Kursk, Soviet Union July 13, 1943

On this date in 1943 Operation Citadel (Unternehmen Zitadelle), Adolf Hitler’s delayed gambit to retake the impor­tant Soviet rail hub of Kursk, south of Moscow, and straighten the German line on the East­ern Front failed with devas­tating losses on both sides, but espe­cially to German stra­tegic armored reserves. A day earlier a gigan­tic clash of arms approaching mythic status—upwards of 6,000 tanks, 4,000 air­planes, over 38,000 pieces of heavy artil­lery, and two million men (figures vary by source) com­pressed into a plain of roughly three square miles—ended in a draw near the village of Prokhorovka.

That said, the eleven-day Battle of Kursk was evi­dence that German for­tunes were shifting inex­o­ra­bly toward the Soviet Union in that coun­try’s Great Patri­otic War. In the course of three major engage­ments between July 4 and August 23, 1943, the Wehr­macht (German armed forces) suffered over 200,000 casu­al­ties and lost an esti­mated 760 tanks (323 beyond repair or recovery) and assault guns, the majority to Soviet tanks and dug-in anti­tank guns. The Luft­waffe lost more than 680 air­craft, 159 between July 5 and 16 (Battle of Kursk). Soviet losses were many times higher for the same eight-week period: over 863,000 casu­al­ties, nearly 180,000 between July 5 and 16. But the Wehr­macht had grown power­less to stanch or keep pace with the steady influx of Red Army sol­diers (some drafted from retaken terri­tories) and new mate­riel arriving on the East­ern Front, much of the equip­ment provided by Allied Arctic convoys and overland shipments through Iran. As it turned out, Operation Citadel was the last great offensive in Hitler’s war against the Soviet Union.

The long-standing call by Soviet dictator Joseph Stalin for a second Allied front materi­alized three days earlier, on July 10, 1943. The Anglo-Ameri­can landings in Sicily (Opera­tion Husky) engaged more troops than were in­volved in the Nor­mandy landings eleven months later (Opera­tion Over­lord). The Sicily landings were followed by those on the Ital­ian main­land in Septem­ber (Opera­tions Avalanche, Bay­town, and Slap­stick). Taken together, events in the Mediter­ra­nean Theater forced Hitler to rede­ploy forces from the East­ern to the Italian Front. From the con­clu­sion of the Kursk clash of men and armor to the end of the war in Europe less than two years later, Stalin’s armies advanced relent­lessly west­ward across a broad front. In a series of vicious ham­mer blows, the Soviets deci­mated Hitler’s Army Group Center in Bela­rus (Opera­tion Bagra­tion), anni­hilated Army Group South in the Ukraine, and inflicted crushing casual­ties while knocking Axis part­ners Roma­nia and Hun­gary out of the war. (In early 1943, after Stalin­grad, Hitler’s comrade-in-arms, Benito Musso­lini, with­drew his armed forces from the East.) By Febru­ary 1945 both Hitler’s Wehr­macht and his Thou­sand-Year Reich, plus Mus­solini’s Salò Republic, squeezed by the Western Allies into the northern part of Italy, lay at death’s door.

Above: Soviet advances on the Eastern Front, August 1943 to December 1944. The Kursk salient is the white bulge in the tan area of the colored portion of the map. The Soviets looked upon the sali­ent as the spring­board for the recon­quest of terri­tories and popu­la­tion centers (Orel and Bryansk) to the north­west and, to the south­west, the fertile farm­lands of the Ukraine, with its capital of Kiev, the third largest city in the Soviet Union. The Red Army was delighted that the Germans had chosen to target the Kursk sector, where huge con­cen­tra­tions of Soviet troops and armor were amassed, in some places stretching as deep as 65 miles from the front lines. (Soviet supe­riority in the Kursk sector was 3:1 in man­power and 1.5:1 in armor.) On July 13, 1943, Hitler aborted Oper­a­tion Citadel, having failed to put more than a couple of dents in the Kursk bulge. Over the next months the Wehr­macht, attritted of men, machines, and equip­ment, was repeatedly rolled up by Red Army oper­a­tional and stra­tegic reserves after first being mauled, ground down, and dis­located by powerful Soviet formations along a very broad front.

The quality of the optics of the Tiger I and the high velocity 88mm gun it mounted allowed it to devas­tate targets at long range with great accu­racy. Hitler post­poned Oper­a­tion Citadel in part to give German arma­ment manu­fac­turers time to rush new Mark VI Tiger and Mark V Panther tanks, which were con­sidered superior to anything the Soviets possessed, to the Eastern Front.

Left: Three Soviet Ilyushin IL-2 Sturmovik assault aircraft attack enemy ground troops in the south­ern sec­tor (Voro­nezh Front) of the Kursk sali­ent, July 1943. The Soviet offen­sive lasted from July 12 to August 23, 1943. Some 36,183 of these two-seater, single-engine, armor-plated mono­planes were produced during the war, mostly to the east of the Ural Moun­tains away from the Luft­waffe’s long reach. Nick­named “The Flying Tank” by intimi­dated German ground troops, the IL‑2 carried small-caliber bombs in its bomb bay that, when dropped in a carpet of bombs, could also “kill” thick-armored Panther Mark V and Tiger I German tanks. A proto­type of the Ilyushin IL‑2 first flew in October 1940, and Red Army units began receiving deliveries in May 1941. In combi­nation with its faster, more maneu­ver­able succes­sor, the Ilyushin IL‑10 intro­duced in 1944, a total of 42,330 Ilyushin IL‑2s were built, making it the single most produced military aircraft design in aviation history.

The 11‑day German offen­sive at Kursk was the first time a Blitz­krieg (“lightning war”) had been blunted before it could break through enemy defenses and into its stra­tegic depths. Kursk was the Soviets’ critical contribution to winning the war against Hitler and his Third Reich.
