The division remained in much the same positions at the base of the former salient during the operational pause in the spring and early summer of the year. Just prior to the start of the summer offensive the division joined the
84th Rifle Corps, still in 39th Army, along with the
134th and
234th Rifle Divisions. The Corps was commanded by Lt. Gen. S. A. Knyazkov. Operation
Suvorov began on August 7, but Kalinin Front's part in it, in the direction of Dukhovshchina, was limited to diversionary activity until August 13. It began its main attack at 0730 hours, attacking
XXVII Army Corps 8 km northeast of Dukhovshchina, led by five divisions of
83rd Rifle Corps and
2nd Guards Rifle Corps, backed by two tank brigades, two tank regiments, and two sapper brigades.
43rd Army provided support on the right. XXVII Corps was assigned a 40 km-wide front held by three divisions and a fourth in reserve. All of these were at roughly half their authorized strength, but their
Barbarossa-Stellung line consisted of three full lines of trenches sited on heavily wooded high ground.
Operation Suvorov The ammunition supply limited the Front commander, Col. Gen.
A. I. Yeryomenko, to a 35-minute artillery preparation, which mostly failed to suppress the defenses. In the first hours, 2nd Guards Corps was able to penetrate the first trench line south of Spas-Ugly and overrun a German battalion. But overall the Army's shock groups gained at most 1,500m before being halted by counterattacks.
PaK 40 antitank guns destroyed or disabled 45 of the supporting tanks in the first two days of battle. On the second day, heavy air attacks disrupted several of 39th Army's formations, and ground reinforcements began arriving, including a battalion of
Nashorn tank destroyers. Finally, the
25th Panzergrenadier Division arrived, which allowed XXVII Corps to stabilize its line. 39th Army gained about 3 km of ground in four days of heavy fighting, at substantial cost, without reaching any objectives. Kalinin Front had taken some 10,000 casualties to this point, but German casualties had also been heavy, especially to the infantry. On August 21 the overall offensive by both Western and Kalinin Fronts was suspended due to losses, supply shortages, and a period of rainy weather. The 18th Panzer Division was transferred to backstop XXVII Corps, but it had only 1,200 infantry and 13 tanks. Kalinin Front resumed the offensive on August 25. 39th Army was reinforced with the
5th Guards Rifle Corps, but this force was only able to advance 1,000m on a 3 km front in five days of fighting. Yeryomenko was stymied. He wrote in his memoirs:Despite this, he was ordered to go on attacking. While Western Front made more substantial gains,
Suvorov was again suspended on September 7. When it resumed on September 14, XXVII Corps was attempting to hold a sector 81 km-wide with five divisions containing just 10,000 troops in total. The Corps commander expected the main thrust to come from east of Dukhovshchina, where he deployed the 25th Panzergrenadiers backed by
1st SS Infantry Brigade. Yeryomenko shook up his command, in part by replacing General Zygin with Lt. Gen.
N. E. Berzarin. Having learned of the arrival of 1st SS he briefly shifted his main effort to his 43rd Army to the northwest, where the German lines were even more thinly held, and scored a minor success. After a 20-minute artillery preparation the 39th Army struck near Spas-Ugly with four divisions and smashed a German regiment, breaching the line. By 1000 hours the conditions were favorable for Yeryomenko to commit his mobile forces, which collapsed and routed what remained of
52nd Infantry Division. With Soviet armor roaming in its rear the XXVII Corps was forced to commit the weak 18th Panzer, which simply did not have the strength to deal with the crisis. On September 15, Berzarin expanded his penetration and mopped up bypassed pockets. After hanging on as long as possible XXVII Corps began to retreat to the
Hubertus-I-Stellung to the rear. As front-line resistance evaporated the two Armies of Kalinin Front took up the pursuit. The following morning the 2nd Guards Corps met 84th Corps at Klevtsi, 11 km north of Dukhovshchina, but they failed to trap the
197th Infantry Division. 2nd Guards Corps and the Dremov mobile group now pushed south toward Dukhovshchina against weak rearguards. It was now clear that
Hubertus-I was untenable, and the town was evacuated overnight on September 16/17. Smolensk was liberated by units of Western Front on September 25, as Army Group Center fell back to the promised refuge of the
Panther Line behind the Dniepr River.
Vitebsk Offensive By the beginning of October, 39th Army, still in Kalinin (as of October 20
1st Baltic) Front, was located south of
Velizh and was facing elements of
VI Army Corps of 3rd Panzer Army. Following the liberation of Smolensk the next obvious objective was the Belarusian city of Vitebsk, which was intended to be taken by October 10. General Berzarin was to conduct the Front's main attack through
Rudnya and Lyozna. He chose to deploy his 84th and 5th Guards Corps, backed by a small mobile group, along the SmolenskVitebsk highway; the 84th's four divisions (
219th,
184th, 158th, and 134th) were backed by the 46th Mechanized Brigade and the 158th was in second echelon. Rudnya was liberated by 5th Guards Corps on September 29 and on October 3 the 134th and 184th Divisions breached the defenses northeast of
Mikulino, forcing a German withdrawal on October 6 to new positions north and south of Lyozna. In heavy fighting through October 7–8 the 84th Corps cleared the town with help from the mobile group and the 158th received a battle honor:The remaining defenders fell back to a new line 10 km to the west late on October 9, which was reached by the pursuit on the 12th. Given the attrition suffered in the nine previous days the offensive was paused for regrouping. The 39th and 43rd Armies renewed the offensive on October 15 with a series of local attacks. 158th, 32nd, and 184th Divisions struck the
246th Infantry Division (
LIII Army Corps) west of Lyozna without any success. Further efforts by both 84th and 5th Guards Corps on October 18 yielded the same lack of results. Yeryomenko stated in a telegram to the
STAVKA on October 19:Nevertheless, the
STAVKA would continue to try to crack the Vitebsk defenses. On October 25, Col.
Luka Herasymovich Basanets became the 158th's deputy commander, a post he would hold until May 24, 1944.
Polotsk-Vitebsk Offensive The 1st and
2nd Baltic Fronts began new operations in early November; the objective for 1st Baltic was first to take Vitebsk and then to advance toward
Polotsk. The 39th and 43rd Armies were positioned primarily to the north of the SmolenskVitebsk railroad and highway against the defending VI Army Corps. When the assault began on November 8 the 39th Army had the 84th and the 5th Guards Corps deployed abreast, supported by a composite mobile corps made up of three mechanized and tank brigades under command of Colonel Dremov. Despite the attacking forces being eroded to about half their authorized strengths they still enjoyed a fivefold superiority in infantry and an absolute superiority in armor and artillery. On the first day the 184th Division and 124th Rifle Brigade were repulsed by the 246th Infantry Division, but this was intended as a diversion. The next morning the Army's main forces attacked and ripped through the defenses of the 206th Infantry Division just north of the highway. This joint assault on November 9 by the 39th and 43rd Armies breached the German line along a 10 km-wide front and by evening the lead elements of the attacking force had reached Poddube, just 10 km east of the defense lines around Vitebsk proper. The 206th Infantry's front was a shambles by nightfall and the
14th Infantry Division's right flank was both turned and wide open. While the 43rd Army's advance was largely contained at Poddube on November 11 the 39th managed to continue another 5 km along the highway as far as Karamidy and the banks of the Losonina River, 10 km east of Vitebsk. General Berzarin now committed the Dremov Group to combat which led to a complex battle with elements of the 18th Panzer Division and battlegroups of the 206th and 246th Infantry. By November 17 the German forces were able to restore a fairly continuous front and the Soviet assault expired in exhaustion.
Vitebsk (Gorodok) Offensive On December 8 the
STAVKA directed the new commander of 1st Baltic Front, Army Gen.
I. K. Bagramyan, to go over to the defense so his armies could regroup and refit prior to another offensive to take Vitebsk as well as the town of
Haradok to the north. The forces of his Front, including the 158th, were by now seriously under strength from near-continuous fighting since early October. The new offensive on Vitebsk would also involve the
33rd Army of Western Front and would begin on December 19. At the start of the offensive the combined forces of 43rd and 39th Armies struck the defenses of 14th Infantry Division. According to German records eight rifle divisions, one rifle brigade and two tank units participated in the initial assault on a 16 km-wide sector from Borok northeast to Kasenki, south of the VitebskSurazh road. General Berzarin had deployed his 5th Guards and
1st Rifle Corps, soon reinforced with 84th Corps and several separate formations, on the BorokGoriane sector. Overall the two armies drove the defenders back up to 3 km on an 8 km-wide front by day's end on December 19 and almost reached the VitebskSurazh road. The next day the second echelon divisions were committed to develop the attack; these gained another 2 km in heavy fighting but were still unable to cross the road. The 14th Infantry committed all its reserves and was reinforced with one regiment of the 197th Infantry transferred from the Orsha sector. The battle raged until December 23 by which time the Soviet forces had reached the road on a 10 km sector from Piatiletna to Kasenki.
Third Vitebsk Offensive By this time the 2nd Baltic Front was about to liberate Haradok and the German position at Vitebsk was becoming pocketed on three sides. The
STAVKA believed that the forces it had assembled were sufficient to pinch off the salient and take the city. Western Front's 33rd Army was heavily reinforced to lead the new effort with the 39th Army's 5th Guards and 84th Corps concentrated on and south of the SmolenskVitebsk highway; although the divisions of these Corps had been severely weakened in previous attacks they faced only a single regiment of the 206th Infantry. The assault began on December 23 and 91st Guards was initially deployed in the Corps' reserve. By December 26, 5th Guards Corps had advanced a mere 2–3 km, leading to a caustic telegram from the
STAVKA to the 1st Baltic Front, demanding greater progress. Reserves were now committed to the fighting but despite this 39th Army only managed to gain another 1–2 km by December 28 before stalling completely, while 33rd Army soldiered on until January 6, 1944. General Bezuglyi left the division on January 2 and a week later took over 5th Guards Corps. He would be promoted to the rank of lieutenant general on July 15 and would retire in June 1953. He was briefly replaced by Col. Daniil Sergeevich Kondratenko until February 10 when he stepped aside for Col. Demyan Ilich Goncharov, who had previously served as deputy commander of
360th Rifle Division and chief of staff of
91st Rifle Corps. The offensive was renewed on January 8. 5th Guards Corps formed 39th Army's shock group on a 6 km-wide between the SmolenskVitebsk road and the village of Vaskova, again facing the 206th Infantry Division. 84th Corps was on its right, with the 158th in its second echelon. By now these divisions were at less than 40 percent of authorized strength. Although the German forces were similarly weakened, 5th Guards Corps' attack floundered after an advance of only about 1000m. Although the 33rd and
5th Armies to the south made greater progress, it was at a heavy cost, and the offensive was finally shut down late in the month.
Fourth and Fifth Vitebsk Offensive Later in January the 158th, along with its Corps and Army, was transferred to Western Front, which was commanded by Army Gen.
V. D. Sokolovskii. The
STAVKA now ordered the Front to change the axis of its attacks northward toward Vitebsk itself. Berzarin once again would attack along and south of the SmolenskVitebsk road against the 206th Infantry. He chose to configure his Army with 84th Corps in first echelon and 5th Guards Corps in second. The 84th, now led by Maj. Gen. E. V. Dobrovolskii, would continue to guard the sector north from the highway to Poddube with the
262nd Rifle Division while the 158th and 134th Divisions would attack west to Ugliane with 28th Tank Brigade in support and 32nd Rifle Division in second echelon; this objective was just 12 km southeast of the center of Vitebsk. The offensive began with an intense artillery preparation at dawn on February 3, but this failed to silence many German strongpoints, artillery and mortar positions. The 158th and 134th made scarcely a dent on the 206th and they soon fell back to their start lines with heavy losses. While this effort was suspended the 33rd Army had greater success and the offensive continued for five more days, bending but not breaking the defense. Yet another attempt to take the city was set to begin on February 29. By this time the 158th and 134th were facing the 246th Infantry in the Babinichi area, while the 262nd and the 5th Guards Corps opposed the 206th. The 33rd Army would again carry the main weight; once it took
Astrowna most of 39th Army were to attack from the Poddube region. Just as this was to begin the commander of 3rd Panzer Army, Col. Gen.
G.-H. Reinhardt, disrupted the entire plan by shortening his defensive line around Vitebsk. The 246th and 206th pulled back to a new line from Avdeevichi on the Dvina south across the SmolenskVitebsk road to Shelegova and allowed the creation of reserves. From the perspective of Sokolovskii the entire plan for 39th Army was compromised. The offensive went ahead with mixed results, and early on March 5 the 158th attacked in cooperation with the
334th Rifle Division of the adjacent 43rd Army against the 246th Infantry on a 6 km-wide sector from the Dvina south to Babinichi. This forced a German withdrawal to new lines from Zakharova to Senkova, some 2 km west of Babinchi. However, this marked the culmination of the offensive, as the spring mud began to set in. Western Front had lost 2,650 killed and 9,205 wounded in this latest attack, as well as most of its remaining tanks. By this time the
STAVKA had run out of faith in Sokolovskii. He was removed from his command on April 15, and on April 24 his Front was split into 2nd and 3rd Belorussian Fronts, with 84th Corps and 39th Army moving to become the north flank of the latter. ==Operation Bagration==
