The Companions of Jehu were formed in the Lyon region of France in April 1795 to hunt down Jacobins implicated in the Reign of Terror.[1][2] It is possible that they were founded by the Marquis de Besignan,[3][4] who also founded royalist underground groups in Forez and Dauphiné with the Prince of Condé in 1796.[5] Their victims are believed to have numbered at least in the hundreds. They were made famous by the 1857 novel The Companions of Jehu by Alexandre Dumas which presented a highly romanticised account of them.[6]
