German dead in the city
About 265,000 German, Romanian, and Italian soldiers,[63][page needed] the 369th (Croatian) Reinforced Infantry Regiment, and other volunteer subsidiary troops including some 40,000 Soviet volunteers fighting for the Germans (Beevor states that one quarter of the sixth army's frontline strength were HIWIs, as collaborationists recruited from the ranks of Soviet POWs were called)[citation needed][64] were surrounded. These Soviet HIWIs remained loyal, knowing the Soviet penalty for helping the Germans was summary execution. German strength in the pocket was about 210,000 according to strength breakdowns of the 20 field divisions (average size 9,000) and 100 battalion sized units of the Sixth Army on 19 November 1942. Inside the pocket (German: Kessel, literally "cauldron"), there were also around 10,000 Soviet civilians and several thousand Soviet soldiers the Germans had taken captive during the battle. Not all of the 6th Army was trapped; 50,000 soldiers were brushed aside outside the pocket. These belonged mostly to the other 2 divisions of the 6th Army between the Italian and Romanian Armies: the 62nd and 298th Infantry Divisions. Of the 210,000 Germans, 10,000 remained to fight on, 105,000 surrendered, 35,000 left by air and the remaining 60,000 died.
The Red Army units immediately formed two defensive fronts: a circumvallation facing inward and a contravallation facing outward. Field Marshal Erich von Manstein advised Hitler not to order the 6th Army to break out, stating that he could break through the Soviet lines and relieve the besieged 6th Army.[65] The American historians Williamson Murray and Alan Millet wrote that it was Manstein's message to Hitler on 24 November advising him that the 6th Army should not break out, along with Göring's statements that the Luftwaffe could supply Stalingrad that "... sealed the fate of the Sixth Army."[66] After 1945, Manstein claimed that he told Hitler that the 6th Army must break out.[67] The American historian Gerhard Weinberg wrote that Manstein distorted his record on the matter.[68] Manstein was tasked to conduct a relief operation, named Operation Winter Storm (Unternehmen Wintergewitter) against Stalingrad, which he thought was feasible if the 6th Army was temporarily supplied through the air.[69][70]
Adolf Hitler had declared in a public speech (in the Berlin Sportpalast) on 30 September 1942 that the German army would never leave the city. At a meeting shortly after the Soviet encirclement, German army chiefs pushed for an immediate breakout to a new line on the west of the Don, but Hitler was at his Bavarian retreat of Obersalzberg in Berchtesgaden with the head of the Luftwaffe, Hermann Göring. When asked by Hitler, Göring replied, after being convinced by Hans Jeschonnek,[6]:p.234 that the Luftwaffe could supply the 6th Army with an "air bridge." This would allow the Germans in the city to fight on temporarily while a relief force was assembled.[16]:926 A similar plan had been used a year earlier at the Demyansk Pocket, albeit on a much smaller scale: a corps at Demyansk rather than an entire army.
A Ju 52 approaching Stalingrad
The director of Luftflotte 4, Wolfram von Richthofen, tried to get this decision overturned. The forces under 6th Army were almost twice as large as a regular German army unit, plus there was also a corps of the 4th Panzer Army trapped in the pocket. The maximum 107 t (118 short tons) they could deliver a day—based on the number of available aircraft and with only the airfield at Pitomnik to land at—was far less than the minimum 750 t (830 short tons) needed.[6][Note 6] To supplement the limited number of Junkers Ju 52 transports, the Germans pressed other aircraft into the role, such as the Heinkel He 177 bomber (some bombers performed adequately—the Heinkel He 111 proved to be quite capable and was much faster than the Ju 52). General Richthofen informed Manstein on 27 November of the small transport capacity of the Luftwaffe and the impossibility of supplying 300 tons a day by air. Manstein now saw the enormous technical difficulties of a supply by air of these dimensions. The next day he made a six-page situation report to the general staff. Based on the information of the expert Richthofen, he declared that contrary to the example of the pocket of Demyansk the permanent supply by air would be impossible. If only a narrow link could be established to Sixth Army, he proposed that this should be used to pull it out from the encirclement, and said that the Luftwaffe should instead of supplies deliver only enough ammunition and fuel for a breakout attempt. He acknowledged the heavy moral sacrifice the giving up of Stalingrad means but this is made easier to bear by the conservation of the combat power of Sixth Army and the regaining of the initiative ..."[71] He ignored the limited mobility of the army and the difficulties of disengaging the Soviets. Hitler reiterated that Sixth Army would stay at Stalingrad and that the air bridge would supply it until the encirclement was broken by a new German offensive.
The Luftwaffe was able to deliver an average of 85 t (94 short tons) of supplies per day out of an air transport capacity of 106 t (117 short tons) per day. The most successful day, 19 December, delivered 262 t (289 short tons) of supplies in 154 flights.
In the early parts of the operation, fuel was shipped at a higher priority than food and ammunition because of a belief that there would be a breakout from the city.[21]:p.153 Transport aircraft also evacuated technical specialists and sick or wounded personnel from the besieged enclave. Sources differ on the number flown out: at least 25,000 to at most 35,000. Carell: 42,000, of which 5000 did not survive.
The center of Stalingrad after liberation
Initially, supply flights came in from the field at Tatsinskaya, called 'Tazi' by the German pilots. On 23 December, the Soviet 24th Tank Corps, commanded by Major-General Vasily Mikhaylovich Badanov, reached nearby Skassirskaya and in the early morning of 24 December, the tanks reached Tatsinskaya. Without any soldiers to defend the airfield, it was abandoned under heavy fire; in a little under an hour, 108 Ju 52s and 16 Ju 86s took off for Novocherkassk—leaving 72 Ju 52s and many other aircraft burning on the ground. A new base was established some 300 km (190 mi) from Stalingrad at Salsk, the additional distance would become another obstacle to the resupply efforts. Salsk was abandoned in turn by mid-January for a rough facility at Zverevo, near Shakhty. The field at Zverevo was attacked repeatedly on 18 January and a further 50 Ju 52s were destroyed. Winter weather conditions, technical failures, heavy Soviet anti-aircraft fire and fighter interceptions eventually led to the loss of 488 German aircraft.
In spite of the failure of the German offensive to reach 6th Army, the air supply operation continued under ever more difficult circumstances. The 6th Army slowly starved. Pilots were shocked to find the troops too exhausted and hungry to unload. Germans fought over the slightest scraps of bread. General Zeitzler, moved by their plight, began to limit himself to their slim rations at meal times. After a few weeks on such a diet, he had lost 12 kg (26 lb) and had become so emaciated that Hitler, annoyed, personally ordered him to start eating regular meals again.
The toll on the Transportgruppen was heavy. 160 aircraft were destroyed and 328 were heavily damaged (beyond repair). Some 266 Junkers Ju 52s were destroyed; one-third of the fleet's strength on the Eastern Front. The He 111 gruppen lost 165 aircraft in transport operations. Other losses included 42 Ju 86s, 9 Fw 200 Condors, 5 He 177 bombers and 1 Ju 290. The Luftwaffe also lost close to 1,000 highly experienced bomber crew personnel.[6]:p.310 So heavy were the Luftwaffe 's losses that four of Luftflotte 4's transport units (KGrzbV 700, KGrzbV 900, I./KGrzbV 1 and II./KGzbV 1) were "formally dissolved."[3]:p.122
