potlatch made their way into the interior. Seeking more furs to trade, the Tahltan also expanded their territory beyond the Stikine River basin into the upper Nass and Taku Rivers, leading to conflicts with neighboring tribes. In the 1830s smallpox, likely introduced via Russian ships and spread up the Stikine by Tlingit traders, killed more than half the Tahltan population. Over the next few decades, repeated waves of smallpox devastated Tlingit and Tahltan populations. At the beginning of the summer 1862 epidemic, numerous Tlingit were working or trading in Victoria, BC when the first cases were discovered. To prevent the spread of disease among the white population, the Tlingit were forced to return to their homelands in southeast Alaska, bringing smallpox with them. Smallpox ravaged the coast over the 1862 summer, killing some 60 percent of the Stikine Tlingit. Gold rush period Alexander "Buck" Choquette discovered gold on the lower Stikine in 1861, sparking the brief Stikine Gold Rush. More than 800 men departed from Victoria to the Stikine River, where they traveled into the interior on steamboats. The large influx of miners into the Stikine country, along with the businesses that supplied them with provisions, brought an end to Tlingit control of trade on the Stikine. Although not much gold was found on the Stikine, the Stickeen Territories were established to administer the region, and soon incorporated into the Colony of British Columbia. Prospectors continued to push deeper into the Stikine country over the next few years. In light of this and declining profits from the fur trade, Russia feared it would lose control of its North American colonies to Great Britain, and sold Alaska to the United States in 1867. The U.S. Army occupied Fort Stikine in 1868, renaming it Fort Wrangel. Military force was used to assert control over the Tlingit, preventing them from interfering with settlers, prospectors and traders headed to the interior. In 1866 the Western Union Telegraph Company sought to build a telegraph line connecting North America and Europe, crossing the Bering Strait and Siberia. In order to support construction through the BC interior, large bales of wire were shipped via steamboat to the Stikine's head of navigation, which became known as Telegraph Creek. After the completion of the transatlantic telegraph cable in 1867 the project was abandoned, though the name remained. At that point the telegraph had been completed as far north as
