KURSK - the greatest tank battle of World War 2
The last major German offensive in the East 

In the winter and spring of 1943, after their terrible defeat in Stalingrad, clearly outnumbered and losing the initiative in the eastern front, Hitler and the German High Command were asking themselves what to do next, in the summer of 1943.

The situation was bad not only on the war front.

While Russian tank production increased to unbelievable levels, the German obsession for complex new super weapons, like the advanced but then immature Panther and Tiger tanks, largely reduced German tank production.

General Guderian, the best German armor expert and commander, said:

As interesting as these designs were, the practical result was just a reduced production of the Panzer 4, our only efficient tank then, to a very modest level...

Shortly before the battle of Kursk Guderian added, about the Panther and its crews:

They are simply not ready yet for the front.

In early 1943 the Germans were about to destroy their own tank production rates by terminating Panzer 4 production in return for a production of just 25 new Tigers per month, but at a moment of reason Hitler gave control of tank production to Guderian who stopped this idea.

The German Plan

The debate in the German High Command about what to do in the summer of 1943 was between two options, the realistic option and the enthusiast-optimist option:

The realistic option, supported by Guderian and Manstein, the best German field commanders, and by others, suggested to compensate for the large Russian numerical advantage by fully utilizing the superiority of the German commanders and soldiers in tactics, command, and fighting, by a strategy of dynamic mobile defense that would cause great losses to the Russians in a series of local clashes. The realistic goal was to stop and delay the Russians, as decisive victory was no longer achievable.

The enthusiast-optimistic option, proposed by General Zeitzler, chief of staff of the German army, suggested to concentrate almost all German tanks, and other forces, to a major decisive battle against a large portion of the Russian armor, in order to destroy them and by doing so hopefully regain the initiative. The most suitable place for such a battle, as Zeitzler proposed, was the Kursk salient, a wide region around the city of Kursk, about half way between Moscow and the black sea, where the Germans surrounded the Russians from three sides. It was obvious that the Russians will keep a large tank force there, and the plan was to encircle them in a classic Blitzkrieg style pincer movement of German tanks from North and South and destroy them. Zeitzler's plan was code named Operation Citadel.

When Hitler discussed the two options with his Generals on May 4th, exactly two months before the German attack began, it became clear that each of the two options had a major problem.

The major problem with Zeitzler's plan to attack the Kursk salient, was that aerial photos clearly revealed that the Russians were building dense and deep fortifications there in order to counter such an attack, and that many Russian tanks were moved deeper behind the front line. Instead of an open battlefield Blitzkrieg, it was going to be a direct charge on dense anti-tank defences. General von Mellenthin warned that such a direct attack will be a "Totenritt", a ride to death, for the German tanks. In response to Guderian's worries, Hitler himself admitted that whenever he think of this planned attack, his guts turn.

The major problem with Guderian's option was that it lacked the charm, enthusiasm, and optimistic hope for a major change in the war that Zeitzler's plan had. So the enthusiast Hitler decided in favor of Zeitzler's plan, and calmed his worries of it by ordering to delay the attack for a while in order to incorporate more of the brand new advanced German tanks and tank destroyers in it. The date was set to July 4, 1943.

Once the order was given, the Germans prepared as best as they could. The entire region was photographed from above, the German commanders visited the front line to observe their intended routes, and the Germans concentrated all available forces in two armies, North and South of the Kursk salient, leaving minimal forces along the rest of the long Russian front.

The German force included a total of 50 divisions, including 17 armor and mechanized divisions. These included the most powerful and best equipped German divisions, such as the Gross Deutschland (Great Germany) division and the Waffen-SS tank divisions Leibstandarte (Hitler's bodyguards), Totenkopf (Death skull), and Das Reich (The Reich). The Germans concentrated all their new armor, the Tiger and Panther tanks, and the mighty new Elefant tank destroyers, which had a front armor thicker than a battleship's armor. They also concentrated all available air units and artillery, and despite the problems of the German plan it was a formidable concentrated mobile armor force with great offensive potential.

The Russian Preparations

Thanks to their "Lucy" spy network, which operated high ranking sources in Germany via Switzerland, the Russians didn't just expect the German attack, they knew all about it. They received the full details of the German plan, and the Russian military intelligence was able to verify most details in the front to ensure that the information was real, not disinformation.

The Russians prepared eight defence lines one behind the other, and also positioned their entire strategic mobile reserve East of the Kursk salient, in case the Germans will penetrate thru all these defence lines, which indeed happened.

The Russian plan was simple. First, they will let the Germans attack as planned right into their series of very dense defence lines, and after the German armor will be crushed there, the Russian army will start its strategic attack North and South of the Kursk salient and push the Germans West along a wide part of the front.

The Russian defence was unprecedented in its density. A total of 1,300,000 Russian soldiers with 3600 tanks, 20,000 guns, including 6000 76mm anti-tank guns, and 2400 aircraft were concentrated in and around the Kursk salient. It was about a fifth of the Russian military personnel, over a third of the tanks and over 1/4 of the aircraft. They laid 3400 mines per each kilometer of the front, half of them anti-tank mines, and over 300,000 civilians dug thousands of kilometers of anti-tank trenches and other fortifications. The Russian lines were filled with numerous anti-tank guns organized in groups of up to 10, each group commanded by one officer and firing at the same target. The Russian camouflage was superb, the Germans said that until they were hit by them, they could identify neither the Russian mine fields nor their anti-tank gun positions. To avoid forcing the Germans to divert from their known plan, Russian air attacks were delayed until the German tanks already moved into the trap. The Russians were as ready as they could be.

The Battle of Kursk

The German attack finally began, in the afternoon of July 4, 1943, as planned. The German armor spearheads, led by the most armored and most powerful Tigers and Elefants, advanced forward in the wheat fields toward the Russian lines. Then came wave after wave of anti-tank aircraft attacks by both sides, German Stukas attacked dug in Russian tanks and Russian Sturmoviks attacked the German tanks. The fighters of both sides engages in air combats over the battlefield, and each side's massive heavy artillery also fired. The advancing German tanks suffered rapidly increasing losses from the dense Russian anti-tank defences, but pressed forward. Once the German heavy tanks reached into the Russian defense lines, they could finally be hit and destroyed from their sides, where they were not so armored as from the front. At this short range they also lost their superiority in long range firing from their powerful guns.

In the North, the German attack advanced only 10km into the Russian lines in two days and was stopped, after losing about 25,000 soldiers and 200 tanks, but fighting continued. In the South, where they had stronger forces, the Germans sent all their reserves forward and pressed on despite the losses. On July 12, after a week of heavy fighting with heavy casualties in both sides, General Hoth, the German commander in the South side of the Kursk salient, decided to concentrate all his remaining tanks, about 600, and press forward with all their concentrated force deeper, past the last remaining Russian defense line, and into an area more suitable for tank warfare near the small village Prokhorovka.

He didn't know that at this point in the battle, the Russian High Command already predicted this development, and since the German advance in the North was stopped, they could now safely send their armor reserve to meet the advancing German tanks in the South. The Russians ordered their entire 5th Guards tank army, which so far didn't participate in the battle, to hurry at maximum speed from its position East of Kursk to meet the German tanks advancing near Prokhorovka.

Due to very bad visibility, with thick smoke and dust, when the Russian tanks met the German tanks the next morning, they didn't stop advancing until they were all around and between them, so about 1500 German and Russian tanks fought in a fierce battle of very short firing distances in which the Germans could not exploit their technological superiority in longer range fighting. The Germans lost more than half of their remaining tanks in this great clash which lasted eight hours, and the Russians lost greater numbers. The battle was decided. The next day Hitler ordered to stop Operation Citadel, and the Russians started their counter attack north of Kursk.

After the Battle

The battlefield in Kursk was filled with many hundreds of burnt tanks and crashed aircraft, and so many dead soldiers. The difference was that while the Russians suffered heavy losses but could continue as planned and shift from defence to a large counter attack in a wide front, the German army in the East just lost the core of its remaining force.

In the summer of 1941 the German army attacked Russia and was stopped only near Moscow.

In the summer of 1942 the German army attacked in South Russia and reached the Volga river at Stalingrad before it was stopped, and lost the strategic initiative to the recovering Russian army.

In the summer of 1943, in the battle of Kursk, the much weaker German army broke its fist and lost its best remaining units in its attempt to regain the initiative in one last major attack, for which the Russians were fully prepared.

After the battle of Kursk, the war in the eastern front was a long Russian advance, in which the Russian army returned to all the territory it lost to the Germans, conquered all of Eastern Europe, and reached all the way to Germany and to Berlin and won the war. The Germans could no longer attack or stop the Russian advance, and were just pushed back in a long retreat. 


This report, declassified by the National Security Agency only in 1978 is entitled simply "Reports on the Atom-Splitting Bomb"


The contents in their entirety, with the original breaks where they occurred in the text for transmission:



This bomb is revolutionary in its results, and it will completely upset all ordinary precepts of warfare hitherto established. I am sending you, in one group, all those reports on what is called the atom-splitting bomb:


It is a fact that in June of 1943 the German Army tried out an utterly new type of weapon against the Russians at a location 150 kilometers southeast of Kursk. Although it was the entire 19th Infantry Regiment of the Russians which was thus attacked, only a few bombs (each round up to 5 kilograms) sufficed to utterly wipe them out to the last man.


The following is according to a statement by Lieutenant-Colonel UE (?) I KENJI, advisor to the attaché in Hungary and formerly (on duty?) in this country, who by chance saw the actual scene immediately after the above took place:


"All the men and the horses (within the area of?) the explosion of the shells were charred black and even their ammunition had all been detonated "


Moreover, it is a fact that the same type of war material was tried out in the Crimea, too. At that time the Russians claimed that this was poison-gas, and protested that if Germany were ever again to use it, Russia, too, would use poison-gas.


There is also the fact that recently in London - in the period between October and the 15th of November - the loss of life and the damage to business buildings through fires of unknown origin was great. It is clear, judging especially by the articles about a new weapon of this type, which have appeared from time to time recently in British and American magazines - that even our enemy has already begun to study this type.


To generalize on the basis of all these reports: I am convinced that the most important technical advance in the present great war is in the realization of the atom-splitting bomb. Therefore, the central authorities are planning, through research on this type of weapon, to speed up the matter of rendering the weapon practical. And for my part, I am convinced of the necessity for taking urgent steps to effect this end.


The following are the facts I have learned regarding its technical data:


Recently the British authorities warned their people of the possibility that they might undergo attacks by German atom-splitting bombs. The American military authorities have likewise warned that the American east coast might be the area chosen for a blind attack by some sort of flying bomb. It was called the German V-3. To be specific, this device is based on the principle of the explosion of the nuclei of the atoms in heavy hydrogen derived from heavy water. (Germany has a large plant (for this?) in the vicinity of Rjukan, Norway, which has from time to time been bombed by English planes.).


Naturally, there have been plenty of examples even before this of successful attempts at smashing individual atoms. However, as far as the demonstration of any practical results is concerned, they seem not to have been able to split large numbers of atoms in a single group. That is, they require for the splitting of each single atom a force that will disintegrate the electron orbit.


On the other hand, the stuff that the Germans are using has, apparently, a very much greater specific gravity than anything heretofore used. In this connection, allusions have been made to SIRIUS and stars of the "White Dwarf" group. (Their specific gravity is (6?) 1 thousand, and the weight of one cubic inch is 1 ton.)


In general, atoms cannot be compressed into the nuclear density. However, the terrific pressures and extremes of temperature in the "White Dwarfs" cause the bursting of the atoms and A-GENSHI HAKAI DAN. That is, a bomb deriving its force from the release of atomic energy.


There are, moreover, radiations from the exterior of these stars composed of what is left of the atoms which are only the nuclei, very small in volume.


According to the English newspaper accounts, the German atom-splitting device is the NEUMAN disintegrator. Enormous energy is directed into the central part of the atom and this generates at atomic pressure of several tons of thousands of tons (sic) per square inch. This device can split the relatively unstable atoms of such elements as uranium. Moreover, it brings into being a store of explosive atomic energy. 


The end of this amazing intercept then reads:

Inter 12 Dec 44 (1,2) Japanese; Rec'd 12 Dec 44; Trans  14 Dec 44 (3020-B), apparently references to when the message was intercepted by American intelligence, its original language (Japanese), when the message was received, when it was translated, and by whom (3020- B).


-- Edgar Mayer and Thomas Mehner, "Hitler und die Bombe" (Rottenburg: Kopp Verlag, 2002), citing "Stockholm to Tokyo, No. 232.9 December 1944 (War Department), National Archives, RG 457, SRA 14628-32, declassified 1 October 1978.


The date of this document two days before the beginning of the Battle of the Bulge must have set off alarm bells in the offices of Allied Intelligence personnel both during and after the war. While it is certainly clear that the Japanese attaché in Stockholm seems to be somewhat confused about the nature of nuclear fission, a number of startling things stand out in the document:


(1) The Germans were, according to the report, using weapons of mass destruction of some type on the Eastern Front, but had apparently for some reason refrained from using them on the Western Allies;


(a) The areas specifically mentioned were Kursk, in the approximate location of the southern pincer of the German offensive, which took place in July, and not June, of 1943, and the Crimean peninsula;


(b) The time mentioned was 1943, though since the only major action to have occurred in the Crimea was in 1942 with the massive German artillery bombardment, one must also conclude that the time frame stretched back into 1942;

At this juncture is it worth pausing to consider briefly the German siege of the Russian fortress of Sevastopol, scene of the most colossal artillery bombardment of the war, as it bears directly on the interpretation of this intercept.


The siege was led by Colonel-General (later Field Marshal) Erich von Manstein's 11th Army. Von Manstein assembled 1,300 artillery pieces - the largest concentration of heavy and super-heavy artillery deployed by any Power during the war - and pounded Sevastopol with this mighty arsenal twenty-four hours a day for five clays. These were no ordinary heavy field pieces.


Two mortar regiments - the 1st Heavy Mortar Regiment and the 70th Mortar Regiment - as well as the 1st and 4th Mortar Battalions, had been concentrated in front of the fortress under the special command of Colonel Nieman - altogether 21 batteries with 576 barrels, including the batteries of the 1st Heavy Mortar regiment with the 11- and 12 1/2 inch high explosive and incendiary oil shells...


Even these monsters were not the largest pieces deployed at Sevastopol. Several of the 16 1/2 inch "Big Bertha" Krupp cannon and their old Austrian Skoda counterparts were massed against the Russian positions, along with the even more colossal "Karl" and "Thor" mortars, gigantic self-propelled 24 inch mortars firing shells that weighed over two tons.


But even "Karl" was not quite the last word in gunnery. That last word was stationed at Bakhchisary, in the "Palace of Gardens" of the ancient residence of the Tartar Khans, and was called "Dora," or occasionally "Heavy Gustav." It was the heaviest gun of the last war. Its caliber was 31 1/2 inches. Sixty railway carriages were needed to transport the parts of the monster. Its 107-foot barrel ejected high-explosive projectiles of 4800 kg -i.e., nearly five tons- over a distance of 29 miles. Or it could hurl even heavier armour-piercing missiles, weighing seven tons, at targets nearly 24 miles away. The missile together with its cartridge measured nearly twenty-six feet in length. Erect that would be about (the) height of a two-storey house....


These data are sufficient to show that here the conventional gun had been enlarged to gigantic, almost super-dimensional scale - indeed, to a point where one might question the economic return obtained from such a weapon. Yet one single round from "Dora" destroyed an ammunition dump in Severnaya Bay at Sevastopol although it was situated 100 feet below ground.


"So horrendous was the bombardment from this massed heavy and super-heavy artillery that the German General Staff estimated that over 500 rounds fell on Russian positions per second during the five days' artillery and aerial bombardment, a massive expenditure of ammunition. The rain of steel on the Russian positions pulverized Russian morale and was often so thunderous that eardrums burst. At the end of the battle, the city and environs of Sevastopol were ruined, two entire Soviet armies had been obliterated, and over 90,000 prisoners were taken".

~Paul Carrell, "Hitler Moves East", 1941-1943 (Ballantine Books, 1971)

Why are these details significant? First, note the reference to "incendiary oil shells." These shells are the indication that unusual weaponry was deployed by the Germans at Sevastopol and delivered through conventional - though quite large - artillery pieces. The German Army did possess such shells and deployed the frequently and with no little effectiveness on the Eastern Front.


But might there have been an even more fearsome weapon? The Germans indeed developed an early version of a modern "fuel-air" bomb, a conventional explosive with the explosive power of a tactical nuclear weapon. Given the great weight of such projectiles, and the German lack of sufficient heavy-lift aircraft to deliver them, it is possible if not likely that super-heavy artillery was used to deploy them. This would also explain another curiosity in the Japanese military attaché's statement: the Germans apparently did not deploy weapons of mass destruction against cities, but only against military targets that would have been within the range of such weapons.

To resume the analysis of the Japanese statement:


(2) The Germans may have been seriously pursuing the hydrogen bomb, since reactions of the nuclei of heavy water atoms -containing deuterium and tritium- are essential in thermonuclear fusion reactions, a point highlighted by the Japanese delegate (though he confuses these reactions with fission reactions of atom bombs)

(3) The enormous temperatures of atom bombs are used as detonators in conventional hydrogen bombs;


(4) In desperation the Russians appeal to have been ready to resort to the use of poison gas against the Germans if they did not "cease and desist";


(5) The Russians believe the weapons to have been "poison gas" of some sort, either a cover story put out by the Russians, or a result of field reports being made by Russian soldiers who were ignorant of the type of weapon deployed against them [The detail of "charred bodies" and exploded ammunition certainly point to non-conventional weaponry. A fuel-air device would at least account for the charring. The tremendous heat produced by such a bomb could also conceivably detonate ammunition. Likewise, radioactive burns with its characteristic blistering effects might well have been misunderstood by Russian field soldiers and officers, who would most likely not have been familiar with nuclear energy, as the effects of poison gas]

and finally, and most sensationally,


(6) According to the Japanese cable, the Germans appeared to have gained their specialized knowledge via some connection to the star system of Sirius and that knowledge involved some exotic form of very dense matter, a statement that strains credulity even today.


It is this last point that directs our attention to the most fantastic and arcane recesses of wartime German secret weapons research, for if the allegation has even a partial basis in truth, then it indicates that at some highly secret level, physics, and the esoteric, were being pursued by the Nazi regime in some very extraordinary ways. [To anyone familiar with the wealth of material on alternative research into the Giza compound in Egypt, the reference to Sirius will immediately conjure images of Egyptian religion, its preoccupation with death, with the Osiris myth, and to the Sirian star system].

In this regard it is important to note that the extreme density of the material described by the Japanese envoy resembles nothing so much as a construct of modern post-war theoretical physics called "dark matter". In all likelihood his report greatly overestimates the mass of this material - if it existed at all - but nonetheless it is crucial to observe that it is material far beyond the ordinary density of matter.
