Maresciallo Acerbi took part in the Spanish Civil War and served in the 25a Squadriglia, XVI Gruppo.
On 31 August 1938, CR.32s from the XVI Gruppo was indirectly escorting S.79 and BR.20 bombers to the front of Gandesa. At the end of the bombing, the fighters stayed in the area for interdiction. As in the previous week, the 25a Squadriglia had the duty to cover at 7,000m while the fighters from 26a and 24a Squadriglie flew at 5,500m.
The XVI Gruppo had taken off from Caspe at 16:30 and the eight CR.32s from the 25a Squadriglia flew in four sections of two aircraft:
1st section – Capitano Roberto Fassi (CO) and Tenente Raimondi
2nd section – Sottotenente Mario Visintini and Sergente Giuseppe Marini
3rd section – Sottotenente Bongiovanni and Sottotenente Mario Pinna
4th section – Sottotenente Emilio Marchi and Maresciallo Acerbi
Around 18:00, Capitano Giuseppe Majone (CO 24a Squadriglia) spotted six SBs in two formations of three each heading from the Segre river towards Villalba.
They were soon attacked by the Italian fighters. Suddenly, a dozen of escorting I-16s dived on the CR.32s of the 24a Squadriglia, but they were in turn jumped by the 25a Squadriglia, which soon was joined by all the Fiats. In the ensuing dogfight Italians claimed two Ratas destroyed and one probable, that were officially shared among the three Squadriglie, though one of the kills was unofficially credited to Capitano Fassi. Sottotenente Visintini (25a Squadriglia) shot at four I-16s, one of which “effectively and by short distance” and saw a Rata falling in flames, which considering the place and the time should be the one shot down by Capitano Fassi. Visintini’s Fiat was however damaged in the action.
As a result, the commander of the XVI Gruppo, Tenente Colonnello Arrigo Tessari, proposed that each Squadriglia should be creited with one shared destroyed I-16.
During his time in Spain, Acerbi was credited with one shared victory.
Acerbi ended the war with one shared biplane victory.
