During the summer, when Germany was producing approximately 500 tanks a month, General Haider had told Hitler that the Soviet Union was producing 1,200 a month. The Führer had slammed the table and said that it was simply not possible. Yet even this figure was far too low. In 1942, Soviet tank production was rising from 11,000 during the first six months to 13,600 during the second half of the year, an average of over 2,200 a month. Aircraft production was also increasing from 9,600 during the first six months of the year, to 15,800 for the second.
The very suggestion that the Soviet Union, deprived of major industrial regions, could outproduce the Reich, filled Hitler with angry disbelief. Nazi leaders had always refused to acknowledge the strength of Russian patriotic feeling. They also underestimated the ruthless programme of evacuation of industry to the Urals and the militarization of the workforce. Over 1,500 factories had been evacuated from the western regions of the Soviet Union to behind the Volga, particularly the Urals, and reassembled by armies of technicians slaving through the winter. Few factories had any heating. Many had no windows at first, or proper roofing. Once the production lines started, they never stopped, unless halted by breakdowns, power failures, or shortages of particular parts. Manpower posed less of a problem. The Soviet authorities simply drafted in new populations of workers. Soviet bureaucracy wasted the time and talents of its civilian people, and squandered their lives in industrial accidents, with as much indifference for the individual as military planners showed towards their soldiers, yet the collective sacrifice—both forced and willing at the same time—represented a terrifyingly impressive achievement.
At a time when Hitler still refused to countenance the idea of German women in factories, Soviet production depended on the mass mobilization of mothers and daughters. Tens of thousands of dungareed women—‘fighters in overalls’—swinging tank turrets on hoists down production lines, or bent over lathes, believed passionately in what they were doing to help the men. Posters never ceased to remind them of their role: ‘What was Your Help to the Front?’
Chelyabinsk, the great centre of war industries in the Urals, became known as Tankograd. Soon, tank-training schools were established near the factories. The Party organized links between workers and regiments, while factories made collections to pay for more tanks. A tank gunner called Minakov composed a rhyme which seized the imagination of the Ural production lines:
Somebody later suggested that production-line workers should form the First Ural volunteer tank regiment. The organizers claimed to have received, within thirty-six hours of putting up the first poster, ‘4,363 applications to join the tank regiment, of which 1,253 Were from women’.
Even the slave-labour camps devoted to munitions production achieved a far higher output than their equivalents in Germany. There were also far fewer cases of sabotage. Gulag prisoners still believed in defeating the invader.
Allied aid is seldom mentioned in Soviet accounts, for reasons of propaganda, but its contribution towards keeping the Red Army fighting in the autumn of 1942 should not be overlooked. Stalin complained to Zhukov about the quality of the Hurricane fighters offered by Churchill, and the British and American tanks provided did not compare to the T-34. Consignments of British ammunition boots and greatcoats were just as unpopular with Soviet soldiers, because of their uselessness for winter warfare. But American vehicles—especially Ford, Willys and Studebaker trucks and jeeps—and food, whether the millions of tons of wheat in white sacks stamped with the American eagle and cans of Spam or corned beef from Chicago, made a huge, yet unacknowledged, difference to the Soviet Union’s ability to resist.
Zhukov knew the importance of having the right commanders for mechanized warfare. At the end of September, he persuaded Stalin to appoint General Konstantin Rokossovsky, a former victim of Beria’s NKVD, commander of the Don Front, which stretched from the northern tip of Stalingrad westwards to Kletskaya, just beyond the great Don bend. At the same time Lieutenant-General Nikolay Vatutin was put in charge of the new South-Western Front on Rokossovsky’s right flank, which faced the Third Romanian Army.
On 17 October, Don Front headquarters gave the order that all civilians ‘within fifteen miles of the front line’ must be evacuated by 29 October. Apart from security considerations, the military authorities wanted to be able to hide troops in villages by day, during their approach marches. It was a considerable operation, since the evacuees would be taking ‘their own cattle, sheep, pigs and hens and food for a month’. The cows were to act as draught animals, and all collective-farm tractors, combine harvesters and other valuable machinery were to be withdrawn. Several thousand civilians were drafted into a construction corps over 100,000 strong, repairing roads and bridges along the Saratov–Kamyshin–Stalingrad route and all others leading to the front.
From the newly laid Saratov–Astrakhan railroad, lines diverted to railheads in the steppe where the Stavka reserves would detrain, well to the rear, before proceeding to concentration areas behind the front. The strain on the Soviet railways system, moving 1,300 wagons a day to the three fronts, was immense. Confusion was inevitable. One division was left packed in troop trains for nearly two and a half months on sidings in Uzbekistan.
The plan for Operation Uranus was simple, yet daringly ambitious in its scope. The main assault, over a hundred miles west of Stalingrad, would be launched south-eastwards from the Serafimovich bridgehead, a forty-mile-long stretch south of the Don which the Romanian Third Army had not had the strength to occupy. This point of attack was so far to the rear of the Sixth Army that German mechanized forces in and around Stalingrad would not be able to get back in time to make a difference. Meanwhile, an inner strike would cut down from another bridgehead south of the Don at Kletskaya, then attack the rear of Strecker’s XI Army Corps stretched across the greater and the lesser Don bends. Finally, from south of Stalingrad, another armoured thrust would attack north-westwards to meet up with the main assault around Kalach. This would mark the encirclement of Paulus’s Sixth Army and part of Hoth’s Fourth Panzer Army. Altogether some 60 per cent of the whole tank strength of the Red Army was allocated to Operation Uranus.
Soviet security proved better than one might have expected, considering the number of Red Army prisoners and deserters passing through Wehrmacht hands. German intelligence had failed during the summer of 1942 to identify the creation of five new tank armies (each roughly the equivalent of a panzer corps) and fifteen tank corps (each the equivalent of a strong panzer division). As the moment of retribution approached, the Red Army paid great attention to maskirovka, a term covering deception, camouflage and operational security, by greatly reducing the quantity of radio traffic. Orders were given in person and not written down. Active deception measures included stepping up activity around Moscow. The Germans identified the Rzhev salient as the most likely area for a Soviet offensive in November. Meanwhile in the south, front-line divisions along the sectors vital for Operation Uranus were ordered to construct defence lines, purely for the benefit of German air reconnaissance, while the Voronezh Front, which was not involved, received orders to prepare bridging equipment and boats, as if for an offensive.
Troop activity in other sectors was concealed by the construction of defences, which gave the opposite impression to plans for an offensive. The approach marches of formations for Operation Uranus were made at night, with troops hiding up during the day, a difficult task on the bare steppe, but Red Army camouflage techniques were remarkably effective. No fewer than seventeen false bridges were constructed over the Don to attract the Luftwaffe’s attention away from the five real ones, over which crossed the 5th Tank Army, the 4th Tank Corps, two cavalry corps and numerous rifle divisions.
