At Hannay's suggestion, von Schwabing is sent to the front to see battle, while the others head to Paris, just as the Germans begin a mighty attack. As they near the front, they hear the defenses are crumbling beneath the onslaught, with Hannay's men at the heart of things. He resumes his command, and holds a thin line against the German advance, with Wake running messages for him, Blenkiron engineering the reserve trenches and Mary nursing in a nearby hospital. Amos and Hamilton guard von Schwabing, whose mind has gone strange.
