The climax in this suicidal war came on the 26th of May, when the whole Russian army, led by General Diebitsch, advanced upon the Poles. During the preceding night the Polish army had retreated across the river Narew, but, by some unexplained error, had left Lubienski's corps behind. On this gallant corps, drawn up in front of the town of Ostrolenka, the host of Russians fell. Flanked by the Cossacks, who spread out in clouds of horsemen on each wing, the cavalry retreated through the town, followed by the infantry, the 4th regiment of the line, which formed the rear-guard, fighting step by step as it slowly fell back.
Across the bridges poured the retreating Poles. The Russians followed the rear-guard hotly into the town. Soon the houses were in flames. Disorder reigned in the streets. The fight continued in the midst of the conflagration. Russian infantry took possession of the houses adjoining the river and fired on the retreating mass. Artillery corps rushed to the river bank and planted their batteries to sweep the bridges. All the avenues of escape were choked by the columns of the invading force.
The 4th regiment, which had been left alone in the town, was in imminent peril of capture, but at this moment of danger it displayed an indomitable spirit. With closed ranks it charged with the bayonet on the crowded mass before it, rent a crimson avenue through its midst, and cleared a passage to the bridges over heaps of the dead. Over the quaking timbers rushed the gallant Poles, followed closely by the Russian grenadiers. The Polish cannon swept the bridge, but the gunners were picked off by sharp-shooters and stretched in death beside their guns. On the curving left bank eighty Russian cannon were planted, whose fire protected the crossing troops.
Meanwhile the bulk of the Polish army lay unsuspecting in its camp. Skrzynecki, the commander, resting easy in the belief that all his men were across, heard the distant firing with unconcern. Suddenly the imminence of the peril was brought to his attention. Rushing from his tent, and springing upon his horse, he galloped madly through the ranks, shouting wildly, as he passed from column to column, "Ho! Rybinski! Ho! Malachowski! Forward! forward, all!"
The troops sprang to their feet; the forming battalions rushed forward in disorder; from end to end of the line rushed the generalissimo, the other officers hurrying to his aid. Charge after charge was made on the Russians who had crossed the stream. As if driven by frenzy, the Poles fell on their foes with swords and pikes. Singing the Warsaw hymn, the officers rushed to the front. The lancers charged boldly, but their horses sank in the marshy soil, and they fell helpless before the Russian fire.
The day passed; night fell; the field of battle was strewn thick with the dead and dying. Only a part of the Russian army had succeeded in crossing. Skrzynecki held the field, but he had lost seven thousand men. The Russians, of whom more than ten thousand had fallen, recrossed the river during the night. But they commanded the passage of the stream, and the Polish commander gave orders for a retreat on Warsaw, sadly repeating, as he entered his carriage, Kosciusko's famous words, "Finis Poloniæ."
The end indeed was approaching. The resources of Poland were limited, those of Russia were immense. New armies trebly replaced all Russian losses. Field-Marshal Paskievitch, the new commander, at the head of new forces, determined to cross the Vistula and assail Warsaw on the left bank of the stream, instead of attacking its suburb of Praga and seeking to force a passage across the river at that point, as on former occasions.
The march of the Russians was a difficult and dangerous one. Heavy rains had made the roads almost impassable, while streams everywhere intersected the country. To transport a heavy park of artillery and the immense supply and baggage train for an army of seventy thousand men, through such a country, was an almost impossible task, particularly in view of the fact that the cholera pursued it on its march, and the sick and dying proved an almost fatal encumbrance.
Had it been attacked under such circumstances by the Polish army, it might have been annihilated. But Skrzynecki remained immovable, although his troops cried hotly for "battle! battle!" whenever he appeared. The favorable moment was lost. The Russians crossed the Vistula on floating bridges, and marched in compact array upon the Polish capital.
And now clamor broke out everywhere. Riots in Warsaw proclaimed the popular discontent. A dictator was appointed, and preparations to defend the city to the last extremity were made. But at the last moment twenty thousand men were sent out to collect supplies for the threatened city, leaving only thirty-five thousand for its defence. The Russians, meanwhile, had been reinforced by thirty thousand men, making their army one hundred and twenty thousand strong, while in cannon they outnumbered the Poles three to one.
