Conquering the entire Middle East and China, Genghis Khansent his three tugs, under the command of Subedei and Juchi Khan, to explore the regions lying behind the Caucasus. The Tatar-Mongolian detachment encountered Polovtsian troops there, which were defeated by it. The remnants of the Polovtsians retreated beyond the Dnieper, where they turned to the Russian princes for help.
Mstislav of Kiev became stronger on the hill, where infor three days successfully reflected all the attacks of the Tatar troops. Then the Mongols went to the trick, the leader of the brodlocks Ploskina kissed the cross in front of the prince of Kiev, assuring him that the Tatars would let everyone go home if they lay down their arms. Surrendering, Mstislav surrendered, but the Mongols did not keep their word. All simple soldiers were taken into slavery, and princes and military commanders were put under the flooring, which they sat down to feast, noting the victory. The battle of Kalka was over within three days.
Mongolian troops tried to continuethe offensive on the lands of the Chernigov principality, but, confronted with the first fortified city of Novgorod Seversky, retreated back to the steppes. Thus, the battle of Kalka allowed the Mongols to conduct a thorough reconnaissance battle. They appreciated the Russian army, but in their report to Genghis Khan the absence of unity in the Russian princes was especially noted. During the invasion of Khan Batu into Russia in 1239, the fragmentation of Russia into principalities was widely used by the Mongols.
The battle on the Kalka River showed whatresult in inconsistency of actions. The Russian troops suffered huge losses, no more than a tenth of the warriors returned home. Many noble warriors and princes were killed. The battle on Kalka demonstrated to the Russian princes the might of the new enemy, but the lesson was not learned and the invasion of Mongolian-Tatar hordes after 16 years slowed down the development of Russia almost two and a half centuries.
