By disengaging completely and retreating, you show great power and restraint. Your enemies are desperate for you to react; retreat infuriates and provokes them into further attack. So keep retreating, exchanging space for time. Stay calm and balanced. Let them take the land they want; like the Germans, lure them into a void of nonaction. They will start to overextend themselves and make mistakes. Time is on your side, for you are not wasting any of it in useless battles.
