I cannot get on the victory path when the tree branches off Stalingrad. I don't get the option to play Along the Volga. My only option is Escape from Stalingrad which is the losing path. As far as I know, I am capturing all victory and bonus hexes in Moscow and Stalingrad and have 28300 in prestige when Moscow falls, and 34200 when Stalingrad falls. I am playing on the beginner level. Do I needs to win those scenarios in a certain amount of turns?

There is a forum dedicated to the game where you can get an answer

You need to win the bonus objectives in Moscow as well, to later be able to access the winning path at Stalingrad.
