In the context of the Spanish Civil War, he was interrogated and threatened by the anarchists in Aragon after being accused of helping priests hidden in the town of Maella to escape to France. Some versions stay that he was allowed to return to Catalonia after the intervention of the French Consulate in Barcelona. Other versions stay that he was detained by the anarchist and was to be shot but was saved by other anarchists that knew him from the exile during Primo de Rivera's dictatorship. After the May Days of 1937, when the Catalan police became controlled by the Spanish Republic government he moved again to Perpignan in Northern Catalonia. However, he kept collaborating with the Catalan government and traveled secretly to Barcelona in several occasions.
