Kraslava While Kopyak was en route,
Germany invaded the Soviet Union on 22 June. The 112th had also been sent west from the Ural Military District, and when Kopyak took command on 27 June its units were defending positions near
Krāslava. On the morning of 1 July German units began attacking the 112th near Kraslava, and were repulsed in fighting that raged for most of the day. The 112th suffered significant casualties, and Kopyak had to commit a battalion to strengthen his right. By the morning of 2 July, Kopyak had brought up to Kraslava six of his nine rifle battalions and two of three divisional artillery battalions. His remaining forces were defending the line up to the city of
Drissa. The German units resumed the attack that morning, but the defenses of the 112th managed to hold again. However,
Dmitry Lelyushenko's
21st Mechanized Corps defending to the 112th's right began retreating to the northwest, exposing Kopyak's flank. Lelyushenko failed to inform Kopyak and it was not until 18:00 that day that the 112th's command found out. Kopyak realized the danger and ordered a retreat. In an hour the regiments began to draw off their troops to a new line east of Kraslava, abandoning the city by midnight. Army commander
Filipp Yershakov ordered the 112th to retreat further but the division did not receive the order. The fighting continued on 3 July and by the evening the dwindling forces of the 112th were no longer able to hold the line. Its defenses broken, the division retreated to the northeast towards the Sarjanka river under the over of darkness.
Nevel pocket Reestablishing defenses on the Sarjanka, the division came under infantry attack again on 7 July. Later that day, Kopyak concluded that the German concentration at the mouth of the Sarjanka was the main threat to the defense, and that night he reinforced the regiment defending there with two more battalions. However, the German attack on 8 July came against the 416th Regiment on the division's right, at
Lake Osveya. The attack drove a wedge into the Soviet positions and threatened the rear of the division. To remedy the situation, Kopyak went to the area of the fighting and threw two battalions into a counterattack, which halted the German advance at the cost of significant casualties. The right remained the most threatened sector of the division and Kopyak concentrated almost all of his reserves there. The division was driven back by tank-supported German attacks on 9 July, having lost 40 percent of its personnel and almost all its equipment and horses. During 11 July the division marched east towards the line of the Nishcha river and Yukhovichi, coming under periodic German air attack while conducting
rearguard actions as the
Battle of Smolensk began. Kopyak formed mobile detachments of company strength to cover the division's flanks. While the division retreated, the city of
Polotsk fell on 15 July, trapping the 51st Rifle Corps in the
Nevel pocket. By 16 July the remnants of the division reached the
sovkhoz of Repishche, suffering from a lack of ammunition, shells and provisions. The 51st Rifle Corps continued to retreat east on 17 July, cut off from the rest of the 22nd Army. With ammunition, fuel and provisions almost exhausted, corps commander General Akim Markov ordered a breakout. On the night of 19–20 July Kopyak's 112th attempted to break out through the Pustoshka–Nevel highway northeast of Nevel, but repeated attempts failed with heavy losses. The German troops responded with their own attacks and broke through to the division command post, only being stopped by a hastily organized counterattack. Most of the survivors of the division remained encircled and dispersed into small groups. Late on 21 July, due to the failure of the attempts of the previous two days, Kopyak decided to change the direction of the breakout attack to the south, towards Pogrebishche. He ordered the destruction of heavy equipment, with the soldiers left with only what they could carry out themselves and artillery that could be drawn by horses. However, Markov countermanded Kopyak's change of plans and the 112th had to regroup in the dark after it had already begun movement, creating confusion and noise that attracted German artillery fire. The remnants of the division took cover in a small forest, and a general attack by the remaining combat-capable units of the corps commenced hours later. However, this met with a similar lack of success. Scraping together survivors, Kopyak personally led his soldiers into the attack in the area of the Kuznetsovo forest in the predawn hours of 22 July. In one attack he was wounded and lay in a ditch for several hours, not having the strength to climb to the highway on his own. At night Kopyak managed to get up and returned to his command post in the Kuznetsovo forest. By the morning of 23 July, the encircled units of the 51st Corps had disintegrated and Kopyak and other commanders formed detachments of 200 to 250 men out of soldiers from all three divisions of the corps mixed together. Continuing to attack to the south, the Soviet breakout attempts resumed. Kopyak's detachment reached Soviet lines on 25 July in the region of Lake Dvinye. The remnants of the 112th were consolidated into the 112th Rifle Regiment, having retained their banner. Kopyak was wounded again in fighting in the region of Sosykino,
Kalinin Oblast on 22 August, after which he was treated in a hospital from 2 September to 6 November. Kopyak's reputation as a commander was strengthened by his performance in the Nevel pocket, as 51st Rifle Corps chief of staff Kuzma Sazonov reported that he wasn't "sitting somewhere in a dugout, but was where the fighting was the hottest." Kopyak took command of the new
140th Rifle Division, forming in the
Moscow Military District, on 21 December. He was promoted to major general on 3 May 1942. In May the division was assigned to the
24th Army of the
Southern Front. From 8 June it fought as part of the
9th Army, repulsing the German advance in
Case Blue in the Donbass and the
Great Bend of the Don, during the
Voronezh–Voroshilovgrad and Donbass defensive operations. In these intense battles Kopyak's division sustained heavy losses, and he was reported missing, presumed killed, in July. The 140th had only 85 personnel left by late July. == Decorations ==
