__NOTOC__
==Background==
===2462===
Covenant space: The Unggoy Rebellion begins and ends, ushering the Covenant Empire into the Twenty-Third Age of Doubt. The interim Hierarchs of the Thirty-Ninth Age of Conflict are replaced by the High Prophetess of Obligation and High Prophets of Restraint and Tolerance. 
===2490===
UEG space: The Insurrection begins, resulting in a major build-up of human military forces. Several of the programs and technologies launched in response to the Insurrection will prove crucial in the conflict with the Covenant, most notably the SPARTAN-II Program and the Magnetic Accelerator Cannon. 
===2513===
UEG space: The Colonial Military Administration suffers a mass defection in personnel and equipment to several insurrectionist entities; the United Nations Space Command subsequently dismantles the CMA and attempts to purge its insurrectionist sympathies. The UNSC moves aggressively against various rebellions, dealing with the perceived treachery of the CMA with extreme force. While undeniably effective, the retaliatory attacks negatively affect the public image of the United Nations Space Command in the outer colonies. 
===2515===
UEG space: A much-reduced Colonial Military Administration returns to service under the authority of the United Nations Space Command. This "New CMA" still serves to improve relations between colonials and the UNSC, but is only partially successful. Outer colonies remain generally opposed to permanent or temporary long-term military garrisons or defense fleets. 
===September 2524===
3 September 2524
UEG space — Epsilon Indi system perimeter: Covenant missionary ship Minor Transgression attacks and loots the unmanned Human freighter Horn of Plenty, after the freighter suffers a slipspace drive malfunction and reverts to real space. Covenant forces seize the freighter's navigation computer and destroy Horn of Plenty; Minor Transgression moves into the Epsilon Indi system. 
===December 2524===
22 December 2524
UEG space — Epsilon Indi system: Covenant missionary ship Minor Transgression captures the human freighter This End Up, and inadvertently kill its sole crew member. The Minor Transgression destroys the damaged human ship and proceeds further towards the Human colony world of Harvest.

===January 2525===
17 January
Covenant Space — High Charity: Notification of the recent findings of the Minor Transgression are successfully transmitted to the Ministry of Tranquility. Vice Minister of Tranquility Lod Mron intercepts the report and, realizing its implications, dispatches the Covenant light cruiser to the Epsilon Indi system. Notably, the Rapid Conversion is the only cruiser in the Covenant Navy commanded and crewed by Jiralhanae.
Epsilon Indi system: Human and Covenant forces engage in a brief skirmish aboard the human freighter Bulk Discount, resulting in the destruction of the Covenant missionary vessel Minor Transgression. Two Covenant personnel escape the vessel's destruction, however.
18 January
Covenant space — High Charity: Vice Minister of Tranquility Lod Mron and Minister of Fortitude Ord Casto enter into a conspiracy to hide the discoveries of the Minor Transgression in a bid to unseat the current leadership of the Covenant.
Epsilon Indi system - Harvest: Human sloop is dispatched to Reach requesting immediate military deployment to Harvest, against the wishes of the colonial government. It arrives on March 4. 
===February 2525===
3 February
UEG space — Epsilon Indi system: Covenant light cruiser Rapid Conversion enters the Epsilon Indi system and recovers survivors from the Minor Transgression. The Rapid Conversion is detected at extreme range by the human space station Tiara orbiting Harvest. 
7-10 February

— Harvest: Preparations are made on Harvest in anticipation of alien forces, both diplomatic and military in nature. 
11 February
UEG space — Epsilon Indi system - Harvest: Covenant forces deploy from the light cruiser Rapid Conversion, meeting with human representatives in Harvest's sizable Botanical Gardens. Negotiations fail and result in immediate violence, inadvertently initiated by low-ranking Covenant personnel. Both sides suffer minor casualties, and Covenant forces withdraw from the Gardens. The Human-Covenant War unofficially begins. 
*Participants of the failed negotiations on Harvest include: Planetary Governor , Lieutenant Commander , Marine Captain (wounded), Planetary Attorney General (killed), and Covenant Chieftain of the Jiralhanae .
Chieftain Maccabeus consults with Unggoy Deacon Dadab concerning the findings of Rapid Conversion's Luminary and transmits a report to the Vice Minister of Tranquility indicating the discovery of an Oracle. 
11-21 February
UEG space — Epsilon Indi system - Harvest orbit: Covenant forces move to high orbit and remain effectively inactive for ten days, awaiting further orders from High Charity. 
15-21 February
UEG space — Epsilon Indi system - Harvest: Planet-wide broadcasts are made requesting the population of Harvest to relocate to the capital city of Utgard, due to the failure of negotiations following first contact. Most do not adhere to this request.
20 February
Covenant space — High Charity: Co-conspirators Lod Mron and Ord Casto visit the Forerunner Keyship at the heart of High Charity as a formality following their blackmail of the High Prophet of Restraint. While there, they inadvertently trigger a response from the Keyship's intelligence, which identifies Humanity as its makers. Philologist Hod Rumnt joins the conspiracy and the trio agrees to keep secret their discovery in order to preserve the Covenant. Lod Mron transmits orders to Rapid Conversion to exterminate the population of Harvest and denying the discovery of an oracle. 
21 February
UEG space — Epsilon Indi system - Harvest: Covenant forces deploy to the Tiara, effectively severing Harvest's interstellar communications; light cruiser Rapid Conversion continues into Harvest's atmosphere and begins destroying outlying human structures near the settlement of Gladsheim. 
22 February
UEG space — Epsilon Indi system - Harvest: Rapid Conversion destroys hundreds of remote human residences, killing approximately 3,000 people. Gladsheim is successfully evacuated, however, and intervening Covenant forces are repelled. Following the destruction of the (abandoned) city of Gladsheim and outlying residences, the people of Harvest quickly adhere to a renewed planet-wide evacuation request and gather at Utgard. 
23 February
UEG space — Epsilon Indi system - Harvest: Human forces launch a tactical strike against Covenant forces on the Tiara space station and overwhelm them; simultaneously, Harvest's mass driver is utilized to effectively disable the Rapid Conversion. Despite militia casualties and the loss of more than 20,000 civilians, the evacuation of Harvest is accomplished, saving 277,000 human colonists.
*Due to the loss of interstellar communications on February 21 and the relatively slow speed of the evacuation transports, the majority survival of the population of Harvest is not realized by the United Nations Space Command until December. 
*The senior Covenant officer of the Rapid Conversion, Maccabeus, is challenged and killed by his nephew Tartarus. While Tartarus assumes leadership of the immediate pack, the death of Maccabeus throws the Jiralhanae into political crisis; of all potential inheritors of his position as "Chieftain of the Jiralhanae," none are universally accepted as his successor.
24 February
Covenant space: Co-conspirators Ord Casto, Hod Rumnt, and Lod Mron are anointed as High Prophets, assuming the titles of Truth, Mercy, and Regret, respectively.

The Covenant battleship destroys frigates CMA Arabia and CMA Vostok, and badly damages the destroyer CMA Heracles. Both Arabia and Vostok are lost with all hands, while Heracles escapes into Slipspace. 1,700 CMA personnel are killed in the engagement. 
Covenant missionary ship Spirit of Fortune departs Harvest for High Charity with news of the encounter and evidence suggesting additional human worlds. 
25 October
Covenant space — High Charity: The Covenant missionary ship Spirit of Fortune arrives at the Covenant capital and delivers its report to the High Council. The revelation of possible additional Human worlds causes an immediate uproar; fully backed by the High Council, the Hierarchs order the Ministry of Tranquility to redeploy its missionary fleet to the suspected boundary of human space at once.

*The report on Bliss compiled by Y'gar 'Soramee, Ship Master of the Path of Serenity, incorrectly indicated human space forces as over twenty-five ships, resulting in a much larger deployment of Covenant warships to that world early in 2526. 'Soramee evidently mistook an outbound freighter group as a warship cluster. 
27 November
UEG space — Chi Ceti system: Covenant missionary ship engages the human frigate UNSC Commonwealth in the Chi Ceti system; after a brief engagement that severely damages both vessels, the Unrelenting withdraws away from the Commonwealth for minor repairs, fatally allowing the human warship to deliver the entire SPARTAN-II unit to Chi Ceti IV.

Despite heavier human space forces than anticipated, Joyous Unity still manages to deploy considerable ground forces to Alpha Corvi II.The rest of UNSC Battle Group Alpha arrives near Alpha Corvi II and engages Covenant forces; S-II commandos are deployed to the planet by the cruiser UNSC Persian Gate. Both UNSC and Covenant space forces suffer considerable losses while their ground forces clash on Alpha Corvi II.
— Alpha Corvi II: Covenant ground and atmospheric forces assail human settlements across the planet, especially Jamshid, the colony's largest city. The colony is defended primarily by the UNSC Marine Corps, but also by elements of the United Rebel Front (URF). In one of the first instances of its kind, URF forces fought alongside UNSC S-II Commandos against the Covenant in the vicinity of the settlement Black Reef. Despite the spirited defense of the planet, Vice Admiral Leland ordered UNSC forces to evacuate, and made no provisions for the evacuation of URF forces.
United Rebel Front troops continue to defend isolated settlements on Alpha Corvi II until being overrun on December 5.
— Alpha Corvi II orbit: UNSC forces complete their evacuation from the surface and begin to withdraw from the system. Given the disorder apparent in the enemy fleet, UNSC space forces continue to engage Covenant ships and transports. 
4 December

Alpha Aurigae system: Fourteen Covenant warships (three carriers, seven cruisers, and four destroyers) of the Fleet of Unceasing Prayer arrive in-system and begin moving towards the human colony world of Capella; they are intercepted by the seventeen human warships of the UNSC Battle Group Tango-3, which deploy against the Covenant fleet from the Origami Asteroid Field. Tango-3 successfully destroys the nearest covenant warship, a cruiser, before retreating into the asteroid belt; a single human corvette is lost in the attack. The Covenant, stung by the loss, break off from their approach and pursue Tango-3 into the Origami Asteroid Field.
The first Covenant warship to enter the asteroid belt, the light cruiser Valorous Blade, encounters a nuclear proximity mine and loses both shielding and navigation and is subsequently destroyed. Covenant forces continue their pursuit more carefully, successfully destroying a pair of human frigates and a human corvette. Tango-3's remaining thirteen warships continue to evade the Covenant. 
21 October

29 January
Ridgeway's Folly: Covenant fleet Strong Condemnation arrives 20 million kilometers from Ridgeway's Folly, and moves to engage. Following an in-system jump, 'Utaralee's flagship, the cruiser Faith and Fury, is attacked by Rear Admiral Gauthier's battle group; retaining two corvettes to use against Foxtrot-3, 'Utaralee orders the destroyer Unfettered Wrath and corvette Energetic Resolution to continue to and raze the human colony. Both warships are attacked by Battle Group Delta-5.
Foxtrot-3 suffers heavy casualties, both overwhelms and destroys the Covenant cruiser and both corvettes; Delta-5 is not so successful, despite destroying the corvette. Unfettered Wrath disengages from Delta-5 and moves to destroy the evacuation transports; in a last ditch effort, a frigate officer defies orders and rams the destroyer, bringing down its shields and allowing Delta-5 to destroy the Covenant vessel. 
*Strong Condemnation is destroyed; the Covenant suffer over 3,600 fatalities, while human military casualties are under 200. No human civilians are killed or injured.

Ariel: Covenant heavy cruiser Pious Fury arrives near and deploys ground forces to the human colony world of Ariel. Covenant ground forces quickly overwhelm the colonial militia and capture the majority of the planet's 4,000 colonists; despite the rapidity of their advance, however, the United Nations Space Command is alerted of the attack. The UNSC launches a small counter-attack to retake the colony, deploying two frigates and a detachment of the 105th Helljumpers to Ariel.
The Covenant begins excavating shortly after securing the colony.
8 January
Ariel: Covenant forces locate a Forerunner structure and begin exploring it; some human colonists are used to set off traps and defensive systems. Covenant ground forces move remaining human captives into the nearest human settlement, using them as makeshift prisons. Additional Covenant ground forces deploy to the more distant human settlement, garrisoning it against potential human reinforcements.
Two UNSC frigates arrive at Ariel, and deploy a combat team of Helljumpers; Covenant forces remain unaware of the arrival of the human forces until their perimeter garrison is engaged. The Helljumpers engage and destroy the Covenant perimeter garrison and move against the second settlement, ambushing and eliminating all Covenant reaction units encountered. UNSC forces subsequently overwhelm the diminished Covenant garrison near the dig site and rescue all surviving colonists.
Following the loss of immediate ground forces, the Covenant heavy cruiser Pious Fury deploys additional troops to Ariel, but recalls them following the destruction of the Forerunner artifact by marine personnel. All remaining Covenant forces evacuate Ariel and return to the Pious Fury, which quits the planet and withdraws. 
*Covenant losses during their invasion of Ariel are shockingly high: 1,037 dead, and a Phantom dropship destroyed. In stark contrast, Human fatalities number just 349.
