The defense of the Tula-Voronezh-Rostov line in the winter of 1942/43:
Part I
First of all - it will be hard, in every way you play (OK, if you play on lower diff and you have plenty of prestige and you have upgraded everything to über units, than not

)!
For success, you will have some earlier tasks successfully fulfilled:
- You do not wasted your units especially the minor allied ones. I think, I don not need to detail this more - in the terror of the Soviet attack, you need all of your units. For defense and for sacrifice...
- You captured at least partly Stalingrad and destroyed several units around and south of it. That is useful later, when you have time and resources to capture itt all and advance further fast. But it is also important, because it gives you time, when the attackers are first tasked to take the captured parts of the city back. If you were able to capture the whole city and you have 1-2 Romanian inf's in the near, than it is useful to send them in the city. They will be destroyed, but their sacrifices buy a lof ot time for you.
- You captured at least several towns, south of Rostov. Again, regardless, if you want to capture the Caucasus later, or not, while the enemy tries to capture these back, he looses precious time.
- Clearing the region north and south of Voronezh, all along the western shore of the Don river. If not, you will have not the space to build up the defense line.
- Capturing Rostov and Voronezh very fast. Because the earlier you capture the city and the region, the more time your units will have to dig in.
The main goal is to avoid high casualties and to block the attackers as long, as the snow is gone and the rivers are again major barriers - and you can use your superior air power too (althrough, in the first clear days, the Soviet airforce will be overhelming, so cautiousness is advised in that time).
Part II
Prelude: Do not forget, that the attack north and south of Stalingrad is already starting in turn 35, when the snow just started raining, but the field, the roads are still in good shape. My tactic is, that I attack the city and the surroundings south of it till the end of turn 34. But I already move the units, which has poor move capability in snow, west, to the safety. Only the tracked units remain. I also move the weakened and disposable units to the area (it depends, what your goals are, how many prestige you get, what is left, etc - Pz35(t), captured French H39, or S-35 Somua and I also perish the Finn 37mm AT gun, because I did not use it later). In turn 35 I move all units as fast as possible to west, south-west, behind the safety of the dug-in inf and AT guns. As rear guards are the disposable units and the captured T-34, eventually some Romanian inf, if needed, because, that loss is less, than taking heavy casualties with your armor.
Army streght: this article shows, how with a medium size and value army group you can still hold out. As I aimed in the last times for the "DV at turn 50" goal, I did not have the "luxury" to fight all of my units the attackers: I just had in this region:
- 1 x Pz IVF2 (upgraded as soon as possible to late G9, 1 x captured T-34, 1 x PzIIIL and a few light armor (Pz IIF, Pz38(t)E and Hungarian G type, the Finnish T-26, Italian L6/40)...and later the Tiger I and the Stug IIIG!
- But I had 5 x German 75mm AT's, the 3x Romanian and Hungarian 47mm AT's (it is not much worth to upgrade them on the low-75mm version - maybe, if you want to use them later, for better upgrade). I did not upgrade any of the AT guns to Stug's, because I did not have the prestige for it and I did not needed it. Sure, the AT guns are more fragile, especially when attacked by arty first, but with smart defense and arty backup, they can mostly survive.
- 7x medium and heavy arty
- a lot of AA! (As I already fought in England, I did not need them in Western Europe - they came really handy, when the swarms of Soviet fighters filled the sky)
- mostly dug-in inf, plus a few other one for backup and some cavalry
* The "gift" Tiger I and the STuG IIIG are your most valuable assets. Take care of them! Guard the railways against partisans and try to give always fighter protection for the Tiger, but at least strong AA defense. Put them int action there, where the frontline got the most weakened or the enemy starts to break through. After the late G variant update, the Pz IVG can also used as firefighter, but it is still vulnerable, so use it carefully. Also the T-34, which is even more vulnerable.
* There will be a partisan unit appearing somewhere around Kursk. So, place several units west of it, that it cannot pass through.
* Use not just the good defense positions, but also remember on zone of control: if there are 2 hexes between your units, the enemy cannot pass through
* Let retreat space for the defending units. Surrendered units are gone...
The most important bastion places are:
- Tula, the hills and forest south of Tula,
- Voronezh, the hill west of Voronezh, the forest north of Izyum,
- Voroshilovgrad, the hill south of it,
- Rostov and the forest north of it,
- the 2 hills north of Izyum are also important to slow down the attackers but it can be given up (at least the northeastern one), if the situation get really bad.
I show now a few pictures. You can see the defense line. In the first 2 pictures, it is
the start of Axis turn 36. The blue numbers shows, how deep the given inf units have already dug in. Dug in units do not just later retreat, but they have higher survivability too. Deep dug-in panzergrenadiers will many times even not be attacked by the enemy. But that is random, so try to backup them with arty. The unit in Rostov cannot be backed up, but luckily, it will not be attacked mostly. But the unit in forest north of it has to be defended!
The second 2 pictures are
the end of Axis turn 40. The defense line is full, the Tiger is already present, the Stug just arrived.
What else?
- If you want to take the Caucasus (I had no time for it and do not needed it.), it is practical, that you take also Novorossiysk and hold it. It is not very hard: with an arty, some dug-in Mnt troops is enough. You can try, if you have already advanced to the direction of Grozny, to make a defense circle at Voroshilovsk. You can succeed, but it is a risky one and there will be casualties.
- Look the weather forecast and when it predicts better weather, place to bombers on possibly appear places of enemy armor. After that turn, fly away, other way, your bombers will be butchered! I also advise to stay only with the thoughest fighters in the fighting area, because the weaker ones will be also butchered. Use the AA's to weaken them and try not let any damaged Soviet airplane to get away.
- Look the weather forecast and when it shows the end of freeze, make plan, how to use it - many Soviet units will be stranded and easy prey. For example, it is a good tactic to lure/put the Soviet armor on river hexes, because when the snow melts...

Also try to reach the western shore of the river Don around Voronezh, because if you can, than you can close the way of the Soviet units and they can only cross through the river - and that will be much more defensible.
Good luck and write your experiences!
