Diary 23
That man has never seen the savage face of war. But he will.
― Cornelius Slate, referring to Comstock.[src]

Captain Cornelius Slate is a citizen and soldier of Columbia, whose view on the military is based on both elaborate expectations and his real experiences. Once a proud supporter of Zachary Hale Comstock, Slate became disillusioned due to what he perceived as Comstock's falsified military record and stolen valor, and he was expelled from the Columbian military for making his allegations public. During the events of BioShock Infinite, Slate leads a rabble of "true" soldiers, who have forcefully occupied the Hall of Heroes in Soldier's Field.


A career soldier, Cornelius Slate began his military service in approximately 1872.[1] He served in the 7th Regiment, United States Cavalry and participated in the Battle of Wounded Knee, where he became acquainted with Booker DeWitt (whom he refers to as "Corporal DeWitt"). Some time later, Slate became a follower of Zachary Comstock and a citizen of Columbia. In 1898, during the Spanish-American War, he was among the commanding officers in the Battle of San Juan Hill.[2] Three years later, Slate participated in the Boxer Rebellion in Beijing on behalf of Columbia, where he lost his left eye and 30 comrades who fought under his command. He elected to cover his lost eye with a Pinkerton Badge.

While Slate earned the respect of many of Columbia's armed forces, he later found life in the floating city to be anything but heavenly. He became disenchanted with Comstock after seeing the whitewashed, sanitized display in the Hall of Heroes. However, Slate was most angered by the Prophet's false war record — Comstock claimed to have been present at the Battle of Wounded Knee, and the hero of the Boxer Rebellion, both claims Slate adamantly denied, never having known Comstock to be present with his cavalry command at Wounded Knee. When Slate confronted Comstock with his accusations, he was stripped of his rank, publicly branded a liar, and sent to work in Finkton.[3][4]

Filled with rage over Comstock's apparent treachery, Slate escaped and made a truce with the Vox Populi.[5] He led a small team of personally loyal soldiers to take over the Hall of Heroes, killing everyone in their path (including Leander Manley), defacing the building and monuments within, and changing outside signs to read, "Hall of Whores".

BioShock Infinite[]


Wanted for treason.

Main article: BioShock Infinite

After learning about Comstock's mechanical soldiers, Slate and his men desperately seek to die "as soldiers" gloriously in battle, and Slate considers Booker DeWitt to be the man for the job.

Booker and Elizabeth travel to the Hall of Heroes to obtain the Shock Jockey Vigor. Slate leads Booker to two exhibits within the museum -- the Wounded Knee Massacre and Boxer Rebellion exhibits -- where Comstock features prominently as a war hero. Once Booker and Elizabeth reach the exhibits, they are attacked by squadrons of soldiers, whom Slate sends to their "honorable" deaths.

"You're not done here, soldier! Eat everything that's on your plate! Finish it!"

Slate continues to test Booker, having him destroy Comstock's Motorized Patriots to prove his capabilities as a true soldier. Slate then reveals that he is in possession of Shock Jockey, and creates a series of electric traps while Booker battles a final group of soldiers. With the battle finished, Booker pursues a weakened Slate to obtain the Shock Jockey he needs.

Slate then gives Booker one final order, handing him a pistol and telling him to "finish it". If Booker follows through, Slate's last remarks are about Booker not changing and still being a true soldier. If spared, Slate angrily yells at Booker, calling him a "Tin Man". In the second scenario, Slate is subsequently captured by Columbian authorities and imprisoned at the Good Time Club, where he is found tortured into a catatonic state. Once again, Booker has two choices: kill him or leave him behind. If Booker kills him, Elizabeth will respond with "I guess that's what he wanted". If Booker spares Slate, Elizabeth wonders if his current catatonic state is a worse alternative to death.

In a parallel universe, where the Vox Populi have taken over Columbia, Booker joins forces with Slate at the Hall of Heroes. Together, they tear it down at the cost of their own lives. They are declared martyrs of the revolution, with Booker appearing on Vox propaganda posters.


BioI Motorized Patriot Toy with a Note from Slate

A note from Slate, visible after defeating the Motorized Patriot.

Slate holds a very high opinion of those within the military due to his own experience as a soldier. He respects individuals who have proven their merit, like Booker DeWitt and Lance Corporal Vivian Monroe. Consequently, he is infuriated that Comstock, a civilian with no military record, would receive "undue" glory for fictitious service in battle, while Slate and his men received little recognition for their sacrifice. More importantly, he is appalled by the Hall of Heroes memorial which he believes trivializes the actual event for the sake of stroking Comstock's ego.

Heavily disillusioned by Comstock's betrayal, Slate has become a fanatic, desperate for himself and his men to die honorably in a final blaze of glory. He, therefore, refuses to allow his men to die at the hands of the Motorized Patriots and instead forces Booker to fight them. His abuse of Shock Jockey results in the Vigor's crystals growing from his skull like tumors, impeding his ability to make rational decisions and exacerbating his delusions, especially after Booker defeats the rest of his soldiers at the Hall of Heroes. He refers to Comstock's troops and Motorized Patriots as "Tin Men" (or "Tin Soldiers") to distinguish them from his concept of the ideal, true soldier. He holds the concept of soldiers dying in warfare as the ultimate honorable end, and freely embraces his death, even so much that if the player rejects the option to kill him after defeating him at the Hall of Heroes, he angrily chastises Booker for denying him an honorable death and equating him to a heartless "Tin Man". Overall, Slate is portrayed as a battle-loving warrior who finds solace and purpose through fighting.

Behind the Scenes[]

  • Ken Levine mentions how this was inspired by the pathologizing of soldiers in war: "You read newspapers that talk about "the fallen", rather than the dead young men. There’s a lot of pathologizing in our culture. Obviously it’s important, but it's also a disservice to the real experience. I mean, when you sanitize that experience -- the Pat Tillman notion. His family's saying "look, we honor him by telling the truth about him, about who he really was". Obviously the military is very important to them too, just not turning people into wax works".[6]
  • Slate has some small fragments of Shock Jockey crystals on the right side of his head, which might be the side effect of the said Vigor. This may be due to Slate being originally part of a rejected Vigor Junkie concept for Splicer-equivalent enemies, mentioned in The Art of BioShock Infinite.
  • Slate's fate and his words about either choice of sparing him or killing him foreshadow Booker's baptism, with either choice reflecting the lifestyle Booker/Comstock chose after accepting/denying the baptism. The encounter may also be seen as a symbolic representation of Booker's military past and the guilt he feels in relation to it. The phrase "wipe the slate clean" may have something to do with this, reflecting Booker's choice to either ignore his own past or confront it.
  • Slate's voice actor Keith Szarabajka also voiced Reed Wahl in Minerva's Den.
  • Slate has a fighting mechanism that was not used in the game. It was to be used against the player in the Hall of Heroes Courtyard. The mechanism includes high speed (faster than any enemy in the game), more health than most enemies and the Shock Jockey Vigor, essentially making him a boss. Using Console Commands, the player can trigger the mechanism by jumping out of the map and dying when Slate is present on the courtyard balcony. Slate will start running around the courtyard and throwing Shock Jockey traps all around the area and at the player. He will not drop any loot once killed.[7] Slate is immune to Possession and Bucking Bronco lasts on him for a much shorter time. Slate's Soldiers can be killed by Slate's hits and Slate has no collision with the player, meaning that one can run straight through him. He also has unique battle dialogue, heard when searching for Booker:
    • "Booker… [Stretched out]"
    • "Come on Booker. This is gonna take all day."
    • "Hear ye! Unbecoming for a cavalryman!"
    • "Is that you Booker?"
  • Slate shares similarities to Bill McDonagh. Both were devoted followers and believers of the men who built the cities they live in (Andrew Ryan and Zachary Comstock). Both had high positions within their city, and both eventually lost faith in that man, ending in their deaths. McDonagh was killed by Ryan, whilst Slate is optionally killed by Booker.
  • Cornelius Slate's character model can be unlocked in The Columbian Archeological Society's museum in Clash in the Clouds.
    • Slate's model is shown dual wielding a pair of Hand Cannons, which he is not seen carrying in the main game. However, in the Voxophone "Vox Contraband Inventory" Leander Manley orders Slate to "Put the guns down!" indicating Slate was carrying more than one weapon when he shot Manley.
  • Assuming Slate still had United States Army affiliation (even after he came to Columbia, it being under Federal control), he could have been attached to the 6th Regiment, U.S. Cavalry, which was historically present in Cuba at the Battle of San Juan Hill. Columbia's expedition to China during the Boxer Rebellion was not authorized by the United States Government and likely would have led to Slate being punished. When Columbia seceded from the United States, Slate would have officially left US Army service to become a high ranking officer in Columbia's newly formed military.
  • Both the "Wanted for Treason" poster and his leader card in Siege of Columbia show a much younger Slate, with a full head of hair and a dark beard, as well as missing the crystals growing from his skull. It is unknown whether this is a holdover from a pre-release version or intentional.
