In the conclusion of the battle, John-117 detonated the ''Pillar of Autumn''<nowiki>'</nowiki>s [[Fusion drive|fusion reactors]] in order to destroy the ring. The explosion critically damaged the superstructure below it; the resulting shockwave and damage to the ring's systems destabilized the ring, shattering it into pieces.<ref>'''Halo: Combat Evolved''', campaign level ''[[The Maw]]''</ref>{{Ref/Note|The particulars of Installation 04's destruction differ throughout its various depictions. In ''Halo: Combat Evolved'', ''Combat Evolved Anniversary'' and most [[terminal]] depictions, a portion of the ring next to the ''Autumn''<nowiki>'</nowiki>s explosion is sent flying to the other side where it bisects the ring, further splintering the superstructure. The most noticeable change is in the flashback portion of the level ''[[The Heretic]]'' in ''Halo 2: Anniversary'', where the fragment is no longer propelled to the other side and the ring simply shatters, with the explosions spreading in both directions of the epicenter in a chain reaction. The blue lights on the outer surface are also seen going out in this version. The [[Terminal (Halo 2: Anniversary)|''Halo 2: Anniversary'' terminals]] give two versions of the ring's destruction, the first (in Terminal 4) being identical to ''Halo: Combat Evolved Anniversary''<nowiki>'</nowiki>s [[Terminal (Halo: Combat Evolved Anniversary)|Terminal 11]], which is closer to the original ''Halo: Combat Evolved'' mechanics, although the ring's shattering is more violent. The second version, shown in Terminal 12, is closer in line with the depiction in ''Halo 2: Anniversary'' version of the flashback in ''The Heretic'' and lacks the shard being blasted to the opposite side.}}

Only a handful of humans and Covenant survived the battle. 343 Guilty Spark floated through space to a [[Threshold gas mine|gas mining platform]] over Threshold, where he stumbled upon a Covenant expeditionary force. Inspired by his words, they began a [[Sesa 'Refumee's heretic faction|heretical]] rebellion against the greater Covenant. Installation 04's destruction is seen as the first step in the chain of events that led to the [[Great Schism]]. The Heretics were quelled by [[Arbiter]] [[Thel 'Vadam]] who silenced their leader, but the seeds of a rebellion were planted. The Monitor was then captured by the loyal Covenant and later defected to the humans' side until he was destroyed on the replacement Alpha Halo by SPARTAN-117 with the help of Sergeant Johnson.
