Military campaigns
Campaign against the tribes of Yem (Yam)
It is known that the Kyiv troops defeated the enemy, captured prisoners and valuable booty, but on the way back there was a big loss of horses.
In the year 6550 (1042). Vladimir, the son of Yaroslav, went to Yam and defeated them. And the horses of the Vladimir warriors died, and if the horse was still breathing, they skinned it: there were many deaths among the horses. – The Tale of Bygone Years[2]wikipedia
Campaign to Constantinople
The campaign ended in complete failure. The abundant use of Greek fire, as well as the storm that broke out during the battle, gave the Byzantines a decisive advantage. The storm swept the Old Rus fleet in different directions, many ships perished, including the boat of Vladimir Yaroslavich, but the prince escaped by switching to another ship.
Vyshata volunteered to lead the Old Rus soldiers thrown ashore, but near Varna their group was overtaken by the Byzantine strategist Katakalon Kekavmen, as a result of which most of them were killed and the rest were captured.
Vladimir Yaroslavich was forced to retreat. The emperor of Byzantium sent 24 dromons in pursuit of the Kievan prince. In one of the bays, Vladimir attacked his pursuers and defeated them (possibly during the coastal parking), after which he safely returned to Kyiv.
Sophia Cathedral in Novgorod
After the consecration, Vladimir Yaroslavich lived for less than a month and was buried in the newly built cathedral.
