Others had blood pressures so low their pulses weren't palpable, their breathing the only evidence of life. Hand-scrawled evacuation priority tags were taped to their gowns or cots. The tags indicated that doctors had decided that these sickest individuals in the hospital were to be evacuated last.

Among them was a divorced mother of four with a failing liver who was engaged to be remarried; a retired church janitor and father of six who had absorbed the impact of a car; a WYES public television volunteer with mesothelioma, whose name had recently disappeared from screen credits; a World War II "Rosie Riveter" who had trouble speaking because of a stroke; and an ailing matriarch with long, braided hair, "Ma'Dear," renowned for her cooking and the strict but loving way she raised twelve children, multiple grandchildren, and the nonrelatives she took into her home.

In the early afternoon a doctor, John Thiele, stood regarding them. Thiele had taken responsibility for a unit of twenty-four patients after Katrina struck on Monday, but by this day, Thursday, the last of them were gone, presumably on their way to safety. Two had died before they were rescued, and their bodies lay a few steps down the hallway in the hospital chapel, now a makeshift morgue.

Thiele specialized in critical care and diseases of the lungs. A stocky man with a round face and belly, and skinny legs revealed beneath his shorts, he answered often to "Dr. T" or, among friends, "Johnny," and when he smiled, his eyes crinkled nearly shut. He was a native New Orleanian, married at twenty, with three children. He was a golfer and a Saints football fan. He liked to smoke a good cigar while listening to Elvis.

Like many of the hospital staff around him, his professional association with what was now Memorial Medical Center stretched back decades, in his case to 1977, when he had rotated at the hospital as a Louisiana State University medical student. A classmate would later say that Johnny Thiele had turned into the sort of doctor they all wished to be: kind, gentle, and understanding, perhaps all the more so for having struggled over the years with alcohol and his moods. When Dr. T passed a female nurse, he would greet her by name with a pat on the back and sometimes call her "kiddo."

Thiele had undergone part of his training at big, public Charity Hospital, one of the busiest trauma centers in the nation, where he learned, when several paramedics burst into the emergency room in close succession, to attend to the most critical patients first. It was strange to see the sickest here at Memorial prioritized last for rescue. At a meeting Thiele had not attended, a small group of doctors had made this decision without consulting patients or their families, hoping to ensure that those with a greater chance of long-term survival were saved. The doctors at Memorial had drilled for disasters, but for scenarios like a sarin gas attack, where multiple pretend patients arrived at the hospital at once. Not in all his years of practice had Thiele drilled for the loss of backup power, running water, and transportation. Life was about learning to solve problems by experience. If he had a flat tire, he knew how to fix it. If somebody had a pulmonary embolism, he knew how to treat it. There was little in his personal history or education that had prepared him for what he was seeing and doing now. He had no repertoire for this.

He had arrived here on Sunday. He brought along a friend who was recovering from pneumonia and was too weak to comply with the mayor's mandatory evacuation order for the city, which had exempted hospitals. Early Monday, Thiele awoke to shouts and felt his fourth-story corner office swaying. Its floor-to-ceiling windows, thick as a thumb, moved in and out with the wind gusts, admitting the near-horizontal rain. He and his colleagues lifted computers away and sopped up water with sheets and gowns from patient exam rooms, wringing out the cloth over garbage cans.
