The immediate and inevitable consequence of the battle was a sensible reduction of the Russian army. The numbers that fell before the Tatars could not be easily or speedily supplied: nor were the means of a fresh levy accessible. Those districts from which the grand army was ordinarily recruited had already exhausted their population; all the remote principalities had contributed in nearly equal proportion, and the majority of the rest of the empire was composed of persons who were unaccustomed to the use of arms, having been exclusively occupied in tillage or commerce. These circumstances, which did not damp the joy of the victory, or diminish its real importance, presented to the implacable foe a new temptation for crossing the border. But it was not until two of the wandering hordes had formed a junction that the Tatars were able to undertake the enterprise. The preparations for it occupied them two years. In 1382, the hordes of the Don and the Volga united, and making a descent upon the frontier provinces with success, penetrated as far as Moscow. The city had been previously fortified by the boyars with strong ramparts and iron gates; and Dmitri, trusting with confidence to the invincibility of the fortifications, left the capital in the charge of one of his generals, while he imprudently went into the interior to recruit his army. His absence in the hour of danger spread consternation amongst the peaceable part of the inhabitants, particularly the clergy, who relied upon his energies on the most trying occasions. The metropolitan, accompanied by a great number of the citizens, left the city upon the approach of the Tatars. The small garrison that remained made an ineffectual show on the ramparts, and the Tatars, who might not otherwise have gained their object, prevailed upon the timidity of the Russians, who consented to capitulate upon a promise of pardon. The Tatars observed their pledge in this instance as they had done in every similar case--by availing themselves of the first opportunity to violate it. They no sooner entered Moscow than they gave it to the flames, and massacred every living person they met in the streets. Having glutted their revenge with a terrible scene of slaughter and conflagration, they returned home, satisfied with having reduced the grand princedom once more, after their own fashion, to subjection. They did not perceive that in this exercise of brutal rage they strengthened the moral power of Russia, by giving an increased motive to co-operation, and by rendering the abhorrence of their yoke still more bitter than before. All they desired was the physical and visible evidence of superiority; either not heeding, or not comprehending, the silent and unseen progress of that strength which combined opinion acquires under the pressure of blind tyranny.
