On 20 November 1944, Guingouin was seriously injured in a car accident (he suggested that his vehicle had been sabotaged) and hospitalised at Limoges.
In 1947, Guingouin lost the mayorship of Limoges to a socialist, Léon Betoulle, who had been mayor of Limoges before the war, while his old rival, the French Socialist Party (SFIO) socialist Jean Le Bail,[REF] who was despised by all the "genuine" members of the resistance,[REF] became deputy for Haute-Vienne.
