Letters of fire and sword were a Scottish legal instrument. If a criminal resisted the law and refused to answer his citation, it was considered treason in the Scottish courts; and “letters of fire and sword” were sent to the sheriff, authorising him to use either or both these instruments to apprehend the contumacious party.Dictionary of Phrase and Fable, E. Cobham Brewer, 1898, page 464, Fire and Sword
