Question: What is the name of the battle fought in Montana, August 9–10, 1877, between the U.S. Army and the Nez Perce tribe of Native Americans during which Poker Joe served as trail boss and guide to the Nez Percé?
Context: The Camas Meadows Battle Sites, also known as Camas Meadows Camp and Battle Sites, are two sites important to the Battle of Camas Creek, fought August 20, 1877 between member of the Nez Perce tribe and troops of the United States Army.  The Nez Perce captured about 150 horses and mules from a campsite of the pursuing army, and for several hours besieged a detachment sent to recover them at a second site.  The two sites, each about 40 acre in size, are about 5 mi apart in Clark County, Idaho.  They were designated a National Historic Landmark in 1989, and are now part of Nez Perce National Historical Park, a collection of sites important in Nez Perce history. Big Hole National Battlefield preserves a Nez Perce War battlefield located in Montana, United States.  The Nez Percé fought a delaying action against the 7th Infantry Regiment (United States) here on August 9 and 10, 1877, during their failed attempt to escape to Canada.  This action, the Battle of the Big Hole, was the largest battle fought between the Nez Percé and U.S. Government forces in the five-month conflict known as the Nez Perce War.  In 1992 the park was made a part of Nez Perce National Historical Park, which consists of 38 separate locations in five different states, following the flight of the Nez Percé tribe from the U.S. Cavalry. The Nez Perce War was an armed conflict between several bands of the Nez Perce tribe of Native Americans and their allies, a small band of the "Palouse" tribe led by Red Echo ("Hahtalekin") and Bald Head ("Husishusis Kute"), against the United States Army.  The conflict, fought between June–October 1877, stemmed from the refusal of several bands of the Nez Perce, dubbed "non-treaty Indians", to give up their ancestral lands in the Pacific Northwest and move to an Indian reservation in Idaho.  This forced removal was in violation of the 1855 Treaty of Walla Walla, which granted the tribe 7.5 million acres in their ancestral lands and the right to hunt and fish in lands ceded to the government. Nez Perce , also spelled Nez Percé or called Niimi'ipuutímt, is a Sahaptian language related to the several dialects of Sahaptin (note the spellings, "-ian" vs. "-in").  Nez Perce comes from the French word, "pierced nose," although Nez Perce (who call themeselves "Nimipu" meaning "the people") did not practice nose piercing.  This may have occurred as a result of confusion on behalf of the French, as it was surrounding tribes who practiced this act.  The Sahaptian sub-family is one of the branches of the Plateau Penutian family (which, in turn, may be related to a larger Penutian grouping).  It is spoken by the Nez Perce people of the Northwestern United States. The Jurden Henry Elfers Barn and Field is a historic site located on the south bank of John Day Creek, .33 mi east of U.S. Route 95 and north of Lucile, Idaho.  The barn and field were the site of a raid by members of the Nez Perce tribe in 1877.  White settlers had forced the Nez Perce to live on a reservation at Lapwai, and a group of young men from the tribe sought revenge against the settlers.  The men raided several sites along the Salmon River, including the Elfers' ranch.  During their raid on the ranch, the Nez Perce killed Jurden Henry Elfers, his nephew Henry "Harry" Burn Beckrodge, and hired worker Robert Bland, who were working at the barn and field at the time.  The men also stole several horses and a rifle from the property.  The raid was one of the main causes of the Nez Perce War, as soldiers at Fort Lapwai responded to the raids by attacking Chief Joseph's camp.  The barn and field are one of the few surviving sites connected to the events leading to the start of the war. Looking Glass ("Allalimya Takanin" 1832- 1877) was a principal Nez Perce architect of many of the military strategies employed by the Nez Perce during the Nez Perce War of 1877.  He, along with Chief Joseph, directed the 1877 retreat from eastern Oregon into Montana and onward toward the Canada–US border during the Nez Perce War.  He led the Alpowai band of the Nez Perce, which included the communities of Asotin, Alpowa, and Sapachesap along the Clearwater River in Idaho.  He inherited his name from his father, the prominent Nez Percé chief Apash Wyakaikt (“Flint Necklace”) or Ippakness Wayhayken (“Looking Glass Around Neck”) and was therefore called by the whites "Looking Glass". The Battle of the Big Hole was fought in Montana, August 9–10, 1877, between the U.S. Army and the Nez Perce tribe of Native Americans during the Nez Perce War.  Both sides suffered heavy casualties.  The Nez Perce withdrew in good order from the battlefield and continued their long fighting retreat that would result in their attempt to reach Canada and asylum. The Nez Perce in Yellowstone Park was the flight of the Nez Perce Indians through Yellowstone National Park between August 20 and Sept 7, during the Nez Perce War in 1877.  As the U.S. army pursued the Nez Perce through the park, a number of hostile and sometimes deadly encounters between park visitors and the Indians occurred.  Eventually, the army's pursuit forced the Nez Perce off the Yellowstone plateau and into forces arrayed to capture or destroy them when they emerged from the mountains of Yellowstone onto the valley of the Yellowstone River. Poker Joe (18??  - 1877) or Hototo, also known as "Lean Elk" or "Little Tobacco" was a warrior and subchief of the Nez Percé tribe of Native Americans who played a critical role during the flight of the Nez Percé during the Nez Percé War in 1877.  He was of half French Canadian and Nez Percé descent and was said to have received his nickname from his love of the game of poker.  Poker Joe was familiar with Montana and the routes through the Rocky Mountains to reach the Great Plains and guided the Nez Percé in their flight.  He spoke good English and served as an interpreter and adviser to Chief Joseph and other Nez Percé leaders.  He was the chosen trail boss and guide of the Nez Percé people following the Battle of the Big Hole, in which the Nez Percé won a costly victory against pursuing U.S. forces in southwest Montana.  He kept the Nez Percé ahead of the army for the following seven weeks.  He led the Nez Percé on a trek to the Missouri River, covering between 500 and 700 miles. Tuekakas, commonly known as Old Chief Joseph or Joseph the Elder (c. 1785-1871), was a Native American leader of the Wallowa Band of the Nez Perce.  Old Joseph was one of the first Nez Percé converts to Christianity and a vigorous advocate of the tribe's early peace with whites.  In 1855 he aided Washington's territorial governor and set up a Nez Percé reservation that expanded from Oregon into Idaho.  The Nez Perce agreed to give up a section of their tribal lands in return for an assurance whites would not intrude upon the sacred Wallowa Valley.
