In HW2 banished were on the arc. But they were not in battle of the arc i.e halo 3. Were they hiding there ,waiting for the day/fight to end?..
"For a decade, the Banished were little more than raiders and pirates, conducting surgical raids against the Covenant and other targets while gathering mercenaries to their cause. Evading Covenant enforcers led to Atriox prioritizing stealth in his forces".
"During the Covenant's reign, the Banished mostly laid low and kept on the move, never claiming territory; Atriox only attacked targets he had something to gain from, largely in the form of supplies and materiel".
I got this from https://www.halopedia.org/Banished, not sure if it's a reliable source or not. But yeah, I guess they were just kind of hiding and laying low, until the Covenant fell.
