This should make things a little easier for anyone throwing theories into the forum. I have selected only the infromation following John's induction into the Spartan II program.

The information was collected from bungie.org


2517
Aug 17 Dr. Halsey and Lieutenant Keyes meet 6-year-old John on a playground in Elysium City, Eridanus-2.

2517
Sep 23 Project SPARTAN II begins on Reach with 75 conscripts. Project SPARTAN is an attempt to develop an effective, surgical military team to relieve political tensions and circumvent civil war.

2519
Jul 12 John makes squad leader.

2520
The Phoenix-class colony ship UNSC Spirit of Fire is refit as a military warship.

2523
Jul 14 SPARTAN Training exercise: Capture the Flag against Tango Company.

2524
Jun 16 As part of Operation: TREBUCHET, two four-man teams led by Staff Sergeants Nolan Byrne, and Avery J. Johnson (backed by the UNSC corvette Bum Rush hovering in high-orbit, and transported via two AV-14 Hornet fast attack aircrafts) infiltrate the city of Casbah on the outer colony of Tribute as ordered by Colonel Aboim. Their objective is to eliminate Insurrectionist bomb engineers. Although the UNSC Marine squads succeed in neutralizing an explosives-manufacturing facility, some of the Insurrectionists - armed mainly with handguns - smuggle the bombs into Casbah, the main population center of Tribute. The situation worsens, leading to a hostage crisis at one of the Jim Dandy restaurants where 38 civilians, 2 rebels and 3 of Sergeant Byrne\'s marines are killed, Byrne and Johnson themselves being wounded.

2525
Feb Minor Transgression, a Jackal-operated ship arrives in the Epsilon Indi System and discovers the human colony world of Harvest. The Luminary (a Covenant device designed to detect Forerunner artifacts) onboard the vessel pinpoints several thousands of Forerunner relics, including an Oracle, all registered on the surface of Harvest. The Jackals seize the opportunity to claim some of the relics for themselves before informing the Covenant High Council, and begin assaulting UNSC freighters (including the UNSC Horn of Plenty). The Office of Naval Intelligence responds to the mysterious attacks, misinterpreting them for Insurrectionist raids. Setting up a well-organized task force, Sergeants Avery Johnson and Nolan Byrne ambush the Jackals onboard one of the UNSC\'s freighters, foiling the aliens\' plans to land on Harvest, and delaying a potential invasion. Two survivors - the Grunt Deacon Dadab and the Engineer \"Lighter Than Some\" - flee the skirmish in an escape vessel. Following the engagement, the UNSC mobilizes the Colonial Militia (a reserve branch of the UNSC Army intended to defend a colony and protect its citizens in case of an enemy invasion) to confront a possible assault from this \"new enemy\".

2525
Feb 3 Contact with Harvest, an outer colony, is lost shortly after the colony itself had made contact with an unknown object. The Colonial Military Administration sends the scout ship Argo to investigate.

2525
Feb 11 Two members of the Covenant High Council - the Minister of Fortitude and the Vice Minister of Tranquility - conceive a plan to overthrow the Covenant Hierarchs in order to lay hold of the enormous amount of Forerunner relics. Political discords within the Covenant hierarchy determine the Ministers to utilize the Rapid Conversion - a Brute-controlled vessel guided by Chieftain Maccabeus and his crew - to lay siege on Harvest and gain control of the relics, without giving the Elites a chance to tip the power balance. Upon the ship\'s arrival in the Epsilon Indi System, the Brutes spot Deacon Dadab and Lighter Than Some\'s emergency escape vessel. Chieftain Maccabeus uses his finding as a profitable way to boost his Grunts\' morale, and repair the ship\'s damaged sections - which he intentionally wrecked - with help from Lighter Than Some.
The two AI\'s controlling the planet Harvest (Sif and Mack) design a peace message in the form of an image in an attempt to establish peaceful relations with the aliens. The peace offering fails after a disoriented Grunt fires on a colonial militiaman, leading to the Brutes\' onslaught upon the human colony.

2525
February - October After putting their coup to work, the Minister of Fortitude and the Vice Minister of Tranquility request the advice of an Oracle onboard the Forerunner Dreadnought. The Oracle reveals that Harvest does not hold Forerunner artifacts, but human settlements which the Covenant had mistakenly considered as being of Forerunner origin, claiming that the humans are actually \"Reclaimers\" or \"living Forerunners\". Having learned this, the two Ministers take their plan one step further, and uphold secrecy regarding the presence of living Forerunners on Harvest, as to avoid a major crisis which could ultimately lead to the downfall of the Covenant.

2525
Feb 23 As the Brutes begin to devastate Harvest, Colonial Militia forces evacuate civilians out of the major cities and ferry them to the capital city of Utgard. In an effort to save as many Harvesters as possible, the Colonial Militia transports the civilians to the orbital space station Tiara, which supports the seven space elevators of Harvest, and aboard the UNSC freighters. After several attempts to defeat Sergeant Avery Johnson\'s task force on the Tiara, the ten-Brute team led by Tartarus (a young Brute pack leader) is betrayed by Dadab and Lighter Than Some, hindering his chance to stop the Harvesters onboard the freighters to flee to safety.

Harvest is glassed, and the remaining survivors onboard the freighters are transported away from the devastation. Following the coup, the Minister of Fortitude and the Vice Minister of Tranquility become the High Prophets of Truth and Regret. Using the Luminary\'s guidance to discover human colonies, the Covenant declares war on humans in order to safeguard its place in the Forerunners\' history.

2525
Apr 20 The Argo arrives in-system and makes one confirmation transmission. No further reports are received.

2525
Mar 9 The SPARTANs undergo a radical series of biological, neurological, and physiological alterations. 30 die, 12 are permanently disabled, and 33 successfully adapt.

2525
Sep 12 The SPARTANs first \"official\" mission, to infiltrate the rebel base on Eridanus to capture the rebel leader, Colonel Robert Watts, is successful.

2525
Oct 7 A UNSC battle group, consisting of the destroyer Heracles, under Captain Veredi, and the two frigates Arabia and Vostok, enters the Harvest system and discovers that everything on the planet has been completely incinerated and the surface melted down to glass. In orbit around the remains of the colony world is a single alien ship, which proceeded to attack the battle group, destroying both Arabia and Vostok and badly damaging the Heracles. Intercepted communications identify the enemy as The Covenant. The message \"Your destruction is the will of the Gods... and we are their instrument\" is broadcast in UNSC language.

2525
Nov 1 Vice Admiral Preston Cole mobilizes the largest fleet in human history to retake Harvest.

2525
Nov 2 The SPARTANs learn of the attack of the Covenant at Harvest and Project MJOLNIR commences. CPO Mendez leaves to train next group of SPARTANs.

2525
Nov 27 Project MJOLNIR, a comprehensive package of scientifically enhanced armor, custom-tailored to the biologically augmented SPARTANs, is introduced to John and his squad at the UNSC Damascus Materials Testing Facility, on the planet Chi Ceti-4. The SPARTANs (now decked out in Mjolnir armor) destroy a Covenant ship by carrying a nuke onboard, inside the energy shield.

2530
The outer colony of Eridanus II is destroyed by the Covenant.

2531
Cole\'s war fleet engages the alien warship responsible for the decimation of the colony, scoring a victory (though the battle cost Cole two-thirds of his battle group). Only a last minute tactical inspiration turned the tide of battle.
After returning to Earth, Colepromoted to Admirallearns that a number of outlying colonies have been destroyed, leaving behind no survivors. Cole begins to move his fleet around, trying to intercept the invaders. Ground and ship-to-ship battles begin in earnest, raging throughout the Outer Colonies. During one ground engagement, Human forces capture one of the aliens. Before succumbing to his wounds, interrogators learn that the aliens refer to themselves as \"the Covenant\" (roughly translated).

2531
May 1 Spartan-II Blue Team is deployed on planet Victoria, located in the 111 Tauri System. Their mission is to infiltrate a United Rebel Front outpost and retrieve several stolen UNSC nuclear warheads. The operation is a success, leading to the death of General Howard Graves - one of the people speculated to be in charge of the United Rebel Front.

2531
Nov 7 SPARTAN-051, Kurt, is covertly reassigned to ONI Section Three and tasked with secretly training a new generation of soldiers, the SPARTAN IIIs, assisted by CPO Mendez and under the authority of Colonel Ackerson. He is promoted to Lieutenant and is given the last name Ambrose.

2535
In the course of four short years, Cole\'s forces are hammered, despite his excellent leadership and tactical brilliance. It is simply a matter of being outgunned; Covenant kill ratios tend to top four to one in ship-to-ship combat. By 2535, virtually all of the Outer Colony worlds have been destroyed by the Covenant. The \"Cole Protocol\" is established by military order: all human vessels must ensure that Covenant forces do not find Earth. Human ships must-when forced to withdraw-not move on to an Earth bound vector, even if that means jumping without proper navigational calculations. If blind jumps are not possible, the ship\'s captain must order self-destruction if capture is imminent. In addition, it is also imperative that the powerful ship A.I. data cores not fall into Covenant hands, so part of this protocol involves either the removal or destruction of the ship\'s A.I. in extreme situations.

2535
Feb 12 Jericho VII in the Lambda Serpentis system falls. Master Chief, on board the UNSC Destroyer Resolute under Captain de Blanc, is allowed to view as the Covenant fleet glasses the planet.

2536
Covenant forces begin to swarm into the Inner Colonies. For several years the war falls into a pattern: humans win isolated battles, typically during ground operations, but at a horrible cost. In space combat, the humans are losing at a precipitous rate, and one by one, the colonies fall.

2537
July 27 SPARTAN III Alpha Company begins Operation PROMETHEUS, to disable as much of the Covenant orbital shipyard K7-49 as possible. In a little over a week, the shipyard is completely shut down, at the loss of the entire company of SPARTANs.

2537
An armed insurrection takes place on the colony world of Mamore.

2539
SPARTAN III Beta Company Team X-ray vanishes while on a routine exercise north of Camp Currahee on the planet Onyx in the Zeta Doradus system. ONI fences off the area, designates it \"Zone 67,\" and declares it absolutely off-limits.

2545
July 3 SPARTAN III Beta Company is delivered to Pegasi Delta onboard the All Under Heaven, beginning Operation TORPEDO, the destruction of a Covenant refinery. The operation is a success, although all but two of Beta Company, Tom (B292) and Lucy (B091), are lost.

2547
Section Two of the Office of Naval Intelligence publicly announces the existence of the SPARTAN-II Program in an effort to boost morale throughout the UNSC.

2550
The Pillar of Autumn is refit to serve near Zeta Doradus.

2551
Feb 19 Biological augmentation of SPARTAN III Gamma Company, including significant brain chemistry modifications designed to enhance primitive survival responses in times of extreme stress, authorized by Lieutenant Ambrose.

2552
Jul 17 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 Cote D\'Azur. Keyes is promoted to Captain by Admiral Stanforth.

2552
Jul 18 The SPARTANs and the Marines engage Covenant forces on the ground, eventually nuking Cote D\'Azur and most of the Covenant invasion force (but very few humans), while 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 7 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.

2552
Aug 12 The Master Chief is debriefed by ONI at Camp Hathcock, Reach, on the events of Cote D\'Azur.

2552
Aug 25 The Pillar of Autumn is chosen by Dr. Halsey and Cortana (with Keyes as Captain) to handle a secret mission that Dr. Halsey is planning.

2552
Aug 27 John rejoins the remaining SPARTANS (except for three that are otherwise engaged - Gray team) in the FLEETCOM Military Complex on Reach, where they learn of their next mission: To acquire a Covenant vessel, navigate to the Covenant home world, and return with captured Covenant leadership.

2552
Aug 29 The Master Chief gets a neural interface upgrade and new armor with built-in Covenant shield technology. He is also introduced to Cortana, an A.I. created from Dr. Halsey\'s own neural patterns.

2552
Aug 30 Cortana gets revenge on Colonel 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.

2552
Aug 30 The remaining 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.

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.

2552
Sep 4 Lieutenant Wagner returns to Earth and reports on the evident destruction of Reach to Colonel Ackerson, Admiral Hood, and General Strauss at an ONI facility in Sydney, Australia.

2552
Sep 7 The Time/Date Record Anomaly of Sep 23, 2552 most likely rejoins the timeline here. Dr. Halsey and members of Red team discover an enigmatic shard in an ancient installation below the ONI facility. 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 artifact that the humans have found. Dr. Halsey destroys ONI\'s underground facility CASTLE BASE on Reach, preventing the Covenant from gaining control of its secrets.
Unknown 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.

2552
Sep 12 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 (the Beatrice), a Chiroptera-class vessel, the smallest UNSC classification that contains an SFTE. Before she goes, she gives the alien artifact to Corporal Locklear, with implicit instructions to destroy it.

2552
Sep 13 Admiral Whitcomb and Lieutenant Haverson destroy the majority of the surrounding Covenant fleet by detonating the Unyielding Hierophant. John, Linda, Will, and Fred, the last known remaining Spartans, along with Sgt. Johnson, and, of course, Cortana, depart for Earth to warn of the impending Covenant invasion.

2552
Sep 19 The Pillar Of Autumn arrives at Halo. A company of Orbital Drop Shock Troopers (UNSC Naval Special Forces) led by Major Antonio Silva and his second in command, Lieutenant Mellisa McKay land on Halo via \'Human Entry Vehicles\' and establish an operational firebase situated near a mesa a few kilometers away from the Pillar of Autmun\'s crash site. Alpha Base, as it was designated, had been supplied and heavily fortified with what remained of the Pillar of Autmun\'s arsenal.

Believing that the Master Chief was hiding out at Alpha Base, Covenant ground and aerial forces commanded by Zuka \'Zamamee and Noga \'Putumee attack the base in an effort to capture the Chief. The attack fails and the base is held by Major Silva.

2552
Sep 22 The Master Chief and Cortana, onboard a Longsword in the debris field of the destroyed Halo, find one remaining Pelican containing Sgt. Johnson, Lieutenant Haverson, Warrant Officer Polaski, Corporal Locklear, and a set of cryotubes containing Spartan 058, Linda.

Planning to fly the Truth and Reconciliation to Earth, Major Silva and the ODSTs abandon Alpha Base. The captured Covenant ship, however, had been sabotaged by Lieutenant McKay, leading to Major Silva\'s, the ODSTs and her death.

2552
Sep 23 The Master Chief, Cortana, Linda, Polaski, Sgt. Johnson, Haverson, and Locklear depart for Reach via Slipspace aboard the Covenant Flagship Ascendant Justice, captured near the Halo debris field. A Time/Date Record Anomaly continues from this point in the narrative, resolved above on Sep 7, 2552.

2552
October SPARTAN-062 (Maria) tests the Mjolnir MARK VI armor system against a platoon of ODSTs, guided by naval officers at the Songnam Special Warfare Center in Korea. The armor is approved and sent to the Cairo Orbital Defense Platform.

Blue Team responds to Covenant incursions and expeditions on Mount Erebus in the Antarctic and the Yucatan Peninsula. Covenant forces in the Antarctic are eliminated by a HAVOK tactical nuclear missile. These number of Covenant expeditions consisted in geological examinations and excavations of Earth\'s soil and seabeds.

2552
Oct 20 The Master Chief and Captain Keyes (post-humously) are decorated for their actions on Reach and Halo 04.

Concurrently, the Elite Commander of the Covenant fleet \"Particular Justice\" is punished for Heresy before being transformed into the Arbiter.

The Prophet of Regret and his relatively minor fleet arrive at Earth presumably looking for Forerunner installations, unaware of its status as the Human homeworld. After a brief conflict and some exploration in Africa, Regret retreats to Delta Halo 05 followed by Miranda and the In Amber Clad.

Four other UNSC vessels, the corvette Coral Sea, the two frigates Redoubtable and Paris, and the prowler Dusk are both close enough to the Slipspace rift and have charged Slipspace capacitors, and attempt to follow the In Amber Clad into the eleven nondimensions of Slipspace.

New Mombasa is destroyed in the Slipspace wake of Regret\'s ship.

2552
Oct 31 While engaged in a drill near Camp Currahee on the planet Onyx, members of SPARTAN III Gamma Company observe apparently newly-activated Sentinels operating within Zone 67.

2552
Fall UNSC ground forces (possibly UNSC Army) led by Colonel James Ackerson are pinned down against the Covenant Loyalist Army in the Mare Erythraeum basin on Mars. The battle results in a UNSC defeat, and Colonel Ackerson is captured and interrogated by the Brute Commander Lepidus onboard the Covenant cruiser Triumphant Declaration. While being tortured, Ackerson reveals that a certain \"Key of Osanalan\" located in the city of Cleveland, United Republic of North America on Earth, is required to properly fire the Halo arrays. This later sparks the Covenant Loyalist assault on Cleveland, where combined forces of UNSC Marines and ODSTs attempt to resist the onslaught.

From here on are the remaining events from Halo 2 and 3.
