his is the only non-medieval, European torture on our list. The water torture was a favorite among Japanese POW guards during WWII. The victim was first bound with barbed wire and his mouth stuffed with rags. Next, the guards would snake a tube down the victim's nasal passage and bloat his belly with water. Once that was finished, the guards would kick and beat the poor sap's midsection until his stomach lining burst and and death ensued.
