Following the seizure of Zaragoza Comín played a politically vital role, transforming the Aragon insurgency from defense of the Republic against anarchy, as Cabanellas would have had it, into a monarchist, ultra-conservative and fanatically Catholic crusade. Under his command the Carlists were tearing down republican flags and replacing them with monarchist banners; he personally introduced Virgen del Pilar painting into the ayuntamiento hall, while the city elated in religious celebrations. Comín threw himself into organizing the new Requeté battalions; in late July the first sub-units of Tercio de Nuestra Señora del Pilar were formed, later on followed by another Aragon battalion, Tercio de los Almogávares. In the autumn Comín was incorporated into command structures of the Pilar tercio, though given his lack of military training it is not clear what exactly his position was. He spent December 1936 in line on the Madrid front, though it is not known what was his unit at the time; also later on he served in the frontline troops on the on and off basis, present among soldiers entering Teruel when re-taken by the Nationalists in early 1938. He suffered combat wounds; noted for demonstrating bravery which bordered imprudence, Comín was admonished for taking unnecessary risks.
