Jebe vs Zong Ze

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.

During the Great Raid, Jebe defeated the Kipchak (Cuman) confederation in the Caucasus. The victory broke the power of the Kipchaks in the region and forced them to flee westward, where they later allied with the Rus' against the Mongols.

Jebe and Subutai's Mongol army defeated a coalition of Rus' principalities and Cumans at the Kalka River. The victory was a major demonstration of Mongol military capability against European forces, though the Mongols did not follow up immediately.

Zong Ze was appointed Prefect of Kaifeng after the Jin withdrew, organizing defenses and training militias. He restored order and prepared the city for future attacks, becoming a symbol of resistance.

Zong泽 repeatedly petitioned Emperor Gaozong to launch a campaign to recover northern territories from the Jin. His calls were ignored as the court favored peace, leading to his frustration and eventual death.

Zong Ze died of illness while preparing a major offensive against the Jin. His death ended the most credible threat to Jin control of the north, and his plans were never executed.
