Which sioux leader stormed out of negotiations about fortifying the bozeman trail?

Chief Red Cloud was the Sioux leader who stormed out of negotiations about fortifying the Bozeman Trail. Chief Red Cloud stormed out of the conference vowing that he would make the Bozeman Trail run with blood. He demonstrated that Carrington was the "white eagle" that had come to build a road through the Sioux hunting grounds. The forts constructed by Carrington were soon under siege, and in the first few months, they were under attack where 154 whites were killed while 20 were wounded. Around 700 horses, cows, and mules were driven off during this period.
