which halo did offensive bias fire? since 5 of the 12 were already used to attack a forerunner city by mendicant bias.

In fall from grace mendicant bias was unable to "disable" halo's directly. But his intentions were to DISABLE, them from firing, and apparently OFFENSIVE BIAS was used to override him so that the Halos could be FIRED ultimately and they were but.. how many where fired? was this before or after Mendicant fired 5 of the 12 halos?
