'Civilization V' strategy: Pocatello's land-snatching Shoshone

Only a few more civs to go in my series of strategy posts about Brave New World's new civilizations. Next up is the land-snatching Shoshone lead by Chief Pocatello.

The Shoshone are a group of native Americans that originated in the rocky regions of western North America (now Nevada and Utah). Around the same time as European colonists began settling on the east coast, the Shoshone began expanding eastward, which brought them into conflict with other plains indians such as the Blackfoot, Crow, Lakota, Cheyenne, and Arapaho. Some Shoshone who migrated into Texas and Oklahoma would break off into their own tribe: Comanche, who would become expert horsemen. The Shoshone began to come into conflict with the United States in the late nineteenth century due to the U.S.'s westward expansion, leading to a massacre of as many as 500 Shoshone at a winter encampment at Bear River in 1863. Shoshone culture has survived on reservations to this day, and in 2008, began working with Utah and Idaho state leaders to create a memorial to the Bear River Massacre. At its height, the Shoshone nation was composed of many tribes that occupied vast territory, extending from modern-day Montana all the way through Nevada; and their offshoot tribe, the Comanche, exhibited strong control of Texas and Oklahoma.

As westward immigration lead to conflict between the Shoshone and United States, Chief Pocatello (or, Tondzaosha) lead his tribe in raids and attacks against settlers in Idaho along the Oregon trail. He was feared and respected by his enemies, and Brigham Young (leader of the Mormons) attempted to offer terms of appeasement to the Shoshone in order to stop the attacks. Instead, the United States army arrived and destroyed any chances of a peaceful solution. Despite the overwhelming might of the U.S. army, Pocatello avoided the total massacre of his people and eventually negotiated the Fort Bridger Treaty of 1868, which granted the Shoshone a permanent reservation at Fort Hall near the Snake River in exchange for annual compensation from the United States (which the United States rarely honored in full). Due to this agreement, the Shoshone cultural identity survives to this day, and the city of Pocatello in Idaho is named in his honor.
