You mean where the German counterstrokes completely failed to stop the Soviets advance despite some tactical success?
5th tank army was smashed again and the only reason the Soviets won was the start of Sicily necessitating transfers,
Sicily transfers had already occurred and the smashing of 5th Tank Army did not actually stop the overall Soviet advance. There also isn't really any reason to believe that the overall outcome would have been much different even without the Sicilian transfers.
the Germans using up their artillery stocks at Kursk (Zetterling had them using 3:1 ammo vs the Soviets, which accounts for a large part of the reason for Soviet defensive losses) so running out during the battle for the city,
Shortages which manifested well after the fate of the city had already been decided and German defenses were already crumbling.
and the general lack of replacements that bit them in the ass after Kursk/Orel/Mius/Smolensk/Sicily-Italy was going down.
The Germans always suffered from a general lack of replacements, that was nothing new. Plus, Orel/Mius/Sicily/Smolensk are still going down even if Citadel isn't and those were what overstretched Germany to the breaking point, not Citadel.
Drop Kursk and there are ammo and manpower reserves, plus fully rebuilt Panzer divisions ready for a Soviet offensive (IIRC by pre-Zitadel July 1943 they were at the closest to TOE numbers since 1941).
Ignores that the Soviets are also starting ahead of time also with far more reserves as well and tended to inflict even worse losses upon the Germans in the attack then they did in the defense even in mid-'43. The Germans burned through three times the number of men and machines fighting the Soviet offensives then they did attacking the Soviet defenses.
