On September 29, German troops launched an offensive. The main blow was struck at the junction between the Southwestern and Southern Fronts in the area of the city of
Novomoskovsk. On the same day, the troops went on the offensive in auxiliary directions. Quickly breaking through the weak Soviet defenses, the German 1st Panzer Army rushed into the breakthrough. Having traveled over 200 kilometers in 9 days, on October 7, north of Osipenko, the 1st Panzer Army joined up with the mobile units of the 11th Army. The command of the Southern Front made efforts to withdraw its troops from the outlined grandiose "cauldron", having reported this to the Headquarters of the Supreme High Command and received the appropriate permission on October 3. On October 4, the 12th Army left Zaporozhye and retreated to the
Pavlograd,
Vasilkovka, Gavrilovka line. But the main forces of the 18th Army and part of the forces of the 9th Army were surrounded north of Osipenko (in total, up to 6 divisions). The command of the encircled group was headed by the commander of the 18th Army, Andrei Smirnov. This group fought until October 10, when the commander was killed in action during a night breakout attempt. On that day, her main forces were cut into pieces and stopped organized resistance. The losses of the Soviet troops were great. The German press reported the capture of 100,000 soldiers of the Workers' and Peasants' Red Army, 212 tanks and 672 guns. However,
Erich von Manstein, a direct participant in those events, indicated less data in his memoirs: "We captured 65 thousand prisoners, 125 tanks and over 500 guns in a round–robin manner". On October 5, the commander of the troops of the Southern Front, Dmitry Ryabyshev, and a member of the Military Council, Alexander Zaporozhets, were removed from their posts. Cherevichenko was appointed commander of the front. At the same time, the lag of the German infantry units from the tank groupings did not allow the German command to create a continuous front of encirclement. The main forces of the 9th and 12th Armies, as well as part of the forces of the 18th Army, managed to break through the scattered battle formations of the enemy. The Headquarters of the Supreme High Command transferred 5 rifle divisions to the Southern Front on October 7 and demanded by October 13 to create a stable front line along the line of the Mius River. The Taganrog Combat Area (3 rifle divisions) was also created. In the north, the 6th Army withdrew 25–30 kilometers by October 11, having managed to pin down the main forces of the 17th German Army. But the German command acted promptly: already from October 9–10, the main forces began to transfer the main attack to the east, trying to prevent the Soviet troops from gaining a foothold. The 1st German Panzer Army was immediately redirected to the Rostov Direction and by the end of October 13 had reached the
Taganrog Region. There, on October 11, the Soviet command hastily created the Taganrog task force consisting of 3 rifle and 3 cavalry divisions, two military schools and a regiment of the People's Commissariat of Internal Affairs (Commander Lieutenant General
Fyodor Remezov), which in heavy battles managed to hold back the German offensive. On October 14, the 9th Army and the Taganrog Combat Area (troops of the Southern Front) launched a counterstrike in the Taganrog area against the enemy's forward units. On this day, they pushed the enemy forward units 10–15 kilometers away. But by the end of the same day, the approaching main forces of the 1st German Panzer Army were thrown into battle on the move. Poorly trained Soviet troops began a hasty retreat, and on their shoulders, German troops broke into Taganrog by nightfall (after street fighting, it was finally captured by the enemy on October 17). By the beginning of November, the troops of the right wing of the Southern Front (12th Army), by order of the Headquarters of the Supreme High Command, withdrew to the
Krasny Liman,
Debaltsevo line, and the troops of its left wing (18th and 9th Armies), under pressure from superior German forces, to the line
Debaltsevo –
Krasny Luch – Bolshekrepinskaya –
Khapry, where they took up defensive positions. The
Donbas Defensive Operation has been completed. ==Operation progress: second stage==
