As after long talks, with the intervention of the Civil Governor, the fired workers were not reinstated, their coworkers began a strike on Tuesday, January 5 and the Unión General de Trabajadores (UGT) strike committee invited "all conscientious citizens" to join the "run over" workers and "to ask for our bread and that of our children, which those heartless bosses want to snatch from us”.
When the crowd saw the Civil Guard, they apparently burst into hostile shouts against them, calling them "lackeys of capitalism" and asking for the dissolution of the body.
The result was six dead men and five women (among them a mother and her four-year-old son, and a seventy-year-old woman); eleven women and nineteen men injured (including a five-year-old boy whose leg had to be amputated and several elderly people), of whom five were rendered useless for work; and a civilian slightly wounded by a bullet.
[5] In the conversation that Sanjurjo had with the President of the Government, Manuel Azaña, in which the latter informed him of his dismissal as director of the Civil Guard, Sanjurjo did not speak of the atrocities committed by his subordinates in Arnedo, but instead blamed the “socialist town halls”, where “the worst of each house” had gotten into, “undesirable” people who “encourage disorder, intimidate owners, cause damage to properties and necessarily clash with the Civil Guard”.
[6] The military court that on January 30, 1934, tried in Burgos the lieutenant of the Civil Guard who gave the order to shoot in Arnedo acquitted him "of the crime of homicide and injuries due to reckless negligence due to lack of sufficient evidence to appreciate what he had committed" noting that " the same circumstance exists with respect to charges on the Civil Guard force under his orders".
