Jebe and Subutai led a 20,000-man Mongol army on a multi-year reconnaissance raid through the Caucasus and into the Pontic steppes. They defeated the Cumans and a coalition of Rus' princes at the Battle of the Kalka River in 1223.

Jebe led a detachment of 10,000 men to pursue Muhammad II of Khwarezm across Persia. He chased the fleeing shah to the Caspian Sea, where Muhammad died on an island. The pursuit demonstrated Mongol strategic mobility and intelligence gathering.
