Nothing else happened for the rest of the day. Zula did not move much from the sofa. The three remaining soldiers took turns going out in pairs to explore the vicinity, but they couldn’t stay out for long because of the shortage of winter clothing. One was always left behind, presumably to keep an eye on Zula. Sometimes they came back with trophies scavenged from other buildings: tools, first aid kits, dead flashlights, worn-out hoodies, work gloves, pornographic magazines, bars of soap, cans of oil. The scavenging developed momentum as they found more warm things to wear. During the afternoon, they put considerable effort into moving snow away from a travel trailer that had been left parked about a hundred meters from the headquarters building. This had been visible yesterday as an anomalous snow drift. Now it was revealed as an Airstream trailer, Zula guessed between twenty and thirty feet long. It had been jacked up to take the weight off its wheels and a shed roof of corrugated fiberglass had been affixed to one side, creating a sheltered outdoor space that, when cleared of snow, proved to contain a picnic table and some lawn chairs. From its interior they scavenged more kitchen ware, blankets, a foam mattress, packets of instant coffee and quick-cook oatmeal.
