I imagine it must have been difficult getting to sleep, with a sore welted bottom, throbbing and stinging into the night. The trauma may have even contributed to or caused the bedwetting, for which the boy would then be caned again. How cruel and sadistic.
It seems like schoolmasters at boys’ private schools in the Edwardian period could get away with dishing out as much corporal punishment as they fancied, providing they didn’t cause death or lasting physical damage. But what about the psychological, and psycho-sexual damage? It seems that was not an issue in those days.
