More troops were brought in and on 2 January Khanzhalmikhe fell and 140 prisoners taken. This is the only mention of prisoners taken throughout the war. Gunib was relieved the next day. North up the canyon was Gerghebil which was considered the key to the relief of Kunzakh. On 7 or 8 January 2686 men began the attack. On 26 January the place fell to a night attack. Todorsky justified the heavy losses on the grounds that difficult victories demoralized the enemy. Two days later Khunzakh was relieved for a second time.

On 18 February it surrendered. With the core area occupied other places began to surrender. On the 19th Ashitla west of Gimry was occupied by 125 officer cadets. All were killed during the night and the next day 52 mutilated bodies were found. It is not clear what provoked this unusual brutality. The area to the northwest to the Chechen border was occupied: Botlikh , Andi  and northward . On 9-13 March the Dagestan Reds linked up with those in Chechnya. On 15 March the Petrovsk Military Soviet declared the uprising liquidated. Meanwhile, on 25 February, Tiflis was occupied by the Red army. With Georgia now under Soviet control the remaining rebels in Dagestan were surrounded. The rebels made their last stand at Gidatl where the uprising was first organized. It fell in May.

The war took the lives of 5000 Reds and an unknown number of mountaineers.
