The Battle of Guadalajara and the defence of the skies over Madrid against Nationalist bombing raids during the capital's long siege would be the only scenarios where the loyalist air force took part in an effective manner. In other important republican military actions, such as the Segovia Offensive, the Battle of Teruel and the decisive Battle of the Ebro, where the Aviación Nacional was relentlessly strafing the loyalist positions with accurate low-level attacks, the republican military airplanes were practically absent from the skies. Moreover, when they appeared and attacked, they did so in an unorganized and inadequate manner that mostly failed to achieve positive effects.
