In the Republican faction militias are also formed from the first days of the civil war. For example, in Asturias, militant socialists formed the Asturian Miners Column on July 18, in order to counter the coup in Madrid. However, when he reached Benavente, Zamora, he turned around when news was received that the military, under the command of Antonio Aranda Mata, had revolted in Oviedo. In Huelva, the Riotinto Mining Column tried to quell the uprising in Seville, but it was betrayed by the Civil Guard which ambushed them in Camas.
