Ages of Reclamation

The Ages of Reclamation are eras of the Covenant in which the true search for the Halo began. The Ninth Age of Reclamation is the time in which the first two Halo games are set. It is possible that each spanned three Human years. The first age began when the Minister of Fortitude ascended into the Prophet of Truth and declared war on the Human race.

The Ninth Age of Reclamation
The Ninth Age of Reclamation took place in the events of Halo: Combat Evolved, and Halo 2. This age possibly began in the year 2525, the year that the Covenant came into contact with humanity for the first time at the colony world of Harvest. The Covenant immediately attacked and decimated the world without warning. Spartan-II supersoldiers were deployed in the Battle of Chi Ceti, boarding a Covenant Frigate, planting explosives on the ship, and destroying it.

In 2530, the Covenant war machine attacked and glassed Eridanus II. The Battle of Harvest then took place in 2531, the first major space engagement between the UNSC and the Covenant. The Covenant were outnumbered, and the UNSC stood victorious, barely. In 2535, the Covenant destroyed Jericho VII in the Battle of Jericho VII, and by that year, the Covenant were driving and winning decisive victories against the UNSC, crushing the Outer Colonies. By 2536 Covenant militants swarmed into the Inner Colonies. For several years, human lives were spent in huge numbers winning ground operations, only to be wasted after the Covenant won the battle in space, glassing the Inner Colonies one after another.

Then, in 2537, Spartan-IIIs were trained and deployed in the battles of New Harmony, New Constantinople, and the Siege of the Atlas Moons. In Operation: PROMETHEUS, Spartan-III Alpha Company was slaughtered by Covenant forces. In 2544, the minor Battle of Miridem took place. In 2545, Operation: TORPEDO resulted in the massacre of Spartan-III Beta Company at Pegasi Delta. In 2552, the Battle of Sigma Octanus IV lead to a major UNSC victory, but at the cost of the Covenant learning the location of Reach and Installation 04. During the Battle of Reach, the largest naval battle between the UNSC and the Covenant, Covenant forces won a decisive victory, destroying 152 UNSC ships and 20 Super MAC gun platforms. This was a major blow to the UNSC, who lost their last great stronghold. A single UNSC ship, the UNSC Pillar of Autumn escaped to Installation 04. After four days of hard fighting in the Battle of Installation 04, the Covenant discovered the Flood organism and Forerunner constructs, which hampered their efforts to control the installation. The melee ended with the destruction of Installation 04, an event which left only a handful of survivors.

The Commander tasked with defending Installation 04 was put on trial, marked as a heretic to quell malcontent within the council. Later, he became the Arbiter, embarking on missions to quell a Heretic, and to retrieve the Index and the 343 Guilty Spark. Then, in Operation: FIRST STRIKE, Six SPARTAN-II supersoldiers were able to rout and destroy all but a dozen or so of a fleet of 500 Covenant starships in orbit around Unyielding Hierophant through the sacrifice of Admiral Whitcomb and Lieutenant Haverson on board Ascendant Justice. The survivors on board the UNSC Gettysburg surveyed the damage and jumped to Earth, scoring a major UNSC victory. The First Battle of Earth then occured. Though a relatively small and lopsided battle (15 Covenant ships fighting 75 UNSC vessels and 300 MAC platforms) this event is significant in that the Covenant discovered the location of Earth.

The UNSC won the fight with the help of the Master Chief. A single Covenant ship, belonging to the Prophet of Regret, survived the battle of Earth and retreated to Installation 05, known as Delta Halo. The Covenant ship was pursued by a single UNSC ship, UNSC In Amber Clad. This resulted in the Battle of Installation 05. Again, a massive fight ensues between the UNSC, Covenant, Flood, and Forerunner Constructs. The Flood appear to have been in control of part of the installation. The onslaught of the Covenant Civil War ended the 9th Age of Reclamation. This has been referred to as the ninth and final age.
