The Fate of Every Crewmember

This is a list of every crew member, along with their portrait and cause of death. Obviously, spoilers ahead.
There are multiple options that will work for some crew members, the ones in this guide are what I discovered while playing. Feel free to leave a comment if you discovered another method of death that works, and I may get around to verifying them and updating the guide in the future.

@AthullNexus Well the surgeon is the same guy who gave you the book and watch, which he says to mail back to him in Morroco(which is in africa), and during one of the chapters you can see him and the ladies in a boat escaping

[AthullNexus]

How are we supposed to know that the surgeon and the ladies ended up in Africa?

[Drawoon]

checking your list against my two playthroughs, I've got a few different ones:

Charles Miner, Eaten by a beast
Charles Miner, Torn apart by a beast
James Wallace, Decapitated by a beast
Winston Smith, Clawed
Duncan McKay, Fell overboard
Finley Dalton, Eaten by a beast
Finley Dalton, Torn apart by a beast
Omid Gul, Fell Overboard
Jie Zhang, Decapitated by a beast
Wei Lee, Eaten by a beast
Nicholas Boterill, Spiked by a beast
Nathan Peters, Fell overboard
John Naples, Killed with a sword by Fillip Dahl
Abraham Akbar, Crushed by a cannon
William Wasim, Crushed by a beast
Alexander Booth, Fell overboard

[Ytse Frobozz]

I thought they were all eaten by Robert Witterel

[Hakneil]

I had a fun time working out everybody's death, but eventually towards the end it was just too much of a hassle to figure out who a bunch of seaman were specifically, so this guide really helped on that regard.

[Sabotage]

For those that drowned by beast/fell overboard and "disappeared" in Chapter IX, they and their boat can be seen flying through the air in the last memory they appear in where Maba perishes. No need for guesswork, just identify the 9/12 people in the memory that are still on the Obra Dinn(or look at the previous memory where they're seen getting into the rowboat), and you know who the 3 being tossed into the sea are.

[Steb]

I think all the instances of "Speared by a beast" I put as "Spiked" and it was accepted.

[kindly9]

The fucking illustrator was not "drowned", what the hell have you been taking?

[identifiedasbeingdisrespectful]

Wolff and Shirley can also be shot by Abraham Akbar, Seaman. He did actually light the cannon. You can see him with a lit wick on the f use in their death scene. This will change your ending report to fining Akbar for murder as well.

For me Fillip Dahl was poisoned
