On January 9, 1918, in Southern Arizona near the border with Mexico at a place called Bear Valley, one of the last battles of the American Indian Wars (1540-1924) was fought. A force of about 30 US Army cavalry soldiers of the 10th Cavalry Regiment shot it out with a force of about 30 Yaqui warriors, making this battle one of the last battles of the American Indian Wars fought between the mainly European settlers of what is now the United States and the Native Americans that originally lived in North America. Only the Posey War in 1923 in which 2 Native Americans were killed (with no White casualties) in Utah as Ute and Paiute tribes people were attacked by Mormon Utah residents while the tribes fled to Navajo Mountain and the end of the Renegade Period and Apache Wars in 1924 (note: the Mexican side of the Apache Wars continued until 1933) happened after the Battle of Bear Valley, although some sources list Bear Valley as the site of the last battle. (Depending on how “battle” is defined.)
