Most dangerous to the Poles was Volodar, who had as allies tribes in Pomoria and in Prussia on the Baltic. These tribes were hostile to the Poles. The question now was to stop Volodar. At the court of Boleslav there lived Peter Vlast, a Dane of many adventures, who advised the king not to meet Prince Volodar in battle, but to kidnap him, and promised, if permission were given, to accomplish the deed himself. The king was pleased, and Vlast, who had gained much renown through marvelous exploits, set out with thirty men to win the confidence of Volodar and capture him. He appeared before the prince and, feigning himself an exile in deadly enmity with Boleslav, quickly won Volodar’s good-will and confidence. Some weeks later the prince took Vlast to a hunt in a great forest where, adroitly separated from his own people, Volodar was seized by Vlast’s men, who bore him beyond the boundary and never drew rein till they delivered him safely to Boleslav. The king was triumphant. Vassilko the Blind gave all the money that he and his brother possessed to free Volodar; besides this, those two sons of Rostislav swore to act with the Poles against every enemy. In 1123 Yaroslav, son of Sviatopolk, appeared at Vladimir with immense forces,—Cheks, Poles and Hungarians, bringing also as allies Volodar and Vassilko. Monomach’s son, Andrei, who was prince there, defended the city. Monomach sent forward Mystislav, and also hurried men from Kief, but before Mystislav could arrive the siege was well ended. Early one Sunday morning Yaroslav rode toward the walls with two attendants, and shouted to Andrei and the citizens: “This city is mine! Open ye the gates and come out to me with homage. If not I will storm the place to-morrow and take it.” While he was thus riding in front of the city and boasting, two Poles, employed, as is said, by Andrei, slipped out and hid near the wayside. When the prince was retiring from the walls, they sprang up and sent a spear through his body. He reached camp, barely living, and died a few hours later. Stephen II, King of Hungary, thought to continue the siege, but the chiefs of his army were opposed to shedding blood without profit. In view of this, the allies of Yaroslav, the late prince, made peace with the Kief prince and retired each to his own land. Through Yaroslav’s death Sviatopolk’s descendants lost the Kief succession. Four years later his younger sons, Izyaslav and Bryache, died, so that Volynia and Turoff went to Monomach’s descendants.
