Move 1The board: a target both sides could see

After Stalingrad and the German recapture of Kharkov in March 1943, the Eastern Front is left with a Soviet bulge around Kursk, about 250 km from north to south and 160 km from east to west. To the north, the German Orel salient; to the south, Belgorod and Kharkov. On the map, the move offers itself: one pincer from the north, another from the south, a meeting at Kursk, and the armies inside are trapped.

On 15 April Hitler signs Operations Order No. 6: the attack, Operation Citadel, is to begin on 3 May or soon after, because it is essential to attack before the Soviets prepare extensive defenses or launch an offensive of their own. Walter Model's 9th Army would attack from the north; Hermann Hoth's 4th Panzer Army and Army Detachment Kempf, under Erich von Manstein, from the south.

A week earlier, on 8 April, Georgy Zhukov had already written to Stalin predicting exactly this double pincer. The most obvious move on the board was obvious to both players.

Move 2The defense decided in April

In the same letter of 8 April, Zhukov proposes not attacking first: make the enemy wear himself out against the defenses, destroy his tanks and only then, with fresh reserves, go over to the general offensive. In meetings from 8 to 12 April, Zhukov and the General Staff, with the front commanders, convince Stalin. Konstantin Rokossovsky's Central Front guards the north, Nikolai Vatutin's Voronezh Front the south, and Ivan Konev's Steppe Front stays behind, kept for the counterblow.

Intelligence came in afterward, and confirmed it. The Lucy ring, in Switzerland, transmitted details of Citadel; John Cairncross, at Bletchley Park, passed raw decrypts of German communications to Moscow; the British warned Stalin officially. But the identity of Lucy's source was never established, and the British warning, according to Dan Zamansky, arrived on 30 April — three weeks after the decision to defend. Geography had already said where; the spies helped say when and with what.

What the April decision bought was time to dig. Six main belts, 130 to 150 km deep on the fronts and close to 300 km counting the reserve; more than 300,000 civilians digging trenches; strongpoints with anti-tank guns in crossfire. In the first line in the south, Christopher Lawrence counts 1,666 anti-tank and 1,624 anti-personnel mines per kilometer.

Move 3Two months waiting for the new weapon

Citadel did not go in on 3 May. On 27 April Model brought Hitler the information that the Soviets were heavily fortifying the shoulders of the salient and recommended dropping or redoing the plan. On 4 May, in Munich, Manstein wanted to attack early and Heinz Guderian said the attack was pointless. Hitler postponed: first to June, waiting for the new tanks — the Panther, more Tigers and the Ferdinand tank destroyer —, then again, with the fear of an Allied landing in the Mediterranean weighing in as well. Only on 1 July did he set the date: 5 July.

The last batch of Panthers arrived six days before. Two hundred rebuilt tanks were delivered to Lauchert's regiment between 23 and 29 June; on 5 July there were 184 operational, and two days later about 40, between combat losses, breakdowns and engine fires. In the north, most of the Ferdinands of one of the battalions were immobilized by mines before the end of the first day.

The order of 15 April said it was necessary to attack before the defense was ready. The attack went in two months later, when it was ready, with a weapon that still broke down.

Move 4The attack: two pincers that did not get halfway

In the north, Model's 9th Army advances little and at great cost. The fighting concentrates at Ponyri and on the Olkhovatka heights, and on 10 July the advance is completely stopped, after something between 8 and 20 km, depending on the source. Kursk lies more than a hundred kilometers from the start lines.

In the south, the 4th Panzer Army goes farther. It breaks through the first and second belts, advances about 29 km by 8 July and, on 11 July, the II SS Panzer Corps is about 3 km from Prokhorovka. Even there the southern pincer had not got halfway to the other.

This is defense in depth doing what it was built to do: each belt broken costs tanks and days, and behind it there is another. The attacker spends in the first phase the strength it needed for the next one.

Move 5Prokhorovka, 12 July: the day that became legend

On the morning of 12 July Pavel Rotmistrov's 5th Guards Tank Army counterattacks the II SS Panzer Corps southwest of Prokhorovka. According to Roman Töppel, who studied the German daily situation maps, the approach of the Soviet army was completely hidden from German intelligence, and the corps was taken by surprise. The Germans had 294 tanks and assault guns in the three divisions, 15 of them Tigers; facing them, about 616 Soviet armored vehicles, of which some 500 attacked in two waves.

The result, from the archives of both sides, is the opposite of the legend. Töppel counts, from the German records, 4 tanks of the II SS Panzer Corps lost for good that day, all Panzer IVs, and about 11 with long-term damage; Karl-Heinz Frieser was already writing that there could not have been more than five. On the Soviet side, the archives cited by Töppel give 382 tanks and self-propelled guns hit and 227 lost for good; Valeriy Zamulin, on another basis, arrives at 194 irrecoverable and 146 damaged. The broadest German counts, which add damaged vehicles or several days, fall between 19 and 80 — none of them near the hundreds of the Soviet version.

Tactically, the counterattack did not destroy the German force, but it ended the advance in the south: the II SS Panzer Corps did not get past Prokhorovka. The number the legend invented was the one for destruction; what the day really produced was a tactical draw that was very expensive for one side only.

Move 6Sicily, Kutuzov and the switch-off

On the night of 9 to 10 July the Allies land in Sicily. On 12 July, while Prokhorovka is happening in the south, Operation Kutuzov begins in the north, against the Orel salient — in the rear of Model's 9th Army, which was already at a standstill. On the night of the 12th to the 13th Hitler summons Manstein and Kluge and orders Citadel stopped, citing the need to send forces to Italy. Manstein wants to continue, saying he is close to breaking through into open ground, and gets only one last local action.

The weight of Sicily is debated. It was the reason given at the time, and the postponements of May and June had already cited the fear of a landing in the Mediterranean. But in the north the offensive had been stopped since 10 July and attacked from the rear since the 12th; in the south, it was the Soviet offensives on the Mius and the Donets, from 17 July, that pulled the II SS Panzer Corps away. Sicily explains when Hitler switched the machine off; it does not explain why it was not getting through.

And then the defender becomes the attacker, as Zhukov had written in April. Kutuzov retakes Orel on 5 August and pushes the Germans back to the Hagen Line by 18 August. Operation Rumyantsev, from 3 August, retakes Belgorod on the 5th and Kharkov on 23 August — the last time the city changes hands in the war. Frieser places the turning point of the Eastern Front in these counteroffensives, not in Citadel.

VerdictWhy it ended the way it did

MythsWhat is told and what the record shows

• What is told

  Prokhorovka was the largest tank battle in history, with hundreds of Tigers destroyed.

  What the record shows

  On 12 July 1943 the II SS Panzer Corps had 294 tanks and assault guns, 15 of them Tigers. It lost 4 tanks for good, all Panzer IVs, according to Roman Töppel from the German archives; Frieser said no more than five. The 5th Guards Tank Army lost 227 for good, in the Soviet archives cited by Töppel, or 194, in Zamulin's count. The more than 400 German tanks destroyed come from Rotmistrov's memoirs and from Soviet historiography. And there was a larger tank battle: Brody and Dubno, in June 1941, with up to 3,500 Soviet and 750 German tanks.

• What is told

  The Soviets won because spies handed over the plan.

  What the record shows

  The Lucy ring and John Cairncross passed on real information, and the British warned Stalin on 30 April. But Zhukov predicted the double pincer and proposed the defense on 8 April, and the decision came out of meetings from 8 to 12 April — before the warnings. Lucy's source was never identified. The salient was the target the map showed to both sides.

• What is told

  Hitler stopped Kursk because of the landing in Sicily.

  What the record shows

  It was the reason he gave on 13 July. But the northern attack had already been stopped since 10 July, and Operation Kutuzov had been hitting Model's rear since the 12th. In the south, it was the Soviet offensives on the Mius and the Donets that pulled out the II SS Panzer Corps. Sicily weighed on the timing of the decision; the offensive was no longer getting through.

• What is told

  The Tigers and the Panthers should have decided the battle.

  What the record shows

  The Panthers debuted with 184 operational on 5 July and about 40 two days later, between losses, breakdowns and engine fires. Most of the Ferdinands of one of the northern battalions got stuck in mines on the first day. And waiting for these weapons is what gave the Soviet defense two months to prepare.
