Crushing by elephant
The elephant would step upon the head of the condemned, the one commanded to die. Usually, handlers trained the elephant to put its large foot gently on the person's head. At this point, witnesses looked under the elephant's foot to make sure the prisoner was the one who committed the crime. Often, the condemned would scream and beg the witnesses to say it was not him.  If a witness stated this was not the criminal, they would probably commit perjury.  Perjury means lying at a trial.  In those days rulers could punish perjury with death.  Few witnesses denied the condemned was the criminal, because then the elephant may crush them instead.  Then the mahout, or elephant driver, gave the order, and the elephant would push down with its weight.  The skull broke and the foot crushed the head flat.
