Without realizing it I had posted
how some of the Soviet forces faired during the Uman Encirclement
Strenght of the 12th Army (I) on 22nd July 1941 (about the start of the encirclement)
44th Mountain Rifle Division (40%) ># 19.09.1941
58th Mountain Rifle Division (25%) ># 19.09.1941
60th Mountain Rifle Division (60%) ># 19.09.1941
72nd Mountain Rifle Division (35%) ># 19.09.1941
99th Rifle Division (20%)
192nd Mountain Rifle Division (30%) ># 19.09.1941
491th Rifle Regiment (20%)
Going by the strenghts of its component divisions it appears that the 12th Army (I) was already wrecked at the start of the battle.
The same document list the strenght of the 6 Army (I) on 15th August 1941 after the encirclement was over (the parts of the army that had escaped the encirclement)
80 th Rifle Division (20%) ># 19.09.1941
139 th Rifle Division (10%) ># 19.09.1941
140th Rifle Division (10%) ># 19.09.1941
141st Rifle Division (25%) ># 19.09.1941
189th Rifle Division (25%) ># 19.09.1941
190th Rifle Division (10%) ># 19.09.1941
197th Rifle Division (15%) ># 19.09.1941
This indicates that somewhere between 10% and 25% of the Soviet forces invovled in the encirclement escaped
Also listed is the disbandment date (>#) of the divisions. This indicates a number of things
1.) All the division except 99th Rifle Division (I) probably escaped the pocket as small groups of men, losing almost all their equipment. The structure of the division had been destroyed and they couldn’t be rebuilt.
2.) The 99th Rifle Division (I) retained enough of its structure to be rebuilt.
3.) The official tally for what had happened at Uman took about a month to complete, when the affected units were stricten from the lists.
