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.[30] The remaining tanks were used as immobile strongpoints within the city. The initial German attack attempted to take the city in a rush. One infantry division went after the Mamayev Kurgan, one attacked the central rail station and one attacked toward the central landing stage on the Volga.

Though initially successful, the German attacks stalled in the face of Soviet reinforcements brought in from across the Volga. The 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.
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.[41]
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 strongpoints with small 5–10 man units.[41] 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.
Soviet soldiers in the Red October Factory
Bitter fighting raged for every ruin, street, factory, house, basement, and staircase. Even the sewers were the sites of firefights. The Germans, calling this unseen urban warfare Rattenkrieg ("Rat War"),[42] 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 neighborhoods, 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.[41]
Fighting on and around Mamayev Kurgan, a prominent hill above the city, was particularly merciless; indeed, the position changed hands many times.[29]:p?[43]
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.[30] 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 labeled 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. The Germans used airpower, 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 to provide counter-battery fire.
Snipers on both sides used the ruins to inflict casualties. The most famous Soviet sniper in Stalingrad was Vasily Zaytsev,[44] 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).[45]:p.154–168 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.[30]:p.154–168 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."[46] 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."[47] 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."[48]

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."[49] 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.[50] Women staffed a great many of the anti-aircraft batteries that fought not only the Luftwaffe but German tanks.[51] 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.[52] Many of the Soviet wireless and telephone operators were women who often suffered heavy casualties when their command posts came under fire.[53] Though women were not usually trained as infantry, many Soviet women fought as machine gunners, mortar operators, and scouts.[54] Women were also snipers at Stalingrad.[55] Three air regiments at Stalingrad were entirely female.[54] At least three women won the title Hero of the Soviet Union while driving tanks at Stalingrad.[56]
For both Stalin and Hitler, Stalingrad became a matter of prestige far beyond its strategic significance.[57] 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 afflicted 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.[58]
Air attacks

Determined to crush Soviet resistance, Luftflotte 4's Stukawaffe flew 900 individual sorties against Soviet positions at the Dzerzhinskiy 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.[3]:p.83
In mid-October, the Luftwaffe intensified its efforts against remaining Red Army positions holding the west bank. Luftflotte 4 flew 2,000 sorties on 14 October and 550 t (610 short tons) of bombs were dropped while German infantry surrounded the three factories. 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.[3]:p.84
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. After flying 20,000 individual sorties, the Luftwaffe 's original strength of 1,600 serviceable aircraft had fallen to 950. The Kampfwaffe (bomber force) had been hardest hit, having only 232 out of a force of 480 left.[6]:p.95 The VVS remained qualitatively inferior, but by the time of the Soviet counter-offensive, the VVS had reached numerical superiority.

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.[3]:p.82[59]: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 5] The Soviets began receiving material assistance from the American government under the Lend-Lease program. During the last quarter of 1942, the U.S. sent the Soviet Union 45,000 t (50,000 short tons) of explosives and 230,000 t (250,000 short tons) of aviation gas.[60]:p.404
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.[61]
