In the meantime, Sviatopolk was unconsciously facilitating his own downfall. After the Poles had helped him to re-establish himself, he began to feel the oppressive superiority of their presence, and plotted a base design to remove them. He instigated the inhabitants and the soldiery to conspire against the strangers, and massacre them in the midst of their security. Boleslav discovered the plot before it had time to be carried into execution; and, disgusted at a design so cruel and treacherous, he resolved to take ample revenge. The capital was plundered of its accumulated wealth by the incensed Poles, who, but for the moderation of their leader, would have burned it to ashes; and, loaded with treasures, they returned towards the Russian frontiers. Sviatopolk was artful enough to turn the whole transaction to the discredit of his ally, and thus to rouse the courage of his followers, who were easily persuaded to take the field against Boleslav. The belligerents met on the banks of the Bug before the Poles had passed the boundaries. The battle that ensued terminated in the discomfiture of Sviatopolk, who now returned with broken fortunes to the capital which he had so lately entered with acclamations of triumph. This was the opportunity for Iaroslav to appear with his followers. The usurper’s troops were so reduced by his late disasters, that he was forced to seek assistance from the Petchenegs, the hereditary enemies of the country; and they, tempted by hopes of booty, flocked to his standard to resist the approach of Iaroslav. The armies met on a plain near the place where Boris had been assassinated by the command of the fratricide. The coincidence was fortunate, for Iaroslav, taking a prudent advantage of the circumstance, employed all his eloquence in describing to his soldiers the righteousness of the cause in which they were engaged against a second Cain, the shedder of a brother’s blood. His oration, concluding with a fervent prayer to the Almighty to nerve his arm, and direct his sword, so that he might be made the instrument of reparation in so just a fight, wrought powerfully upon the assembled army, and excited them to an unexampled display of bravery. The advantage of numbers was on the opposite side; but such was the courage exhibited by the Novgorodians, that after a desperate battle, which lasted throughout the whole day, they succeeded in putting the enemy completely to flight. Sviatopolk took to horse and fled, but died in a wretched condition on the road.
