A Covenant fleet is discovered by Ensign William Lovell on UNSC Remote Scanning Outpost Archimedes, entering the Sigma Octanus system. Commander Keyes, on board the UNSC Destroyer Iroquois, takes on 4 medium-tonnage Covenant craft (two Frigates, one destroyer, one carrier), and destroys 3 of them in what becomes known as the 'Keyes Loop'. The Carrier heads to Sigma Octanus IV and drops Covenant troops, invading the city of Côte d'Azur. Keyes is promoted to Captain by Admiral Micheal Stanforth. General Kits and his marines take on the Covenant invaders groundside.

18/7/2552
The Marines are massacred by a new type of Covenant: Hunters. Corporal Harland, Private Fincher, Private Walker, and Private Cochran evade Covenant attacks in a warthog and win a battle against two banshees. However, they return to Alpha Base, marine headquarters at Côte, and discover that most of the base is destroyed. Out of 1,600 marines, 14 remain. Even so, they have defeated a large amount of Covenant even though they were up against bad odds.

The Spartans and the Marines engage Covenant forces on the ground and discover some civilians that hid in cargo ships. After discovering a new breed of Covenant, engineers, they find some hunters stealing an artifact from a museum. The SPARTANS, civilians, and marines escape, eventually nuking Cote D'Azur and most of the Covenant invasion force. During this battle, 4 dozen UNSC ships engage 20 Covenant craft. Seven human craft survive. The Iroquois destroys a stealth ship receiving an encrypted transmission from the surface. Once this ship is destroyed, the surviving Covenant ships break off and flee. The Iroquois heads back to Reach for debriefing. A Covenant tracker attaches itself, unseen, to the Iroquois' hull.

30/8/2552
Cortana gets revenge on Colonel James Ackerson, part of ONI's Special Warfare branch, for attempting to eliminate Cortana and Master Chief - she gets him transferred to the front. Bypassing several other colonies, the Covenant arrive at Reach and begin what has become all too familiar to the embattled Human forces: the destruction of the planet. The Spartans are divided into two teams: Red and Blue. John and the rest of Blue team (Linda and James), while on an orbital mission to ensure that a NAV database stays out of Covenant hands, end up onboard the Pillar of Autumn when she jumps away from the Reach system to evade Covenant forces. James is lost and Linda is mortally wounded, and the subsequent mission on Halo is left to the Master Chief to complete. When the Master Chief retreats to the Pelican, he meets up with some marines: Private Jenkins, Private O'Brien, Private Bicenti, and Sergeant Johnson. The Covenant take the surface of Reach, and Red team splits, one group to retrieve Admiral Whitcomb, while the rest hole up in ONI's Castle Base underground facility with Dr. Halsey. The Spartans receive parts of a MJOLNIR Mark V upgrade and new weapons, while Dr. Halsey learns of Colonel Ackerson's mysterious plans, plans that seem to involve "her" Spartans.

Blue team joins with team Gamma to retrieve Admiral Whitcomb, and rejoin the rest of Red team who have been besieged by the Covenant, who apparently revere the artefact that the Humans have found.

The remaining Spartans, Admiral Whitcomb, Dr. Halsey, Sgt. Johnson, Lieutenant Haverson, Warrant Officer Polaski, and Corporal Locklear jump to Slipspace on board the Covenant/Human hybrid ship Gettysburg-Ascendant Justice, and discover that the shard seems to have the ability to bend both space and time.

12/9/2552
The Gettysburg/Ascendant Justice arrives for refit and provisioning in Eridanus system and meets with the rebels under Governor Jiles. Dr. Halsey sedates Spartan 087, Kelly, and absconds with her on Governor Jiles ship, a Chiroptera-class vessel, the smallest UNSC classification that contains an SFTE. Before she goes, she gives the alien artefact to Corporal Locklear, with implicit instructions to destroy it.

13/9/2552
In Operation: FIRST STRIKE Admiral Whitcomb and Lieutenant Haverson destroy the majority of the surrounding Covenant fleet by detonating the Unyielding Hierophant.
