Did British sailors really call Napoleon "Boney," as they do in the Hornblower novels?
Short answerYes; "Boney" was used alongside many ruder names.
NotesBritish sailors did call Napoleon "Boney," as characters do in the Hornblower novels, and many less polite names also circulated. The fictional dialogue therefore draws on a genuine hostile nickname rather than a modern invention. A family-friendly literary term represents only part of the language sailors used for an enemy leader. The short reply confirms the usage without cataloguing the ruder alternatives.
