In the spring of 1892, after the death of his father in law, Pallàs and his family returned to Barcelona. With their inheritance, they opened up a textiles shop. Pallàs left the enterprise to return to work in printing, but he was dismissed over his political activism. That summer, he briefly moved to Paris, where he was swept up in the commotion around the trial and execution of the French anarchistRavachol. Upon his return to Catalonia, he established an anarchist publication called Ravachol in Sabadell. He and his wife Àngela spent most of their time working, making clothes with Singersewing machines. According to his neighbours at the time, he rarely spoke about politics; even his wife did not know about his anarchist ideas.[2]
Pallàs unsuccessfully attempted to assassinateArsenio Martínez Campos, the Captain General of Catalonia. Martínez Campos had been responsible for violently repressing the January 1892 Jerez uprising and execution of four Jerez anarchists. In revenge, on 24 September 1893, Pallás threw two bombs at Martínez Campos, but missed and killed at least two bystanders.[3] Martínez Campos suffered minor injuries. Pallàs did not seek to escape.[4] After being tried by a court martial, Pallás was executed by firing squad on 6 October 1893.[3] His final words were, "The vengeance will be terrible." A month later, his friend would avenge Pallás's death with the Liceu bombing, killing over a dozen.[4]
