The line selected for defence ran almost due north to south from the Vistula up the Bzura and its tributary the Rawka to Rawa and thence across the Pilitza to Opocznow. The territory abandoned was well worth the security gained on this line, and for three weeks the Germans stormed against it in vain. A flank attack from the north of the Vistula was driven back by the Russians at Mlawa, and no better success attended the German frontal onslaughts at Sochaczew, where the main road to Warsaw crosses the Bzura, and at Bolimow, where another crosses the Rawka. The Germans spent their Christmas in the trenches instead of in the Polish capital, thirty-five miles away. Somewhat better fortune was experienced by the Hungarian offensive against the Russians in Galicia, which was part of Hindenburg's plan. Dmitrieff was almost in the suburbs of Cracow at the beginning of December, but his left was then threatened by the Hungarian seizure of the Dukla pass, and he had to retreat to the line of the Dunajec and the Nida with his flank drawn back to Krosno and Jaslo. Presently the Hungarians threatened also the Lupkow and Uszok passes farther east; but reinforcements arrived, Brussilov closed the passes, and Dmitrieff's left swung forward again. It did not, however, advance beyond the Biala, and the Russians spent their Christmas as far from Cracow as the Germans did theirs from Warsaw. Winter, however, brought less respite from war on the frozen plains of Poland than on the sodden soil of Flanders. The first and second attacks upon Warsaw were followed by a third in January; there was a winter battle by the Masurian lakes in February, and a fierce struggle along the Niemen in March; and the Russian offensive across the Carpathians was only stopped by the German spring campaign. The Russians, indeed, were doomed to bear the brunt of the war in 1915, at first with success and afterwards in adversity; for the Germans had reversed the strategy with which they had begun the war. Then they had relied on the defensive in the East while they gathered up all their strength for the crushing of France. That blow having failed, they were now preparing to drive Russia out of the war, while they trusted to their line in the West to hold against any efforts to break it. The change of plan was probably a mistake, though it brought such success at the moment that volatile critics in England were persuaded that the original war on the West had been merely a blind for real designs in the East. At any rate, in the West we had cause to be thankful that the German attacks were but local, and that the serious offensive against Verdun did not come until 1916, when we were prepared to counter it on the Somme.
