On February 13, 2526, the Covenant was detected by the UNSC Accra, roughly 18.5 million kilometers away from Bliss. The Bliss Defense Fleet consisting of the UNSC Weeping Willows, UNSC Matador, and the UNSC Purpose engaged the fleet of 45 Covenant warships near the moon of Aires. The UNSC battlegroup was presumably defeated as the Accra lost contact with the group roughly after 3 minutes after engaging.
The Covenant then moved in to glass the planet, with Manikata being one of the first places they struck. After this, the Covenant tracked down the UNSC Accra, which had moved to the other side of Bliss, and destroyed it.
On February 19, an ONI report was compiled from the info in the recorder.
At some point after the battle, an ONI Section Two emissary team was sent out to meet with several leaders in the Outer Colonies to discuss the Covenant. While initially highly skeptical of this threat, the leaders were more willing to hear the UNSC out when they saw footage and audio from the Accra.
