As Sviatoslaf, with his shattered army, ascended the Dnieper in their boats, the Petchenegues, fierce tribes of barbarians, whom Sviatoslaf had subdued, rose in revolt against him. They gathered, in immense numbers, at one of the cataracts of the Dnieper, where it would be necessary for the Russians to transport their boats for some distance by land. They hoped to cut off his retreat and thus secure the entire destruction of their formidable foe. The situation of Sviatoslaf was now desperate. Nothing remained for him but death. With the abandonment of despair he rushed into the thickest of the foe, and soon fell a mangled corpse. How much more happy would have been his life, how much more happy his death, had he followed the counsels of his pious mother. Kouria, chief of the Petchenegues, cut off the head of Sviatoslaf, and ever after used his skull for a drinking cup. The annalist Strikofski, states that he had engraved upon the skull the words, "In seeking the destruction of others you met with your own." A few fugitives from the army of Sviatoslaf succeeded in reaching Kief, where they communicated the tidings of the death of the king. The empire now found itself divided into three portions, each with its sovereign. Yaropolk was supreme at Kief. Oleg reigned in the spacious country of the Drevliens. Vladimir was established at Novgorod. No one of these princes was disposed to yield the supremacy to either of the others. They were soon in arms. Yaropolk marched against his brother Oleg. The two armies met about one hundred and fifty miles north-west of Kief, near the present town of Obroutch. Oleg and his force were utterly routed. As the whole army, in confusion and dismay, were in pell-mell flight, hotly pursued, the horse of Oleg fell. Nothing could resist, even, for an instant, the onswelling flood. He was trampled into the mire, beneath the iron hoofs of squadrons of horse and the tramp of thousands of mailed men. After the battle, his body was found, so mutilated that it was with difficulty recognized. As it was spread upon a mat before the eyes of Yaropolk, he wept bitterly, and caused the remains to be interred with funeral honors. The monument raised to his memory has long since perished; but even to the present day the inhabitants of Obroutch point out the spot where Oleg fell. Vladimir, prince of Novgorod, terrified by the fate of his brother Oleg, and apprehensive that a similar doom awaited him, sought safety in flight. Forsaking his realm he retired to the Baltic, and took refuge with the powerful Normans from whom his ancestors had come. Yaropolk immediately dispatched lieutenants to take possession of the government, and thus all Russia, as a united kingdom, was again brought under the sway of a single sovereign. CHAPTER III.
