Division (former Ascaso Column) and the 29th Division of the POUM, commanded by Rovira, didn't cancel their proposed march on Barcelona until the head of the Republican Air Force in the Aragon front, Alfonso Reyes, threatened to bomb them if they pressed on with their plan. By five o'clock in the afternoon, several anarchists were killed by the police near the Via Durruti (current Via Laietana). The POUM began to support resistance publicly. In shootings occurring that day, the well-known libertarian Domingo Ascaso, relative of Francisco Ascaso and president of the Regional Council of Defense of Aragon Joaquín Ascaso, was killed.

At about five o'clock, the anarchist authors Camillo Berneri and Francesco Barbieri were arrested by a group of twelve guards, six of them members of the local police and the rest from the PSUC. Both were murdered during their arrest. The climate of alarm
