“By now confusion was beginning to sweep the German lines. Shortages were apparent everywhere and in everything. A critical lack of transport, an almost total absence of fuel, and roads thronged with refugees made large-scale troop movements almost impossible. This immobility was producing dire consequences: as units shifted position, their equipment, including precious artillery, had to be abandoned. Communication networks, too, were faltering and in some places no longer existed. As a result, orders were often obsolete when they reached their destinations – or even when they were issued. The chaos was compounded as officers arriving at the front to take over units discovered nothing to take over, because their commands had already been captured or annihalated. In some areas, inexperienced men, left leaderless, did not know exactly where they were or who was fighting in their flanks. Even in veteran outfits, headquarters were forced to move with such frequency that often the troops did not know where their command post was or how to contact it.”
