The frustrations provoked quarrels between commanders. A majority

• General Heinz Guderian was the most outspoken - despaired of Hitler's diversions. Moscow was not only the capital of the Soviet Union, they argued, it was also a major centre for communications and the armaments industry. An attack on it would also draw in surviving Soviet armies to their final destruction. The Führer, however, kept his generals in order by exploiting their rivalries and disagreements. He told them that they knew nothing of economic matters. Leningrad and the Baltic had to be secured to protect essential trade with Sweden, while the agriculture of the Ukraine was vital to Germany. Yet his instinct to avoid the road to Moscow was partly a superstitious avoidance of Napoleon's footsteps.

Army Group Centre, having secured Smolensk and encircled the Soviet armies beyond it at the end of July, was ordered to halt. Hitler sent most of Hoth's panzer group northwards to help the attack on Leningrad, while 'Panzerarmee Guderian' (the new designation was a typical Hitlerian sop to a disgruntled but necessary general) was diverted southwards to act as the upper jaw of the great Kiev encirclement.

Hitler changed his mind again early in September when he at last agreed to Operation Typhoon, the advance on Moscow. Yet more time was lost because Hoth's panzer divisions were still engaged in the outskirts of Leningrad. The forces for Operation Typhoon were not finally ready until the very end of September. Moscow lay just over 200 miles away from where Army Group Centre had been halted, and little time remained before the period of autumn mud, and then winter. When General Friedrich Paulus, Haider's chief planner for Barbarossa, had raised the question of winter warfare earlier, Hitler had forbidden any mention of the subject.
