EAST FRONT SCENARIOS NEEDED/MISSING

[Patton]

There are lots of great East Front scenarios, covering most phases of the campaign: Barbarossa, Typhoon, Blau, Stalingrad, Manstein's Kharkov riposte, Kursk, Korsun Pocket, Bagration, and the endgame to Berlin.

But, I can't find any for two parts of the campaign:

1. The Russian counter-attack in December 1941. I know it's included as parts of many other scenarios, but are there any scenarios that start with that attack, taking the historical position as the German attack petered out as the starting point?

2. From Kursk to Korsun: I have never come across any scenario that covers the period of Manstein's vain efforts to stem the Russian tide after Kursk up to the time he was sacked/the Korsun pocket debacle.

Does anyone know of any scenarios that fit either description above?

Thanks for your help!
