On the morning of 1 August, the commands of the 6th and 12th armies (from 28 July, the remnants of the 6th and 12th armies and the 2nd Mechanized Corps were combined in Ponedelin Group) sent a joint communication to the command of the Southern Front, with a copy sent to Stalin:
The situation has become critical.
The encirclement of the 6th and 12th armies is completed.
There is a direct threat of the disintegration of the combined combat order of 6th and 12th armies <...> There are no reserves<...> There is no ammunition, the fuel is running out.

But the commander of the Southern Front, Tyulenev, assured Stalin that the situation would be restored by a blow towards Ponedelin Group of the fresh 223rd Rifle Division from the northeast, and the units of 18th Army from the south, while denying any supply difficulties.

On 1 August, the Soviet 18th Army from the south attempted to join the Ponedelin group.
But the divisions on the right flank of the XXXXIX Mountain Corps repelled the attack of the Soviet 17th Rifle Corps, and by evening the 18th Army was attacked by units of the LII Army Corps and Hungarian Mobile Corps.
The commander of the 18th Army gave the order to retreat to Pervomaysk.
At the same time, the attacks of the XXXXIX Mountain Corps against the Ponedelin group distracted the Soviet units and allowed the 1st Mountain Division to move even further to the east.

The just formed and inexperienced 223rd Rifle Division, while preparing for an attack fell under the sudden blow of the 14th Panzer Division, and was quickly defeated.
A breakthrough towards Ponedelin Group from the north-east was foiled.
The command of the Southern Front continued to believe that only the "leaked" groups of the enemy are acting in this direction, while the main forces of the 1st Panzer Group have already entered the breakthrough, spreading to the south and southeast.

On 2 August, the units of the 1st Mountain Division reached the Sinyuha River, where they joined the 9th Panzer Division of the XIV Motorized Corps.
At this time, other parts of the XXXXVIII and XIV Corps in heavy fighting repulsed all attempts of the Ponedelin Group to break through to the east and north-east.
The ring of encirclement was closed, but it was not yet strong.
The encirclement was reinforced the next day by a second joining, formed when the German 16th Panzer Division met the Hungarian Mobile Corps in Pervomaysk.
