With reasonable evidence to suggest that Ginger knows more than he was willing to say about the raid on Neuhof, you must now track him down and discover the truth. Jakub mentioned that he is good friends with the charcoal-burners to the south, so you should begin your search by questioning them.
Note: Speak to Captain Bernard in the courtyard of Neuhof before you ride to the charcoal-burners camp. Informing him of the progress of your investigation will save you an earful of admonitions later.
Although the charcoal-burner in the southern camp does not know who Ginger is, if you manage to persuade him to talk he will let you know that others have been looking for him. The others did not seem like they were inquiring with amiable intent, so the spokesman urges you to speak to the charcoal-burners north of Neuhof.
The last charcoal camp that you will be directed to can be found north west along the river from the northern camp. Keep to the path on the south side of the river to avoid any trouble with bandits along the way.
Note: Be sure to equip some heavy armour for the fight ahead. Remember that any vulnerabilities in armour can result in a swift death when facing multiple foes.
You can speak to the bandits briefly, but regardless of the options the discussion will end as they attack you. Kill them both and report back to the charcoal-burners.
Go to the abandoned hut that is marked on the map. You will find Ginger hiding inside.
With the story from Ginger's perspective clarified, he wants to return to Neuhof. Concerned about his tarnished reputation, he asks Henry to tell the Neuhof inhabitants the truth, and to ask if they will allow him to return.
Once you have confirmed with Zora that Ginger can return, go back to the hut and let him know.
With Ginger now thoroughly exhumed from his pickle, you can return to Captain Bernard at Neuhof and inform him of everything that has transpired.
