The morning after this indecisive battle the entire Russian army was far away. For strategic reasons and for lack of provisions it had withdrawn to Ostrolenka. There was no pursuit. The natural question, Why? is still unanswered. Some declare that the French troops were too weary and bad-tempered; others, that Napoleon, in view of the quagmires to which the roads were now reduced, dared not abandon his base of supplies, as he was accustomed to do in summer weather and in fruitful lands. There is still a third answer, that nothing was to be gained; for of what use were the few miles of bare, flat land which the army, putting forth its utmost exertions, might have been able to traverse? All these reasons have validity. There was discontent among the soldiers, for there was no booty; not even a soldier's common comforts could be found. For the first time men of the line shouted insults after the Emperor, and with impunity; even the faithful guard indulged in double-meaning quips, but they, on the other hand, were at the proper time soundly berated. "The short campaign of fifteen days," wrote one of them, "made us ten years older." There was also danger in advancing beyond reach of the commissary department,--deficient and contemptible as it was in the hands of unscrupulous speculators,--and there was indeed little to be gained by such a pursuit as was possible, except prestige, which at that moment and at that distance from France was not a valuable commodity. This element of distance from home was weighty. In far-off Egypt and Syria, French soldiers had fought bravely; an ideal will carry even the commonest Frenchman far, and they then believed themselves to be fighting for a principle. But since the armies of France had begun to fight for booty and glory, they must have both. Of the former there was little or none at all in the lands they now occupied; the latter could be enjoyed only in the jubilations of their kinsfolk; and although no account of any battle was more beclouded than that of Pultusk which the Emperor sent to Paris, the approbation of the fatherland could not reach Poland until long afterward, and in tones that were low and almost inaudible. It is an old French saying that next to the kingdom of heaven France is the most beautiful land, and every Frenchman believes it. The Emperor himself said that his French soldiers were unfitted for distant expeditions by their yearnings for home. In his mind, therefore, the one essential thing to restore the spirits of his men was rest. This opinion was strengthened when he endeavored to visit the posts. Although his carriage stuck in the mud and a saddle-horse could scarcely make its way, yet he got far enough to see that his men were suffering and destitute.
