On 14 March 1757, Admiral John Byng was shot by a firing squad at Portsmouth. He had arrived at Minorca with too few ships, fought an indecisive battle, and failed to save the island from the French. He was the first and last British admiral to be sentenced to death. The government may have sought a scapegoat.
Voltaire satirized the execution in his novel Candide. Candide watches an admiral shot at Portsmouth and is told that in this country it is good to kill an admiral from time to time, pour encourager les autres, to encourage the others.
