Oleg and Davyd in the united coalition of Sviatoslavichi managed to recover Smolensk and defeated Izyaslav at Murom where the last one perished.
Davyd sent along his son Sviatoslav, but after an unsuccessful campaign the last one came back to his father and upon the death of his wife became a monk.
At the Council of Witchew between the Sviatoslavichi, Monomakh, and Sviatopolk agreed to peace, stop the civil war, and consolidated their forces against the foreign enemies.
During that campaign they managed to occupy the Cuman cities of Sharukan which is believed to be located somewhere between Chuhuiv and Zmiiv, and Sugrov.
His son Sviatoslav Davydovich is also known as Saint Nicholas / Nikola Sviatosha, wonderworker of the Kiev Caves.
