The 26th Army was quickly rebuilt in October 1941 by subsequent reinforcements and included elements of the 1st Guards Special Rifle Corps and now defended the Dnieper river at Kaniev and Rzhishchev south-west of Kiev. 6th and 12th Army ended up in Uman Pocket. 26th Army tried to relieve those armies and attacked in the Boguslav-Zwenigorodka direction. It didn't work. In September 26th Army itself became surrounded in the Kiev Pocket. The Soviets tried to break out, 26th Army was supposed to attack on Lubny. General Kostenko escaped from the encirclement with quite a large group of his soldiers. The army was disbanded and the remaining forces were assigned to the 50th Army.
