Timeline of the Battle for Zeta Halo
From Halopedia, the Halo wiki
This is a timeline of the events during the Battle for Zeta Halo. Fighting initially began on December 12, 2559 and has proceeded to June of 2560. Events on Installation 07 coincide with several Post-Covenant War conflicts including the Battle of Earth (2559), Battle of Boundary, Battle of Suban, and the Battle of Nysa.
December 12, 2559[edit]
- A Banished fleet led by Atriox arrived at Installation 07 and began building fortifications on the ring.[1]
- A fleet of UNSC vessels led by the UNSC Infinity is ambushed by Banished forces over Installation 07.[2] The Weapon is deployed to the ring.[3] Captain Thomas Lasky orders all hands to abandon ship.[4]
- John-117 engages Atriox in a hangar onboard the Infinity and is thrown into space. The ship is presumed destroyed.[5][Note 1]
- The surviving Infinity crew make landfall on the ring. Fireteam Taurus disables two Banished Kywasky Workshop Gorespike cannons in an area south of the Silent Auditorium.[6][7]
December 13, 2559[edit]
- In an effort to stop the Banished from taking control of the ring, Cortana detonates an explosion from the Silent Auditorium, fragmenting Installation 07 and killing herself and apparently Atriox in the process.[1][8] Various UNSC survivors on the ring's surface attempt to escape the destruction. Cortana's explosion unwittingly levelled the playing field in the fragmented section of the ring by taking out the third and last Banished Gorespike cannon.[7]
- During the destruction event, Cortana initiated an emergency translocation protocol. Installation 07, along with the debris from the space battle, were transported away from the Ephsu system to an unknown location[9][10] in a different star system[11] in uncharted space.[12]
December 15, 2559[edit]
- Spartan Vedrana Makovich discovers the crash site of the UNSC Mortal Reverie and determines it to be a viable location for the UNSC's base of operations.[13]
January 20, 2560[edit]
- Spartans Bonita Stone and Nina Kovan scout out the Banished territory Red Zone,[14] deducing a potential vulnerability of the enemy in that infighting is encouraged. They deduced that only Escharum's leadership keeps them in check.[15]
January 23, 2560[edit]
- Spartan Hudson Griffin leads Spartans Panago, Malik, and Sarkar on a mission to assassinate Escharum.[16] Spartan Bertold Vettel takes over his place and joins Commander Etana Hensler to lead the forces at the Reverie.[17]
January 30, 2560[edit]
- Spartan Griffin's team is ambushed by Escharum and all are killed except for Griffin. Escharum taunts him of his team's demise and of the Banished's impending assault on the Mortal Reverie. Griffin is able to send out an encoded message, warning the UNSC survivors at the Reverie.[18][17]
- The survivors at the Reverie receive a part of Griffin's transmission and prepare for an assault by the Banished.[19][17]
January 31, 2560[edit]
- Banished Jiralhanae Chieftain Tremonius and Captain Arthoc gathers a massive Banished assault force at Riven Gate.[20] Spartan Stone and Boulder Squad conduct a recon sweep at Riven Gate. Stone reports her findings to Mortal Reverie, and warns the Reverie that the Banished would arrive by nightfall.[21]
- The UNSC survivors at the Mortal Reverie prepare for the Banished assault. Spartans Makovich and Vettel discuss the UNSC's inability to win the upcoming battle and their dwindling options for the future.[22]
- Banished forces arrive at the Reverie and begin their assault on the wreckage.[23]
February 2, 2560[edit]
- The Reverie's starboard side sustains heavy damage and its Rampart point defense guns are destroyed; Banished air units overwhelm UNSC forces.[24]
- Spartan Vettel orders the UNSC survivors to retreat from the Reverie under the Banished assault.[25&#
