As the look of turn 6 shapes up it is apparent it is a race against time to take Poltava before these Russian units are cut off and out of supply. Operation Fredricus was unleashed on turn 5 and the Russian southern front line evaporated and Panzer spearheads cut straight to the Donets River. The German's historical result of bagging the whole Russian offensive and annihilating it is clearly evident on the game board!
You can see the video here. The live stream scheduled for tomorrow morning where I finish the rest of the game (turns 6-10) is found here.
