The Front was disbanded on 13 March 1919 and the troops transferred to form a separate 11th Army.
The troops of the 11th Army were not able to carry out the assigned tasks, as they were opposed by considerable enemy forces.
The 12th Army was also forced to conduct defensive battles in the districts of Kizlyar and west of Guryev.
In January 1919, the troops of the 11th Army were defeated in the Northern Caucasus Operation (1918–1919) and in February they retreated over the Manych River into the region of Astrakhan.
