Battle for Aurora
The UNSC Excalibur was stationed at Aurora for a small defence fleet to safe-guard the planet from the Covenant as the war began to escalate. The Covenant eventually discovered Aurora's location and mobilised a large invasion fleet to annihilate the human presence there. The small defence fleet, vastly outnumbered was mostly obliterated except for the Excalibur and the UNSC carrier Make It Rain, who were forced to retreat from the battle and regroup. During the battle, communications with the UNSC was disrupted and in an act of desperation, the UNSC frigate Sunshine retreated to a nearby star system to seek the combined help of the United Rebel Front in retaking the colony and establishing communications with UNSC HIGHCOM.
