To be closer to the southern front, Hitler moved his headquarters on
Away from the supper soliloquies, however, tension mounted once more between Hitler and his military leaders. The military advance continued to make ground. But the numbers of Soviet prisoners captured steadily diminished. This was endlessly discussed at FHQ.199 Hitler’s military advisers were worried. They took it that the Soviets were pulling back their forces in preparation for a big counter-offensive, probably on the Volga, in the Stalingrad region.200 Halder had warned as early as 12 July of concern at the front that the enemy, recognizing German envelopment tactics, was avoiding direct fight and withdrawing to the south.201 Hitler’s view was, however, that the Red Army was close to the end of its tether. He pressed all the more for a speedy advance.202
His impulsive, though sometimes — as the Voronezh episode had shown — unclear or ambiguous command-style caused constant difficulties for the operational planners. But the essential problem was more far-reaching. Hitler felt compelled by two imperatives: time, and material resources. The offensive had to be completed before the might of Allied resources came fully into play. And possession of the Caucasian oil-fields would, in his view, both be decisive in bringing the war in the east to a successful conclusion, and provide the necessary platform to continue a lengthy war against the Anglo-Saxon powers.203 If this oil were not gained, Hitler had said, the war would be lost for Germany within three months.204 Following his own logic, Hitler had, therefore, no choice but to stake everything on the ambitious strike to the Caucasus in a victorious summer offensive.205 Even if some sceptical voices could be heard, Halder and the professionals in Army High Command had favoured the offensive. But the gap, already opened up the previous summer, between them and the dictator was rapidly widening. What Hitler saw as the negativity, pessimism, and timidity of Army High Command’s traditional approaches drove him into paroxysms of rage. Army planners for their part had cold feet about what increasingly seemed to them a reckless gamble carried out by dilettante methods, more and more likely to end in disaster. But they could not now pull out of the strategy which they had been party to implementing. A catastrophe at Stalingrad was the heavy price that would soon be paid. The German war effort had set in train its own self-destructive dynamic.
