In June 1944, the 1st Belarusian Front launched a centripetal assault on the enemy in the general direction of Bobruisk from the areas north of Rogachev and south of Parich, encircling and annihilating the enemy's Bobruisk army. The Ruisk Group then attacked Pukhovich and Slutsk. On June 24, the attack was launched after 2 hours and 5 minutes of artillery preparations and a short period of aviation fire preparations in the southern section. On the first day, the 3rd and 48th Group Armies only captured two German trenches; the 65th and 28th Group Armies broke through the enemy's defense front for 30 kilometers and 5 to 10 kilometers in depth; the 1st Tank Army entered the breach and pushed forward. 20 kilometers. The next day, the cavalry mechanized group that entered the battle attacked northwest and advanced deeply into the German defenses. By June 26, it reached the Putich River near Glusk and successfully crossed in some areas. On the night of June 26, the 1st Tank Corps successfully maneuvered and cut off the roads heading west and northwest from Bobruisk. The 16th Air Force Group Army carried out continuous assaults on the retreating enemy and the crossing of the Berezina River, supporting the offensive operations of the ground forces with powerful firepower. On the second day of the offensive, the 9th Tank Army entered the battle in the 3rd Army area and quickly advanced forward. On the morning of June 27, it began to circle back to Bobruisk from the north and meet up with the 1st Tank Army. This led to the encirclement of an enemy group totaling 40,000 people in the southeast area of ??Bobruisk. Part of the front forces cleared the besieged groups, while the main force continued to attack Minsk and Slutsk. The 3rd and 28th Group Armies followed up with the rapid troops and advanced towards the encircled external front, while the 48th and 65th Group Armies advanced towards the encircled internal front. On June 27, there were only two tank corps units covering the northwest section of the inner front because the infantry corps had not yet arrived. It was at this area that the besieged enemy troops began to prepare to break out of the encirclement, attempting to rendezvous with the troops of the 4th Group Army. In this case, the front commander cleverly used front aviation. The 526 aircraft of the 16th Air Force Group Army, in a group of 25 to 30 aircraft, carried out continuous attacks on the encircled enemy forces for one and a half hours, causing the German army groups preparing to break out to collapse and suffer heavy losses. . On June 28, the 48th Group Army completely destroyed the encircled enemy. On June 29, the city of Bobruisk was liberated. After six days of offensive, the Soviet army completely smashed the German army groups defending Vitebsk and Bobruisk, and also broke through the enemy's defense front in the direction of Mogilev. After suffering a huge defeat, the German army retreated from the wide front from the West Dvina River to the Pripyat River. The Soviet army advanced 100 to 150 kilometers, and then launched an attack in the direction of Spripo Ventsyany, Minsk and Sluts, chasing the fleeing enemy in order to encircle the German 4th Army in the area east of Minsk The main force to prevent the German army from establishing a continuous defense line in Belarus.
