A weaver’s son from Picardy who enlisted in 1762 and was a captain in the National Guard in 1789, Tuncq was sent to Luçon in June 1793 and defeated much larger Vendéan forces there on 30 July and again on 14 August, concealing his artillery and counter-attacking the centre. He forbade his men to pillage, which made him unpopular in his own camp, and accused his commander-in-chief Rossignol of incompetence. The quarrel became a proxy for the struggle between the Dantonist and Hébertist factions: two representatives kept him in post and decreed Rossignol’s dismissal, others annulled it, and the Convention decided for Rossignol. Tuncq was suspended and arrested in September 1793 and remained in prison until after Thermidor. He died at the Val-de-Grâce in 1800 of injuries from a fall.
