The Battle of Volga River was a military engagement between the Umayyads and the Khazars at the Volga near Atil. The battle ended in Umayyad victory. Background In the year 737,Dunlop, D. M, p. 81 the Umayyad governor of Armenia, Marwan ibn Muhammad, launched an invasion into Khazaria. His forces crossed the Darial Gorge and reached Samandar. He had the Khazar ambassador imprisoned before he marched. When he reached there, he released him with a declaration of war. When the ambassador reached the Khagan, Marwan was already deep in enemy territory. From Samandar, the Umayyads reached Atil or Al-Bayda. The Khagan left a considerable force to defend the capital and withdrew north. The Umayyads, however, did not attempt to besiege Atil and instead withdrew to the right bank of the Volga River. Meanwhile, the Khazar army under Hazer Tarkhan marched from Atil and followed the Umayyads on the opposite side of the river.Khalid Yahya Blankinship, p. 172Dunlop, D. M, p. 81-83Artamonov, M. I., p. 220 Battle Marwan appointed his general, al-Kawthar ibn al-Aswad al-Anbari, with a force of 40,000 men to cross the river and look out for enemy attacks and ambush them if found. At first, Al-Kawthar was reluctant but later managed to construct a pontoon bridge to cross the river. After they crossed, the Umayyads found a small party of Khazars, numbering 20 men, hunting. This small force was led by the Hazer Tarkhan himself. The Umayyads overwhelmed and killed them. Soon after in the evening, the Umayyads began constructing their camp. However, they saw smoke arise from the forest. It was the Khazar army encamped for the night. They were unaware of the Arabs nearby. Al-Kawthar quickly charged at the Khazar camp and took them by surprise. The Umayyads quickly gained a victory over them, slaughtering 10,000 and capturing 7,000. The rest fled the battlefield.Dunlop, D. M, p. 83Khalid Yahya Blankinship, p. 173Artamonov, M. I., p. 220-221 Aftermath After the defeat of his forces, the Khagan sued for peace and possibly converted to Islam. Marwan sent two missionaries to teach the Islamic religion to him. Regardless of the reliability of the story, Marwan ended his campaign victoriously. Having captured 40,000 Khazar and Slavic captives, he settled them in Lakia. Many of them were Muslims and moved safely to Umayyad territory.Khalid Yahya Blankinship, p. 173 Afterwards, warfare between the Umayyads and Khazars ceased,Cobb, Paul M. (2010).
