Witnesses have stated[citation needed] that on 4 November German soldiers carried explosives into the town hall tower, and also into two churches, a windmill, and dairy factory in Heusden. NCO (non-commissioned officer) Bottnick, who was probably following orders from commander Pfühl, a mining engineer, undermined the eastern part of the tower, ensuring that it would collapse on the town hall, not on the street. Later, these events were investigated by the British Civil Affairs. However, this has never resulted in the trial and punishment of Pfühl, Bottnick, and their accomplices.
