This was a very cruel way to die and it was used to convince a prisoner who refused to give a plea of innocent or guilty to change their mind. If no plea was given then a trial could not take place. Pressing took place inside prisons like Newgate or the fleet. The accused was laid on a table and had another table put on top of them. Then lead, rocks and weights were put on until they either decided to plea or were crushed to death.
The prison guards or ‘Keepers’ fed the victim with ‘Three morsels of barley bread without drink for the first day and as much filthy water as they like if they survived to the next day.’
