The Iniquities of History is one of the side quests available in Red Dead Redemption 2. Here, your goal is to help one of the citizens of Rhodes. Arthur has to recover a few items from an abandoned farm. Our walkthrough has all the locations of the objects.
Meet with Jeremiah Compson in Rhodes. Promise him that you will recover the items from his family house.
Head to Compson's Stead. Get inside the building. Arthur has to find three items. One of them, the Antique Pocket Watch, lies on the green chimney (presented in the picture above).
Examine the photography standing on the larger chimney. Two bandits should appear in the building - defeat them. You don't have to fight with them using your knife. You can shoot them. One of the enemies drops Compson's Pistol.
The last item is in the basement. Go back to the place with the large chimney. Take a look at the trapdoor presented in the picture above. Use any of your weapons to destroy the lock. Go down into the basement.
Find the Ledger presented in the picture above. Leave the building or keep exploring it (you can find, i.e. a Cigarette Card).
Go to Compson's camp and give him all the items.
