All of the native tribes experienced gradual disillusionment with the U.S. government because of its inability or unwillingness to honor its treaty commitments . The major leaders among the tribes was Wabasha and Little Crow among the Dakota Sioux , Flat Mouth and Hole @-@ in @-@ the @-@ Day among the Ojibwe , and Winneshiek among the Winnebago . The success of treaty negotiations between the U.S. and the tribes was in great part facilitated by the mixed race families such as the Faribaults and the Renvilles .
