January 1925. The Arctic town of Nome, Alaska sat locked in polar darkness at the western edge of the continent, surrounded on three sides by frozen tundra and on the fourth by the ice-choked waters of the Bering Sea.
Nome was a gold rush town that had never quite let go of its rough edges. Its wooden storefronts and gravel streets were buried under four feet of packed snow, and the thermometer outside the Federal Building had read fifty-two degrees below zero for the past eleven days straight.
The pale grey light that passed for an Alaskan winter day lasted barely four hours. After that, the darkness returned — absolute, heavy, and cold enough to freeze exposed skin within thirty seconds. Dr. Curtis Welch pressed his stethoscope against the chest of a seven-year-old girl named Anna Kronblad, his face drawn tight with professional worry.
Anna lay on the examination table wrapped in a wool blanket, her throat swollen, her breathing labored, a thick grey-white membrane coating the back of her tonsils. Dr. Welch had worked through the afternoon without stopping. He had already checked six other children that morning who had presented with the same alarming combination of throat inflammation, swollen neck glands, and that unmistakable membrane.
Diphtheria. The word sat in his chest like a stone. He straightened up slowly and turned away from the child, keeping his expression neutral so Anna's mother would not read the alarm in his face. His hands were steady — thirty years of medicine had given him that — but behind his wire-rimmed glasses his eyes were grave and calculating.
He walked to the window of his clinic and looked out across the frozen harbor. The sea ice on Norton Sound had sealed Nome from the outside world in mid-November. The supply ships would not return until June, when the ice broke and the Bering Sea became navigable again.
The last aircraft capable of operating in these temperatures had been a two-seater biplane whose engine had seized solid during a test run three weeks prior. The pilot had confirmed that no aircraft in the region could be started below thirty degrees below zero, and the temperature had not risen above minus forty in weeks. Nome was an island in the ice. Completely cut off.
Inside his medicine cabinet, Dr. Welch found his remaining stock of diphtheria antitoxin — four glass ampules, each carefully labeled, representing the last of his emergency supply. He calculated quickly. Eighty thousand units total.
Under normal circumstances, a child with early-stage diphtheria required between ten thousand and twenty thousand units for effective treatment. That meant his entire stock could treat at best four or five children. He had already confirmed seven suspected cases. And diphtheria spreads fast in cold, crowded communities where children share enclosed spaces to stay warm.
By the time he finished his rounds that afternoon, Dr. Welch had found three more suspected cases, bringing the total to ten. He sat down at his telegraph machine, composed himself carefully, and began to tap.
Urgent. Diphtheria epidemic imminent in Nome, Alaska. Population of fourteen hundred at risk. Antitoxin supply critically low — eighty thousand units remaining, insufficient to treat more than four children.
Request immediate delivery of at minimum three hundred thousand units. Sea route impassable until June. Aircraft engines non-operational in current temperatures. No other available supply route visible.
Response needed urgently. Within six hours, the reply came back from the Alaska Territorial Governor in Juneau. A supply of three hundred thousand units of fresh diphtheria antitoxin had been located in a hospital storage facility in Anchorage. The rail line running north from Anchorage could move the serum as far as Nenana — a small interior town at the end of the line, 674 miles from Nome.
After Nenana, there were no roads, no railways, and no aircraft that could fly in these conditions. After Nenana, the only available route through the Alaskan wilderness was the historic Iditarod dog sled trail — a frozen corridor that cut through mountain passes, tundra river valleys, and across the open sea ice of Norton Sound before reaching the coast at Nome.
Nome's children had a chance. But that chance depended entirely on the sled dogs and the mushers willing to run them through the worst winter in recent memory. The Governor had already begun organizing a relay. Twenty mushers and their dog teams had been recruited along the trail, each covering a segment of the route.
A train was being loaded in Anchorage that same evening. It would reach Nenana in approximately twenty hours, at which point the first musher would receive the antitoxin and begin the relay. Dr. Welch walked out of his clinic into the biting cold.
His breath formed a heavy cloud that dissipated immediately in the dry, frigid air. He looked south toward the distant mountain ridgeline, dark against the fading grey sky. Somewhere out there on the frozen trail, the fastest dog teams in Alaska were about to be asked to do something that had never been attempted in these conditions before. Twenty mushers.
Twenty dog teams. One relay chain. 674 miles across the most hostile wilderness on the American continent.
And at the far western end of that chain, assigned the longest and most dangerous leg across the cracking sea ice of Norton Sound, was Leonhard Seppala — and his lead dog Togo. The temperature dropped another six degrees before midnight. Nome had never felt so far from the rest of the world.
