After neutralizing the Soviet counter-attack in the Izyum-Barvenkovsk direction the German Army Group A rapidly attacked towards the Caucasus. When Rostov-on-Don, nicknamed "The Gates of Caucasus," fell on 23 July 1942, the tank units of Ewald von Kleist moved towards the Caucasian Mountain Range. The "Edelweiss" division commander, Hubert Lanz, decided to advance through the gorges of rivers of the Kuban River basin and by crossing the Marukhskiy Pass (Maly Zelenchuk River), Teberda, Uchkulan reach the Klukhorskiy Pass, and simultaneously through the Khotyu-tau Pass block the upper reaches of the Baksan River and the Donguz-Orun and Becho passes.
