Peccavi
Charles Napier was supposed to have despatched to his superiors the short, notable message, “Peccavi”, the Latin for “I have sinned” (which was a pun on I have Sindh). This pun appeared in a cartoon in Punch magazine in 1844 beneath a caricature of Charles Napier. The true author of the pun was, however, Catherine Winkworth, an English girl then in her teens, who submitted it to Punch, which then printed it as a factual report. Later proponents of British rule over the East Indians justified the conquest thus: “If this was a piece of rascality, it was a noble piece of rascality!”
