*1LT [[Melissa McKay]]

Following the arrival of the ''Pillar of Autumn'' in the [[Soell system]], Covenant forces of the [[Fleet of Particular Justice]] moved to engage the ship. Under orders from the [[Minor Prophet]] of [[Prophet of Stewardship|Stewardship]], the fleet was forbidden from firing their ship-borne weaponry for fear of damaging [[Installation 04]], and instead launched waves of boarding craft to try and flush the humans out. Nonetheless, [[Thel 'Vadam]]ee eventually ignored this request and began to fire on the human cruiser anyway. The battle in space would prompt Captain [[Jacob Keyes]] to initiate Article 2 of the [[Cole Protocol]], ordering a general evacuation of the ship. Most of the crew would evacuate by [[SKT-9 Bumblebee]] lifeboats, while the ship's ODST complement under Major [[Antonio Silva]] would deploy in their [[SOEIV]] drop pods.<ref name="flood1">''[[Halo: The Flood]]'', Chapter 1</ref>

The Orbital Drop Shock Trooper complement of the ''Pillar of Autumn'' would depart the vessel aboard their drop pods, equipped with two weeks of supplies each. Consistent with [[UNSC Insertion Protocols]], Major Silva's drop pod would enter the atmosphere of the ring first. Reasons for this were twofold; aside from the held belief that officers should lead, not follow, the practicalities of organising an invasion force meant needing to sort, organise and gather the available troops in the "golden hour" - the period of time in which the actions of the troops would most determine the success or failure of the mission. Silva's drop pod was appropriately configured with a Class-C AI - [[Wellsley]] - and high-powered imaging gear. Wellsley began to feed Silva reports of potential areas in which the ODSTs could hole up and defend, with one mesa dubbed ''"HS2604"'' serving nicely. The mesa was later named "[[Alpha Base (Installation 04)|Alpha Base]]", though first it had to be taken from the Covenant occupiers.<ref name="flood2"/>

The ODSTs landed in an area roughly three kilometres in diameter, with many of the pods smashing into cliffs, landing in lakes and one rolling into a ravine. However, the remainder were able to make their way towards Silva's position. Lieutenant [[Melissa McKay]] landed only half a kilometre away from Silva, and was briefed on the future-base by Silva. The base was heavily fortified, meaning that it would need to be taken by ground and air forces. Luckily, several Pelican pilots had managed to land their craft roughly ten kilometres to the north, and they would be used to launch air strikes and ferry troops from above while McKay's roughly 130-strong B company would assault from the ground. McKay's company spent the next night marching to the mesa, eventually ending up at the base. Thankfully, the Covenant had been unprepared for the arrival of a human cruiser and its troops, and all that blocked the troops was a hastily-constructed barricade.<ref name="flood2"/>

While B company prepared to assault the mesa, C company was designated to begin their march towards the Pelicans for aerial insertion and A and D company - under Silva - rested for the night in preparation for the day ahead. The companies camped out on a low rise without much cover, so instead tried to build up fortifications as much as they could while they slept. Wireless sensors monitored by Wellsley were placed two hundred meters around the camp and three-man [[fireteam]]s took up position one hundred and fifty meters out, with a rapid response team established to support them. Trenches and dirt barricades were dug out and a flat area for Pelicans to land was cleared. Around the time McKay's team began climbing the mesa, Wellsley reported that a Covenant response force was inbound to Silva's company, consisting of roughly one hundred [[Type-32 Ghost|Ghost]]s, for Silva's two hundred infantry. Silva ordered the troops to form an [[infantry square]], with ammunition moved down into the trenches alongside support weapons, with rocket launchers located halfway up the rise and [[sniper]]s on the top of the landing pad. With guns facing out every direction, the formation would be difficult to break. The ODSTs were surprised at being ordered to use such an archaic tactic, but complied nonetheless, and once ordered to fire, their armor-piercing rounds ripped through the light scout vehicles easily. The skittish nature of the vehicles caused many pilots to crash into each other, though eventually a [[Sangheili Zealot|gold-clad]] elite managed to organise the raiding force into circling the camp counter-clockwise to reduce collisions.<ref name="flood2"/>

The Ghosts began to focus their fire on one of the pits, beginning to kill the humans stationed there and slowly weakening one quarter of the camp defenses, prompting Silva to send a squad to reinforce and ordering his snipers to concentrate on eliminating the leader. The rocket-wielding heavy troops began to fire in volleys to make sure there wasn't a downtime between firing, and eventually the mangled wreckage began to provide cover for the humans. Banshees were sent in after the Ghosts, though the four were easily repelled by the [[M41 SPNKR|rocket launchers]]. After losing more than half their number, the Ghosts retreated, though the battle had resulted in twenty-three ODST casualties, six serious injuries and ten wounded personnel. By this time, McKay's company had engaged the enemy at the mesa, and Wellsley ordered the Pelicans to begin their attack.<ref name="flood2"/>

The Pelicans utilised their 70mm chin-mounted guns to cut down Covenant troops and [[Type-26 Shade|Shade turrets]] before dropping fifteen troops onto the mesa's landing areas each, with each dropship being ordered to return to their initial base and collect more troops for ferrying. Within minutes of the air attack, Covenant resistance in the base began to crumble. On her path up the mesa, McKay noticed a side door the Covenant had been defending, and ordered a rocket launcher be fired into the structure to clear out the inhabitants. By the time McKay's company made their way up the [[gravity lift]] to the surface, Silva and Wellsley were already on the landing pad and waiting - there had been several UNSC casualties but even more Covenant, and the rest of the battalion would be arriving within the hour.<ref name="flood3"/>

Many of the lifeboats deployed from the ''Autumn'' ended up scattered across the surface of the ringworld. Due to an airbrake failure, lifeboat [[Lima Foxtrot Alpha 43]] - carrying Spartan John-117 and AI [[Cortana]] - crashed on the edge of a cliff, killing all on-board personnel except for the aforementioned Spartan. The Spartan emerged from the pod and took cover in the nearby hills as Covenant Banshees and [[Type-25 Spirit|Spirit]] dropships began to converge on the crash site to hunt down any survivors. The Spartan engaged Covenant light infantry forces on the ground before eventually hearing the sound of UNSC weapons fire in the distance. Moving towards the sound, he found a Forerunner [[beam emitter|structure]] held by several marines and [[UNSC Navy|naval]] crewmen, besieged by Covenant troops.<ref name="flood2">''Halo: The Flood'', Chapter 2</ref><ref name="CEHalo">''[[Halo: Combat Evolved]]'', campaign level, [[Halo (Halo: Combat Evolved level)|Halo]]</ref>

As the Spartan neared the structure, he began to assist the troops by picking off the Covenant from afar, eventually coming into contact with Sergeant [[Avery Johnson]] and [[Fire Team Charlie]]. Johnson informed him of the situation; his marines were scattered all over the valley from the evacuation, and being picked off by the Covenant. Luckily, Cortana had been in contact with [[Wellsley]] - the ODST battalion assigned to the ''Pillar of Autumn'' were in the middle of taking a base for reorganisation, and a Pelican dropship had been assigned to help pick up the survivors. At this moment, Private [[Bisenti]] noticed a Covenant [[Type-25 Spirit|Spirit]] dropship coming in to deposit more troops, prompting the squad to reform and begin their defense again. After several waves of infantry, Pelican ''[[Echo 419]]'' radioed in to try and find survivors in the area, allowing [[Carol Rawley|Foehammer]] to bring in a [[M12 Warthog|Warthog]] as more lifeboats began to pass overhead. ''419'' deposited the Warthog for the Spartan to use, with PFC [[M. Fitzgerald]] joining as the designated [[M41 Vulcan]] gunner.<ref name="flood2"/><ref name="CEHalo"/>

The Warthog proceeded inside a large cave, of artificial construction. The Spartan reasoned that the tunnel would likely have to lead somewhere, and proceeded inside. After several twists and turns, the vehicle arrived in a large cavernous space where the road stopped. The Covenant began to pour out of the structure, with Fitzgerald using the rotary cannon to fire upon the encroaching infantry while John moved left to flank. The Marine was hit in the arm with a [[Type-33 needler|needler]] shard, rendering him ubale to fire, though the biofoam administered later would leave his recovery hopeful. However, the gap still presented an issue, though Cortana suggested that the artificial construction meant some kind of bridge mechanism was likely available to allow progress. A small alcove in the side of the room proved to lead into a short corridor containing a [[Sangheili Major]], who was dispatched in short order. At the end of the balcony overlooking the space was a console, flashing with [[Geas|familiar symbols]], despite the fact John had never seen them before. Activating the console activated a [[light bridge]], allowing the Warthog to proceed across the gap.<ref name="flood2"/><ref name="CEHalo"/>

Emerging out of the cave structures, the Warthog proceeded up a rise to look out over the valley. Noticing a passage on the right, the Warthog was steered into the smaller passage to arrive into a small canyon with a [[beam emitter]] at the centre, and a group of UNSC personnel hiding on a hill on the far side. Before long, ''Echo 419'' arrived to pick up the survivors, and the Spartan mved on. The process of checking all the interlocking valleys and canyons for survivors took the remainder of the afternoon, resulting in 63 naval and marine personnel rescued, before John finally boarded the Pelican himself to return to Alpha Base.<ref name="flood2"/><ref name="CEHalo"/>

Several groups of UNSC personnel landed on the surface of Installation 04 that went unaccounted for later in the battle. [[Fireteam Raven]], an ODST fireteam, landed on the ring in time to view the ''Pillar of Autumn'' crash.<ref>''[[Halo: Fireteam Raven]]'', campaign level [[Escape (Halo: Fireteam Raven level)|Escape]]</ref> Guided by Wellsley via mobile uplink, Raven would eventually meet up with Lieutenant McKay and her company during the midst of the later [[Raid on the Pillar of Autumn]], twenty-eight hours later.<ref name="CFRaven">[https://www.halowaypoint.com/en-us/news/thats-so-raven ''Halo Waypoint:'' Canon Fodder - That's So Raven]</ref> Another group of survivors would land near a [[Ridgeline|large Forerunner complex]] similar in appearance to Alpha Base, though deep in the forest. These survivors would make a staging area, though a Covenant assault later in the conflict would wipe out the encampment.<ref>''[[Halo: Reach]]'', [[Ridgeline]] map description</ref><ref name="nelson">[http://majornelson.com/2011/08/26/news-from-halo-fest/ ''Xbox Live's Major Nelson: News From Halo Fest''] ([https://web.archive.org/web/20110909143312/https://majornelson.com/2011/08/26/news-from-halo-fest/ Archive])</ref>

Another group of ODSTs would land near a similar cliffside beam emitter as the one encountered by the Master Chief, and hold off Covenant attacks there.<ref name="nelson"/><ref>''Halo: Reach'', [[Firefight]] level [[Installation 04 (level)|Installation 04]]</ref>

Pelican pilot [[Rick Hale]] would suffer several issues with his dropship upon leaving the ''Pillar of Autumn'', and would eventually put down in the remote regions of the ring to work on repairs. He would later be captured by the Covenant, and eventually forced at gunpoint to fly a Pelican loaded with [[Special Operations Sangheili]] onto the landing pads of Alpha Base, kickstarting the [[Battle of Alpha Base]] two days later.<ref>''Halo: The Flood'', Chapter 8</ref> An [[Unidentified private]] of the [[79th Infantry Battalion]] would later send a report through the transmitter of lifepod [[Lima Foxtrot Alpha 19]] reporting that his unit had been devoured by the [[Flood]] following the parasite's [[Outbreak at the Containment Facility|outbreak]] later in the conflict. It is unknown if this marine, and his unit, were able to link up with the UNSC forces of Alpha Base.<ref>''Halo: the Flood'' (2010), Adjunct - [[Entry 47-2396/10763]]</ref> Several other personnel including [[Elias Haverson]],<ref>''[[Halo: First Strike]]''</ref> [[Marvin Mobuto]]<ref>''Halo: The Flood'', Chapter 9</ref> and [[Thomas Chang]]<ref>''[[Halo 3]]'', [[Believe]] diorama</ref> would land on the installation, and have thus far gone unconfirmed as to whether they were able to link up with the forces of Alpha Base.

During the space battle, Sangheili [[Isna 'Nosolee]] was deployed onto the ''Pillar of Autumn'' as an [[Ossoona]], or "Eye of the Prophets". The Sangheili was tasked with three objectives; capturing the ship's AI, command crew and recording anything he saw. Deeming the AI to be destroyed or removed from the ship, the elite began to find his way to the ship's bridge. Once the bridge crew found their way to their designated escape pod, the elite boarded, but the shimmer of his [[active camoflage]] gave him away and he was shot by Captain Keyes.<ref name="flood1"/> The rest of the ride down to Halo's surface was uneventful, thanks to the flight skills of the pilot [[William Lovell]]. Once landed, the crew began to strip the lifeboat and dump the elite's body in a crevice, though it wasn't long until a sonic boom signalled the arrival of the ''Pillar of Autumn'' in the ringworld's atmosphere. The bridge crew began to climb up a nearby hill, intending to hide out in a cave until such a time as support could rescue them.<ref name="flood2"/>

However, it wasn't long until the Covenant got wind of the landing site of the bridge crew. The lifeboat was quickly found, and 'Nosolee's body not lang after. From there, Covenant command was notified and it didn't take long for it to be determined that 'Nosolee wouldn't risk his life unless there was something of importance within the shuttle. From there, the Covenant began to search the region for the human commander, but there was only one problem; the hillside terrain made landing troops difficult, and it was still important to ascertain which human 'Nosolee had been seeking. Because of this, the Covenant began to deploy Banshee air recon, but were still at a disadvantage due to their strict orders to take the humans alive. Nonetheless, the tightening Covenant net proved difficult for the humans, who were constantly harassed at every turn, with Corporal [[Wilkins]]' marines managing to barely hold off the aliens. As the day went on, Ensign [[Ellen Dowski]] began to crack, beginning to complain and eventually beginning to suggest turning themselves over to the Covenant - reasoning that they could have been killed by plasmafire or bombs at any point, yet they were alive. Unable to charge the junior officer with insubordination, Keyes instead allowed Dowski to surrender, though ordered her stripped of weapon, supplies and tied up to make sure she couldn't follow the rest of the group.<ref name="flood3">''Halo: The Flood'', Chapter 3</ref>

Eventually, a Covenant dropship landed several Sangheili troops a kilometre to the south, prompting the party to once again set off. As they set off, the Sangheili [[Ado 'Mortumee]] noticed on his heat signature tracking that one of the dots on his screen was staying behind. Dowski was eventually picked up by the Covenant - alive, and assisted the Covenant in locating the rest of the command crew. For the next three hours, the party would continue to evade the Covenant, but eventually made their way into a box canyon with no retreat. As a Spirit began to descend into the canyon, Dowski's voice on the speakers informed the command team of this fact, and that there was nowhere to go. Eventually, Dowski jumped out of the dropship followed by a team of Sangheili, whereupon she identified Keyes as the leader of the group. The elites proceeded to execute the remaining crew, much to Dowski's horror, before executing her with her own pistol. They lifted Captain Keyes into the dropship and took him away to the brigs of the ''[[Truth and Reconciliation]]''.<ref name="flood3"/>
