By the 1700s, the Sioux had acquired horses and flourished as a tribe hunting buffalo on the high plains of Wisconsin, Iowa, and the Dakotas. Eventually, white settlers pushed west onto Sioux lands and multiple treaties were made and broken. Two of the eventual conflicts between soldiers and the Sioux were

A) Red Cloud's War and Little Bighorn

B) Sand Creek Massacre and Colorado War

C) Battles of Mud Springs and Rush Creek

D) Battles of Red Butte and Sawyer's Creek
