Conquest of Georgia and Armenia

The Mongols under Chormaqan returned to the Caucasus in 1232. The walls of Ganjak were breached by catapult and battering ram in 1235. The Mongols eventually withdrew after the citizens of Irbil agreed to send a yearly tribute to Ögedei's court. Chormaqan waited until 1238, when the force of Möngke Khan was also active in the north Caucasus. After subduing Armenia, Chormaqan took Tiflis. In 1238, the Mongols captured Lorhe whose ruler, Shahanshah, fled with his family before the Mongols arrived, leaving the rich city to its fate. After putting up a spirited defense at Hohanaberd, the city's ruler, Hasan Jalal, submitted to the Mongols. Another column then advanced against Gaian, ruled by Prince Avak. The Mongol commander Tokhta ruled out a direct assault and had his men construct a wall around the city, and Avak soon surrendered. By 1240, Chormaqan had completed the conquest of Transcaucasia, forcing the Georgian nobles to surrender.
