Mochi ("Buffalo Calf"; c. 1841 – 1881) was a Southern Cheyenne woman of the Tse Tse Stus band and the wife of Chief Medicine Water. Mochi, then a 24-year-old, was a member of Black Kettle's camp and was present on the morning of November 29, 1864, when John Chivington and over 650 troops of the First Colorado Cavalry, Third Colorado Cavalry and a company of the 1st Regiment New Mexico Volunteer Cavalry attacked Black Kettle's winter camp at Sand Creek on the plains of eastern Colorado Territory (referred to as the Sand Creek Massacre). During the unprovoked attack, Mochi witnessed her mother being shot in the forehead and killed by a U.S. soldier who had entered their tipi. According to her account, he then attempted to rape her, prompting her to shoot and kill him with her grandfather's rifle. She then fled the camp with the other survivors trying to evade Chivington's men. After the massacre, she became a warrior and engaged in raiding and warfare for the next 11 years. Mochi fought alongside her husband in numerous battles and raids and was the only Native American woman to be incarcerated by the United States Army as a prisoner of war.

Oliver Francis Short, who had fought in the Union Army during the American Civil War. Short, his 14-year-old son Truman, and four other members of the party were killed, with three of them being scalped. German family massacre On the morning of September 11, 1874, in Kansas, Chief Medicine Water and his band, including Mochi, attacked John German and his family as they were breaking camp. The family had camped along the stagecoach route which followed the Smoky Hill River while en route to Fort Wallace. German, his wife Liddia (Cox), son Stephen Wise, and daughters Rebecca Jane and Joanna Cleveland were killed and scalped, with Mochi killing Liddia with a tomahawk blow to the skull. After plundering the camp and setting fire to the wagon, the band took German's four youngest daughters captive. They were Catherine Elizabeth, age seventeen; Sophia Louisa, twelve; Julia Arminda, seven; and Nancy Addie, five. Julia and Nancy were traded to Grey Beard's band and were liberated after an
