Zhang Qian opens the Silk Road
Unfortunately for Zhang Qian, the path to Yuezhi lands let him right through the Xiongnu's domain. He was captured almost immediately and held for 10 years. Luckily, captivity was fairly cushy for Zhang Qian: The Xiongnu leader gave him a wife and gradually grew to trust him.
Zhang Qian eventually managed to escape, along with his wife and soldiers. Despite a decade of delay, he didn't give up on his mission: He and his men skirted the northern edge of the Tarim Basin and traveled through what is now the Xinjiang province to modern-day Tajikistan. The Yuezhi turned out to be uninterested in fighting the Chinese emperor's wars, but Zhang Qian was impressed by their advanced agriculture and strong horses. He made his way back to Xi'an ⎯ getting waylaid for another 2 years by the Xiongnu in the process ⎯ to tell the emperor of the opportunities for trade across the border. These reports would eventually contribute to the opening of the great Silk Road, a series of overland trade routes between East and West.
Coronado seeks out a city of gold
Coronado took with him an army of hundreds of Spaniards and natives. They met and fought Pueblo Indians in what is now New Mexico and captured two native men, one of whom claimed that the fabled Cibola was farther north.
The expedition soon found itself tramping through the seemingly infinite grass of the Texas and Oklahoma panhandles. They faced a Great Plains hailstorm that ripped holes in their tents and dented their helmets. Eventually, they made it to a Wichita Indian village near what is now Lindsborg, Kan. To Coronado's chagrin, the only gold to be seen was the Indians' cornfields. He had his native informant executed and limped back to New Mexico, where he received a head injury after falling off his horse. He returned to Mexico, bankrupted by the two-year expedition, and died 10 years later in Mexico City.
Lewis and Clark map the American West
Lewis and Clark had a lot of help from native informers in finding their way, but the journey was still difficult. During their first year, they wintered in North Dakota, where they recorded temperatures of minus 40 degrees Fahrenheit (minus 40 degrees Celsius). The next spring, a fork in the Missouri River forced the expedition to split up and travel dozens of miles in both directions to determine the right route. In Montana, they had to portage their canoes and equipment 18 miles (29 kilometers), a process that took a month and subjected them to hailstorms, clouds of mosquitoes and the ever-present threat of grizzly bears. Soon after, they traversed Montana's Bitterroot Mountains, where game was scarce and the men had to shoot and eat three of their own horses.
In the end, Lewis and Clark would make it to the Pacific and back with all but one of their men, who died of appendicitis. Upon their return, they were acclaimed as heroes and eventually made governors of some of the new territories they had explored.
Napoleon invades Russia
By the time the army entered the city, there was little left to conquer. The Czar and many of the city's residents had fled, burning any items of value they had to leave behind. In mid-October, unable to wait any longer for a surrender that never came, Napoleon and his forces made their retreat.
They had waited too long. The snows came early that year, burying the grass that would have fed the army's horses. When the army passed villages, the desperate animals tried to feed on the thatched roofs of houses, but most starved quickly. Soon enough, the soldiers began to starve, too. In the subzero temperatures, many simply froze to death. Far more died from hunger or cold than were killed in battle. In the end, Napoleon's 400,000 to 600,000-man army was reduced to a ragged, pitiful force of 20,000.
The Donner Party gets stranded
Hastings, an early pioneer, had published a guide for other travelers in which he recommended the Hastings Cutoff, a trail through Utah's Wasatch Mountains and Great Salt Lake Desert. By 1846, Hastings had only traveled this route once, without the heavy wagons used by pioneer families. Nonetheless, he sent emissaries east with letters urging émigrés to follow his directions for a quicker trip to California.
Among the recipients of this letter was the well-to-do Donner family. Along with eight other families and 16 single men, the Donners decided to take Hastings' route. This turned out to be a very bad decision.
The trail was nearly impassible, forcing the men in the party to hack through undergrowth and move boulders to create space for the wagons. Once they made it through the mountains, the pioneers had to face the arid salt flats of Utah, where they lost 36 oxen, several wagons and multiple supplies. By the time they reached the Sierra Nevada Mountains, winter had closed in.
What happened next is well known: Stranded, the party ate their livestock down to the hide and bones. When the animal flesh ran out, they turned to their own dead. By the time rescue parties arrived in February and March, bodies littered the pioneers' camps. Of the 87 members of the Donner Party who entered the Wasatch Mountains together, only 41 finished the journey.
Stanley seeks out Livingstone
Stanley launched his 200-man expedition from the Zanzibar coast (part of what is now Tanzania) in 1871. His goal was Lake Tanganyika, a great lake on the borders of what is now Burundi, the Democratic Republic of the Congo, Zambia and Tanzania. Despite his lavish funding, Stanley soon found that overland travel in Africa was tough. His horse died from a tsetse fly bite within days, his porters began to desert (perhaps as a result of brutal treatment by Stanley) and disease plagued the expedition.
After eight months, Stanley found his quarry in a village in what is now Tanzania. The two may or may not have had the famous "Dr. Livingstone, I presume?" conversation ⎯ journalists in the Victorian era being prone to exaggeration ⎯ but they did explore Lake Tanganyika together before Stanley left Africa. Livingstone remained behind, and would die of malaria and dysentery two years later.
Fridtjof Nansen attempts to reach the North Pole
After 18 months of drifting, Nansen went to Plan B. On March 14, 1895, he and his shipmate Hjalmar Johansen struck out for the pole on skis, taking three teams of sled dogs and three sleds to carry their supplies. They were 400 miles (640 km) from the pole with only 30 days' rations, and the terrain soon became rough. The pair got closer to the pole than anyone ever had, but after about three weeks, they realized they would never make it without starving to death.
The men turned back, aiming for the Arctic archipelago of Franz Josef Land. They traveled for weeks before finding signs of life ⎯ seals, gulls and whales. But they didn't know where they were, and winter was closing in. They found a sheltered cove and passed a frigid, dull winter holed up in a shelter made of stones and walrus bones. That spring, they set out again, finally reaching Cape Flora at the southern tip of the archipelago. There, they met another group of explorers, who returned them to a civilization that had largely given them up for dead.
