Adamo Giuglietti was from Perugia.

Sergente Giuglietti took part in the Spanish Civil War using the nom de guerre ’Guglielmotti’.

At dawn on 14 August 1936, the Italian freighter Nereide entered the port of Melilla, on the Mediterranean coast of Spanish Morocco. This important town had been occupied four weeks earlier by Nationalist forces led by general Franco himself. The vessel’s cargo consisted of 12 CR.32s, which had been embarked in the Italian port of La Spezia a week earlier.
As well as spare parts for the Fiat fighters, the ship had also transported 18 volunteers from the Regia Aeronautica to North Africa, their passports bearing false details. Amongst them were the first 12 Italian fighter pilots to arrive on Spanish territory. They were led by Capitano Vincenzo Dequal (’Paride Limonesi’) of the 1^o Stormo CT and his flight leaders were Tenente Vittor Ugo Ceccherelli (’Vaccarese’), also of the 1^o Stormo CT, Tenente Ernesto Monico (’Preti’) of the 4^o Stormo CT and Sottotenente Giuseppe Cenni (’Vittorio Stella’) of the 1^o Stormo CT. The remaining enlisted pilots were Sergente Maggiore Giuseppe Avvico (’Nannini’) the 4^o Stormo CT, Sergente Maggiore Bruno Castellani (’Ribaudi’) of the 6^o Stormo CT, Sergente Maggiore Sirio Salvadori (’Salvo’) of the 4^o Stormo CT, Sergente Angelo Boetti (’Ilacqua’) of the 1^o Stormo CT, Sergente Giuglietti (’Guglielmotti’) of the 1^o Stormo CT, Sergente Giovanni Battista Magistrini (’Marietti’) of the 1^o Stormo CT, Sergente Vincenzo Patriarca (’Boccolari’) of the 4^o Stormo CT and Sergente Guido Presel (’Sammartano’) of the 6^o Stormo CT. The groundcrew consisted of just three aircraft riggers and three mechanics.
After being welcomed by Spanish officers and the local Italian Consul, the pilots and groundcrew were immediately enrolled into the Tercio Extranjero with their equivalent ranks.

In the morning on 30 October, Sottotenente Adriano Mantelli of the 1^a Escuadrilla de Caza del Tercio and his flight consisting of Sergente Ligabò and Sergente Giuglietti, intercepted a formation of three Potez 540 bombers over Navalcarnero. Leading the Republican bomber formation was the second- in-command of the Escuadra Internacional (Escuadra N^o 4), Spaniard comandante Sampil, while the remaining two aircraft were flown by Bulgarian Zakharij Zakharev (’Volkan Goranov’) and Russian Ivan Proskurov. Zakharev’s (Potez 540 ‘N’) crew included three Spaniards (co-pilot, flight mechanic and a gunner), Petr Pavlovich Desnitskiy (lower turret gunner), Anatoli Ivanov (gunner) and leitenant Kuz’ma Demenchuk (navigator).
The Republican bombers were surprised and initially blinded by the sun when the CR.32s initially targeted Zakharev’s Potez, setting one of its engines on fire. The lower turret gunner Desnitskiy kept firing his gun even after he was hit, claiming an enemy fighter. He was pulled from his position and replaced by leitenant Demenchuk, who also was pulled from the turret just before the bomber crash-landed.
Proskurov attempted to assist his comrade by slowing down and positioning his aircraft between Zakharev and the opposing fighters. This courageous action won him the admiration of the Italian pilots, but it was ultimately performed in vain as the damaged bomber was doomed.
Although wounded in the leg by a bullet, Zakharev tried to nurse his stricken aircraft to the safety of Republican territory, but he and his Spanish co-pilot Pérez Sancho force-landed the aircraft in a clearing in No Man’s Land. All five crew managed to escape the wreckage and reach friendly troops with Zakharev, Desnitskiy and Demenchuck wounded by gunfire from the Italian fighters. A short while later Sottotenente Mantelli shot down Proskurov’s Potez over Republican territory. Like Zakharev, the skilful Russian pilot also managed to save the lives of his crew by carrying out a successful emergency landing in a vineyard near Getafe. Although Mantelli also was credited with the destruction of flight leader Sampil’s Potez, the latter had in fact made it back to base at Albacete.
Mantelli, like his wingmen, returned to Talavera to find that his CR.32 had been holed in several places by fire from Proskurov’s gunner, Vladimirov, who had continued to fire at the Italian fighter in spite of a serious wound to one of his hands.
The Potez 540 flown by Zakharev was flown from Toulouse to Barcelona on 15 September, before heading on to Madrid to be assigned to the Escuadra Internacional (Escuadra N^o 4).

Giuglietti claimed 1 shared biplane victory during the Spanish Civil War.
