During the first years of his military career he served in Africa, participating in the Rif War. He was stationed in the Regulares forces, composed of native Moroccans. By 1924 he already held the rank of lieutenant colonel and directed the Tabor of Regulares of Ceuta.[3] After the proclamation of the Second Spanish Republic, in 1932 he rose to the rank of brigadier general.[4]
In January 1937 he was appointed military commander of Melilla and head of the Eastern Constituency of Morocco, a position he held until December 1938.[8] During his period of command there were some 117 executions in the city.[8] He was also in charge of recruiting and organizing Moroccan mercenary units, which he sent to the Iberian Peninsula, where they played an important role on the battle fronts. During the course of the war he became director of the Granada Infantry Academy,[9] created for the training of military commanders. In December 1938 he was appointed Undersecretary of Public Order.[10]
In the context of the Catalonia Offensive, following the fall of Barcelona on 26 January 1939 he went to the city as Captain General of Catalonia, to take command of the occupation forces.[11] When Minister of Propaganda, Dionisio Ridruejo, arrived in Barcelona with the idea of holding several political rallies, Álvarez-Arenas did not give him authorization for them to be held and told Ridruejo that the most important thing was to "restore the altars of the city".[12] Shortly thereafter, on 28 February, he was promoted to the rank of major general. In July he would leave his post in Barcelona and briefly assume command of the V Military Region [es], based in Zaragoza.[10]
Francoist dictatorship
In September 1939, the recently restructured government of Francisco Franco appointed him Inspector General of the Civil Guard.[13] During his mandate, in March 1940, the merger of the Carabineros within the Civil Guard took place,[14][15] and the title of Director General was reinstated for the leadership of the body.[n. 1] He also proceeded to relentless repression and purification of the body,[17] expelling all elements not considered attached to the Francoist regime. He left the position in April 1942.[13]
