Battle of Smolensk (1941)

Prior to the German attack, the Soviets launched a counter-offensive; on 6 July, the 7th and 5th Mechanized Corps of the Soviet 20th Army attacked with about 1,500 tanks near Lepiel. The result was a disaster, as the offensive ran directly into the anti-tank defenses of the German 7th Panzer Division and the two Soviet mechanized corps were virtually wiped out.[17]

On 10 July, Guderian's 2nd Panzer Group began a surprise attack over the Dnieper, his forces overran the weak 13th Army and by 13 July, Guderian had passed Mogilev, trapping several Soviet divisions. His spearhead unit, the 29th Motorised Division, was already within 18 km (11 mi) of Smolensk. The 3rd Panzer Group had attacked, with the 20th Panzer Division establishing a bridgehead on the eastern bank of the Dvina river, threatening Vitebsk. As both German panzer groups drove east, the 16th, 19th and 20th armies faced the prospect of encirclement around Smolensk. From 11 July, the Soviets tried a series of concerted counter-attacks. The Soviet 19th Army and 20th Army struck at Vitebsk, while the 21st and the remnants of the 3rd Army attacked against the southern flank of 2nd Panzer Group near Bobruisk.[15]

Several other Soviet armies also attempted to counter-attack in the sectors of the German Army Group North and Army Group South. This effort was apparently part of an attempt to implement the Soviet prewar general defense plan. The Soviet attacks managed to slow the Germans but the results were so marginal that the Germans barely noticed them as a large coordinated defensive effort and the German offensive continued.[18]

Hoth's 3rd Panzer Group drove north and then east, parallel to Guderian's forces, taking Polotsk and Vitebsk. The 7th Panzer Division and 20th Panzer Division reached the area east of Smolensk at Yartsevo on July 15. At the same time, the 29th Motorized Division, supported by the 17th Panzer Division broke into Smolensk, captured the city except for the suburbs and began a week of house-to-house fighting against counter-attacks by the 16th Army. Guderian expected that the offensive would continue towards Moscow as its main focus and sent the 10th Panzer Division to the Desna River to establish a bridgehead on the east bank at Yelnya and cleared that as well by the 20th. This advanced bridgehead became the center of the Yelnya Offensive, one of the first big coordinated Soviet counter-offensives of the war.[19]

This objective (Yelnya) was 70 km (43 mi) south of the Dnieper and well clear of the objective of liquidating the armies trapped at Smolensk. Under Fuhrer Directive 33 issued on July 14, the main effort of the Wehrmacht was re-orientated away from Moscow towards a deep encirclement of Kiev in Ukraine and Bock was becoming impatient, wanting Guderian to strike north and link up with Hoth's Panzer Group so resistance in the city could be mopped up.[19][20]

On July 27, Bock held a conference at Novy Borisov, which was also attended by Commander-in-Chief Walther von Brauchitsch, the head of the Oberkommando des Heeres (OKH), the Supreme High Command of the Wehrmacht. The generals were required to sit without an opportunity to comment, while a memorandum was read to them by one of Brauchitsch's aides, instructing them that they were to strictly follow Fuhrer Directive 33 and were under no circumstance to try to push further east. They were ordered to concentrate on mopping up, refurbishing equipment, restocking supplies and straightening the German front line, which had become more of an "S" shape, due to the advances of Guderian and Hoth. Coming away from this meeting, Hoth and Guderian were angry and frustrated. Guderian wrote in his journal that night that Hitler "preferred a plan by which small enemy forces were to be encircled and destroyed piecemeal and the enemy thus bled to death. All the officers who took part in the conference were of the opinion that this was incorrect". Whether or not this was true, it was this meeting that some have pointed to that marked a critical point where the Wehrmacht leadership broke trust with Hitler. After returning to his post, Guderian conspired with Hoth and Bock to "delay the implementation" of Directive 33, in defiance of the orders of the Fuhrer and OKH. Guderian hastily put together a plan of attack for his and Hoth's forces for August 1, the Roslavl-Novozybkov Offensive Operation.[21]

In the north, the 3rd Panzer Group was moving much more slowly. The terrain was swampy, made worse by rain and the Soviets were fought to escape the trap. On 18 July, the armored pincers of the two panzer groups came within 16 km (9.9 mi) of closing the gap. Timoshenko put newly promoted Konstantin Rokossovsky, who had just arrived from the Ukrainian front, in charge of assembling a stopgap force, which held the attack of the 7th Panzer Division and with continuous reinforcements, temporarily stabilized the situation. The open gap allowed Soviet units to escape that were then pressed into service, holding the gap open.[19][22]

The Soviets transferred additional troops from newly formed armies into the region around Smolensk, namely the 29th, 30th, 28th, and 24th Armies. These newly built formations would, immediately upon arrival, start a heavy counter-attack against the German forces around the Smolensk area from 21 July on. This put a heavy strain on the overextended Panzer forces, which had to cover a large area around the perimeter. However, poor coordination and logistics on the part of the Soviets allowed the Germans to successfully defend against these offensive efforts, while continuing to close the encirclement. The Soviet attacks would last until 30 July, when the Germans finally repelled the last of them.[19][20]

Finally, on 27 July, the Germans were able to link up and close the pocket east of Smolensk, trapping large portions of 16th, 19th, and 20th Armies. Under the leadership of 20th Army, Soviet troops managed to break out of the pocket in a determined effort a few days later, assisted by the Soviet offensive efforts along the Smolensk front line. On 5 August von Bock reported that a total of 309,000 prisoners had been captured during the Battle of Smolensk at all. This number later increased to 350,000. Thus, only about 50,000 people from the encircled 16th and 20th armies escaped from the "cauldron" by 7 August.[23][24][25]

After the battle for encirclement near Smolensk ended on 5 August, the opponents drew different conclusions. The Soviet command was satisfied that they managed to restore the front line on the road to Moscow and save part of the encircled armies. It was decided to continue to strike at the opposing German forces, despite high losses. Thus, from their point of view, the battle was just beginning. In the following month, there were two major Soviet offensives: 6-24 August and 29 August – 12 September 1941.

On the part of the Germans, opinions were divided: von Bock believed that the battle was over, and after rest and replenishment, the troops of Army Group Center could continue their successful offensive against Moscow. However, Hitler was preoccupied with the stubborn defense of the Soviet Southwestern Front near Kiev and the increasing resistance of the Soviet troops of Zhukov and Timoshenko in the Moscow direction. On the other hand, Guderian's victory at Roslavl, on the right flank of Army Group Center, opened up the possibility of an attack to the south and a gigantic encirclement of Soviet troops near Kiev. Gradually OKH leaned towards Hitler's opinion. However, neither Bock nor Hitler planned an immediate offensive directly on Moscow, and the need to constantly repel Soviet strikes exhausted the troops. Von Bock wrote: "I was now forced to commit all of my combat-capable divisions from the army group’s reserve into combat…. We needed every man forward… In spite of huge losses… the enemy attacked daily in several sectors so that, up to this time, it has not been possible to regroup forces and bring up reserves."

Thus, in the next month after the elimination of the "cauldron" near Smolensk, von Bock's armies defended themselves in the center and attacked with limited forces on the flanks. In the south, Guderian won the battles near Gomel and Krichev, and in the north, Group Stumme captured Velikiye Luki and advanced further to the east to Andreapol. Most of the attacks of the Soviet troops were successfully repelled, but the Germans had to be withdrawn from the salient near Yelnya.[26][27]
