Battle of Alluvion

Battle
Covenant scouting patrols located Alluvion in 2541, signaling a full-scale invasion one year later, in 2542. The UNSC managed to defend Alluvion with a substantial military force, keeping the enemy at bay for weeks, before a Covenant support fleet arrived, severing critical support lines and glassed major population centers and spaceports, leaving few survivors in its wake. By early 2544, no record of human activity remained on Alluvion.
