resemblance to the "modern" warfare practiced by the Americans along European lines, using its vast advantages in population and resources. Many tribes avoided warfare and others supported the U.S. Army. The tribes hostile to the government continued to pursue their traditional brand of fighting and, therefore, were unable to have any permanent success against the Army. Indian wars were fought throughout the western regions, with more conflicts in the states bordering Mexico than in the interior states. Arizona ranked highest, with 310 known battles fought within the state's boundaries between Americans and the Natives. Arizona ranked highest in war deaths, with 4,340 killed, including soldiers, civilians, and Native Americans. That was more than twice as many as occurred in Texas, the second-highest-ranking state. Most of the deaths in Arizona were caused by the Apache. Michno also says that fifty-one percent of the Indian war battles between 1850 and 1890 took place in Arizona, Texas, and New Mexico, as well as thirty-seven percent of the casualties in the county west of the Mississippi River. One of the deadliest Indian wars fought was the Snake War in 1864–1868, which was conducted by a confederacy of Northern Paiute, Bannock and Shoshone Native Americans, called the "Snake Indians" against the United States Army in the states of Oregon, Nevada, California, and Idaho which ran along the Snake River. The war started when tension arose between the local Natives and the flooding pioneer trains encroaching through their lands, which resulted in competition for food and resources. Natives included in this group attacked and harassed emigrant parties and miners crossing the Snake River Valley, which resulted in further retaliation of the white settlements and the intervention of the United States army. The war resulted in a total of 1,762 men who have been killed, wounded, and captured from both sides. Unlike other Indian Wars, the Snake War has widely forgotten in United States history due to having only limited coverage of the war. The Colorado War fought by Cheyenne, Arapaho and Sioux, was fought in the territories of Colorado to Nebraska. The conflict was fought in 1863–1865 while the American Civil War was still ongoing. Caused by dissolution between the Natives and the white settlers in the region, the war was infamous for the atrocities done between the two parties. White militias destroyed Native villages and killed Native women and children such as the bloody Sand
