| '''Alpha Base''' was the main tactical [[Military base|firebase]] used during the [[Battle of Installation 04|Battle of Alpha Halo]] by surviving [[United Nations Space Command|UNSC]] forces after landfall on [[Installation 04]]. It was located on a small [[Wikipedia:Mesa|mesa]] several kilometers down-spin from the crash site of the {{UNSCShip|Pillar of Autumn}}. The mesa itself housed a collection of [[Forerunner]] structures as well as a system of caves stretching beneath the facility and linking with the larger subterranean system of the ring. | | {{Era|HCW|}} |

| | '''Alpha Base''' was the main tactical [[Firebase]] used by the remaining [[UNSC]] forces after planet fall on [[Installation 04]]. It was located on a small mesa several kilometers down-spin from the crash site of the {{UNSCShip|Pillar of Autumn}}. The mesa itself housed a collection of [[Forerunner]] structures as well as a system of caves stretching beneath the facility and linking with the larger subterranean system of the ring. [[Wellsley]] tagged the base as '''HS2604'''.<ref name="flood48">'''[[Halo: The Flood]]''' page 48</ref> |

| The [[human]]s set up camp around the base using the supplies they had scrounged from the ''Autumn'' and their [[Human Entry Vehicle]]s. They lived in [[prefabricated memory plastic cubicle|cubicles]] and ate mostly [[Meal, Ready-to-Eat]] ration packs. A good deal of activity also took place in caverns underneath the facility in the Forerunner structures. It was abandoned by the humans shortly before the destruction of the ring, due to their taking of the ''[[Truth and Reconciliation]]'' and the growing Flood presence in the area. | | The [[humans]] set up camp around the base using the supplies they had scrounged from the ''Autumn'' and their [[Human Entry Vehicles]].

| When the ''Pillar of Autumn'' was [[Battle Over Installation 04|attacked]] above the Halo by opposing Covenant forces, the [[Orbital Drop Shock Trooper|ODSTs]], under command of [[Major]] [[Antonio Silva]], abandoned the ship aboard Human Entry Vehicles. As the ODSTs fell through the ring's atmosphere, the [[Artificial Intelligence]] [[Wellsley]] tagged the Covenant base as '''HS2604''', suggesting that it would be ideal as a base for Silva's operations. Wellsley suggested the base be named 'Gawilghur', after a fortress that Arthur Wellesley, later Duke of Wellington, laid siege to in India. Major Silva shot down Wellsley's request and stated that most of the Marines would not be able to pronounce the name correctly.<ref name="flood2">''[[Halo: The Flood]], chapter two''</ref> | | When the ''Pillar of Autumn'' was attacked above the Halo by opposing Covenant forces, the [[Orbital Drop Shock Trooper|ODSTs]], under command of [[Major]] [[Antonio Silva]], abandoned the ship aboard Human Entry Vehicles, and most of them landed around the base. Silva saw the tactical advantage to the butte, and ordered [[First Lieutenant]] [[Melissa McKay]] to take it. <ref>''[[Halo: The Flood]]'', page 59</ref> While some of the ODSTs were able to attack the butte with supporting air support, some were lead into what was known as a back door. After elimination of all immediate threats, this team entered the back door and took a lift to regroup with the rest of the squad. It is unknown how much of a defense Silva put into guarding this pass, but apparently the Covenant were unable to use this backdoor to gain access to the base. |

|
| ===First attack on Alpha Base===
| | Despite now having this strategic foothold, Silva still had a great deal of problems. The ODSTs were equipped with enough food and supplies to last 2 weeks. However, that was not the case with the 63 crewmen that the Master Chief was able to rescue. Also, the dropships were running low on fuel and the base was not adequately prepared for a massive counter-attack. Therefore, Silva ordered McKay to go to the downed Autumn and recover whatever supplies that she could. The raid was a success and only a minimum of UNSC casualties occurred, while several [[Ghosts]] and a [[Spirit]] dropship were destroyed. The Marines and ODSTs were able to secure a sufficient amount of fuel, food, and munitions. Also, two 50mm turrets were recovered, a contingent of LRV Warthogs, and 4 Scorpion Tanks. Unfortunately, there was no ammo or rockets for the Pelicans, limiting their usage to transport only. Some of the supplies, LRVs, and Marines were lost in the return trip due to Covenant resistance. |

| |
| The majority of ODSTs landed around the base. Silva ordered [[First Lieutenant]] [[Melissa McKay]] to take the butte. McKay led an assault through a pass that was thought to lead to the top of the butte. As McKay and her company began their climb, the Covenant launched a preemptive strike against Silva. The attack consisted of an estimated one hundred [[Type-32 Rapid Assault Vehicle|Ghost]] rapid assault vehicles.{{Ref/Reuse|flood2}} | |
|
| |
|
| With half of his forces committed elsewhere, Silva ordered his A and D companies to form an "infantry square": an all-round defense formation that, coupled with the hilly natural terrain, gave the ODSTs a better chance of survival against the Ghosts' fixed weapons. To start, the Sangheili drivers fought very poorly. Several Ghosts fired upon each other or collided in their haste to score a kill. Eventually, a more experienced commander took charge and ordered the Ghosts to move around the square counter-clockwise and then to attack the lowest pit in the square. Human casualties increased and the square started to break. Silva responded by reinforcing the pit, ordering his [[M19 SSM Rocket Launcher|M19 missile]] operators to rotate their salvoes, and having his sniper team concentrate on the commander. As an apparent afterthought by the Covenant, Banshees attacked late and were quickly eliminated by M19 launchers. Finally, with the commander and 50% of their men dead, the attackers retreated, some carrying extra riders on their Ghosts. From that attack, the UNSC suffered 23 killed in action and 16 wounded in action, of which 6 were critical cases. Finally, Silva was able to order his [[D77-TC Pelican]] dropships to attack the butte and give Lieutenant McKay air support and distract the Covenant.{{Ref/Reuse|flood2}}
| | It was later discovered that the [[Flood]] had been attempting to break into the base and were only impeded by a single metal grate, (Which they had already used hundreds of Plasma Weapons on), leading to an unnoticed group of caverns. The entrances to these caverns were successfully sealed, and the Flood were delayed from overtaking the base. By the time they managed to break through, the [[UNSC]] forces had abandoned the base in hopes of leaving the installation aboard the ''[[Truth and Reconciliation]]''. |

| McKay, despite casualties, had made a good deal of progress moving up the butte. At last she made it to a "back door" into the butte. She fired an M19 missile into it, which struck an ammunition store and cleared the room of all hostiles. She and her company entered to find an elevator to the surface of the butte. As a result of the battle, the UNSC managed to gain a base of operations. It is unknown how much of a defense Silva put into guarding this back door, but apparently the Covenant were unable to use it to gain access to the base during later assaults.{{Ref/Reuse|flood2}}
| | The base was destroyed, along with Installation 04, when the Master Chief overloaded the ''Pillar of Autumn's'' reactor. |

| ===Guerrilla war=== | | ==Armament== |
| Despite now having this strategic foothold, Silva still had a great deal of problems. The ODSTs were equipped with enough food and supplies to last 2 weeks. However, that was not the case with the 63 crewmen that the [[SPARTAN-II Program|SPARTAN-II]] [[Master Chief Petty Officer]] [[John-117]] had been able to rescue. Also, the dropships were running low on fuel and the base was not adequately prepared for a Covenant counter-attack. Silva therefore ordered McKay to go to the downed ''Pillar of Autumn'' and [[Raid on the Pillar of Autumn|recover whatever supplies]] that she could find. The raid was a success with only a minimum of UNSC casualties, while several enemy Ghosts and a [[Dextro Xur-pattern Spirit|Spirit]] dropship were destroyed. The Marines and ODSTs were able to secure a sufficient amount of fuel, food and ammunition. Two 50mm autocannons were also recovered, a contingent of [[M12 Warthog Light Reconnaissance Vehicle]]s, and four [[M808B Main Battle Tank|M808B Scorpion]] tanks. Unfortunately, no ammunition could be found for the Pelicans, limiting their usage to transport only. Some of the supplies, LRVs, and Marines were lost in the return trip due to Covenant resistance.
| | The defenses of Alpha Base consisted mainly of UNSC personal that survived the crash of the {{UNSCShip|Pillar of Autumn}}. A number of stationary 50mm autocannons were in place and linked to the base's AI, Wellsley. The base had several makeshift landing pads where dropships could be docked and refueled in relative safety. Later, this position was reinforced by a group of LRV Warthogs and at least two of four Scorpion tanks that were recovered from the downed ''Pillar of Autumn''. |
|
| |
|
| ===Second attack on Alpha Base===
| | Due to successful raids and the attack upon the ''[[Truth and Reconciliation]]'', at least four [[Shades]], were set up in defense of the base. Unfortunately, these turrets had limited effectiveness against dropships. Also, 15 operational Covenant [[Banshees]] were recovered. A basic perimeter was set up and monitored through motion trackers by Wellsley. Pelicans had quick strike teams in place if their was a perimeter breach that could respond in about two minutes. Finally, a combination of LRVs and captured Ghosts were used as patrols, effectively combining power and speed. |

| |
| The second battle was [[Zuka 'Zamamee]]'s attempt to get into the base and kill the Master Chief. Approximately six [[Taaku Xur-pattern Spirit|Spirit dropships]] full of Covenant and the captured [[D77-TC Pelican|Pelican]] ''[[Charlie 217]]'' full of cloaked [[Sangheili]] commandos participated in the attack. The Pelican managed to touch down and release the Sangheili within before its landing pad was doused in fuel and lit. However, Zuka 'Zamamee and several Sangheili had already fled and began in search of the Chief. Before being killed by the [[Stealth Sangheili]] led by Zamamee, a valiant crewman, [[Cho (Navy technician)|Cho]], gave the AI Wellsley control of the 50mm autocannons, with which he was able to eliminate 1 Spirit dropship. The remaining dropships released their troops further away from the base and attempted to assault it thus. Snipers expertly inflicted heavy casualties on the disembarking troops. Two of the recovered [[M808B Main Battle Tank|Scorpion Tanks]] had been entrenched and were able to cut down much of the onslaught, including the [[Field Master|Field Commander]]. With their leader dead, lesser Sangheili attempted to assume command with little success. In addition, the Covenant were able to employ the {{Pattern|Kmiro'sish|Lich}} ''[[Upright Chalice]]'' in their attack, using it to deploy vast quantities of troops onto the base directly, before ODST [[Fireteam Raven]] were able to hold off the attack.<ref>''[[Halo: Fireteam Raven]], campaign level [[Alpha Base (Halo: Fireteam Raven level)|Alpha Base]]</ref> In the end, all remaining Covenant were either captured, killed, or forced to retreat. [[Yayap]] and [[Zuka 'Zamamee|Zamamee]] were able to survive by stealing one of the [[Type-26 Ground Support Aircraft|Banshees]] that the [[UNSC Marine Corps|Marines]] had been able to salvage.

| It was later discovered that the [[Flood]] had been attempting to break into the base and were only impeded by a single metal grate (which they had already used hundreds of plasma weapons on), leading to an unnoticed group of caverns. The entrances to these caverns were successfully sealed, and the Flood were delayed from overtaking the base. By the time they managed to break through, the [[United Nations Space Command|UNSC]] forces had abandoned the base in hopes of leaving the installation aboard the ''[[Truth and Reconciliation]]''.
| | At its strongest point, the bases defenses were as followed: |
| | *Battalion of ODSTs led by [[Major Silva]]. |
| | *Most of the Pillar of Autumn's remaining crew that were not captured or in cryo stasis. |
| | *Two 50mm autoturrets (AI operated). |
| | *High amounts of light and heavy weaponry (both UNSC and Covenant grade). |
| | *Four [[Shade]] turrets. |
| | *At least two of four remaining [[Scorpion Tanks]], dug partially underground for protection. |
| | *A contingent of LRV Warthogs. |
| | *15 operational captured [[Banshees]]. |
| | *Captured [[Ghosts]] (estimated at about 5-10). |
| | *[[AI]] [[Wellsley]]. |
| | *Multiple landing pads. |
| | *All surviving [[D77-TC Pelican Dropship|Pelicans]], but these were low on machine-gun ammo and had no rockets. |
| | *Ground based motion detectors. |
| | *A system of trenches surrounding the base. |
|

|
| The base was destroyed, along with Installation 04, when SPARTAN-117 overloaded the ''Pillar of Autumn's'' reactor. | | ==Battles== |
| | ===First Battle of Alpha Base=== |
| | The base was attacked twice while during the time the [[UNSC]] was on [[Installation 04]]. This attack was led by Major Silva and his battalion of ODSTs in an attempt to wrench the protective butte from the hands of the Covenant in order to establish a place where the UNSC personnel could regroup. Silva ordered Lt. McKay to lead an assault through a pass that hopefully led to the top of the base. As McKay and her company began their climb, the Covenant launched a preemptive strike against Silva. Wellsley informed him that the attack would consisted of an estimated 100 Ghosts. |

| ==Defenses==
| | With half of his forces committed elsewhere, Silva orders companies A and D to form into what is known as an infantry square. This, and the natural terrain, gave the ODSTs a better chance of survival against the Ghost's fixed weapons. In the beginning, the Covenant fought very poorly. Several Ghost fired upon each other or collided in their haste to score a kill. Eventually, a Field Commander took charge and ordered all of the riders to ride counter-clock wise and then to attack the lowest pit in the square. Human casualties increased and the square started to break. Silva responded by reinforcing the pit, getting his rocket-jockeys to rotate their salvo's, and had his sniper team concentrate on the Field Commander. As an apparent after thought, Banshees were thrown into the fight late and were quickly eliminated by M19 launchers. Finally, with the Field Commander dead, and a 50% casualty rate, the attackers retreated, some carrying extra riders on their Ghost. From that attack, 23 were KIA, 6 were critically injured, and 10 were WIA. Finally Silva could get the Pelicans to attack the butte and give McKay some support. |

Approximately 6 [[Spirit|Spirit dropships]] full of Covenant and the traitorous [[D77-TC Pelican Dropship|Pelican]] Charlie 217 full of cloaked commando [[Elite]]s participated in the attack.

However, Zuka 'Zamamee and several Elites had already fled and began in search of the Chief.

| ==Trivia== | | ==Trivia== |
| *The appearance of Alpha Base, as depicted in ''[[Halo: Fireteam Raven]]'', bears extremely heavy resemblance to the Forerunner structure found in the skybox of the ''[[Halo: Reach]]'' [[Anniversary Map Pack]] map [[Ridgeline]]. Notably, the doorway structures leading to the base's interior sections bear heavy resemblance to the map's red and blue bases and the overall structure exhibits extremely similar architecture. furthermore, Ridgeline's map description states that ''"This idyllic cliffside once served as a UNSC staging area''",<ref>''[[Halo: Reach]], [[Ridgeline]] map description''</ref> indicating that the staging area referred to in the map description is, in fact, Alpha Base (or a [[War Games]] map based on Alpha Base). | | *Wellsley suggested it be named 'Gawilghur',<ref name="flood48"/> referencing a fortress Sir Arthur Wellesley, Duke of Wellington, laid siege to in India. Major Silva shot down Wellsley's request and stated that most of the Marines wouldn't be able to pronounce the name right. |
| | *One of the said four [[Scorpion]] tanks is presumed to be the one encountered on Assault on the Control Room. |
