Army Group South
The 6th and 17th Army broke Soviet defences on the Bug river and advanced east. The brunt of the fighting fell on Reichenau's 6th Army, which faced stiff Soviet resistence moving east. Two pockets have been formed, one at Kovel (8 divisions) and one major pocket at Lvov (at least 35 divisions).
It is important at this point to explain why 2/3s of Guderians Panzer Group 2 have been diverted South. Following the opening made by elements of the 6th Army and the advance of the 1st Panzer Group, recon and intelligence reports indicated a massive gap in Soviet defences near and south of the city of Tarnopol. The commander of the 1st Panzer Group, Generaloberst von Kleist requested extra units to make a dash for the Romanian border, ensuring the encirclement of a substantial ammount of Soviet armored formations in the South. After much discussion, the OKH ordered Guderian to divert a part of his units south. However the movement and operations of these units did not go very smoothly. In the case of the Kovel pocket, the lack of maps on the area around Manevichi, bad terrain and communication problems between units of the 1st Panzer Groups and units of the 2nd Panzer Group resulted in a poor screening of the pocket to the north east, where a gap has developed. In the following map, escape routes that the Soviets are likely to take have been marked in green.
In the case of the Lvov pocket, opeerations ran more smoothly due to better maps and terrain. The OKH believes that the pocket will hold till next week, and by that time the advancing infantry should be able to clear the Soviet defenders.
