He was a convinced Falangist. He began his involvement taking part in the Asturian miners' strike of 1934 as a reporter. He was awarded the above-mentioned prize, "Palma de Plata", due to his work. It is important to highlight his work as a journalist in the Falangist press and in the newspaper La Nación. He was imprisoned in the prison of Bilbao, Larrínaga, for crimes against the Spanish Second Republic, because of his work as a gunman for the Falange (the Spanish Falangist movement). He was present at the time of the uprising of the Nationalist army on July 18, 1936. When he was due to be transferred he escaped from the prison and fled to the national zone. In 1937, he traveled to Salamanca as a correspondent at the front for an interview with Manuel Hedilla, National Leader of the Falange, who tried to gain support against those who had a sense of entitlement due to their proximity to José Antonio Primo de Rivera. The situation in Salamanca had divided the Nationalists in two. The Hedilla supporters, under the command of Agustín Aznar, Sancho Dávila and Rafael Dávila Garcerán, were backed by the Germans. Furthermore, rumors were spread from the headquarters of Francisco Franco to destroy and discredit both factions, before they then presented themselves as saviours. According to his memories, Alcázar de Velasco intuits this and therefore proposes, at least twice, to murder Francisco Franco.
