Bounty: Lost Soldiers (The Witcher 3: Wild Hunt)

It is necessary to clear one village from level 23 ghouls, I don’t remember its name

The same quest is not activated, maybe it's not a quest but just an announcement, no idea.

It turns out that it is given by the quartermaster Eggebrach at the parking lot of the Nilfgaardian army (on the map on the right at the bottom of the giant camp)
