Wellsley

"Then God help you, because if your plan fails, no one else will have the power to do so."

- Wellsley to Major Silva, after Silva ignored Wellsely's advice regarding the Flood.

Wellsley was a 4th generation, Class-C Military dumb AI who helped Major Antonio Silva and First Lieutenant Melissa McKay set up and operate the Alpha Base on Installation 04. He was consumed in the destruction of the Truth and Reconciliation.

Fall of Reach
On August 30 2552, Silva reported to Wellsley that Spartans had taken all the M90 shotguns from the aft rack on the Pillar of Autumn.

Landing at Halo
As part of the UNSC Insertion Protocols, Wellsley was onboard Silva's drop pod. During the descent to Installation 04, Wellsley picked out a butte on the surface for Major Silva to act as an effective home base for the scattered UNSC forces on Halo. Wellsley then sent a message to the rest of the ODSTs about the location, and told Silva that the Covenant owned that location.

Later, he also warned Silva about a Covenant motorized counterattack, which he compared to the French cavalry charge at Waterloo, much to Silva's annoyance. To which Silva then used an Infantry square with A and D Company to counter the threat.

Wellsley then got in contact with Cortana, who was with John-117 rescuing crew members from Class-3 Bumblebees, and sent a D77-TC Pelican Echo 419 to pick them up. Wellsley also got in contact with Captain Jacob Keyes and the other surviving crew prior to their capture telling them his group and Cortanas were busy at the moment.

Wellsley then helped Pelicans such as Echo 136 get troops prepared for the assault on Alpha base, and after the assault was done helped get the rest of McKay's battalion to the the base.

Rescuing Keyes
After Alpha Base was secured, Wellsley, Cortana, and Silva concocted a mission to rescue Keyes, who was being held on the the Covenant ship Truth and Reconciliation. In preparation for this mission, Wellsley concocted an array of signals that was able to trick Covenant technicians into believing UNSC dropships were one of their own.

Covenant Alpha base attack
When Pelican Charlie 217 appeared, Wellsley recommended Com Tech First Class Mary Murphy to get more information out of the pilot, questioning how they even knew about Alpha Base, and put the base on full alert, also prepping a medical team. As Charlie 217 was landing, it turned out to be filled with Special Operations Sangheili, Wellsley noticed six heavy duty signatures, just as Alpha base was being overrun. To handle the upcoming forces, Wellsley recommended McKay and Silva handle the Covenant in the mesa while he dealt with the Covenant at the pads.

Murphy then took the safeties off the anti-air defenses and gave control to Wellsley, after which she and her two companions then were slaughtered by the Elites, Wellsley, witnessing the murders, killed the lights and notified Silva to then send a properly equipped team to deal with the Sangheili inside. At the same time, while control to the anti-air was too late to hit the first dropship, and was ineffective against the Type-26 Banshees, Wellsley managed to shoot down the second out of the six approaching Covenant dropships.

After the attack, Wellsley made a report on the event that concluded that the Covenant were searching for John-117. Wellsley also believed that the Covenant dismissed the Marines and Naval personnel as little more than a nuisance, and the enemy had since changed their minds, monitoring human radio traffic, conducting recon and so on.

The Flood
After the Flood attacked Alpha base forces, Wellsley believed that Halo was constructed to house them and keep them under control. Wellsley also had scans of the Flood corpses.

Wellsley and Cortana managed to link up again, and Cortana told him their plan to destroy the Autumn. Silva then planned to have Wellsley take a crack at flying the Truth and Reconciliation if Cortana couldn't make it to the ship.

Truth and Reconciliation assault
When the surviving Marines and ODSTs captured the Truth and Reconciliation, Wellsley sided with First Lieutenant McKay and attempted to convince Silva not to leave until they were sure that every last Flood on the ship was exterminated.

When McKay cut the communications to the engines, the Covenant ship lost control and crashed on Halo. He was fully aware of McKay's actions and just before the ship crashed, he told Silva that if he could be proud of one thing, it was that he had taught McKay well. Wellsley was presumed lost in the crash, as was almost the entire remaining UNSC presence on Halo.

Personality and traits
As with all AIs, Wellsley had the ability to choose his appearance. He chose to appear as a stern-looking man with long hair, a prominent nose, and a collared coat, and so resembled his namesake, Arthur Wellesley, the Duke of Wellington. Wellsley was created to act as a military assistant. He often referred to his victories as though he were the actual Duke and not an artificial re-creation, which annoyed many of his acquaintances.

It is possible, though unconfirmed, that he was the other A.I for the. Lieutenant Hikowa mentioned the AI as being for "point defense." It is also possible that "his" purpose as a second AI would be to guide Marine Forces whilst Cortana would guide the Spartans and fighter craft.

Storage
Wellsley was stored in an armored matrix that was often slung on Silva's shoulder.
