General Sir Charles James Napier, the Commander-in-Chief in India from 1849 to 1851 is often noted for a story involving Hindu priests complaining to him about the prohibition of sati by British authorities.
“Be it so. This burning of widows is your custom; prepare the funeral pile. But my nation has also a custom. When men burn women alive we hang them, and confiscate all their property. My carpenters shall therefore erect gibbets on which to hang all concerned when the widow is consumed. Let us all act according to national customs.”
A classic.
