The Battle of the Valerik River on 11 July 1840 was fought as part of the Russian conquest of the Caucasus. It occurred about 30 km (19 miles) southwest of the fortress of Groznaya (now Grozny) between forces of the Imperial Russian Army and North Caucasian mountaineers led by the naib (viceroy) Ahberdila Muhammad. It remains famous because of the poem "Valerik" by Mikhail Lermontov, a participant.
