Battle of Stalingrad

During the defence of Stalingrad, the Red Army deployed five armies in and around the city (28th, 51st, 57th, 62nd and 64th Armies); and an additional nine armies in the encirclement counteroffensive[52] (24th, 65th, 66th Armies and 16th Air Army from the north as part of the Don Front offensive, and 1st Guards Army, 5th Tank, 21st Army, 2nd Air Army and 17th Air Army from the south as part of the Southwestern Front).

David Glantz indicated[53] that four hard-fought battles – collectively known as the Kotluban Operations – north of Stalingrad, where the Soviets made their greatest stand, decided Germany's fate before the Nazis ever set foot in the city itself, and were a turning point in the war. Beginning in late August, continuing in September and into October, the Soviets committed between two and four armies in hastily coordinated and poorly controlled attacks against the Germans' northern flank. The actions resulted in more than 200,000 Soviet Army casualties but did slow the German assault.

On 23 August the 6th Army reached the outskirts of Stalingrad in pursuit of the 62nd and 64th Armies, which had fallen back into the city. Kleist later said after the war:

The capture of Stalingrad was subsidiary to the main aim. It was only of importance as a convenient place, in the bottleneck between Don and the Volga, where we could block an attack on our flank by Russian forces coming from the east. At the start, Stalingrad was no more than a name on the map to us.[54]

The Soviets had enough warning of the German advance to ship grain, cattle, and railway cars across the Volga out of harm's way, but Stalin refused to evacuate the 400,000 civilian residents of Stalingrad. This "harvest victory" left the city short of food even before the German attack began. Before the Heer reached the city itself, the Luftwaffe had cut off shipping on the Volga, vital for bringing supplies into the city. Between 25 and 31 July, 32 Soviet ships were sunk, with another nine crippled.[55]

The battle began with the heavy bombing of the city by Generaloberst Wolfram von Richthofen's Luftflotte 4. Some 1,000 tons of bombs were dropped in 48 hours, more than in London at the height of the Blitz.[56] The exact number of civilians killed is unknown but was most likely very high. Around 40,000 civilians were taken to Germany as slave workers, some fled during battle and a small number were evacuated by the Soviets, but by February 1943 only 10,000 to 60,000 civilians were still alive. Much of the city was smashed to rubble, although some factories continued production while workers joined in the fighting. The Stalingrad Tractor Factory continued to turn out T-34 tanks up until German troops burst into the plant. The 369th (Croatian) Reinforced Infantry Regiment was the only non-German unit[57] selected by the Wehrmacht to enter Stalingrad city during assault operations. It fought as part of the 100th Jäger Division.

Stalin rushed all available troops to the east bank of the Volga, some from as far away as Siberia. Regular river ferries were quickly destroyed by the Luftwaffe, which then targeted troop barges being towed slowly across by tugs.[49] It has been said that Stalin prevented civilians from leaving the city in the belief that their presence would encourage greater resistance from the city's defenders.[58] Civilians, including women and children, were put to work building trenchworks and protective fortifications. A massive German air raid on 23 August caused a firestorm, killing hundreds and turning Stalingrad into a vast landscape of rubble and burnt ruins. Ninety percent of the living space in the Voroshilovskiy area was destroyed. Between 23 and 26 August, Soviet reports indicate 955 people were killed and another 1,181 wounded as a result of the bombing.[59] Casualties were estimated to have been 40,000,[60] though they were likely exaggerated,[61] and after 25 August the Soviets did not record any civilian and military casualties as a result of air raids.[Note 3]

Soviets preparing to ward off a German assault in Stalingrad's suburbs

The Soviet Air Force, the Voyenno-Vozdushnye Sily (VVS), was swept aside by the Luftwaffe. The VVS bases in the immediate area lost 201 aircraft between 23 and 31 August, and despite meagre reinforcements of some 100 aircraft in August, it was left with just 192 serviceable aircraft, 57 of which were fighters.[62] The Soviets continued to pour aerial reinforcements into the Stalingrad area in late September, but continued to suffer appalling losses; the Luftwaffe had complete control of the skies.

The burden of the initial defence of the city fell on the 1077th Anti-Aircraft Regiment,[58] a unit made up mainly of young female volunteers who had no training for engaging ground targets. Despite this, and with no support available from other units, the AA gunners stayed at their posts and took on the advancing panzers. The German 16th Panzer Division reportedly had to fight the 1077th's gunners "shot for shot" until all 37 anti-aircraft guns were destroyed or overrun. The 16th Panzer was shocked to find that, due to Soviet manpower shortages, it had been fighting female soldiers.[63][64] In the early stages of the battle, the NKVD organised poorly armed "Workers' militias" similar to those that had defended the city twenty-four years earlier, composed of civilians not directly involved in war production for immediate use in the battle. The civilians were often sent into battle without rifles.[65] Staff and students from the local technical university formed a "tank destroyer" unit. They assembled tanks from leftover parts at the tractor factory. These tanks, unpainted and lacking gun-sights, were driven directly from the factory floor to the front line. They could only be aimed at point-blank range through the bore of their gun barrels.[66]

By the end of August, Army Group South (B) had finally reached the Volga, north of Stalingrad. Another advance to the river south of the city followed, while the Soviets abandoned their Rossoshka position for the inner defensive ring west of Stalingrad. The wings of the 6th Army and the 4th Panzer Army met near Jablotchni along the Zaritza on 2 Sept.[67] By 1 September, the Soviets could only reinforce and supply their forces in Stalingrad by perilous crossings of the Volga under constant bombardment by artillery and aircraft.

On 5 September, the Soviet 24th and 66th Armies organized a massive attack against XIV Panzer Corps. The Luftwaffe helped repel the offensive by heavily attacking Soviet artillery positions and defensive lines. The Soviets were forced to withdraw at midday after only a few hours. Of the 120 tanks the Soviets had committed, 30 were lost to air attack.[68]

Soviet operations were constantly hampered by the Luftwaffe. On 18 September, the Soviet 1st Guards and 24th Army launched an offensive against VIII Army Corps at Kotluban. VIII. Fliegerkorps dispatched wave after wave of Stuka dive-bombers to prevent a breakthrough. The offensive was repelled. The Stukas claimed 41 of the 106 Soviet tanks knocked out that morning, while escorting Bf 109s destroyed 77 Soviet aircraft.[69] Amid the debris of the wrecked city, the Soviet 62nd and 64th Armies, which included the Soviet 13th Guards Rifle Division, anchored their defence lines with strong-points in houses and factories.

Fighting within the ruined city was fierce and desperate. Lieutenant General Alexander Rodimtsev was in charge of the 13th Guards Rifle Division, and received one of two Heroes of the Soviet Union awarded during the battle for his actions. Stalin's Order No. 227 of 27 July 1942 decreed that all commanders who ordered unauthorised retreats would be subject to a military tribunal.[70] Deserters and perceived malingerers were captured or executed after fighting.[71] During the battle the 62nd Army had the most arrests and executions: 203 in all, of which 49 were executed, while 139 were sent to penal companies and battalions.[72][73][74][75] The Germans pushing forward into Stalingrad suffered heavy casualties.

By 12 September, at the time of their retreat into the city, the Soviet 62nd Army had been reduced to 90 tanks, 700 mortars and just 20,000 personnel.[76] The remaining tanks were used as immobile strong-points within the city. The initial German attack on 14 September attempted to take the city in a rush. The 51st Army Corps' 295th Infantry Division went after the Mamayev Kurgan hill, the 71st attacked the central rail station and toward the central landing stage on the Volga, while 48th Panzer Corps attacked south of the Tsaritsa River. Rodimtsev's 13th Guards Rifle Division had been hurried up to cross the river and join the defenders inside the city.[77] Assigned to counterattack at the Mamayev Kurgan and at Railway Station No. 1, it suffered particularly heavy losses.

Though initially successful, the German attacks stalled in the face of Soviet reinforcements brought in from across the Volga. The Soviet 13th Guards Rifle Division, assigned to counterattack at the Mamayev Kurgan and at Railway Station No. 1, suffered particularly heavy losses. Over 30 percent of its soldiers were killed in the first 24 hours, and just 320 out of the original 10,000 survived the entire battle. Both objectives were retaken, but only temporarily. The railway station changed hands 14 times in six hours. By the following evening, the 13th Guards Rifle Division had ceased to exist.

Combat raged for three days at the giant grain elevator in the south of the city. About fifty Red Army defenders, cut off from resupply, held the position for five days and fought off ten different assaults before running out of ammunition and water. Only forty dead Soviet fighters were found, though the Germans had thought there were many more due to the intensity of resistance. The Soviets burned large amounts of grain during their retreat in order to deny the enemy food. Paulus chose the grain elevator and silos as the symbol of Stalingrad for a patch he was having designed to commemorate the battle after a German victory.

Pavlov's House (1943)

In another part of the city, a Soviet platoon under the command of Sergeant Yakov Pavlov fortified a four-story building that oversaw a square 300 meters from the river bank, later called Pavlov's House. The soldiers surrounded it with minefields, set up machine-gun positions at the windows and breached the walls in the basement for better communications.[76] The soldiers found about ten Soviet civilians hiding in the basement. They were not relieved, and not significantly reinforced, for two months. The building was labelled Festung ("Fortress") on German maps. Sgt. Pavlov was awarded the Hero of the Soviet Union for his actions.

The Germans made slow but steady progress through the city. Positions were taken individually, but the Germans were never able to capture the key crossing points along the river bank. By 27 Sept. the Germans occupied the southern portion of the city, but the Soviets held the centre and northern part. Most importantly, the Soviets controlled the ferries to their supplies on the east bank of the Volga.[78]

Soviet assault troops in the battle

German military doctrine was based on the principle of combined-arms teams and close cooperation between tanks, infantry, engineers, artillery and ground-attack aircraft. Some Soviet commanders adopted the tactic of always keeping their front-line positions as close to the Germans as physically possible; Chuikov called this "hugging" the Germans. This slowed the German advance and reduced the effectiveness of the German advantage in supporting fire.[79][80]

The Red Army gradually adopted a strategy to hold for as long as possible all the ground in the city. Thus, they converted multi-floored apartment blocks, factories, warehouses, street corner residences and office buildings into a series of well-defended strong-points with small 5–10-man units. Manpower in the city was constantly refreshed by bringing additional troops over the Volga. When a position was lost, an immediate attempt was usually made to re-take it with fresh forces.

Soviets defend a position.

Bitter fighting raged for ruins, streets, factories, houses, basements, and staircases. Even the sewers were the sites of firefights. The Germans called this unseen urban warfare Rattenkrieg ("Rat War"),[81] and bitterly joked about capturing the kitchen but still fighting for the living room and the bedroom. Buildings had to be cleared room by room through the bombed-out debris of residential areas, office blocks, basements and apartment high-rises. Some of the taller buildings, blasted into roofless shells by earlier German aerial bombardment, saw floor-by-floor, close-quarters combat, with the Germans and Soviets on alternate levels, firing at each other through holes in the floors. Fighting on and around Mamayev Kurgan, a prominent hill above the city, was particularly merciless; indeed, the position changed hands many times.[82][83]

German soldiers positioning themselves for urban warfare (colourised)

The Germans used aircraft, tanks and heavy artillery to clear the city with varying degrees of success. Toward the end of the battle, the gigantic railroad gun nicknamed Dora was brought into the area. The Soviets built up a large number of artillery batteries on the east bank of the Volga. This artillery was able to bombard the German positions or at least provide counter-battery fire.

Snipers on both sides used the ruins to inflict casualties. The most famous Soviet sniper in Stalingrad was Vasily Zaytsev,[84] with 225 confirmed kills during the battle. Targets were often soldiers bringing up food or water to forward positions. Artillery spotters were an especially prized target for snipers.

A significant historical debate concerns the degree of terror in the Red Army. The British historian Antony Beevor noted the "sinister" message from the Stalingrad Front's Political Department on 8 October 1942 that: "The defeatist mood is almost eliminated and the number of treasonous incidents is getting lower" as an example of the sort of coercion Red Army soldiers experienced under the Special Detachments (later to be renamed SMERSH).[85] On the other hand, Beevor noted the often extraordinary bravery of the Soviet soldiers in a battle that was only comparable to Verdun, and argued that terror alone cannot explain such self-sacrifice.[86] Richard Overy addresses the question of just how important the Red Army's coercive methods were to the Soviet war effort compared with other motivational factors such as hatred for the enemy. He argues that, though it is "easy to argue that from the summer of 1942 the Soviet army fought because it was forced to fight," to concentrate solely on coercion is nonetheless to "distort our view of the Soviet war effort."[87] After conducting hundreds of interviews with Soviet veterans on the subject of terror on the Eastern Front – and specifically about Order No. 227 ("Not a step back!") at Stalingrad – Catherine Merridale notes that, seemingly paradoxically, "their response was frequently relief."[88] Infantryman Lev Lvovich's explanation, for example, is typical for these interviews; as he recalls, "[i]t was a necessary and important step. We all knew where we stood after we had heard it. And we all – it's true – felt better. Yes, we felt better."[88]

Many women fought on the Soviet side or were under fire. As General Chuikov acknowledged, "Remembering the defence of Stalingrad, I can't overlook the very important question … about the role of women in war, in the rear, but also at the front. Equally with men they bore all the burdens of combat life and together with us men, they went all the way to Berlin."[89] At the beginning of the battle there were 75,000 women and girls from the Stalingrad area who had finished military or medical training, and all of whom were to serve in the battle.[90] Women staffed a great many of the anti-aircraft batteries that fought not only the Luftwaffe but German tanks.[91] Soviet nurses not only treated wounded personnel under fire but were involved in the highly dangerous work of bringing wounded soldiers back to the hospitals under enemy fire.[92] Many of the Soviet wireless and telephone operators were women who often suffered heavy casualties when their command posts came under fire.[93] Though women were not usually trained as infantry, many Soviet women fought as machine gunners, mortar operators, and scouts.[94] Women were also snipers at Stalingrad.[95] Three air regiments at Stalingrad were entirely female.[94] At least three women won the title Hero of the Soviet Union while driving tanks at Stalingrad.[96]

For both Stalin and Hitler, Stalingrad became a matter of prestige far beyond its strategic significance.[97] The Soviet command moved units from the Red Army strategic reserve in the Moscow area to the lower Volga and transferred aircraft from the entire country to the Stalingrad region.

The strain on both military commanders was immense: Paulus developed an uncontrollable tic in his eye, which eventually affected the left side of his face, while Chuikov experienced an outbreak of eczema that required him to have his hands completely bandaged. Troops on both sides faced the constant strain of close-range combat.[98]

The Stalingrad Tractor Factory in the northernmost part of the city in 1942

After 27 September, much of the fighting in the city shifted north to the industrial district. Having slowly advanced over 10 days against strong Soviet resistance, the 51st Army Corps was finally in front of the three giant factories of Stalingrad: the Red October Steel Factory, the Barrikady Arms Factory and Stalingrad Tractor Factory. It took a few more days for them to prepare for the most savage offensive of all, which was unleashed on 14 October.[99] Exceptionally intense shelling and bombing paved the way for the first German assault groups. The main attack (led by the 14th Panzer and 305th Infantry Divisions) attacked towards the tractor factory, while another assault led by the 24th Panzer Division hit to the south of the giant plant.[100]

Soviet soldiers in the Red October Factory

The German onslaught crushed the 37th Guards Rifle Division of Major General Viktor Zholudev and in the afternoon the forward assault group reached the tractor factory before arriving at the Volga River, splitting the 62nd Army into two.[101] In response to the German breakthrough to the Volga, the front headquarters committed three battalions from the 300th Rifle Division and the 45th Rifle Division of Colonel Vasily Sokolov, a substantial force of over 2,000 men, to the fighting at the Red October Factory.[102]

Fighting raged inside the Barrikady Factory until the end of October.[103] The Soviet-controlled area shrank down to a few strips of land along the western bank of the Volga, and in November the fighting concentrated around what Soviet newspapers referred to as "Lyudnikov's Island", a small patch of ground behind the Barrikady Factory where the remnants of Colonel Ivan Lyudnikov's 138th Rifle Division resisted all ferocious assaults thrown by the Germans and became a symbol of the stout Soviet defence of Stalingrad.[104]

Junkers Ju 87 Stuka dive bombers above the burning city

From 5 to 12 September, Luftflotte 4 conducted 7,507 sorties (938 per day). From 16 to 25 September, it carried out 9,746 missions (975 per day).[105] Determined to crush Soviet resistance, Luftflotte 4's Stukawaffe flew 900 individual sorties against Soviet positions at the Stalingrad Tractor Factory on 5 October. Several Soviet regiments were wiped out; the entire staff of the Soviet 339th Infantry Regiment was killed the following morning during an air raid.[106]

The Luftwaffe retained air superiority into November, and Soviet daytime aerial resistance was nonexistent. However, the combination of constant air support operations on the German side and the Soviet surrender of the daytime skies began to affect the strategic balance in the air. From 28 June to 20 September, Luftflotte 4's original strength of 1,600 aircraft, of which 1,155 were operational, fell to 950, of which only 550 were operational. The fleet's total strength decreased by 40 percent. Daily sorties decreased from 1,343 per day to 975 per day. Soviet offensives in the central and northern portions of the Eastern Front tied down Luftwaffe reserves and newly built aircraft, reducing Luftflotte 4's percentage of Eastern Front aircraft from 60 percent on 28 June to 38 percent by 20 September. The Kampfwaffe (bomber force) was the hardest hit, having only 232 out of an original force of 480 left.[105] The VVS remained qualitatively inferior, but by the time of the Soviet counter-offensive, the VVS had reached numerical superiority.

In mid-October, after receiving reinforcements from the Caucasus theatre, the Luftwaffe intensified its efforts against the remaining Red Army positions holding the west bank. Luftflotte 4 flew 1,250 sorties on 14 October and its Stukas dropped 550 tonnes of bombs, while German infantry surrounded the three factories.[107] Stukageschwader 1, 2, and 77 had largely silenced Soviet artillery on the eastern bank of the Volga before turning their attention to the shipping that was once again trying to reinforce the narrowing Soviet pockets of resistance. The 62nd Army had been cut in two and, due to intensive air attack on its supply ferries, was receiving much less material support. With the Soviets forced into a 1-kilometre (1,000-yard) strip of land on the western bank of the Volga, over 1,208 Stuka missions were flown in an effort to eliminate them.[108]

The Soviet bomber force, the Aviatsiya Dal'nego Deystviya (Long Range Aviation; ADD), having taken crippling losses over the past 18 months, was restricted to flying at night. The Soviets flew 11,317 night sorties over Stalingrad and the Don-bend sector between 17 July and 19 November. These raids caused little damage and were of nuisance value only.[109][110]^: 265

On 8 November, substantial units from Luftflotte 4 were withdrawn to combat the Allied landings in North Africa. The German air arm found itself spread thinly across Europe, struggling to maintain its strength in the other southern sectors of the Soviet-German front.[Note 4]

As historian Chris Bellamy notes, the Germans paid a high strategic price for the aircraft sent into Stalingrad: the Luftwaffe was forced to divert much of its air strength away from the oil-rich Caucasus, which had been Hitler's original grand-strategic objective.[111]

The Royal Romanian Air Force was also involved in the Axis air operations at Stalingrad. Starting 23 October 1942, Romanian pilots flew a total of 4,000 sorties, during which they destroyed 61 Soviet aircraft. The Romanian Air Force lost 79 aircraft, most of them captured on the ground along with their airfields.[112]

After three months of slow advance, the Germans finally reached the river banks, capturing 90% of the ruined city and splitting the remaining Soviet forces into two narrow pockets. Ice floes on the Volga now prevented boats and tugs from supplying the Soviet defenders. Nevertheless, the fighting continued, especially on the slopes of Mamayev Kurgan and inside the factory area in the northern part of the city.[113] From 21 August to 20 November, the German 6th Army lost 60,548 men, including 12,782 killed, 45,545 wounded and 2,221 missing.[114]

During the siege, the German and allied Italian, Hungarian, and Romanian armies protecting Army Group B's north and south flanks had pressed their headquarters for support. The Hungarian 2nd Army was given the task of defending a 200 km (120 mi) section of the front north of Stalingrad between the Italian Army and Voronezh. This resulted in a very thin line, with some sectors where 1–2 km (0.62–1.24 mi) stretches were being defended by a single platoon (platoons typically have around 20 to 50 men). These forces were also lacking in effective anti-tank weapons. Zhukov states, "Compared with the Germans, the troops of the satellites were not so well armed, less experienced and less efficient, even in defence."[116]

Because of the total focus on the city, the Axis forces had neglected for months to consolidate their positions along the natural defensive line of the Don River. The Soviet forces were allowed to retain bridgeheads on the right bank from which offensive operations could be quickly launched. These bridgeheads in retrospect presented a serious threat to Army Group B.[39]

Similarly, on the southern flank of the Stalingrad sector, the front southwest of Kotelnikovo was held only by the Romanian 4th Army. Beyond that army, a single German division, the 16th Motorised Infantry, covered 400 km. Paulus had requested permission to "withdraw the 6th Army behind the Don," but was rejected. According to Paulus' comments to Adam, "There is still the order whereby no commander of an army group or an army has the right to relinquish a village, even a trench, without Hitler's consent."[117]

The Soviet counter-attack at Stalingrad

  German front, 19 November

  German front, 12 December

  German front, 24 December

  Soviet advance, 19–28 November

In autumn, the Soviet generals Georgy Zhukov and Aleksandr Vasilevsky, responsible for strategic planning in the Stalingrad area, concentrated forces in the steppes to the north and south of the city. The northern flank was defended by Hungarian and Romanian units, often in open positions on the steppes. The natural line of defence, the Don River, had never been properly established by the German side. The armies in the area were also poorly equipped in terms of anti-tank weapons. The plan was to punch through the overstretched and weakly defended German flanks and surround the German forces in the Stalingrad region.

During the preparations for the attack, Marshal Zhukov personally visited the front and noticing the poor organisation, insisted on a one-week delay in the start date of the planned attack.[118] The operation was code-named "Uranus" and launched in conjunction with Operation Mars, which was directed at Army Group Center. The plan was similar to the one Zhukov had used to achieve victory at Khalkhin Gol three years before, where he had sprung a double envelopment and destroyed the 23rd Division of the Japanese army.[119]

On 19 November 1942, the Red Army launched Operation Uranus. The attacking Soviet units under the command of Gen. Nikolay Vatutin consisted of three complete armies, the 1st Guards Army, 5th Tank Army and 21st Army, including a total of 18 infantry divisions, eight tank brigades, two motorised brigades, six cavalry divisions and one anti-tank brigade. The preparations for the attack could be heard by the Romanians, who continued to push for reinforcements, only to be refused again. Thinly spread, deployed in exposed positions, outnumbered and poorly equipped, the Romanian 3rd Army, which held the northern flank of the German 6th Army, was overrun.

Behind the front lines, no preparations had been made to defend key points in the rear such as Kalach. The response by the Wehrmacht was both chaotic and indecisive. Poor weather prevented effective air action against the Soviet offensive. Army Group B was in disarray and faced strong Soviet pressure across all its fronts. Hence it was ineffective in relieving the 6th Army.

On 20 November, a second Soviet offensive (two armies) was launched to the south of Stalingrad against points held by the Romanian 4th Army Corps. The Romanian forces, made up primarily of infantry, were overrun by large numbers of tanks. The Soviet forces raced west and met on 23 November at the town of Kalach, sealing the ring around Stalingrad.[120] The link-up of the Soviet forces, not filmed at the time, was later re-enacted for a propaganda film which was shown worldwide..

Manstein's plan to rescue the Sixth Army – Operation Winter Storm – was developed in full consultation with Führer headquarters. It aimed to break through to the Sixth Army and establish a corridor to keep it supplied and reinforced, so that, according to Hitler's order, it could maintain its "cornerstone" position on the Volga, "with regard to operations in 1943". Manstein, however, who knew that Sixth Army could not survive the winter there, instructed his headquarters to draw up a further plan in the event of Hitler's seeing sense.

This would include the subsequent breakout of Sixth Army, in the event of a successful first phase, and its physical reincorporation in Army Group Don. This second plan was given the name Operation Thunderclap. Winter Storm, as Zhukov had predicted, was originally planned as a two-pronged attack. One thrust would come from the area of Kotelnikovo, well to the south, and around 160 kilometres (100 mi) from the Sixth Army. The other would start from the Chir front west of the Don, which was little more than 60 kilometres (40 mi) from the edge of the Kessel, but the continuing attacks of Romanenko's 5th Tank Army against the German detachments along the river Chir ruled out that start-line.

This left only the LVII Panzer Corps around Kotelnikovo, supported by the rest of Hoth's very mixed Fourth Panzer Army, to relieve Paulus's trapped divisions. The LVII Panzer Corps, commanded by General Friedrich Kirchner, had been weak at first. It consisted of two Romanian cavalry divisions and the 23rd Panzer Division, which mustered no more than thirty serviceable tanks. The 6th Panzer Division, arriving from France, was a vastly more powerful formation, but its members hardly received an encouraging impression. The Austrian divisional commander, General Erhard Raus, was summoned to Manstein's royal carriage in Kharkov station on 24 November, where the field marshal briefed him. "He described the situation in very sombre terms", recorded Raus.

Three days later, when the first trainload of Raus's division steamed into Kotelnikovo station to unload, his troops were greeted by "a hail of shells" from Soviet batteries. "As quick as lightning, the Panzergrenadiers jumped from their wagons. But already the enemy was attacking the station with their battle-cries of 'Urrah!'"

By 18 December, the German Army had pushed to within 48 km (30 mi) of Sixth Army's positions. However, the predictable nature of the relief operation brought significant risk for all German forces in the area. The starving encircled forces at Stalingrad made no attempt to break out or link up with Manstein's advance. Some German officers requested that Paulus defy Hitler's orders to stand fast and instead attempt to break out of the Stalingrad pocket. Paulus refused, concerned about the Red Army attacks on the flank of Army Group Don and Army Group B in their advance on Rostov-on-Don, "an early abandonment" of Stalingrad "would result in the destruction of Army Group A in the Caucasus", and the fact that his 6th Army tanks only had fuel for a 30 km advance towards Hoth's spearhead, a futile effort if they did not receive assurance of resupply by air. Of his questions to Army Group Don, Paulus was told, "Wait, implement Operation 'Thunderclap' only on explicit orders!" – Operation Thunderclap being the code word initiating the breakout.[142]

Soviet gains during Operation Little Saturn

On 16 December, the Soviets launched Operation Little Saturn, which attempted to punch through the Axis army (mainly Italians) on the Don. The Germans set up a "mobile defence" of small units that were to hold towns until supporting armour arrived. From the Soviet bridgehead at Mamon, 15 divisions – supported by at least 100 tanks – attacked the Italian Cosseria and Ravenna Divisions, and although outnumbered 9 to 1, the Italians initially fought well, with the Germans praising the quality of the Italian defenders,[143] but on 19 December, with the Italian lines disintegrating, ARMIR headquarters ordered the battered divisions to withdraw to new lines.[144]

The fighting forced a total revaluation of the German situation. Sensing that this was the last chance for a breakout, Manstein pleaded with Hitler on 18 December, but Hitler refused. Paulus himself also doubted the feasibility of such a breakout. The attempt to break through to Stalingrad was abandoned and Army Group A was ordered to pull back from the Caucasus. The 6th Army now was beyond all hope of German relief. While a motorised breakout might have been possible in the first few weeks, the 6th Army now had insufficient fuel and the German soldiers would have faced great difficulty breaking through the Soviet lines on foot in harsh winter conditions. But in its defensive position on the Volga, the 6th Army continued to tie down a significant number of Soviet Armies.[145]

On 23 December, the attempt to relieve Stalingrad was abandoned and Manstein's forces switched over to the defensive to deal with new Soviet offensives.[146] As Zhukov states, "The military and political leadership of Nazi Germany sought not to relieve them, but to get them to fight on for as long possible so as to tie up the Soviet forces. The aim was to win as much time as possible to withdraw forces from the Caucasus (Army Group A) and to rush troops from other Fronts to form a new front that would be able in some measure to check our counter-offensive."[147]

Commander-in-chief of the Don Front The Stalingrad Master General Konstantin Rokossovsky

759,560 Soviet personnel were awarded this medal for the defence of Stalingrad from 22 December 1942.

The Red Army High Command sent three envoys while simultaneously aircraft and loudspeakers announced terms of capitulation on 7 January 1943. The letter was signed by Colonel-General of Artillery Voronov and the commander-in-chief of the Don Front, Lieutenant-General Rokossovsky. A low-level Soviet envoy party (comprising Major Aleksandr Smyslov, Captain Nikolay Dyatlenko and a trumpeter) carried generous surrender terms to Paulus: if he surrendered within 24 hours, he would receive a guarantee of safety for all prisoners, medical care for the sick and wounded, prisoners being allowed to keep their personal belongings, "normal" food rations, and repatriation to any country they wished after the war. Rokossovsky's letter also stressed that Paulus' men were in an untenable situation. Paulus requested permission to surrender, but Hitler rejected Paulus' request out of hand. Accordingly, Paulus did not respond.[148][149] The German High Command informed Paulus, "Every day that the army holds out longer helps the whole front and draws away the Russian divisions from it."[150]

The Germans inside the pocket retreated from the suburbs of Stalingrad to the city itself. The loss of the two airfields, at Pitomnik on 16 January 1943 and Gumrak on the night of 21/22 January,[151] meant an end to air supplies and to the evacuation of the wounded.[37]^: 98 The third and last serviceable runway was at the Stalingradskaya flight school, which reportedly had the last landings and takeoffs on 23 January.[57] After 23 January, there were no more reported landings, just intermittent air drops of ammunition and food until the end.[152]

The Germans were now not only starving but running out of ammunition. Nevertheless, they continued to resist, in part because they believed the Soviets would execute any who surrendered. In particular, the so-called HiWis, Soviet citizens fighting for the Germans, had no illusions about their fate if captured. The Soviets were initially surprised by the number of Germans they had trapped and had to reinforce their encircling troops. Bloody urban warfare began again in Stalingrad, but this time it was the Germans who were pushed back to the banks of the Volga. The Germans adopted a simple defence of fixing wire nets over all windows to protect themselves from grenades. The Soviets responded by fixing fish hooks to the grenades so they stuck to the nets when thrown. The Germans had no usable tanks in the city, and those that still functioned could, at best, be used as makeshift pillboxes. The Soviets did not bother employing tanks in areas where urban destruction restricted their mobility.

On 22 January, Rokossovsky once again offered Paulus a chance to surrender. Paulus requested that he be granted permission to accept the terms. He told Hitler that he was no longer able to command his men, who were without ammunition or food.[153] Hitler rejected it on a point of honour. He telegraphed the 6th Army later that day, claiming that it had made a historic contribution to the greatest struggle in German history and that it should stand fast "to the last soldier and the last bullet." Hitler told Goebbels that the plight of the 6th Army was a "heroic drama of German history."[154] On 24 January, in his radio report to Hitler, Paulus reported: "18,000 wounded without the slightest aid of bandages and medicines."[155]

On 26 January 1943, the German forces inside Stalingrad were split into two pockets north and south of Mamayev-Kurgan. The northern pocket consisting of the VIIIth Corps, under General Walter Heitz, and the XIth Corps, was now cut off from telephone communication with Paulus in the southern pocket. Now "each part of the cauldron came personally under Hitler."[156] On 28 January, the cauldron was split into three parts. The northern cauldron consisted of the XIth Corps, the central with the VIIIth and LIst Corps, and the southern with the XIVth Panzer Corps and IVth Corps "without units". The sick and wounded reached 40,000 to 50,000.[157]

On 30 January 1943, the 10th anniversary of Hitler's coming to power, Goebbels read out a proclamation that included the sentence: "The heroic struggle of our soldiers on the Volga should be a warning for everybody to do the utmost for the struggle for Germany's freedom and the future of our people, and thus in a wider sense for the maintenance of our entire continent."[158] Paulus notified Hitler that his men would likely collapse before the day was out. In response, Hitler issued a tranche of field promotions to the Sixth Army's officers. Most notably, he promoted Paulus to the rank of Generalfeldmarschall. In deciding to promote Paulus, Hitler noted that there was no record of a German or Prussian field marshal having ever surrendered. The implication was clear: if Paulus surrendered, he would shame himself and would become the highest-ranking German officer ever to be captured. Hitler believed that Paulus would either fight to the last man or commit suicide.[159]

On the next day, the southern pocket in Stalingrad collapsed. Soviet forces reached the entrance to the German headquarters in the ruined GUM department store.[160] When interrogated by the Soviets, Paulus claimed that he had not surrendered. He said that he had been taken by surprise. He denied that he was the commander of the remaining northern pocket in Stalingrad and refused to issue an order in his name for them to surrender.[161][162]

There was no one with a camera present to film the capture of Paulus. One person, though, Roman Karmen, managed to record the first interrogation of Paulus that took place the same day, at Shumilov's 64th Army's HQ, and a few hours later at Rokossovsky's Don Front HQ.[163]

The central pocket, under the command of Heitz, surrendered the same day, while the northern pocket, under the command of General Karl Strecker, held out for two more days.[164] Four Soviet armies were deployed against the northern pocket. At four in the morning on 2 February, Strecker was informed that one of his own officers had gone to the Soviets to negotiate surrender terms. Seeing no point in continuing, he sent a radio message saying that his command had done its duty and fought to the last man. When Strecker finally surrendered, he and his chief of staff, Helmuth Groscurth, drafted the final signal sent from Stalingrad, purposely omitting the customary exclamation to Hitler, replacing it with "Long live Germany!"[165]

Around 91,000 exhausted, ill, wounded, and starving prisoners were taken. The prisoners included 22 generals. Hitler was furious and confided that Paulus "could have freed himself from all sorrow and ascended into eternity and national immortality, but he prefers to go to Moscow."[166]

The losses of transport planes were especially serious, as they destroyed the capacity for supply of the trapped 6th Army. The destruction of 72 aircraft when the airfield at Tatsinskaya Airfield was overrun meant the loss of about 10 percent of the Luftwaffe transport fleet.[176]

These losses amounted to about 50 percent of the aircraft committed and the Luftwaffe training program was stopped and sorties in other theatres of war were significantly reduced to save fuel for use at Stalingrad.

In recognition of the determination of its defenders, Stalingrad was awarded the title Hero City in 1945. A colossal monument called The Motherland Calls was erected in 1967 on Mamayev Kurgan, the hill overlooking the city where bones and rusty metal splinters can still be found.[196] The statue forms part of a war memorial complex which includes the ruins of the Grain Silo and Pavlov's House. On 2 February 2013 Volgograd hosted a military parade and other events to commemorate the 70th anniversary of the final victory.[197][198] Since then, military parades have always commemorated the victory in the city.

Every year still, hundreds of bodies of soldiers who died in the battle are recovered in the area around Stalingrad and reburied in the cemeteries at Mamayev Kurgan or Rossoshka.[199]
