===Isolated battles (2525)===

{{Main|First Battle of Harvest}}

Humanity and the Covenant first came into direct contact on February 3, 2525, when a [[Kig-Yar]] [[missionary ship]], the ''[[Minor Transgression]]'', discovered [[Horn of Plenty|a human ship]] transitioning out of [[Slipstream space|slipspace]] and subsequently raided the vessel.<ref>''Halo: Contact Harvest'', p. 27</ref> The raid continued to [[This End Up|another]] unfortunate human ship.<ref>''Halo: Contact Harvest'', p. 97-100</ref> Some time after, [[Sif]], Harvest shipping operations AI, investigated the raids and reported her findings to an undercover [[Office of Naval Intelligence]] agent, [[Jilan al-Cygni]], believing that the attacks were Insurrectionist activity. The ONI agent devised a trap for the raiding parties, which resulted in a [[Skirmish Over Harvest|minor skirmish]] between [[Staff Sergeant]]s [[Nolan Byrne]] and [[Avery Johnson]], and the Kig-Yar privateers.<ref>''Halo: Contact Harvest'', p. 128-134</ref> When the Covenant returned with [[Rapid Conversion|another ship]] and a contingent of [[Jiralhanae]] and [[Yanme'e]], the UNSC proposed a meeting (via pictogram) with the intention to make amends and to trade with the alien species.<ref>''Halo: Contact Harvest'', p. 229</ref> The Covenant met the UNSC on Harvest, but were only interested in claiming the relics that the [[Luminary]] had detected on Harvest, completely oblivious that the humans were the "relics" in question. The meeting was botched after [[Osmo]], a member of the [[Harvest militia|Colonial Militia]], was attacked by a nervous [[Unggoy]] who was part of a second Covenant force sent to look for the relics. As a result, a firefight erupted between the two groups and the Covenant promptly retreated back to their ship.<ref>''Halo: Contact Harvest'', p. 213</ref>

The political ramifications of these relics were abundant, and two [[San'Shyuum]] bureaucrats, the [[Prophet of Truth|Minister of Fortitude]] and the [[Prophet of Regret|Vice Minister of Tranquility]], were already scheming to use the supposed reliquary to inaugurate a new [[Ages of Reclamation|Age of Reclamation]] with themselves as the [[Hierarchs]] of the [[High Council]].<ref>''Halo: Contact Harvest'', p. 271</ref> To do this, they needed the blessing of the Oracle of [[High Charity]]. When the two San'Shyuum approached the [[Prophet of Mercy|Philologist]] to affirm on their behalf, the data from the ''Rapid Conversion'' caused [[Mendicant Bias|the long-dormant Oracle]] to reactivate. Mendicant declared that the Covenant had been misinterpreting Forerunner symbols: the "relics" in question were the humans, calling them [[Reclaimer]]s and his makers. This shocked the three San'Shyuum, who falsely concluded that the humans were actually living [[Forerunner]]s who had been left behind when the others transcended.<ref>''Halo: Contact Harvest'', p. 275 ("'The Forerunners,' the Minister whispered. 'Some were left behind.'")</ref> Although they were able to prevent Mendicant from taking the [[Forerunner Dreadnought]] to take the humans to deliver them to [[Installation 00|the Ark]], Fortitude concluded that if the masses learned that they might be left behind, they would rebel against the Prophets. Fortitude and Tranquility inducted the Philologist into their plan and ascended as the High Prophets of Truth, Regret, and Mercy.  

===Open war (2525-2535)===

{{Main|Massacre of the Outer Colonies}}

From that point on, the Covenant continued to attack and destroy the humans wherever they were found, using their [[Luminary|Luminaries]] to find human worlds. Though the UNSC forces fought bravely, their inferior technology and numbers meant that even a ''close'' victory was far from guaranteed. The Covenant, fighting a war of extermination, did not need to commit to full ground invasions except in special circumstances; their ships simply needed to destroy space-borne defenses and any other threats around the planet. They would then reduce the planet's surface to glass with orbital plasma bombardment.<ref>''[[Halo Encyclopedia (2009 edition)]]'', Chapter 1, p. 33</ref> In general, human missiles and magnetic acceleration weapons were asymmetrically matched with Covenant energy shields and plasma weaponry. The few major victories achieved by the UNSC were usually due to tactical genius, extensive use of nuclear weapons, the rapid deployment of Spartan teams, or decisive ground engagements where UNSC technology and skill outmatched Covenant tactics. At the outset of the war, the UNSC employed a [[Wikipedia:defence in depth|defence in depth]] tactical doctrine, making extensive use of [[M5 Talos|automated turrets]] to delay Covenant forces.<ref name="PL Turret">''Halo Wars 2'', [[Phoenix Logs]] - Turret</ref> They were eventually forced to abandon this doctrine as the war continued to grind down human armies and industrial centres{{Ref/Reuse|PL Turret}}, learning the dangers of relying on fixed installations when employed against enemies with orbital fire support.<ref name="PL Siege">''Halo Wars 2'', [[Phoenix Logs]] - Siege Turret</ref> The UNSC began to develop a modular [[firebase]] system (based on pre-existing [[colony starter unit]]s used for colonization of planets<ref>[http://www.halowars.com/GameInfo/UNSC.aspx ''Official Halo Wars Community Site'': UNSC] (defunct, [[Archive:Halowars.com/UNSC|Archived]])</ref>) in response to pinpoint Covenant targeting of large military command and control installations with orbital strikes, and the inability of standard counter battery systems to detect, deflect, or defeat plasma-based artillery bombardment.<ref name="PL Siege"/>

=====The Apex and the Arbiter (2531)=====

Despite the well-publicized victory at Harvest, the UNSC was already on the way to losing the war. A number of colonies had already been glassed by the Covenant or abandoned, including [[Eridanus II]], [[Dwarka]], [[Bliss]], [[Madrigal]], [[Asmara]] and [[Biko]]. The UNSC's sole hope apparently lay with the SPARTAN-II Program. However, there were never enough Spartans to decisively turn the tide of the war in favor of humanity. Recognizing this, the [[Office of Naval Intelligence]] authorized the creation of the [[SPARTAN-III Program]]. The brainchild of [[Colonel]] [[James Ackerson]], these Spartans would be trained with a greater emphasis on stealth and teamwork, and would be sent on missions against high-priority targets that would be impossible even for elite units.<ref>''Halo: Ghosts of Onyx'', p. 43-46</ref>

With the majority of the Outer Colonies glassed or abandoned, the UNSC faced an economic crisis, as many of their [[agriculture world]]s had been destroyed, leading to food shortages. On [[Charybdis IX]], food riots were common.<ref>''Halo: The Cole Protocol'', p. 106</ref> Meanwhile, Covenant forces began to encroach on the [[Inner Colonies]].<ref>''Halo: The Cole Protocol'', p. 25</ref> In response, the UNSC issued [[United Nations Space Command Emergency Priority Order 098831A-1]], otherwise known as the "Cole Protocol". It stated that no UNSC vessel may lead the Covenant to Earth or any other human population center. Furthermore, all movement through space was restricted to [[UNSC Navy]] vessels.{{Ref/Reuse|Genesis}} [[Insurrectionist]] attacks increased in the face of what the colonies perceived as a removal of their right to freedom of movement. This was to culminate in the discovery of Insurrectionists using Covenant weapons supplied by apparently renegade [[Kig-Yar]]. Shocked, the UNSC viewed this as a major threat to security.<ref>''Halo: The Cole Protocol'', p, 109</ref> Upon learning of this, the [[Prophet of Regret]] declared such weapons as heresy, and as a result dispatched [[Thel 'Vadam]]ee to destroy the source of the modified weapons: a remote asteroid habitat known as [[the Rubble]].<ref>''Halo: The Cole Protocol'', p. 146</ref>
