Vice Admiral Katrina "Kat" Cornwell was a Human female Starfleet flag officer who lived during the mid-23rd century. At one time she had been a therapist, and she had experience treating PTSD. (DIS: "The Red Angel", "Into the Forest I Go")
Ordering Lorca to Corvan IIEdit
In November of 2256, she informed Lorca – who had by then been replaced by an impostor from a parallel universe and made captain of the USS Discovery – about a concurrent Klingon attack on Corvan II and ordered him to protect that planetoid. (DIS: "The Butcher's Knife Cares Not for the Lamb's Cry")
In December of 2256, she attended a strategy briefing with Lorca, Terral, and three other admirals. She ordered Lorca to restrict the use of the spore drive since the Klingons might have learned of it and might target the Discovery. (DIS: "Choose Your Pain")
A week later, she visited the Discovery after Lorca launched an unauthorized rescue mission for Ambassador Sarek, whose ship had been disabled on the way to a diplomatic mission by an explosion that had deliberately been caused by an aide who had turned out to be a logic extremist. Cornwell and Lorca attempted to rekindle their romantic relationship. However, Cornwell made the decision to declare Lorca unfit for command after she tenderly awoke him the morning after, and he responded with a phaser in one hand and his other at her throat (due to lingering trauma relating to Lorca having recently served time in a Klingon prison; she was quite upset he kept a phaser under his pillow).
Capture on Cancri IVEdit
However, Sarek was too injured to attend his diplomatic mission to Cancri IV, a meeting with a supposed dissenting Klingon faction which could end the war, so Cornwell took Sarek's place, planning to recommend Lorca be stripped of command afterward. The mission turned out to be a trap orchestrated by Klingon General Kol, and Cornwell was captured by Dennas and Ujilli. (DIS: "Lethe")
Prisoner of WarEdit
Sometime later, Cornwell was kept prisoner by Kol aboard the Sarcophagus. Despite weeks of torture, she refused to give up any information. L'Rell offered her services to Kol as an interrogator in exchange for a cloaking device, but this was a ruse in order to get close to Cornwell. The imprisoned admiral met L'Rell when the latter arrived in her cell. At her insistence, Cornwell screamed, which she used to distract a guard away from the area. The admiral also learned that L'Rell wanted to defect to the Federation in exchange for helping her escape, the Klingon having grown disillusioned with how easy her people fell in line with Kol.
Attempted Escape with L'RellEdit
However, during the escape, L'Rell and Cornwell were confronted by Kol. Realizing they were unlikely to escape, Cornwell grabbed L'Rell's blade and attacked her, in order to maintain the illusion in front of Kol's men. Afterward, L'Rell hid the unconscious Cornwell in a side room – a room which, to L'Rell's horror, was filled with corpses. (DIS: "Si Vis Pacem, Para Bellum")
When Ash Tyler and Michael Burnham infiltrated the Sarcophagus to place sensors on the ship to allow Discovery to detect the Klingon ship while it was cloaked, the pair picked up Cornwell's life signs and found her in the side room where she had been placed earlier. Discovering L'Rell present in the same room, Tyler began experiencing intense flashbacks, and was unable to continue the mission. Burnham went on to complete the placement of the sensor on the bridge, while Cornwell tried to bring Tyler back to reality.
After Burnham successfully completed the placement of the sensors, Cornwell was beamed back to the Discovery along with Tyler, Burnham, and L'Rell. Cornwell was sent by emergency medical shuttle to Starbase 88 where she underwent surgery. She was expected to make a total recovery. (DIS: "Into the Forest I Go")
Following the Discovery's return from the mirror universe without Captain Lorca, Cornwell was visibly angered upon hearing of his betrayal, and upset at the presumed death of his prime universe counterpart. She assumed temporary command of the Discovery and took it to Starbase 1, only to discover that the starbase had been overrun and occupied by Klingon forces. When the mirror universe version of Philippa Georgiou proposed that the Federation strike the Klingon homeworld of Qo'noS directly, by detonating a bomb inside its mantle and rendering it uninhabitable, Cornwell supported the plan, even going so far as to help Georgiou masquerade as her deceased counterpart.
However, the Discovery's crew objected to the genocide they were about to be complicit in and threatened mutiny. When Specialist Burnham pointed out that Cornwell was making the same mistake she herself had made just before the Battle of the Binary Stars – forgoing Starfleet principles for the sake of survival – Cornwell abandoned the plan. Instead, she authorized Burnham to give L'Rell the bomb's detonator so that L'Rell could use it as leverage to take charge of the Klingon Empire and end hostilities. Cornwell later honored the crew of the Discovery for their actions during the war. (DIS: "The War Without, The War Within", "Will You Take My Hand?")
The Red BurstsEdit
Some weeks following the appearance of the Red bursts across the galaxy, Cornwell learned that USS Discovery and Section 31, in spite of having the same objective (to find Spock and to find out what links him to the Red Angel), were starting to walk on each other's toes at the expense of their mission. Cornwell arranged a meeting with Pike, Captain of the Discovery, and Leland, the Section 31 agent handling the Spock case, to force them to find common ground concerning the search for Spock. (DIS: "Saints of Imperfection")
She later arrived aboard Discovery via shuttlecraft to integorrate Spock herself. The questioning revealed that Spock was telling the truth when he denied being a murderer, or at least that he was convinced that he was telling the truth. She also revealed to Pike that Admiral Patar was a logic extremist. She remained on board the Discovery for a mission to Section 31 Headquarters. It was there that she learned that Patar, and most of Section 31's leadership, had been killed by Control. (DIS: "Project Daedalus")
Cornwell died in the line of duty in 2257, during a pitched battle against Control. After a torpedo, fired from Control's fleet, lodged itself in the hull of the USS Enterprise, Cornwell attempted to disable the torpedo. However, the attempt was unsuccessful, and Cornwell was forced to seal the blast doors from the inside. The torpedo detonated, killing Cornwell and causing considerable damage to the Enterprise, but Cornwell's sacrifice prevented the device from outright destroying the ship.

Memorable quotes Edit
"I can't leave Starfleet's most powerful weapon in the hands of a broken man."
"Don't take my ship away from me. She's all I got. Please, I'm begging you."
- - Katrina Cornwell and Gabriel Lorca, on Lorca's ability to command the USS Discovery (DIS: "Lethe")
"Bastard! The Lorca I came up with was measured, he was reasoned. I couldn't have imagined..."
"That Lorca was an impostor from an alternate universe was not the most obvious conclusion. We were all deceived."
"You sat out the war because if we'd lost to the Klingons, we wanted the best of Starfleet to survive. And as this conversation makes clear, that was you… and all you represent."
"You're welcome. Now, will you get off my ass so we can get back to work?"
"Admiral, we have a solution."
"I'm cringing already."
"And Chris? Whatever your path may be, you can handle it."

Background information Edit
Cornwell was portrayed by actress Jayne Brook.
The first name "Katrina" was initially only mentioned in the Netflix German voice dubbing list for "The Butcher's Knife Cares Not for the Lamb's Cry", but was first spoken in the following episode, "Choose Your Pain".
In Episode 4 of After Trek, shown after "Choose Your Pain", showrunners Gretchen Berg and Aaron Harberts mentioned that Cornwell is a psychiatrist by training, who is not only old friends with Lorca, but is assessing him as she supervises him, and is worried about him.
When asked how Cornwell would handle Saru's "break from reality" in "Si Vis Pacem, Para Bellum", Jayne Brook commented that the admiral would try to talk Saru down slowly rather than threaten to remove him from serving on his ship. Brook went on to say, "I think that she would give him time. I think she's a measured person who gives people the space, or wants to give them the space, to heal, and to observe herself. I think she would observe him and give him time." (After Trek: "Si Vis Pacem, Para Bellum")
