With his jealous suspicions growing, Woyzeck confronts the drum major, who beats Woyzeck up and humiliates him. Finally, Woyzeck stabs Marie to death by a pond. While a third act trial is claimed by some, notably A. H. J. Knight and Fritz Bergemann, to have been part of the original conception (what may be the beginning of a courtroom scene survives), the fragment, as left by Büchner, ends with Woyzeck disposing of the knife in the pond while trying to clean himself of the blood.
