[4][5] Peine forte et dure (Law French for "forceful and hard punishment") was a method of torture formerly used in the common law legal system, in which a defendant who refused to plead ("stood mute") would be subjected to having heavier and heavier stones placed upon his or her chest until a plea was entered, or as the weight of the stones on the chest became too great for the condemned to breathe, fatal suffocation would occur.
But, in case of High Treason, the Criminal's Estate is forfeited to the Sovereign, as in all capital Crimes, notwithstanding his being pressed to Death.The most famous case in the United Kingdom was that of Roman Catholic martyr St Margaret Clitherow, who, in order to avoid a trial in which her own children would be obliged to give evidence, was pressed to death on March 25, 1586, after refusing to plead to the charge of having harboured Catholic priests in her house.
Several hardened criminals, including William Spigott (1721) and Edward Burnworth, lasted half an hour under 400 pounds (180 kg) before pleading to the indictment.
Such instruments were finely threaded and variously provided with spiked inner surfaces or heated red-hot before their application to the limb to be tortured.
Peine forte et dure is referred to in Arthur Miller's political drama The Crucible (1953), where Giles Corey is pressed to death after refusing to plead "aye or nay" to the charge of witchcraft.
In the 1996 film version of this play, the screenplay also written by Arthur Miller, Corey is crushed to death for refusing to reveal the name of a source of information.
In the 2017 BBC One series Gunpowder the public execution by crushing of the fictional Lady Dorothy Dibdale (based on Margaret Clitherow) is shown in graphic detail.
