Further east, the Axis enjoyed greater success and on 1 September, the Germans took (Хулхута́), halfway between Elista and Astrakhan. During August and September, German patrols raided the railway around Kizlyar, north-east of Grozny, marking the farthest advance of the German forces towards the Caspian Sea. In the south, the First Panzer Army advance on Grozny was stopped by the Red Army and the 14th Air Army. By late September, supply failures and the resistance of the Red Army slowed the Axis advance. The Germans took Nakchik on 26th October.
