How the Soviets crushed the Nazis at Kursk, the largest tank battle of WWII

Kursk formed a large salient that jutted into German-held territory, creating an opportunity for the Wehrmacht to strike from both the north and south, and potentially trapping the Soviet armies within it.

If successful, the Germans could have regained the initiative on the Eastern Front and destabilized Soviet defenses.

For the Soviets, holding Kursk was essential not only to protect key railways and cities but also to maintain the momentum gained after their victory at Stalingrad.

The region was heavily fortified in anticipation of the German assault, as its loss could have opened the way for further German advances into Soviet territory. 

Following their defeat at Stalingrad in early 1943, the Germans found themselves in a weakened but determined position.

The loss of an entire army, the Sixth Army, combined with the depletion of resources and manpower, forced them to reconsider their strategy.

Adolf Hitler and his high command believed that another offensive, which was code-named Operation Citadel, could restore German dominance in the east.

The plan was approved in May 1943, which involved an encirclement that aimed to destroy the Soviet forces within the Kursk salient.

Erich von Manstein, who was the commander of Army Group South, supported the plan but favored a more flexible approach.

He wanted to strike sooner, using a mobile defense to lure Soviet forces into a trap. Günther von Kluge, who led Army Group Center, agreed with a more conservative timeline, preferring to build up strength before the attack.

However, Hitler insisted on a delay until Germany’s new Panther and Tiger tanks were ready, which ultimately gave the Soviets more time to prepare. 

By spring 1943, Soviet intelligence had intercepted key details about the upcoming offensive.

General Georgy Zhukov, one of Stalin’s most trusted commanders, understood the significance of the impending attack.

Instead of attempting a preemptive strike, the Soviet leadership chose to prepare a massive defensive line to absorb the German assault.

So, in the months leading up to the battle, Zhukov and Rokossovsky prioritized defense, building three defensive belts packed with artillery, mines, and infantry.

Soviet engineers constructed an intricate network of trenches, anti-tank barriers, and minefields, which were designed to blunt the German advance.

They were prepared to lose ground initially but aimed to exhaust the Germans before striking back.

Zhukov’s colleague, Konstantin Rokossovsky, who commanded the Central Front, was responsible for the northern sector of the Kursk salient.

Both commanders worked closely with Nikolai Vatutin, who was in charge of the Voronezh Front in the south, to ensure that every sector of the salient was fortified with minefields, anti-tank guns, and reserves. 

The German offensive on July 5, 1943, began with a ferocious artillery barrage and air strikes aimed at softening the Soviet defenses along the northern and southern flanks of the Kursk salient.

In the north, General Model’s Ninth Army advanced toward the Soviet Central Front under Rokossovsky.

However, they encountered heavily fortified positions that slowed the German tanks to a crawl.

In particular, Soviet minefields and defensive layers inflicted heavy losses, with the Germans advancing only a few miles after days of intense fighting.

In the south, General Hoth’s Fourth Panzer Army faced the Voronezh Front under Vatutin.

Here, the German tanks initially made more progress, thanks to more favorable terrain and fewer defenses.

However, the Soviets had prepared for this offensive for months, and the depth of their defenses, combined with Soviet air support, significantly blunted the German thrust.

By July 11, the Germans had failed to achieve a breakthrough in either sector. 

The Soviet counteroffensive began on July 12 with a powerful strike against the German forces.

One of the most pivotal moments occurred that day at the Battle of Prokhorovka, where over 1,000 tanks clashed in what became one of the largest armored battles in history.

The Soviet Fifth Guards Tank Army, led by General Rotmistrov, charged into German lines to halt the advancing II SS Panzer Corps.

Although the Soviets suffered heavy losses, they succeeded in halting the German advance, preventing them from reaching Kursk.

The sheer scale of the losses at Prokhorovka, particularly for the Germans, played a critical role in the overall failure of Operation Citadel.

The Germans lost nearly 300 tanks and a significant number of experienced crew members.

The loss of so many tanks, combined with dwindling manpower, severely reduced the combat effectiveness of their forces.

German commanders, including General Hoth, understood that they could no longer sustain prolonged offensive operations.

This led to a growing sense of despair within the Wehrmacht, as their ability to regain the initiative slipped away.

As a result, the German high command decided to call off Operation Citadel and convinced Hitler to shift resources to Italy, where the Allies had invaded Sicily. 

Following this, the Soviets launched a massive series of counterattacks that exploited the weakened German forces.

By July 23, the Soviets had fully regained control of the northern and southern flanks of the Kursk salient.

Soviet forces, now reinforced by fresh reserves, pushed the Germans back along a broad front.

The relentless Soviet advance continued through August, with key engagements occurring around the cities of Orel and Kharkov.

The Germans, depleted and unable to regroup effectively, lost control of these crucial areas.

Consequently, this led to the collapse of German defenses in the region, opening the path for Soviet forces to continue their advance toward the Dnieper River and, eventually, into German-held territories in Eastern Europe.

As such, the Battle of Kursk had ended in a decisive Soviet victory, permanently crippling German offensive capabilities on the Eastern Front. 

The Battle of Kursk saw some of the most advanced and powerful tanks of World War II face off in massive numbers.

The Germans deployed their formidable Tiger and Panther tanks, which were equipped with thick armor and high velocity 88mm and 75mm guns.

The Tiger tank, which weighed 57 tons, had a reputation for destroying Soviet tanks from great distances.

However, these heavy tanks were often outnumbered and mechanically harder to repair. In total, the Germans fielded around 3,000 tanks, while the Soviets countered with over 5,000, including the reliable T-34.

The T-34, with its sloped armor and a 76mm gun, proved to be a more mobile and resilient machine, able to withstand rough terrain and the brutal conditions of the battlefield.

Its simplicity and ease of production allowed the Soviets to field large numbers, compensating for the technical superiority of German tanks. 

Also, the Luftwaffe launched hundreds of sorties, employing planes like the Junkers Ju 87 Stuka, known for its accuracy in dive-bombing, and the Focke-Wulf Fw 190, which provided air cover for the advancing German forces.

Despite the Luftwaffe’s experience, the Soviets met them with sheer numbers, deploying over 2,500 aircraft, including the Yakovlev Yak-9 and the Ilyushin Il-2 Shturmovik.

The Il-2, nicknamed the 'flying tank', was heavily armored and specialized in ground-attack missions, which devastated German armor and infantry with rockets and cannons.

Although the Luftwaffe initially achieved some local air superiority, the Soviet air forces gradually overwhelmed them through attrition and superior numbers. 

On the ground, had laid nearly one million anti-tank and anti-personnel mines.

This created dense minefields that disrupted German advances and slowed their armored divisions.

In addition, the Soviets deploying over 20,000 guns and mortars to bombard German positions.

Anti-tank weapons, such as the ZIS-3 76mm field gun, proved effective against even the most heavily armored German vehicles.

The Germans, on the other hand, used self-propelled guns like the Sturmgeschütz III to provide mobile fire support.

As the battle progressed, the combination of Soviet artillery, minefields, and anti-tank defenses turned the battlefield into a brutal, grinding arena, where the German tanks struggled to maintain their momentum under continuous fire. 

The Battle of Kursk resulted in staggering losses for both sides. German casualties are estimated to have reached nearly 200,000 men, along with the destruction of around 1,500 tanks, 3,000 aircraft, and thousands of other vehicles.

On the Soviet side, the Red Army lost over 250,000 soldiers, but their losses in tanks and aircraft were far more easily replenished, thanks to their superior production capabilities.

Soviet forces lost over 1,600 tanks and 1,000 aircraft, but their reserves allowed them to continue the fight without the crippling shortages that plagued the Germans.

The sheer scale of the battle left the German forces exhausted, with little ability to replace their lost materiel and manpower. 

Ultimately, the Germans underestimated the Soviet ability to gather intelligence, allowing the Red Army to prepare for the attack well in advance.

The decision to rely heavily on newly developed tanks like the Tiger and Panther. As a result, the German forces became bogged down in a war of attrition, which they were ill-prepared to sustain.

Following the failure of Operation Citadel, the Red Army moved from a defensive posture to an unrelenting offensive that would continue until the fall of Berlin in 1945.

Ultimately, the battle demonstrated the growing strength of the Soviet Union, both in terms of military strategy and industrial capacity.

For the Germans, Kursk shattered their last hopes of regaining the initiative in the East, and from this point forward, they were forced to fight a defensive war, retreating further with each passing month.
