But Mstislaf fell upon them with such impetuosity that they were routed with great slaughter and driven back to their wilds.

Their chastisement was so severe that, for a long time, they were intimidated from any further incursions.

With wonderful energy, Mstislaf attacked many of the tributary nations, who had claimed a sort of independence, and who were ever rising in insurrection.

He speedily brought them into subjection to his sway, and placed over them rulers devoted to his interests.

In the dead of winter an expedition was marched against the Tchoudes, who inhabited the southern shores of the bay of Finland.
