During the dictatorship of Primo de Rivera he maintained the clandestine contribution, helped distribute Solidaridad Obrera and got involved in different cultural activities.

He published some articles in the CNT's newspaper, Solidaridad Obrera, joined the Poblenou defense committee and accepted responsibilities in the Wood Union, of which he was appointed president in 1932.

[2] The strike began on November 14 and ended in mid-April of the following year, its duration was due to the fact that the conflict was not reduced to a labor issue (It was understood that the requests were very moderate and would be accepted without problem[3]), but was part of the power struggle between the CNT on the one hand and the UGT and the state on the other, entities that the anarchist union did not recognize.

During his time in prison, he became friends with García Oliver, with whom he would show great ideological affinity and would be the one to later introduce him to the Nosotros group.

Upon leaving prison at the end of 1933, he joined the group together with Durruti, García Oliver, Francisco Ascaso, Gregorio Jover, Ricardo Sanz, José Pérez Ibáñez and Aurelio Fernández.

[7] He was present at the meeting that representatives of the CNT had with Lluís Companys and at the plenary session in which it was decided to collaborate with the other political forces.

[8] Once the fight in Barcelona was decided, the Committee of Antifascist Militias was formed, which ordered Ortíz to organize a column of militiamen to occupy the towns between Zaragoza and Caspe.

[10] Ortíz participated in the extraordinary plenary session of unions in Bujaraloz which agreed on the creation, functions and powers of the Regional Defence Council of Aragon.

[11] During the process of militarization of the militias, which was subject to the columns accepting the change, he defended it due to the urgent need to obtain weapons for the front.

[12] Maneuvers of the communist 11th Division eventually led to the dissolution of the Council of Aragon, of the collectives, the imprisonment of Joaquín Ascaso and the repression of the libertarian movement in the area.

His destination was pending until December 1937, at which time he joined the Popular School of the General Staff, from which he left as an officer in February.

The Pyrenean position was precarious and Ortiz fundamentally believed that the Communist Party of Spain and even his own organization were setting traps for him to die.

[18] They went to Paris where they survived off the solidarity of colleagues and acquaintances, because after their flight from Spain and government positions they were expelled from the CNT and stopped receiving the aid they provided.

[20] He was released after the Allied invasion of North Africa, and he enlisted in the Free French Army as a volunteer for the entire duration of the war.
