Bohemond I of Antioch vs Kang Kam-chan

Bohemond led the capture of Antioch during the First Crusade. He negotiated with a traitor inside the city to open a gate, allowing the crusaders to enter. He then claimed the city for himself, becoming Prince of Antioch.

Bohemond and Baldwin of Edessa were defeated by a combined Seljuk force at the Battle of Harran. Bohemond was captured and held for ransom, weakening the Principality of Antioch.

After his release, Bohemond launched a campaign against the Byzantine Empire, besieging Dyrrhachium. He was forced to surrender in 1108 and sign the Treaty of Devol, which made Antioch a vassal of Byzantium.

Bohemond signed the Treaty of Devol with Byzantine Emperor Alexios I Komnenos. The treaty recognized Bohemond as Prince of Antioch but made him a vassal of the Byzantine Empire, a humiliation that ended his ambitions.

During the Second Goryeo-Khitan War, Kang Kam-chan successfully defended the fortress of Heunghwajin against a Khitan siege. His stubborn resistance bought time for Goryeo to regroup and negotiate a truce.

King Hyeonjong appointed Kang Kam-chan as supreme commander of Goryeo's forces during the Third Khitan War. This appointment gave him authority over all military operations and reflected the king's trust in his strategic abilities.

General Kang Kam-chan led Goryeo forces to a decisive victory over the Khitan Liao dynasty at Gwiju. The battle ended the Third Goryeo-Khitan War, with Goryeo inflicting heavy casualties and forcing the Khitan to withdraw permanently.
