^This. The 'Minstrel's Ballad' fights aren't the original battle, or even a 'real' battle, but just the player character's imagination fueled by their own memories of the 'original' battle and the Minstrel's personal embellishments to "make it more interesting." The DF description for them even states this outright, that "it is hardly an accurate retelling," and that listening to the Minstrel sing "you find yourself imagining yourself back at that fateful day in the Praetorium" or whatever. So yeah, the Minstrel fights are just in the player character's head effectively.
