Devotion

The Devotion was a Covenant vessel.

The ship was part of a Covenant group of ships that engaged UNSC forces. During the battle, Devotion was requested to cover Sacred Promise's dead zone. 1200 seconds away from taking position, Devotion was unable to prevent Sacred Promise from being hit again and subsequently crashing into a nearby moon. From the chatter heard on the radio, it could be inferred that Devotion crashed into Earth's moon, but that is highly unlikely.
