When Franco's military conspiracy flared into revolt in July 1936, Asensio Cabanillas and Colonel Sáenz de Buruaga easily secured Tétouan for the rebels. In the first month of the war his column, fighting alongside Juan Yagüe's troops, made an impressive forced march from Seville to Madrid, storming and taking the cities of Badajoz, Toledo, and Talavera. His bloody advance into the University City during the Siege of Madrid would mark the farthest Nationalist advance against the city until the end of the war. At the Jarama his column spearheaded the attack across the river but was stalled thereafter by the International Brigades.
