Togo 

Leonhard Seppala had gambled with the crossing of Norton Sound and won. He had crossed during the daylight hours of January 31, 1925, and although he could tell a storm was coming, it wasn’t there yet. The northeast wind was at his back as he left the roadhouse at Ungalik and pushed his fast toward Shaktoolik. Seppala had come 170 miles in his three days on the trail and believed he had about 100 miles to go before meeting the serum in Nulato. Togo and the rest of the dogs were making good time, had good energy, and so far had had good trail conditions.

A few minutes out of Shaktoolik Seppala saw another sled stopped ahead of him on the trail. The dogs had apparently started after a reindeer that had run across the trail and were tangled and fighting in their harnesses. Their driver saw Seppala and began waving frantically. Seppala had no intention of stopping to help. Time was of the essence. the wind was blowing at Seppala’s back and he wanted to take advantage of it as long as he could. As he passed the other sled, though, the driver jumped over the morass of agitated dogs and ran at him, screaming, “The serum! The serum! I have it here!”

The stunned Seppala had not gotten word of the change in the plans for the relay and had no idea that the serum could have made the trip from the railhead at Nenana in just three days time. Such speed was unheard of. It was true, though. The other driver, Henry Ivanoff, a Russian Eskimo who captained a ship on Norton sound in the summers, had taken the serum from Myles Gonangnan at Shaktoolik. He had been on the trail only a few minutes when he encountered Seppala. It was mid-afternoon, and the few daylight hours had turned to dusk.

Ivanoff informed Seppala that the epidemic had worsened and that the governor had ordered teams to run with the serum round the clock until it got to Nome. Worried at the news, Seppala wasted no time turning around and heading back toward Ungalik, 23 miles away. He was to take the serum back across Norton Sound if it was safe to do so, or run along the shore to Golovin, where Charlie Olsen waited to take the serum on the next leg of the relay. He was still unaware that his only child, eight year old Sigrid, was now one of Dr. Welch’s patients.

Having crossed the sound in daylight, Seppala knew that the coming storm would wreak havoc on the ice, and now that he was heading into the wind he realized that the storm was coming quickly.He had to cross the sound before the ice broke up or he and the serum, and Nome’s diphtheria victims, might all be lost.

Seppala and Togo had crossed the sound a number of times, but one time in particular had to be preying on Seppala’s mind as he headed toward it. Togo had been leading his sled across the sound during a northeastern gale on another occasion when, a few miles from shore, Seppala heard an ominous crack that let him know the sea ice was breaking up. Togo headed toward shore even before Seppala could give the command, but drew up short so fast he nearly flipped backwards. A yawning chasm of water had opened almost at Togo’s feet, but the dog had reacted quickly enough to avert immediate disaster. Seppala looked around and realized with dismay that he and his team were trapped on an ice floe and headed out to sea.

They spent more than twelve hours on that raft of ice, waiting as it drifted in the icy waters. Finally it neared land, but ran up against another floe that was jammed against the ice still connected to shore. they stopped moving, but there was still a five foot gap of water that Seppala couldn’t hope to cross. He tied a lead onto Togo and heaved the dog across the water. Togo landed on the ice and sensing what Seppala intended, the dog began pulling with all his might, narrowing the gap between the two ice floes. Then the lead rope snapped. Seppala thought he was a dead man. Then Togo, showing himself to be possessed of more intelligence and resourcefulness than most men could expect from even their lead dogs, leaped into the water and grabbed the broken end of the lead rope in his jaws. He clambered back onto the ice and continued pulling until he had narrowed the gap enough for Seppala and the sled to cross safely.

Seppala knew that he would be trusting Togo completely to make a night crossing of Norton Sound in another northeastern gale. In the Arctic darkness, and in a blowing blizzard, Seppala wouldn’t be able to see to color of the ice or hear it creaking. He didn’t hesitate, though. When he reached the Ungalik he put his life, and the lives of Nome’s diphtheria patients, in Togo’s capable paws.

His trust was not misplaced. At 8:00 that evening, Seppala and Togo pulled back onto shore at Isaac’s Point. They had crossed Norton Sound twice in one day, traveling a total of 84 miles. Such a distance was incredible. They would rest at the roadhouse at Isaac’s Point until 1:00 a.m., then head out again. The next driver of the relay was waiting at Glolvin, another 50 miles away. As the dogs and the man slept, the ice in Norton Sound began cracking.

By the time Seppala hitched Togo and the rest of the dogs to the sled again, the wind was howling. An old Eskimo man warned Seppala not to go back out onto the ice of the sound, and Seppala would heed the advice for the most part. But unless he drove across the ice, the trail between Isaac’s Point and Golovin was extremely rugged. In fact, the current path of the Iditarod Race follows a different trail because of the dangers. Seppala’s route from Shaktoolik to Golovin was made even worse by high winds and temperatures of less than -40 degrees.

The ice Seppala and Togo had crossed just hours before had already begun to break up, so they also faced the constant threat of the ice breaking apart beneath them, even just a few yards from shore, and yawning chasms of open water. The howling wind blinded Seppala and, again in the darkness, he trusted Togo entirely. Once they crossed the last bit of frozen sound, Seppala had to be relieved, especially when he learned that by the time the sun rose the entire expanse where they had driven broke up completely.

Despite the potential hazards of the open ice, the most grueling portion of Seppala’s leg of the relay was about to begin. The team would have to climb eight miles along a series of ridges, including the 1,200 foot summit of a mountain called Little McKinley. Seppala’s hardy team was exhausted, but never stopped. They reached Little McKinley’s peak then descended three miles to the Golovin roadhouse, arriving thirteen hours after they had set out from Isaac’s point with only five hours of rest. Seppala and Togo and brought the serum 135 miles, and now, with the northeastern gale threatening even more, the serum was 78 miles from Nome and the dying children.

Charlie Olson took the Serum from Golovin to Bluff, where Seppala’s colleague, Gunnar Kaasen, was waiting with another team from Seppala’s kennels. Kaasen was to take the serum from Bluff to Port Safety after stopping to warm the serum at the Solomon Roadhouse. From Bluff, Ed Rohn was to take the serum into Nome.

None of these drivers knew how bad the storm was, though. Back in Nome, Dr. Welch was in worried conference with the public health officials. The mushers were carrying enough serum to treat 30 people, and 28 were already in Dr. Welch’s hospital. If the storm worsened and the serum was lost or frozen, all of those people would probably die. With the worsening storm threatening more than just the men on the trial, the decision was made to halt the relay until the storm had passed. Nome’s mayor could only guess where the serum was at this point, but it was almost a moot point since the telephone line only reached as far as Solomon. The mayor called the roadhouse at Solomon, where Kaasen was to rest and warm the serum, and gave the order that Kaasen should stop there until the storm passed. Word was also sent to Ed Rohn who was waiting at Port Safety, just 21 miles from Nome.

Kaasen hadn’t yet gotten the serum when the call went out, though. Charlie Olson had been hit with hurricane force winds on his leg of the relay and was making very slow time. At one point he was blown into a drift and had to dig his way out with his bare hands and then free the dogs. The fight against the wind and the blowing snow had exhausted him and he had not been able to warm himself up after digging out of the snow. When he arrived at the roadhouse at Bluff, Olson’s hands were so stiff with the cold that he couldn’t get the serum off the sled by himself. His dogs were nearly frozen, too. Their vulnerable groins were stiff with the ice and cold and the dogs limped into the roadhouse to get warm themselves. As they waited for the serum to thaw, Olson pleaded with Kaasen to wait for the storm to pass before heading out.

Kaasen was reluctant to wait. He had put together a team from Leonhard Seppala’s kennels, and believed that with the steady, strong Balto in the lead position he could make it. Balto was inexperienced as a lead dog on a run like this, and Seppala had left instructions that if another team needed to be put together his choice for the lead was a dog named Fox. Kaasen preferred Balto, though. He waited with Olson for a couple of hours. The storm showed no sign of abating. Kaasen went out at one point wearing sealskin mukluks, sealskin pants, a reindeer parka, and a second parks over that one. The wind pierced the furs, but Kaasen decided to head out anyway. He was afraid that if he waited the trail to Solomon and Port Safety would be blocked by drifts.

Just five miles from the Bluff roadhouse, Kaasen met his first drift. Balto tried to go though it but got mired in the snow. Kaassen couldn’t punch through the drift, either. Balto would have to find a way around. The dog was on an unfamiliar trail in the dark of night during a raging blizzard. He put his nose to the ground, though, and within a few minutes the team was running down the trail toward Solomon. A few miles further on the trail followed the frozen surface of the Topkok River. Kaasen was startled when Balto suddenly stopped and refused to go again. He realized that the dog had stepped into the water of a spot of overflow. Kaasen steered the team off the river and dried Balto’s paws, then ran them along the ridges toward Topkok mountain.

The storm was so bad by this point that Kaasen had no choice but to trust Balto to find his way along the trail. The man just held onto the sled and let the dogs do the work. It wasn’t until he recognized Bonanza Slough that he realized that he had completely missed the Solomon Roadhouse in the dark and the blowing snow. He was at least two miles past it. Rather than turn back, though, Kaasen decided to keep pushing toward Port Safety and the next leg of the relay. Because he missed the roadhouse, he never got the message that the health officials had ordered the relay halted to let the storm pass.

He started the dogs back on the trail through Bonanza Slough. The slough created a wind tunnel for the hurricane force winds of the storm. More than once the sled was literally picked up by the wind and the dogs became tangled in their harnesses. Each time Kaasen had to remove his gloves to right the sled and untangle the dogs. Then a particularly mighty gust picked up the team and tossed them all into a drift. Kaasen had to dig himself and the dogs out. He felt the bed of the sled for the serum. The box was gone! Panicked, Kaasen floundered around in the drift, finally locating it. He lashed it to the sled with extra straps this time and without further incident made it to Port Safety.

Believing that Kaasen would stay at Solomon, Ed Rohn had gone to bed at the Port Safety roadhouse. Kaasen considered waking him, but rejected the idea since Rohn’s dogs would have to be fed and then hitched to the sled for the continuing trip. It was about 3:00 in the morning, and Nome was about 20 miles away. Since leaving Bonanza Slough the storm appeared to be abating somewhat, so Kaasen decided to press on.

At 5:30 a.m. Gunnar Kaasen pulled into Nome with the serum. “Witnesses … said they saw Kaasen stagger off the sled and stumble up to Balto, where he collapsed, muttering: “Damn fine dog.”

Next: the Conclusion

Half an hour after Charlie Evans and his dead lead dogs had arrived in Nulato, the serum was thawed and Tommy Patsy, another Athabaskan driver with a formidable reputation for his wilderness survival skills, headed down the trail following the Yukon River to Kaltag, the last stop on the run before the trail rose into the Nulato Hills. He covered his 36 miles in about three and a half hours, making the best time of the entire relay at just over 10 miles per hour.

Jackscrew, a Koyukuk Indian, took the serum through the mountains from Kaltag to Old Woman Shelter. To lighten the dogs’ load and make better time on this difficult stretch of the trail, Jackscrew ran uphill through the woods of the Nulato Hills for a good bit of the first 15 miles of his 40 mile leg of the relay. Once he passed the Kaltag Divide and headed downhill toward Norton Sound, he climbed back aboard the sled.

Victor Anagick took the 34-mile leg from Old Woman Shelter to Unalakleet, across mostly open tundra and through the stunted coniferous taiga closer to the coast, where he passed the package to Myles Gonangnan, an Eskimo musher.

On the morning of Saturday, January 31, at Unalakleet on the southern shore of Norton Sound, Gonangnan took the measure of Norton Sound. He had to make the decision as to whether to cross it or go around it. The shortest route from Unalakleet would have been straight across Norton Sound to Nome. Leonhard Seppala had been warned against taking this route as it was entirely too risky. The center of the sound at this point rarely froze entirely because of the currents and motion of the water.

Norton Sound is an inlet of the Bering Sea. Nome, Alaska, sits on its north shore. The sound is about 150 miles long and about 125 miles across. Norton Bay is its northeast arm. The Yukon River, along which the teams of dogs drew their sleds carrying the precious diphtheria antitoxin serum in January 1925, flows into the sound from the south. The sound is only navigable from May to October. In October the sound begins to freeze as average temperatures dip well below freezing. By January, when the average temperature is below zero, the sound is completely frozen.

The closer you got to the sound, the more conscious you became that the ice was in a constant state of change and re-creation. huge swaths would suddenly break free and drift out to sea or a long narrow lead of water would open up…. Depending on the temperature, wind, and currents, the ice could assume various configurations – five-foot-high ice hummocks, a stretch of glare ice, or a continuous line of pressure ridges, which look like a chain of mountains across the sound. …

Then there was the wind. It was a given on Norton Sound that the wind howled and that life along these shores would be a constant struggle against a force that tried to beat you back at every step of every task. But when the wind blew out of the east, people took special note. These winds were shaped into powerful tunnels, and gusts barreled down mountain slopes and through river valleys, spilling out onto the sound at spectacular speeds of more than 70 miles per hour. The could flip sleds, hurl a driver off the runners, and drag the wind chill down to minus 100 degrees. Even more terrifying, when the east winds blew, the ice growing out from shore often broke free and was sent out to sea in large floes.

—The Cruelest Miles, pp. 195-196

The overland route was safer than crossing the sound even in the best conditions. Gonangnan considered the fact that the wind had been blowing for several days from the west, pushing the ice against the coast and raising the level of the ice in the sound and weakening it. Had the wind remained from the west, the decision would have been easier. Even if the ice broke into floes, it would be blown toward shore and a sled team could navigate safely along the floes to shore. With the shift in the wind’s direction, though, the ice was being blown out to sea. More disturbing was that the northeast wind was building in strength. A storm was coming and would be there soon. When it came, the ice would be likely to break up. He decided not to risk the shortcut directly across Norton Sound. He turned northeast, toward Shaktoolik.

On the other side of Norton Sound, at about the same time, Leonhard Seppala was facing south and facing the same decision as Myles Gonangnan. Although he had been told not to risk the crossing, he knew that the fastest way to get the serum in the hands of Dr. Welch was to go across that frozen expanse. In two days he had covered about 110 miles, and had 200 more to go before he got to Nulato where he believed the serum would be waiting. Word had not reached him that not only had the number of teams in the relay increased tenfold, but that the serum had passed Nulato 24 hours before and was just on the other side of the sound.

Seppala decided the time saved by crossing the sound was worth the risk. Doubtless he would have hesitated even less had he known that his own daughter, Seigrid, had been admitted to Dr. Welch’s infirmary that very morning with diphtheria. Five more children had died, and twenty-seven were in the hospital, and at least eighty were known to have been exposed. Nome’s epidemic was in full swing. What was worse, one of the diphtheria patients was the daughter of the owner of a roadhouse at Solomon, a small settlement near Nome. The girl had been helping to cook for guests at the roadhouse. The grim fear was that she may have unwittingly spread the disease beyond Nome.

Later that day, Dr. Welch was told that Myles Gonangnan had left Unalakleet. With great relief Welch sent a telegram to the Public Health Service saying that the 300,000 units of serum from Anchorage was expected by noon the following day, February 1. Dr. Welch was unaware that the weather was conspiring against his patients.

The trail between Unalakleet and Shaktoolik is windy even in good weather, but sometimes the winds can blow from the north at more than hurricane force, with temperatures well below zero and chill factors worse than minus one hundred. Winds like that create ground blizzards, white-out conditions in which a sled can flip and men and dogs can freeze trying to find each other.

As the wind rose on the souther side of Norton Sound, snow blew in deeper and deeper drifts. At last Gonangnan had to break trail for his dogs. Breaking trail consisted of walking back and forth across the trail in snowshoes, tamping down the snow until it was firm enough to hold the weight of the dogs. The trail breaking was a slow, laborious effort. In five hours, Gonangnan had made only 12 miles. He stopped at a fishing camp to warm himself and the serum. He knew he was still at least nine hours from Shaktoolik, and had extremely difficult terrain to cross.

Five miles further along the trail were the Blueberry Hills, where the team would have to climb a 1000 foot summit then descend again to the beach. Wind tunnels in this region were brutal enough without the addition of the storm Gonangnan knew was coming. From the fishing village to Shaktoolik there were no shelters, abandoned or otherwise. If the storm hit while he was on this stretch of trail, it would be unpleasant indeed.

The wind was vicious and unrelenting on the way up the Blueberry Hills. By the time the team reached the summit Gonangnan was blinded by whiteout conditions. He had no time to prepare when the team suddenly began its steep descent toward the dunes along the sound. He held on and held his breath for the next three miles, and made it safely down to the beach only to find that the wind was blowing at gale force and and the wind chill was at least -70 degrees. He rode the sled for another four hours, arriving at Shaktoolik at 3:00 p.m.

There was no sign of Leonhard Seppala. Where was the famous musher?

Next: Seppala, Togo, and Balto 

Newspapers had picked up the story of the epidemic early. As the tone of the telegrams between Nome and the outside world became more urgent, radio began to carry the story to an even broader audience. Winter storms swept across the continent as Nome waited for the serum, and people enduring zero degree weather on the East Coast were amazed at the determination and hardiness of the dog sleds driving through temperatures more than 50 degrees colder. The entire nation was transfixed by its radios, chewing its fingernails in hopes that the men and dogs could brave the blizzards and hurricane force winds of the Alaskan winter storms, cross an untrustworthy seasonal ice pack, and deliver the serum to the exhausted doctor and nurses as the number of victims reportedly rose with each passing hour.

On January 28, the exhausted and frostbitten Wild Bill Shannon handed the package over to a 20 year old Athabaskan musher named Edgar Kallands at Tolovana. Kallands made his five hour, 31 mile run to Manley Hot Springs under essentially the same conditions that had nearly done Shannon in. The temperature was -56 Farhenheit. When Kallands arrived in Manley Hot Springs, his gloves, with his hands inside, had frozen to the handlebar of the sled. “The roadhouse owner had to pour boiling water over the birchwood bar to pry him loose,” the Associated Press reported.

At Manley Hot Springs, the precious cargo was handed to Dan Green, who took it another 28 miles to Fish Lake, where another Athabaskan driver, Johnny Folger, took possession of it and got it to Tanana, another 26 miles closer to Nome. At each stop, just as the Anchorage doctor had instructed, the serum was warmed for fifteen minutes. From Tanana, Sam Joseph, also an Athabaskan Indian, took the serum another 34 miles to Kallands, the settlement named for the family of young Edgar Kallands. Titus Nikolai then transported the package 24 miles to Nine Mile Cabin, where he gave it to Dave Corning. Corning took it another 30 miles to Kokrines, then Harry Pitka took it the next 30 miles to Ruby. At Ruby, Bill McCarty took over and drove 28 miles to Whiskey Creek, where Edgar Nollner waited. Nollner delivered the package to his brother George at Galena, another 24 miles closer to Nome.

George Nollner took the serum 18 miles to Bishop Mountain. He arrived at 3:00 a.m. on Friday, January 30. He and his friend Charlie Evans, the next driver in the relay, sat in the relative warmth of the cabin. Like everyone else along the way, they were worried that the deep cold and the infrequent thawing of the serum would render it useless. The temperature at Bishop Mountain was -62 degrees Fahrenheit, and Evans had thirty miles to go to Nulato, the halfway point, where Leonhard Seppala expected to take possession of the precious serum and return to Nome.

Evans ran into trouble as he approached the convergence of the Koyukuk and Yukon rivers. Water had broken through the ice and the trail was covered with dangerous overflow. Overflow is caused when because of the pressure beneath the solid surface of ice, water breaks through in a gush, then continues seeping. Sheets of extremely slick, glacier-like ice result from the water flowing over the ice. An ice fog also develops at about -50, when the relatively warmer water vapor from the overflow turns to tiny ice crystals in the air. The ice fog Evans encountered was as high as his waist. He could no longer even see his dogs, much less the trail.

Eventually, a breeze began to blow that dissipated some of the ice fog. This was a mixed blessing, though, because with the breeze came a worse wind chill. Evans couldn’t get off the sled to warm himself with exercise. If he did, and the ice fog thickened again, he’d be lost, and the dogs would have gone on without him. Less than ten miles from Nulato, the unthinkable happened. Evans had two lead dogs he had borrowed for the run. First one collapsed and had to be loaded onto the sled, then the other collapsed. Evans hitched himself to the sled and led the team the rest of the way to Nulato. When he arrived about 10:00 a.m., both lead dogs were dead.

The serum had arrived at the halfway point in three days, the shortest time that distance had ever been traveled. Leonhard Seppala had expected to meet the serum in Nulato, but the Territorial governor had other ideas. On that Friday, January 30, ten days after Dr. Welch had confirmed diphtheria among Nome’s population, the death toll stood at five. Getting the serum to Nome as fast as possible was paramount.

Leonhard Seppala, who held the records for the fastest runs by dog sled, had set out from Nome on January 26 planning to travel a total of 630 miles. Traveling that distance without rest would be impossible and time was of the essence. Alaska’s territorial governor made the decision to add more drivers and dogs to the number making the relay. The idea was that the fresher the teams were, the faster they’d get the serum to Nome. All in all 20 drivers and their teams of dogs would be participating in the relay.

Seppala had already set out on the first 315 mile leg of his journey, though, and he was still the best one to take the serum across the pack ice of Norton Sound. Driving across the frozen sound would shave a full day off the time it would take to get the serum to Nome. There was no way to get word to Seppala, though, that the plan had changed. As drivers were called to participate in the relay they were told to keep a look out for Seppala and to hand the serum over to him when they saw him.

Next: Crossing the open ice of Norton Sound; and the canine heroes Togo and Balto

Leonhard Seppala and His Lead Dog, Togo

Getting the diphtheria antitoxin to Nome the fastest way possible was paramount. The lives of scores of people, if not the whole town, depended on it.

The original plan for dog sleds was for two teams to meet in the middle. One team would set out from the end of the railroad at Nenana, and the other would set out from Nome. They would meet in the middle, at Nulato, and the Nome team would return with the serum.

The logical choice for the team to make the round trip between Nome and the halfway point was Leonhard Seppala and his team of Siberian Huskies, led by Togo. Togo was 12 years old, which was somewhat elderly, but he had been Seppala’s lead dog for tens of thousands of miles across the Alaskan Interior. Seppala himself held records for races like the All-Alaska Sweepstakes. He had trusted Togo with his life more than once.

Togo had not originally seemed like lead-dog material. In fact, Seppala tried to sell him twice, but Togo kept finding his way back to Seppala’s kennels. When he was just eight months old, Togo had escaped the kennel and followed Seppala. Seppala couldn’t turn back to return Togo, so he let the pup run with the team. Togo finished that trip in the harness next to the lead dog, and Seppala realized that Togo had great potential.

Alaska’s territorial governor was familiar with Seppala’s speed records across the frozen expanse of Northern Alaska’s interior, but thought that the fastest way to get the serum to Nome was by a relay involving more teams – thus, no team would be driving exhausted, the dogs would at their fastest and freshest, and the serum would get to Nome where it was desperately needed that much faster. The governor sent a telegram to the US Postal Inspector in Nenana, who would have the closest official contact with the mushers. The Postal Inspector contacted the Northern Commercial Company, which actually hired the drivers of the dog sleds. The company notified drivers all along the route to be ready for a relay. They wouldn’t be getting paid for this run. It was a mission of mercy.

Twenty teams of men and dogs took part in the relay. Athabaskan Indians (native to the Alaskan interior), Eskimos (native to the Alaskan coasts), and US Postal Service mushers all participated.

Dogs and men are believed to have arrived in Alaska together, walking across the Bering Land Bridge. Although the people native to Alaska hunted other animals, the dog was their only domesticated species. Dog fur kept Eskimos warm, dog meat filled their bellies when there was no other source of food. Dogs were used for hunting, as beasts of burden, and as guides through the confusing white terrain. It is believed that the Eskimos first came up with the idea of hitching dogs to sleds. The Athabaskans of the interior did not use sled dogs until after white men came to Alaska.

Twenty-four hours after the crate of diphtheria antitoxin serum left Anchorage, Alaska, the temperature in Nenana, Alaska, at the end of the railroad, was fifty degrees below zero. Traditionally, when the temperature reached -38 degrees Fahrenheit, so cold that mercury froze in thermometers, neither man nor beast went out. Wild Bill Shannon set out from Nenana with his team of Malamutes in that searing cold for a fifty-two mile run over very rough terrain. Normally the 52 miles between Nenana and Tolovana, where the next team in the relay waited, took two days with an overnight stop in Minto.

The train from Anchorage arrived at 9:00 p.m. January 27, 1925. Despite being cautioned by the Nenana Postal Inspector to wait until morning to start the run to Tovolo, Shannon insisted upon leaving immediately. “People are dying,” he said. His attitude was the attitude of every driver in the relay.

The trail normally used by the dog sleds had been churned up by horses in the days before, so Shannon turned his team to run on the frozen surface of the Tanana River. The air over the river was even colder, and the danger of water breaking through the ice was ever-present. As time wore on, Shannon had a harder time warming his feet and hands. He began losing his focus. Suddenly Blackie, his lead Malamute, swerved, taking the sled in a new direction. Shannon nearly lost his grip on the sled and looked around in surprise at Blackie’s move. He saw a black hole in the ice – an area of open water that the team had narrowly missed. Thanks to Blackie’s canine perceptions and quick thinking, disaster had been averted. It would not be the only time along this relay that the serum was nearly lost. But for the wit and courage of the lead dogs, the serum would never make it to Nome.

The temperature continued to drop through the Arctic night. Shannon felt his extremities freezing and knew he had to take steps to get the blood circulating in his body. So, he took steps. He got off the sled and literally ran alongside the team. This helped for only a short time, and soon Shannon realized he was in real danger of hypothermia. By the time he reached Minto, the halfway point between Nenana and Tolovana, the outside temperature was -62 degrees. Four dogs had bloody muzzles from breathing the icy air, and Shannon’s face was black with frostbite.

After four hours of warming himself by the stove in Minto, Shannon set out for the remaining 22 miles of the run to Tolovana. He had to leave three of his dogs behind because they were too weakened by pulmonary hemorrhaging caused by the cold to continue. A fourth dog looked questionable, but Shannon decided to take him. If necessary, that dog could be unhitched from the team and ride the rest of the way to Tolovana. Shannon made it to Tolovana by 11:00 a.m. on January 28. It was -56 degrees Farhenheit when he turned the precious cargo over to Edgar Kallands, the next driver in the relay.

In Nome that same morning, Leonhard Seppala set out. He had 315 miles to travel to get to the halfway point at Nulato, then 315 miles back to Nome with the serum. On the way he had to traverse the questionable pack ice of Norton Sound. The Sound might be completely frozen or it might have ice floes that would kill him and his team. the shortest distance between Nulato and Nome lay directly across the Sound, though.

In the meantime, the number of confirmed cases of diphtheria in Nome were increasing by the hour. Although both the white and native populations obeyed the quarantine, the strain was extremely virulent and and probably infected the population well before the quarantine had been ordered. The diphtheria bacterium could live for weeks outside its human host on something as benign as a toy. The children of the area had all attended Christmas celebrations and had been in school and church prior to the quarantine.

Nome’s mayor contacted the territorial governor again, begging for relief by airplane. A little more serum, enough to treat perhaps five people, had been located in Juneau and was being sent by rail to Nenana to await the next mail run. It wouldn’t be enough.

Next: more dogs, and a nation holds its collective breath …

Diphtheria has now been largely eradicated in developed countries. In the US, for example, preschool children typically receive multiple doses of the DPT vaccine, which immunizes them against diphtheria, pertussis (whooping cough), and tetanus. Children who are not immunized, especially those who are in close proximity to other non-immunized children, are most prone to the disease, even in places where it was previously under control. For example, after the fall of the Soviet Union a lapse in enforcement of the immunization programs resulted in outbreaks in several its former states. In 1924, though, the children of Nome had not been immunized against diphtheria. Indeed, the vaccine had only been successfully tested the previous year for the first time. Antibiotics were not available to treat the disease until after World War II.

Prior to 1891, a child with diphtheria could be expected to die within a few days of falling ill. Diphtheria was a dreadful disease, highly contagious and had a mortality rate of nearly one hundred percent. Children are the most vulnerable targets of this bacterium, although it can infect and kill adults, too. In a single outbreak between 1735 and 1740 diphtheria killed as many as 80% of the children under 10 years of age in some New England towns.

In the 1880s a method of intubation was discovered that prevented victims from suffocating, but this method did not stop the toxic effects of the bacteria. The mortality rate fell to 75%, which was small comfort when the disease attacked a community.

In the 1890s, however, a Prussian physician, Emil von Behring, developed an antitoxin that did not kill the bacteria, but neutralized the toxic poisons that the bacteria releases into the body. The first Nobel Prize in Medicine went to Dr. von Behring for this discovery and the development of this serum therapy for diphtheria. It was this serum Nome so desperately needed.

Six of Nome’s children had died of diphtheria by January 22, 1925, the day the telegram was sent pleading for serum. Two days later, two more children had died, Welch had confirmed diphtheria in 20 children, and 50 more were at risk of contracting the disease because of exposure to sick siblings.

The only ground-based link to the rest of the world during the winter is the Iditarod Trail, an established mail route used by the mushers and their teams of dogs. The trail stretches 938 miles from Seward on the southern coast of Alaska, across several mountain ranges and the vast tundra of the Alaskan interior before reaching Nome, situated on an icy port just two degrees south of the Arctic Circle. Because the cockpits of airplanes were open in 1925, the only way mail and supplies could get to Nome was the dog sled.

Nome, Alaska, sits at the top of the world. In January, the coldest month of the year, temperatures hover in single digits much of the time. In late January 1925, though, a series of winter storms were blasting across northern Alaska, pushing temperatures 30, 40 and 50 degrees below zero. It was through these strong winds and driving snows, and through the perpetual twilight of the Arctic winter, that the dogs and their mushers would have to transport the serum.

It was decided that the serum would travel by train to Nenana, as far as the tracks could take it. A teams of dogs would meet the train and take the serum to Nulato, approximately half the distance between Nenana and Nome. Leonhard Seppala, a Norwegian musher based in Nome, would take delivery of the serum and transport it back to Nome. Seppala and his dogs were famous for having won races across the Alaskan interior, and it seemed logical that he should hurry the serum to Nome.

Now that there was a plan for transporting the serum, Dr. Welch waited to hear that sufficient serum had been located and could be sent to Nome. In the meantime, as more children and adults developed the gray membrane of diphtheria, Dr. Welch began administering the expired serum that he had on hand. Possibly the confirmed case that worried Dr. Welch the most was that of Nome’s school superintendent, who was also a teacher. Every child in the Nome area would have been exposed to diphtheria through him. Dr. Welch hoped that the million units of serum he had requested would be enough to treat the entire population.

News finally came that 1.1 million units of the serum had been located at hospitals along the west coast of the US, but it would take until January 31 for the serum to arrive in Seattle to begin the trek to Nome. The serum was gathered and began its trek north. Having confirmed diphtheria on January 20, Dr. Welch knew that if no serum arrived until well into February, it would be too late for many of the children of Nome.

A few days later, 300,000 units of serum were located at a railway hospital in Anchorage. It wasn’t enough to save the town, but it was a start. Anchorage’s supply of serum would reach Nome long before the serum being sent from Seattle. The serum was packed in as much cushioning as possible to protect it from the jarring of the sled. The doctor in Anchorage pinned a note to the blanket surrounding the crate of serum instructing the mushers to warm the serum for fifteen minutes at each stop along the trail. He delivered the crate to the railroad and sent it north to Nenana. The serum would arrive in Nenana on January 27, a week after little Billy Barnett had died of diphtheria.

Next: the dogs…..
