Spencer Estate investigation (2006)

"A few years ago, the BSAA received intel to the whereabouts of Umbrella's founder, Oswell E. Spencer. Jill and I were ordered by the BSAA's European Headquarters to apprehend him. We accepted that mission in hopes of uncovering some info that would lead us to Wesker."

In 2006, Redfield and Valentine received a tip-off from a reliable source detailing the location of former Umbrella founder Oswell E. Spencer, and the pair intended to raid his hideout and arrest him for questioning.

Entering the estate, it was not long before they discovered the bodies of Spencer's bodyguards who were already brutally killed through "unconventional means". They survived and endured numerous puzzles and traps built on the estate while fending off multiple Guardians of Insanity, which relentlessly pursued them throughout their mission. Proceeding through the estate's gardens, they fell through an old bridge and landed in the sewers below, losing most of their equipment in the process. Defenseless, the agents outsmarted and eliminated the remaining Guardians of Insanity before escaping from the sewers. When they arrived at the last hallway in the estate, they discovered more of his bodyguards horrifically murdered outside the entrance. When they opened the last door where Spencer could be hiding, they are greeted by Wesker who had just killed Spencer moments before. A brief battle soon followed. Despite their best efforts, both Redfield and Valentine are easily beaten by Wesker's superhuman powers. Just as Wesker was about to deal the killing blow to Redfield, Valentine tackled Wesker out of a nearby window and both fell into a chasm. Redfield could do nothing as he watched his partner fall to her death.

The BSAA conducted a three-month search for Valentine's body, but with no success. As a result, Valentine was officially declared killed in action. For the next three years, Redfield refused to believe that Valentine died and put himself into every mission available with the hopes of finding some kind of lead to her whereabouts. Redfield eventually got wind of some rumors that Valentine was still alive, although he was unable to confirm them until 2009.


Kijuju Incident (2009)

"More and more I find myself wondering if't is all worth fighting for. For a future without fear? Yeah, it's worth it."

In 2009, Chris Redfield was arguably the most active and respected member of the BSAA, participating in more missions than anyone else, and was largely responsible for their success. In March, during one of his investigations, Redfield uncovered an upcoming bioweapons deal to occur in the Kijuju Autonomous Zone of Africa. Redfield was sent to Kijuju alongside his new partner, Sheva Alomar, as well as BSAA Alpha Team, to arrest bioweapons dealer Ricardo Irving, who had connections to the rumored Uroboros virus.

After Redfield and Alomar met their contact, Reynard Fisher, who provided them with equipment and the mission details, they proceeded to their rendezvous with Alpha Team at the deal coordinates, encountering and fighting locals infected with Las Plagas who became Majini. The mission went awry when Redfield and Alomar witness Reynard's execution by an angry mob, as well as discovering that Alpha Team had been almost completely massacred - apart from Captain DeChant, who was mortally wounded. Before dying, DeChant revealed that the deal was a set-up and handed Redfield a hard drive containing data he retrieved from Irving.

The pair received orders to relay the data through a computer at the nearby storage facility. En route, they encountered a new type of B.O.W. infected with Uroboros, the same one that killed Alpha Team, and managed to defeat it. Arriving at the computer, Redfield uploaded the data to HQ, who reiterated that capturing Irving was their top priority and instructed the duo to head to the mines past the train station, despite Redfield's apprehension.

On the way to their next objective, Redfield witnessed his air support helicopter, piloted by Kirk Mathison, attacked by Kipepeo and crash land further into the town, and switched his priority to attempting to rescue him. Arriving at the crash site, he found Kirk's body charred atop a pile of burning tires, leaving Alomar and himself vulnerable to an ambush from a Majini motorcycle gang. They are saved by Delta Team, led by Captain Josh Stone, who passed on the analysis of HQ's data to Redfield and confirmed that Irving has moved into the mines. When Redfield looked at the data, he found a picture of a woman bearing a strong resemblance to Jill Valentine, causing him to have brief flashbacks of the Spencer Estate Investigation, but ultimately he shrugged them off and continued the mission.

Making their way through the train station and mines, Redfield and Alomar managed to corner Irving in a building by the mine's cliffside, but a diversion allowed a mysterious cloaked woman to save Irving from capture. Having lost the target, Redfield checked the files that Irving left behind, which hinted at an oil refinery in the marshlands as being Irving's next destination, but decided to rendezvous with Delta Team first, with BSAA trooper Dave Johnson transporting Alomar and himself to the meeting point. When he arrived at the rendezvous, it appeared that Delta Team had also been mysteriously wiped out. However, upon further investigation, he soon met the culprit of the massacre, Ndesu, who crushes Dave underfoot. Redfield and Alomar managed put down the monster with mounted machine guns. Upon Alomar's discouragement at the demise of her comrades and her suggestion to back out, Redfield revealed his personal stake in the mission - he'd received intel that Jill Valentine was still alive, and the data they recovered from HQ confirmed his suspicions. He also opened up to Alomar about the Spencer Estate Investigation.

Redfield and Alomar made their way through the land of the Ndipaya tribe, oddly coming across tents bearing the logo of TRICELL, a prominent pharmaceutical company. Upon arriving at the refinery, they ran into Stone, who survived the Ndesu massacre. He stated that Irving would blow up the facility in his escape, and suggested they try to catch Irving at the docks; they failed in their attempt, and only just managed to escape on their own boat before the refinery exploded. Fighting through the oil fields, Redfield caught up with Irving's boat and boarded it, confronting the arms dealer, who out of desperation injected himself with the Dominant Species Plaga and mutated into a giant sea monster. Redfield and Alomar managed to defeat Irving, separating him from his massive husk and flinging him back onto the boat. Before Irving perished, Redfield interrogated him about Valentine and Uroboros, leading Irving to direct them to a nearby cave.

Upon arriving at the cave, Stone bid farewell to Redfield and Alomar and offered to try sending backup. They proceeded through a large underground ruin and eventually came across an old Umbrella laboratory, where the Progenitor Virus originated from, and more links to TRICELL. Redfield eventually discovered a large containment room full of capsules used to store test subjects, where he used the control system to search for Valentine. But as the platform descended, he and Alomar were attacked by a large creature known as U-8, promptly stopping the platform and forcing them to wrestle back control. In the end, Redfield found the capsule empty. Excella Gionne, the co-founder of TRICELL, finally appeared to Redfield, gloating and refusing to reveal Valentine's whereabouts. As he proceeded further into the lab, Redfield overheard a conversation on his comms between Gionne and Albert Wesker, alerting him that Wesker also survived the Spencer Estate incident.
