Eastern Front (World War II)
Kursk: Summer 1943

After the failure of the attempt to capture Stalingrad, Hitler had delegated planning authority for the upcoming campaign season to the German Army High Command and reinstated Heinz Guderian to a prominent role, this time as Inspector of Panzer Troops. Debate among the General Staff was polarised, with even Hitler nervous about any attempt to pinch off the Kursk salient. He knew that in the intervening six months the Soviet position at Kursk had been reinforced heavily with anti-tank guns, tank traps, landmines, barbed wire, trenches, pillboxes, artillery and mortars.

However, if one last great blitzkrieg offensive could be mounted, then attention could then be turned to the Allied threat to the Western Front. Certainly, the peace negotiations in April had gone nowhere. The advance would be executed from the Orel salient to the north of Kursk and from Belgorod to the south. Both wings would converge on the area east of Kursk, and by that means restore the lines of Army Group South to the exact points that it held over the winter of 1941–1942.

In the north, the entire German 9th Army had been redeployed from the Rzhev salient into the Orel salient and was to advance from Maloarkhangelsk to Kursk. But its forces could not even get past the first objective at Olkhovatka, just 8 km (5.0 mi) into the advance. The 9th Army blunted its spearhead against the Soviet minefields, frustratingly so considering that the high ground there was the only natural barrier between them and flat tank country all the way to Kursk. The direction of advance was then switched to Ponyri, to the west of Olkhovatka, but the 9th Army could not break through here either and went over to the defensive. The Red Army then launched a counter-offensive, Operation Kutuzov.

On 12 July, the Red Army battled through the demarcation line between the 211th and 293rd divisions on the Zhizdra River and steamed towards Karachev, right behind them and behind Orel. The southern offensive, spearheaded by 4th Panzer Army, led by Gen. Col. Hoth, with three Tank Corps made more headway. Advancing on either side of the upper Donets on a narrow corridor, the II SS Panzer Corps and the Großdeutschland Panzergrenadier divisions battled their way through minefields and over comparatively high ground towards Oboyan. Stiff resistance caused a change of direction from east to west of the front, but the tanks got 25 km (16 mi) before encountering the reserves of the Soviet 5th Guards Tank Army outside Prokhorovka. Battle was joined on 12 July, with about one thousand tanks being engaged.

After the war, the battle near Prochorovka was idealised by Soviet historians as the largest tank battle of all time. The meeting engagement at Prochorovka was a Soviet defensive success, albeit at heavy cost. The Soviet 5th Guards Tank Army, with about 800 light and medium tanks, attacked elements of the II SS Panzer Corps. Tank losses on both sides have been the source of controversy ever since. Although the 5th Guards Tank Army did not attain its objectives, the German advance had been halted.

At the end of the day both sides had fought each other to a standstill, but regardless of the German failure in the north Manstein proposed he continue the attack with the 4th Panzer Army. The Red Army started the strong offensive operation in the northern Orel salient and achieved a breakthrough on the flank of the German 9th Army. Also worried by the Allies' landing in Sicily on 10 July, Hitler made the decision to halt the offensive even as the German 9th Army was rapidly giving ground in the north. The Germans' final strategic offensive in the Soviet Union ended with their defence against a major Soviet counteroffensive that lasted into August.

The Kursk offensive was the last on the scale of 1940 and 1941 that the Wehrmacht was able to launch; subsequent offensives would represent only a shadow of previous German offensive might.
