The Siege ofKyiv by the Pechenegs in 968 is documented in the Primary Chronicle, an account that freely mixes historicaldetails with folklore. According to the chronicle, while Svyatoslav I of Kyiv was pursuing his campaign against the First Bulgarian Empire, the Pechenegs invaded Rus and besieged his capital of Kyiv. While the besieged suffered from hunger and thirst, Svyatoslav's general Pretich deployed his druzhina, his personal guard, on the opposite bank of the Dnieper, not daring to cross the river against the larger Pechenegforce. Reduced to extremes, Svyatoslav's mother Olga of Kyiv contemplated surrender if Pretich did not relieve the siege within one day. She was anxious to send word about her plans to Pretich. At last a boy fluent in the Pecheneg language volunteered to venture from the city and urge Pretich to action. Pretending to be a Pecheneg, he went about their camp, as if searching for a lost horse. When he attempted to swim across the Dnieper, the Pechenegs discovered his subterfuge and started shooting at him, but to no avail. When the boy reached the opposite bank and informed Pretich about the desperate condition of the Kyivans, the general decided to make a sally in order to evacuate Svyatoslav's family from the city, for fear of his sovereign's anger. Early in the morning Pretich and his troops embarked on boats across the Dnieper, making great noise with their trumpets. The besieged started cheering and Olga ventured out of the city towards the river. The Pechenegs, thinking that Svyatoslav was returning with his great army, lifted the siege. . The Pecheneg leader then decided to confer with Pretich and asked him whether he was Svyatoslav. Pretich admitted that he was only a general but warned the Pecheneg ruler that his unit was a vanguard of Svyatoslav's approaching army. As a sign of his peaceful disposition, the Pecheneg ruler shook hands with Pretich and exchanged his own horse, sword, and arrows for Pretich's armor. As soon as the Pechenegs retreated, Olga sent a letter to Svyatoslav reproaching him for his neglect of his family and people. Upon receiving the message, Svyatoslav speedily returned to Kyiv and thoroughly defeated the Pechenegs, who were still threatening the city from the south. The following year Olga died and Svyatoslav moved his capital from distant Kyiv to Pereyaslavets in present-day Romania.
