From Halopedia, the Halo wiki
When the Fleet of Particular Justice discovered a gas mine on Threshold that was distinctly Forerunner in origin, the Minor Prophet of Stewardship sent a retrieval team under 'Bandolee and Sesa 'Refumee to investigate it. Supreme Commander Thel 'Vadamee disapproved, believing that all Covenant forces should be concentrated on Halo until the UNSC presence was eliminated.
After the conclusion of the Battle of Installation 04, the retrieval team found itself marooned on the gas mine. While there, the group encountered 343 Guilty Spark, having arrived into the gas mine from the remains of Installation 04. Upon listening to his words and finding out the truth about the Halos and the Great Journey, Sesa 'Refumee led a rebellion and began broadcasting their beliefs across Covenant communications channels, attracting the attention of other Covenant personnel, including the Hierarchs. Declaring the movement to heretical, the High Prophets ordered Covenant Special Operations forces led by Rtas 'Vadumee and Arbiter Thel 'Vadamee to attack the mine and end the rebellion. It is presumed that 'Bandolee was killed during the battle, either by the Special Operations forces or by the Flood when they were released from their restraints by the heretics.
