About noon Davout at last arrived on the Russian left, and drove it from its position, while Saint-Hilaire again charged, and the two in combination effected the movement contemplated by the Emperor. In a few hours the Russians, who were receding in fair order and fighting fiercely, began to waver, and some of the formations broke into flight. In this crisis Scharnhorst arrived with five thousand Prussians; he had been compelled to make a long detour in order to avoid Ney, with whom Lestocq had been engaged. By nightfall the French were brought to a stand, and soon after they were driven back from the hamlets which they had seized in their advance. Night ended the fight. Ney had not received his orders until two in the afternoon, and arrived too late for service. The armies retained their relative positions, and both claimed the day. Neither had lost, neither had gained, the field. But the battle was disastrous for both: from first to last the struggle had been desperate and bloody. The losses were virtually equal--about eighteen thousand men on each side. During the evening Napoleon began to arrange a retreat; in fact, Davout was about to begin it when he learned that there was a great commotion in the enemy's bivouac. Advancing as far as possible, the marshal put his ear to the ground and distinctly noted a diminishing rumble, which convinced him that the Russians were withdrawing. This was an agreeable surprise, and Napoleon, when informed of the fact, ordered his army to stand fast. The morning light displayed an abandoned Russian camp. It is impossible to tell which army was in the worse plight; both were in the utmost distress. Augereau had been wounded, and, though not disabled, had left the field. This brought down on him the commander's displeasure, and inasmuch as his corps was nearly annihilated, it was disbanded; some of his regiments were virtually destroyed. The living were gaunt, exhausted, and ill with hunger; an eye-witness declared that but for the arrival, about noon, of some Jewish traders from Warsaw with four tuns of brandy, thousands would have perished from cold and fatigue. The dead were strewn thick over the field, and in some places were piled in heaps. On the white background of a Northern winter the carnage was terribly apparent; the prowlers who skulked from place to place in search of booty could be distinguished in all directions. Marauding began on a frightful scale, discipline was slackened by misery, and for miles around thousands of wretched soldiers stripped the scarcely less wretched peasantry of their few remaining bits of property.
