The Battle of Uman (15 July – 8 August 1941) was the World War II German offensive in Uman, Ukraine against the 6th and 12th Soviet Armies. In a three-week period, the Wehrmacht encircled and annihilated the two Soviet armies.
The battle occurred during the Kiev defensive operation between the elements of the Red Army's Southwestern Front, retreating from the Lwow salient, and German Army Group South, commanded by Field Marshal Gerd von Rundstedt, as part of Operation Barbarossa.
The Soviet forces were under overall command of the Southwestern Direction, commanded by Marshal Semyon Budyonny, which included the Southwestern Front commanded by Colonel General Mikhail Kirponos and Southern Front commanded by General Ivan Tyulenev. The 6th army was commanded by Lieutenant General I. N. Muzychenko and the 12th army by Major General P. G. Ponedelin.
Prelude In the initial weeks of Operation Barbarossa, Army Group South had rapidly advanced East, defeating several Soviet mechanized corps at the Battle of Brody 23–30 June. The armies of the Southwestern Front were ordered to retreat to the line of fortifications along the old Soviet-Polish border of 1939 (Stalin Line). III and XXXXVIII Motorized corps of the 1st Panzer Group wedged in between the 5th Soviet army and 6th Soviet army. On 7 July, XXXXVIII Motorized Corps cracked a weak defense on the Stalin Line and began to move rapidly, embracing the right flank of the 6th Army. A new Soviet counter-attack was attempted on 9 July in the direction of Berdychiv to prevent further advance of the 1st Panzer Group to the east. The fighting continued until 16 July, the 11th Panzer Division lost 2,000 men, but finally Soviet troops failed and on 16 July the German offensive continued.
Further to the north, the mobile units of the III Motorized Corps also overcame the Stalin Line and reached the approaches to Kiev. The command of Army Group South intended to capture Kiev quickly, while Hitler and the High Command insisted on a strike in the southern direction, which guaranteed the encirclement of the Soviet troops in conjunction with the 11th Army (Wehrmacht). The compromise solution proposed the capture of Belaya Tserkov and after that a strike in the south-west direction towards the 11th Army. Such a decision left the possibility, instead of a strike to the southwest, to continue the offensive from Kiev farther east, beyond the Dnieper River. But Kiev was secured by a separate fortified area, and the rear communications of the III Motorized Corps were under attack from the 5th Army.
So, in the opening days of Battle of Uman the task of encircling the 6th and 12th armies from the north and the east was to be done by divisions of the XXXXVIII Motorized Corps only. To help them, the third unit of the 1st Panzer Group, the XIV Motorized Corps, was transferred from the south and committed to action between the III and XXXXVIII Motorized corps in the direction to the Belaya Tserkov.
Infantry units of the German 6th Field Army on the north hastened to replace the advanced tank units, the 17th Field Army on the west continued to pursue retreating forces of the Soviet 6th and 12th armies. The advance of the 11th Field Army from the Soviet-Romanian border was suspended by Soviet counterblows, and its attack from the south towards Vinnytsia was postponed.
Orders of battle Most of the Soviet forces were severely depleted, having withdrawn under heavy assaults from the Luftwaffe from the Polish border, and the mechanised units were virtually reduced to a single "Corps" after the Brody counter-offensive, its mechanised infantry now fighting as ordinary rifle troops.
The Axis forces were divided into those of 1st Panzer Group that had suffered significant losses in matériel, but retained combat effectiveness, and the large infantry formations of the German and Romanian armies that attempted to advance from the West to meet the armored troops north of Crimea, the initial strategic objective of Army Group South.

The battles of encirclement The first stage Since 15 July, the XLVIII Motorized Corps of Wehrmacht repulsed the counter-attacks of the Soviet "Berdichev Group" and resumed the offensive. The 16th Panzer Division broke the resistance of the Soviet troops and seized the city of Kazatin ( 25 km from Berdichev). On the left, the 11th Panzer division was in the gap between Soviet armies, so by 16 July it made a deep (70 km) breakthrough to the South-East. By 18 July, the division advanced another 50 km, crossed the Ros River and captured Stavishche. The 16th Panzer Division, which was forced to repel counterattacks of the Soviet 6th Army (37th Rifle Corps and "Berdichev Group" ), advanced slower, but by 17 July its forward detachment seized the ( 65 km from Berdichev), where was an important Soviet base of rear services support. 18 July, units of the 6th army managed to recapture the station.
Further to the North, the XIV Motorized Corps advanced to Belaya Tserkov, but met counterattacks by the 26th Army. This army had no time to prepare the offensive, and its divisions didn't have time to concentrate. They couldn't beat out the 9th Panzer Division from Belaya Tserkov. Nevertheless, they for a short time captured Fastov. The advance of the 26th Army soon stopped, but its attacks contained the mobile units of the 1st Panzer Group. A similar situation was with the Panzer divisions of the III Motorized Corps. Franz Halder, the chief of OKH, irritably wrote on 18 July that "the operation of the Army Group "South" is increasingly losing its shape", and that "enveloping flank of the 1st Panzer Group is still hang about in the area of Berdichev and Belaya Tserkov". At the same time the 17th Field Army from the West was approaching too quickly and Halder feared that the future "cauldron" would not trap significant enemy forces.
Meanwhile, the 17th Field Army tried to implement a shortcut version of the original plan, according to which the Soviet troops were to be surrounded to the west of Vinnytsia. But now Germans had no mobile units to hit Vinnytsia from the North (they operated east of Berdichev), and the offensive of 11th Field Army from the south was postponed. Therefore, from the north to Vinnitsa 24 ID was marching. From the south-west on 17 July the 1st Mountain Division came and took under fire bridges across the Southern Bug river. In case of German success, 50,000 troops from the Soviet 12th army would have been surrounded there. However, the Soviet troops regrouped, and from the Southern Front a fresh mountain rifle division was transferred, so they managed to contain the advance of the German infantry, and by 21 July to retreat through Vinnytsia across the Southern Bug river.
By 18 July, the Soviet command realized that they did not have enough forces to seal the breakthrough of the 1st Panzer Group and restore the defense along the "Stalin Line". Budyonny noted that on the right flank of the Soviet 6th army was a gap of 90 km, which is gradually filled with German troops. As a result, it was decided to withdraw the 6th and 12th army on the line of Belaya Tserkov – Tetiev – Kitay-Gorod – Haisyn (80–100 km East of the line Berdichev – Vinnitsa). The 18th army of the Southern Front, adjacent to the left flank of the 12th army, also received an order to withdraw. The departure was to take place at night and be completed by 21 July. The problem was that the German tanks of the XXXXVIII and XIV Motorized corps had already broken through this line. However, the Soviet command planned to fix this problem by the offensive of three infantry corps, which was to strike South-West from Kiev. In addition, on 18 July the 2nd Mechanized Corps received an order to transfer from Southern Front to Uman, to meet the XXXXVIII Motorized Corps of the Germans. In turn, High Command of the Wehrmacht on 19 July decided to change the Barbarossa plan. Units of the Army Group "Center", instead of attacking Moscow, had to hit the South and North to surround the Soviet troops and prevent their withdrawal. The close task of the Army Group "South" was the encirclement of the 6th and 12th Soviet armies West of the Dnieper. At the same time, on 18 July, Halder and the command of the Army Group "South" decided that the attack on Uman would not be sufficient. At Uman had to go only part of the right flank of the 1st Panzer Group, and the main blow should be directed further to the East, towards Krivoy Rog.
Attempts to retreat The second stage of the first offensive of the 26th Army began on 18 July, but also ended in failure. Thanks to the intercepted radio message, the German command knew about it in advance. Because of the north part of the line for retreat remained in the hands of the Germans, the 6th Army began to retreat in the South-Eastern direction, while preparing a counterattack against the German troops flanking it from the North-East. The counterattacks of the 6th and 12th armies near Orativ – Monastyrysche began on 21 July and forced the 16th Motorized and the 16th Panzer divisions to go on the defensive. The Soviet 2nd Mechanized Corps, further to the East, attacked the 11th Panzer Division and stopped its advance to Uman. By stopping the advance of the German strike wedge, Soviet troops were able to continue the retreat, although the gap with the 26th Army remained. Halder was forced to admit: "The enemy again found a way to withdraw his troops from the threat of an emerging encirclement".
