How was king Louis XVII mistreated?

No one knows exactly how Louis XVII was treated in the Temple Prison. He was beaten to death and tortured and forced to sing "Revolutionary" anthems and was not allowed to pray or speak of his mother and father. He was even forced to speak against his parents. He was imprisoned in a small, dark dirty cell-which was possibly rat infested and was never given clean clothes, proper food and hygiene and had to sleep among his own feces. Louis XVII died in the prison tubercolosis after he was removed from the cell- his bones began to become very weak and his hearing began fading until he could no longer speak, he mostly perished from mistreatment and neglect.
