The Mercies of Knowledge is a side mission in Red Dead Redemption 2 that starts just outside of Saint Denis city.
There are at least six parts to this mission and it involves helping the professor successfully create his electric chair.
Here’s a walkthrough of The Mercies of Knowledge in RDR 2.
To start the mission, talk to the stranger located in the white area on the map above. He will ask you for some moonshine.
He needs a load of moonshine for his experiment.
The Mercies of Knowledge Part 2
To get information on wagons with moonshine, get to Rhodes Station where your friend Alden is. He is the station clerk.
Ask him about moonshine and he will tell you that there’s a wagon coming through Bluewater Marsh.
Get to the bridge in Bluewater Marsh and wait for the wagon to come.
The Mercies Of Knowledge Part 3
The exact location of where to wait for the wagon is shown in the map below.
After awhile, you can see the wagon coming. The location is also indicated in the map.
Steal the wagon
The wagon is accompanied by two riders as well. There are four people to kill in total.
Once you’ve eliminated them, take the moonshine wagon back to the professor at Saint Denis.
Return to the professor
Park the wagon in front of his house and you’re done for now.
The Mercies Of Knowledge Part 4
Now, you have to convince the police chief to allow the professor to demonstrate his electric chair in executing a criminal.
Find the police chief
Get to the location shown in the map below. There may be two different locations but I chose this one.
Enter the police office. You will find a lawman near the cells. Talk to him.
He will require that you pay $100 for the permit to use the electric chair. Negotiate with him.
He will reduce the permit to $50. Personally I just paid him. Maybe there’s a way to get it free if you had gone to the other location.
Just pay him if you’re feeling lazy and rich.
The Mercies Of Knowledge Part 5
Get back to the professor and give him the permit to use the electric chair.
There is one condition, i.e. you need a live subject for the permit.
The professor will then ask for your help to capture a bounty called Wilson J. McDaniels.
The Mercies Of Knowledge Part 6
Your role now is to get to the bounty and bring him back. He is located south of Moonstone Pond and north of Heartland Overflow.
His exact location is shown in the map below.
Find the bounty
As you get close, his exact location will be shown.
He is in a camp filled with many outlaws. Kill all of them but don’t accidentally kill him. It’s a bit tricky since he’ll be shooting at you as well.
He will run away once all of the others are dead.
Use a lasso to stop him and hogtie him. Stow him on your horse and get back to the professor.
Return to the professor
On the way, you may meet some of the people you stole the moonshine from. Kill them too. There should be three of them on horses.
Bring the bounty back to the professor and throw him in front of the professor.
And that’s it. The mission completes here. I’m not sure if there are more parts to this.
