The Battle of Balanjar took place during the Khazar–Arab Wars. The Umayyads crushed the Khazar army and captured Balanjar after a heavy battle. Battle After the victory at Derbent in 722, the Umayyads, under the general Al-Jarrah ibn Abdallah, marched towards the city of Balanjar. The city already witnessed a failed Arab attack in 652. The strong fortifications prevented the Arabs from capturing it. After 70 years of that defeat, its defenses were dismantled. The inhabitants of the town were surprised by Al-Jarrah's invasion and defended the town using 3,000 wagon barricades tied together on high ground around Balanjar. Behind the wagons was the Khazar army defending itself.Dunlop, D. M, p. 64Artamonov, M. I, p. 207

The Umayyads began their assault on the Khazars but soon found themselves in a difficult position. A heavy barrage of arrows bombarded the Umayyads. One of the soldiers began exhorting his men to fight, in which he was joined by the rest. They charged against the wagons under a barrage of arrows, which reportedly covered the sunlight. They made their way up the hill. Some of them managed to cut the ropes that bound the wagons together and drag them down the hill slope. This caused a gap for the Umayyads, which they quickly charged at. Both sides fought bravely, but the Khazars were defeated; many were killed and captured,Dunlop, D. M, p. 65Artamonov, M. I, p. 207 and soon Balanjar fell to the Muslims on 21 August.Khalid Yahya Blankinship, p. 122

The governor of Balanjar escaped with 50 men. His camp, along with all his property, wives, and children, fell to the victors. The booty was so great that each Arab horseman received property worth 300 dinars. The family of the governor was released by Al-Jarrah and granted safe conduct to Khazaria.Dunlop, D. M, p. 65Artamonov, M. I, p. 207 Aftermath The neighboring towns were subjugated, and the majority of the inhabitants of Balanjar emigrated north.Dunlop, D. M, p. 65 The Umayyads then continued their campaign, marching all the way to Samandar. However, they retreated on the approach of a large Khazarian army. Al-Jarrah would continue his operations against the Khazars in the following years.Khalid Yahya Blankinship, p. 122 References
