Hube had ordered all service units south of the Dniester to withdraw away from the main Red Army penetration which were taking place to the south on the 2nd Ukrainian Front's 40th Army front. Zhukov believed Hube would attempt to breakout to the south. To prevent this, he stripped units from the encircling forces and sent them to reinforce the south side of the pocket. Hube organizes move west Hans-Valentin Hube, the commander of the 1st Panzer Army, now ordered the pocket to be reduced in size, shortening the position's lines to increase defence density. As the 1st Ukrainian Front prepared to complete the encirclement Hube requested the authorization to use mobile defence tactics, a request which was quickly denied. However, once the encirclement was complete, the situation changed. Manstein had been arguing with Hitler for the trapped Army to be allowed to attempt a breakout, and for a relief force to be sent to assist them. With the loss of the entire Panzer army in the balance, Hitler finally gave in and ordered Hube to attempt a breakout. Though supplies were still being brought in, they were insufficient to maintain the Army's fighting strength. Moving west would mean fighting through the Soviet armoured forces that created the breach and crossing a number of rivers. Hube preferred to head south, over the Dniester. Manstein believed that this is what the Soviet command expected, and would be the most heavily resisted line of escape. Also, such a move would push the 1st Panzer Army into Romania, making defending the southern Ukraine sector quite difficult. The Hungarian VII Corps was holding a sector of the front to the west of the Kamianets-Podilskyi pocket. Manstein ordered Hube to break out to this area. The threat of panic among his troops within the pocket was a grave concern. As a means of maintaining control and simplifying the chain of command, Hube consolidated his forces into provisional corps groups. Each corps group, within its zone, was to be responsible for both the conduct of the attack to the west and the rear guard action in the east. The armored divisions of each corps group were to spearhead the army's attack, while the infantry divisions covered the rear. Two columns would fight their way west. The northern column was Korpsgruppe von der Chevallerie under command of Kurt von der Chevallerie and the south
