===The Sentinel activation===

When [[Installation 04|Alpha Halo]] was destroyed, it emitted a signal that placed all other [[Forerunner]] installations in standby mode, including the Sentinels guarding the [[Sarcophagus|shield world]] located within the artificial world of [[Onyx]]. On [[2552#October|October 31, 2552]], the first of these Sentinels to awaken suddenly began attacking [[United Nations Space Command|UNSC]] forces on and near [[Onyx]]. Coincidentally, [[SPARTAN-III Gamma Company|Gamma Company]] was participating in the top honors exercise at the time.<ref>'''Halo: Ghosts of Onyx''', ''pages 117-120''</ref>

The Spartans piled onto the two Mgalekgolo. Kurt-051 was wounded. Will-043 killed one Mgalekgolo, that had been shot by Linda-058, in hand-to-hand combat but was in turn shot and killed by the second. The last Mgalekgolo was killed by Fred-104 with a [[M41 Surface-to-Surface Rocket Medium Anti-Vehicle/Assault Weapon|Jackhammer]] missile mainly for efficiency reasons, as it could take down a Mgalekgolo with one hit.{{Ref/Reuse|goo360}}

However, the main Covenant assault with hundreds of Sangheili, [[Type-26 Ground Support Aircraft|Banshees]] and Unggoy, was yet to come. Realizing it was futile for his diminished force to resist further, Kurt-051 ordered the survivors into the shield world while opting to remain behind to prevent the Covenant from reopening the portal. 'Mantakree ordered his troops to not fire upon the center of the chamber, while sending in Huragok with [[slipspace field shunt]]s to reopen the portal. With 'Mantakree approaching to finish off the wounded Spartan personally, Kurt-051 detonated two [[FENRIS nuclear warhead|FENRIS warheads]], killing himself and the entire enemy force in the antechamber as well as triggering the Sentinels of Onyx to "erupt" through the surface of the planet. With the portal closed, his comrades who had escaped into shield world were trapped, but unharmed.<ref>'''Halo: Ghosts of Onyx''', ''page 372''</ref>

===Destruction of Onyx===

With the shield world closed and gated, Onyx disintegrated into its trillions of component Forerunner Sentinels. The Covenant fleet, so recently victorious against the humans, were finally obliterated by the swarm of vigilant constructs. Only the {{UNSCShip|Dusk}} managed to escape alive and intact.<ref>'''Halo: Glasslands''', ''page 48''</ref>
