Wouldn’t have southern Africa on my map (or I’d go the whole hog and have Asia and the Pacific as well), but if it is on there it might as well have tts worth fighting over.
By and large, the above list pairs up VCs across the main fronts vel:
London-Berlin (North Sea)
Paris-Essen (Western Front)
Rome-Vienna (Alpine Front/Adriatic)
Konigsburg-Petrograd (Baltic)
Lemberg-Kiev (Ukraine)
Brazzaville-Dar-es-Salaam (Central Africa)
Cairo-Damascus (Middle East)
Delhi-Baghdad (Mesopotamia)
Tiflis-Erzerum (Caucasus/Black Sea)
New York-Mexico City (Rio Grande Front)
Moscow-Constantinople (The Straits)
