>In August of the same year, after some negotiations with the French government, three fully armed D.371s arrived in Barcelona, piloted by the mercenary pilots M. Poulain, René Halotier and Henri Rozés. They saw action as escorts of a bombing raid against Talavera de la Reina, Toledo that destroyed the headquarters of General Juan Yagüé. These three D.371s had successfully defended their bombers against the attacks of six German Heinkel He 51 biplane fighters - an older-design aircraft with inferior performance.
>The Squadron España operated with these aircraft until the arrival of the modern Polikarpov I-15 and I-16, at which time the three Dewoitine 371s were withdrawn from the front and continued as training aircraft. However, they reappeared later in some squadrons and one is known to have flown with the 71 Fighter Group by the Yugoslav (Slovenian) volunteer pilot Josip Križaj. All Dewoitines left were practically destroyed after having been bombed by the Legion Condor aircraft in the airfield of Bañolas.
