Raul Galli was from Soragna (Parma).

Sergente Galli took part in the Spanish Civil War where he served in the 1^a Escuadrilla de Caza del Tercio.

On 27 September 1936, Sergente Galli of the 1^a Escuadrilla de Caza del Tercio shot down a Dewoitine D.372 near Toledo.
This aircraft was one of 14 examples originally built for the Lithuanian government, which rejected them and instead delivered to the Spanish Republic from early August 1936. It was flown from Toulouse to Barcelona by French pilot Bois on 9 August.

In the afternoon on 27 October, Sottotenente Adriano Mantelli of the 1^a Escuadrilla de Caza del Tercio and his wingmen attacked a formation of five unescorted Breguet XIXs between Peguerinos and El Escorial. Sottotenente Mantelli claimed one of the Breguets and shared in the destruction of three others with Sergente Maggiore Bernardino Serafini and Sergente Galli.
Sergente Galli’s CR.32 was hit by return fire, however, severing its aileron control lines. Nevertheless, Galli managed to nurse his damaged fighter back to Ávila and perform an uneventful landing, in spite of the fighter’s poor handling.
All four of the aircraft destroyed belonged to the last Republican unit to be equipped with the Breguet XIX on the Madrid front, Escuadrilla Gonzalez, as the rest had been decimated by the all-conquering CR.32. The commander of this unit, capitán Gonzalez Martin, had in fact been flying the first aircraft to be shot down on this day. He and another pilot, and their respective rear gunners, all lost their lives, while the remaining two crews survived emergency landings in Republican territory. The one surviving Breguet XIX returned home to Alcalá de Henares with only the pilot on board, as the gunner, Ramos, had taken to his parachute over the Republican zone near El Escorial in the belief that his aircraft was falling out of the sky following the apparent death of his pilot! It was Ramos who had hit Galli’s fighter, forcing him to break off his attack.

Galli claimed 1 biplane victory during the Spanish Civil War.
