Find the town of Mlawa, of which you have already heard. On a front stretching for some twenty-five miles to the north-east of that town, and about a day's march in front of the Prussian frontier railway, the Germans massed two corps, and on 22nd February began to advance in three columns. The right travelled from Mlawa by the railway which you see marked on the map, the centre marched along the main highway towards Przasnysz, and the left followed the valley of a little river towards a road which enters the same town from the north-east. There was only a single Russian brigade in front of Przasnysz, and it was easily driven back. On the 24th the Germans entered the town, in which they seized a number of guns and captured about half the brigade which had been defending it. On the previous day another Russian advanced body which lay on a ridge near the village of Vola, to the south of Przasnysz, had been attacked. Elsewhere the Germans were advancing without much difficulty, but on this ridge a violent battle raged, and the Russians made a most heroic stand. For thirty-six hours they held out, and on the evening of the 24th their reinforcements arrived. Four columns of Russians had advanced on Przasnysz from the Narev line, and the invaders were pressed northward on three sides. They were driven through the town in confusion, and on the 26th it was once more in Russian hands. All the next day the battle raged amongst the snowy ridges to the north-east and north-west of the town, and by Sunday morning the enemy was in full retreat for the frontier, leaving 10,000 prisoners behind him. Thus the whole attempt to capture Warsaw by a flank movement had failed. [Illustration: Scene of the Fighting round Przasnysz.] The Battle of Przasnysz was more like a struggle of the Middle Ages than a modern battle. The Russians short of arms and ammunition, and they could not supply all their trained men with rifles. In this and in other fights the Russians kept unarmed troops in the rear. When the men with rifles fell, the unarmed were sent forward to take up the weapons of the dead and wounded and then fling themselves on the foe. Men rushed into the firing line at Przasnysz with a sword bayonet in one hand and two bombs in the other. They charged through rifle and machine-gun fire until they were near enough to fling their bombs, and then fell furiously upon the enemy with cold steel, utterly reckless of wounds and death. The Germans could not stand against such an onset, and fled. Thus by sheer bodily might the Russians had flung back in rout a foe superior to them in numbers, and once more von Hindenburg found Warsaw beyond his grasp.
