It was as follows: "In appropriating to yourself illegally the treasures of the Russian prince, you have violated the Christian virtues.

I conjure you, in the name of God, to restore to him all the property of which you and your subjects have deprived him; for robbers can never enter the kingdom of heaven unless they first restore the plunder they have taken." Fortunately for the fugitive prince, his usurping brother Sviatoslaf just at this time died, in consequence of a severe surgical operation.
The Polish king appears to have refunded the treasure of which he had robbed the exiled monarch, and Ysiaslaf, hiring an army of Polish mercenaries, returned a second time in triumph to his capital.

It does not appear that he subsequently paid any regard to the interposition of the pope.
We have now but a long succession of conspiracies, insurrections and battles.

In one of these civil conflicts, Ysiaslaf, at the head of a formidable force, met another powerful army, but a few leagues from Kief.

In the hottest hour of the battle a reckless cavalier, in the hostile ranks, perceiving Ysiaslaf in the midst of his infantry, precipitated himself on him, pierced him with his lance and threw him dead upon the ground.
