nevertheless the enemy kept up a very heavy bombardment across the flooded waters. On the Donajetz River the Austrians broke the rules of war, and fired from their machine guns explosive bullets, which when they entered a man's body blew away half his back.

Towards the end of January the Russians began to take the offensive on the wings. At this time, you must remember, the new forces which the Allies in the West had raised were not yet ready to take the field. The "thin line of steel and valour" in Artois and Flanders was only just holding its own, and it was feared that if the Germans brought troops from the East they would be able to break through the Allied line and reach the Channel ports. The Grand Duke Nicholas was, therefore, requested to attack von Hindenburg, and prevent him from releasing troops for service in the West. Earlier in the war he had sacrificed large numbers of his men in East Prussia to give his Western Allies a breathing space. Now, although his forces were very weak in guns, rifles, and ammunition, he showed the same high courage and chivalry. He knew that, if he pushed forward into the sacred land of East Prussia, von Hindenburg would hasten to engage him, and that if he threatened Hungary, the great granary of the Central Powers, the enemy would be bound to oppose him. The Grand Duke Nicholas was well aware that he could not hope for conquest. All that he could do would be to worry the enemy and prevent him from sending troops to the West.

In order to provide a sufficient force for these attacks, the Russians had to draw off men and guns from their centre. Von Hindenburg knew this, and he therefore determined to make another effort to capture Warsaw by a frontal attack. The fifty-sixth birthday of the Kaiser was drawing near, and what better present could be made to him than the great Polish capital? You will remember that at this time the Russians were lying along the right bank of the Bzura and its tributary the Rawka. Look at the map on the next page and find the town of Bolimov, on the western bank of the Rawka. It is about forty miles from Warsaw, and is connected with it by a fairly good road. In front of Bolimov there are rolling downs and belts of wood. You will notice that the Russian lines cross the Rawka south of Bolimov.

On the last day of January von Mackensen, who had brought up large numbers of heavy guns all along the left bank of the Rawka, began a terrific bombardment of the Russian lines. This was done to puzzle the Russians and make them uncertain as to where the infantry attack was to be made. The Germans proposed to advance on a line of seven miles between Bolimov and the Bzura.

On the night of 1st February, when the snow was falling heavily, the German guns fiercely shelled the Russian trenches between the Warsaw road and the Bzura River. When it was supposed that the wire entanglements had been blown into a million fragments and the trenches utterly wrecked, 140,000 Germans, including Prussian Guards, advanced in masses, sometimes ten and sometimes twenty-two deep. They were mown down by Russian shot and shell; nevertheless they carried the first line of trenches, and by the evening of the 2nd February had pushed the Russians back to the crest of a ridge behind the town of Borzymov. On Wednesday the Germans looked like succeeding; but by means of the railways which you see to the north and to the south of Borzymov, and also by means of the roads, the Grand Duke hurried up reinforcements from Warsaw. They marched through the driving snow, and arrived on the scene of battle late on Thursday. By this time the Germans had been checked. They had pushed across the crest of the ridge behind Borzymov, had advanced five miles along the railway, and had very nearly broken through the Russian front.

The fighting was terribly fierce, and the Germans lost heavily. Around Borzymov the slaughter was so great that the ground was cumbered with German dead, and the survivors used the bodies of their fallen comrades to build up defences. The woods to the south of the Bolimov-Warsaw road were also strewn with dead. By 8th February the Germans had been flung back to the banks of the Rawka, and the Russians had crossed the river at Dachova. The German loss cannot have been less than 20,000 men. The great attempt had failed, and it was now clear that Warsaw could not be captured by a frontal attack.

As soon as von Hindenburg saw that the Bzura-Rawka lines were too strong for him, he was ready with a new plan. He was now about to try a flank attack. Look carefully at the map on the next page and notice the railways which meet in the Polish capital. By these railways alone can a Russian army maintain itself westward of the Vistula. In front of the main railway (A A) from Warsaw to Petrograd you see a river line--that of the Niemen and the Narev. Von Hindenburg's plan was to push out from East Prussia, carry the river line, cut the railway, and thus force the Russians to retire from Warsaw, which would then fall into his hands. Meanwhile the Austrians, on the Russian left wing, were to drive back Brussilov, relieve Przemysl, and try to recapture Lemberg. If these operations should succeed, the Russians would be forced back from the line of the Vistula to the river Bug, and it would take them a year's fighting to recover the lost ground.

First of all we will follow the fortunes of the East Prussian campaign. While the fighting was proceeding on the Rawka, the Russians, who numbered about 120,000, were making headway in East Prussia. Despite the keen frost, the icy winds, and the deep snowdrifts, they pushed back the weak German forces opposed to them, until, on 6th February, their right was not far from Tilsit, and their left rested on the town of Johannisburg. Nowhere were they less than twenty-five miles within the East Prussian frontier.

On 7th February von Hindenburg sprang his surprise upon the invaders. He suddenly hurled 300,000 men against the whole line which the Russians were holding. According to custom, the German left wing made an outflanking movement. It was successful, and the Russians holding this part of the line were forced to retreat along the railway towards Kovno. The 20th Corps just to the south of it now had its right "in the air," and was obliged to retire. In the forests and marshes north of Suwalki it was broken up into parties of stragglers. The remainder of the Russian line was also driven back, but only after a stern struggle. By 15th February the Germans were on Russian soil, and were moving towards the river line which screens the railway from Warsaw to Petrograd. They were about to attack on the Niemen, the Bobr, and the Narev at one and the same time. If the river line should be forced, the railway would soon be reached and cut.

I have told you what happened in East Prussia in a few sentences; but you must not suppose that the Germans won easy victories. The Russians resisted desperately, and many of them fought to the last cartridge. Though their losses were very heavy, they performed a great feat in retreating seventy miles with a force three times as great hard on their heels. The Germans had a good railway system to help them in their East Prussian advance, but more than half of the Russian army had to retire through thick forests and drag heavy guns across a rough, broken country deep in snow and without railways.

The Kaiser sent the following message to his people: "Russians crushingly defeated. Our beloved East Prussia liberated from the enemy. Our beautiful Mazurian land is waste. (Signed) Wilhelm." The Germans claimed that they had captured 75,000 prisoners and 300 guns, but this was false. The total Russian losses were, perhaps, 80 guns and 30,000 men.
