Turn 94 and AGC has finished clearing the far bank of the Tsna river, leaving apparently very little Soviet opposition between it and the Volga. Again, the limiting factor here is supplies: my spearheads are already operating overextended, and while for now they haven't burned up all their supplies and so aren't suffering unduly from it, I can't continue a full-blooded offensive under these conditions. My advance will slow down considerably if the Soviets are able to oppose me with more than just scraps, until such a time as the railhead can be brought forward.
Speaking of railheads, this is how far they have to travel:
Karelian Group to Archangel: 34 hexes
AGN to Archangel: 73 hexes
AGC to Kazan: 61 hexes
Army Group B to Saratov: 43 hexes
Army Group A to Baku: 99 hexes
The Autumn mud period is due on turn 136 (another 42 turns) at which point everything off the rail net will be "overextended" and so I will need to pull most of the army back to the rail on or before that time. Typically, I'm repairing two hexes a turn on each route (except for the Karelian group where it's already at the front and can't be brought forward except after each Soviet position is cleared): at this rate the railhead will still be about 15 hexes short of Baku by turn 136. Once each objective is taken or nearly taken I'll begin drawing rail repair units off to the Caucasus Front but it's going to be tight. If I can accelerate the rail repair in the south to three hexes a turn from about turn 115 then that will do it. I should be able to add one more RR repair unit to the south in the next few turns as the Finnish rail net's connection to AGN is almost complete.
Clearly Georgia is going to have to wait as I have no excess capacity to push a rail line down the Black Sea Coast. However I'm not too concerned about this as the Caucasus Mountains should serve as a very defensible frontier to the south; I'd be a bit more concerned about an attack on the long northern front across the Steppe, especially if this threatens the rail link to Baku; ideally I would like to push a screen up to the Volga River but again I wouldn't be able to support this with a rail line. I had wanted lateral rail links to connect the fronts, too.... maybe in the Autumn?
