Giorgio Di Giulio was from Tocco Casauria (Pescara).

In the middle of September, Sottotenente Carlo Albertini of the 366^a Squadriglia, 151^o Gruppo, and Maresciallo Di Giulio were assigned to the 91^a Squadriglia, 10^o Gruppo. This unit was at the time equipped with Fiat CR.42s.

On 23 December, 17 CR.42s from the 10^o Gruppo took off at 08:30 to escort ten bombers from the 15^o Stormo, which had taken off from T4 and bound to attack armoured vehicles around Sidi Azeiz. The escort included five fighters from the 91^a Squadriglia (Maggiore Carlo Romagnoli, Capitano Vincenzo Vanni, Maresciallo Di Giulio, Sergente Maggiore Giovanni Casero and Sergente Luigi Ferrario), four from the 90^a Squadriglia (Tenente Giovanni Guiducci, Tenente Franco Lucchini, Sergente Alfredo Sclavo and Sergente Luigi Contarini) and eight from the 84^a Squadriglia (Capitano Luigi Monti, Tenente Antonio Angeloni, Sottotenente Luigi Prati, Sottotenente Bruno Devoto, Sergente Domenico Santonocito, Sergente Roberto Steppi, Sergente Corrado Patrizi and Sergente Piero Buttazzi).
The formation was attacked by six Hurricanes and the Italian pilots claimed one confirmed shot down, another as a probable and a third was obliged to force-land among its own armoured vehicles (the 90^a Squadriglia's pilots expended 455 rounds of ammo). The three victories were credited as shared among all the participating pilots. The Italian fighters landed back at Z1 at 11:05 with Sergente Ferrario's aircraft damaged. The bombers (led by Colonnello Napoli) landed back at base at 10:30, with only one machine damaged by the Hurricanes.
The Hurricanes were from 274 Squadron, which was out on a morning patrol to cover a line Sidi Omar-Sollum-Buq-Buq with twelve machines taking off with 15 minutes intervals. From the reports of the returning pilots, it seems that fighters from 73 Squadron were present even if this is not reported in 73 Squadron documents.
Pilots taking part were Pilot Officer Stanley Godden (P2638) (06:15-09:15), Pilot Officer Ernest Mason (P3722) (06:30-09:30), Second Lieutenant Bester (N2624) (06:45-09:35), Flying Officer Thomas Patterson (P2544) (07:00-09:45), Flight Lieutenant John Lapsley (V7293) (07:20-09:50), Sergeant Dean (V7423 (07:30-10:30), Second Lieutenant Robert Talbot (P3721) (07:45-11:05), Pilot Officer Garland (P 3977) (08:10-11:15), Sergeant John Clarke (N2627) (08:20-11.00), Flying Officer C. F. Greenhill (P5176), Pilot Officer Strange (N2628) (09:50-12:50) and Flight Lieutenant Peter Wykeham-Barnes (P2638) (10:00-13:00).
Pilot Officer Mason had a field day; firstly, he intercepted ten SM 79s in two vics of five at 07:30 (strangely enough he wrote 09:30 in his CFR) when he was 10 miles south-west of Gambut at the height of 12,000 feet. He discovered the ten bombers 2000 feet below and dived from above, past the escort on no. 4 of the rear vic. He reported:

no4 of rear vic dropped back but later observed to rejoin formation. Small a/c seen burning on ground (unreadable) miles south of Bir Chleta. Believed to be CR 42 claimed by 2nd Lieutenant Talbot. 12 CR 42s in 4s and 2s were on port flank 1000 feet above and behind. After carrying out this attack I climbed above and carried out another attack.

enemy aircraft damaged. Unable to observe further as I got involved with the escort and was also fired on by our own troops. Burning S79 observed on ground in this approximate position by Pilot Officer McFadden no 73 Squadron. 12 CR 42s in 2s and 4s were 1000 feet above on port flank. The escort had observed my approach as this was my second attack and closed in on main force that jettisoned bombs. After breaking off attack I got involved with 2 of the escort at 1000 feet and was considerably embarrassed by tracers and pom-pom fire from our own troops.

port engine caught fire a/c climbed to 200 feet and then hit ground with wheels and flaps up. Bounced twice and went on nose. I circled a/c (E) and only one man (pilot) emerged from front exit.

1 CR 42 shot down later burst in flames 1 S79 initial attack dropped out of formation and did not rejoin. Determined attacks from escort prevented me from observing results of combats with S 79. While the CR 42s attacked immediately the main formation increased speed but kept formation and opened fire.

Di Giulio ended the war with 1 shared biplane victory.
