 The reason Falkenhayn chose the Jiu Valley for a breakthrough was rather logistical than strategical.The consequences of the German breakthrough in that region during mid-November, serious as they were for the Romanians, proved less disastrous than those which would have followed upon an early breakthrough at the Bran/Törzburg and Predeal passes.In order for Falkenhyan to win a complete victory at the earliest possible moment, it was necessary to force the passes in the center of the Carpathian arc.
