Abwehr's Nordkaukasische Sonderkommando Schamil landed in several points in Chechnya, coordinating strikes with rebels. On 25 September 1942 German paratroopers landed in Dachu-Borzoi and Duba-Yurt and took the Grozny petroleum refinery, to prevent its destruction by the Red Army in case of its retreat. Then they united with the rebels, trying to hold the refinery before the German First Panzer Army arrived. However, on 25-27 September the German tank army was defeated and the saboteurs were forced to retreat.
The Germans made concerted efforts to reach a concerted effort with Khasan, but they found his refusal to cede control of his revolutionary movement to the Germans, and his continued insistence on German recognition of Chechen independence, led many Germans to consider Khasan Israilov as unreliable, and his plans unrealistic. Although the Germans were able to undertake covert operations in Chechnya - such as the sabotage of Grozny oil fields - attempts at a German-Chechen alliance floundered.
The insurrection provoked many Chechen and Ingush soldiers of the Red Army to desert. Some sources claim that total number of deserted mountaineer soldiers reached 62,750, exceeding the number of mountaineer fighters in the Red Army.
