The Cocopah also entered the Yuma War following the tax revolt initially on the side of the Quechan against the U.S. After making peace with the U.S., the Cocopah allied with the Paipai and Halyikwamai and turned against the Quechan, after accumulating tension between the two tribes. War broke out in May 1853, when the Cocopah besieged three Quechan villages holding them hostage. In retaliation, the Quechan-allied Mohave backed the Quechan and raided the Cocopah. The Yuma War came to an end when the U.S. threatened the Mojave that they would intervene on the side of the Cocopah.
