Enea Atti was born on 10 August 1915 in the USA.

In November 1940 Atti served in the 363^a Squadriglia, 160^o Gruppo Autonomo C.T., which was equipped with Fiat CR.42s. The unit was at this time operating over Greece.

On the morning on 14 November nine PZL P.24s from 23 Mira at Larissa undertook a patrol during which they were surprised by a pair of 363^a Squadriglia CR.42s, led by Tenente Atti. Although the Italians claimed one probable, the Greek fighters were able to scatter and evade their assault. The two Fiat pilots then spotted two Blenheims from 32 Mira on their way to attack Koritza and claimed one of these as a probable also.

At 08:30 on 8 January 1942, 19 CR.42s of the 3^o Gruppo, led by Tenente Colonnello Innocenzo Monti, took off from Ara Fileni to bomb and strafe the airstrip of Agedabia. Twelve MC.200s of the 150^o Gruppo, led by Maggiore Antonio Vizzotto, which had taken off at 08:30 from El Merduma, were their direct cover. Finally, eight MC.202s of the 88^a Squadriglia (6^o Gruppo) took off from Ara Fileni at 08:30 led by Capitano Dante Ocarso, to indirectly escort the whole formation.
The CR.42s reached the target at 09:00, flying at 1,000m in groups of three aircraft in echelon right; at the same height were the Macchi MC.200s, (flying in echelon right too) while the MC.202s were at 3,000m. While the Fiats were starting their dives, a formation of twelve P-40s was discovered. They immediately attacked the Falcos and one of the Curtiss was claimed shot down by Sergente Adriano Vezzi of the 155^a Squadriglia, who’s aircraft in turn was damaged. The Fiats of the 3^o Gruppo were able to complete the attack even if they didn’t claim to have inflicted heavy damage; a Bristol Blenheim destroyed and a couple of trucks left in flames with the use of 24 50kg bombs, 1335 rounds of 7,7 ammunition and 2846 rounds of 12,7 ammunition.
The 150^o Gruppo recorded a clash with 25 P-40s losing two MC.200s and one damaged while claiming two P-40s and two damaged with the use of 2050 rounds of ammunition. The two destroyed P-40s were shared between Maggiore Vizzotto, Tenente Atti (363^a Squadriglia), Capitano Domenico Bevilacqua (CO 365^a Squadriglia) and Sottotenente Fausto Filippi (365^a Squadriglia). The pilots of the lost MC.200s (MM6668 and MM5342), one of them wounded, parachuted and were able to regain the Italian lines on foot two, returning to their unit two days later.
The MC.202s reached the target at 08:55, in vics of three disposed in echelon right, at the height of ,3000 m. recording an intense AA reaction. Then they intercepted four or five P-40s that were attacking the CR.42s and forced them to flee. One of the P-40s was claimed shot down and a second probably so with the use of 1060 rounds of ammunition. The claims were shared among the eight pilots (Capitano Ocarso, Tenente Raffaele Giannuzzi Savelli, Sottotenente Alfredo Civetta, Sottotenente Roberto Sparapani, Sottotenente Roberto Sgorbati, Maresciallo GianLino Baschirotto, Sergente Maggiore Anano Barreo and Sergente Luigi Bartesaghi). The MC.202s landed back at base at 09:50.
Their opponents were ten Kittyhawks of 3 RAAF Squadron, which had taken off at 08:20 for an offensive sweep between Agedabia and El Agheila. They reported that they met 20 MC.200s, 15 CR.42s and G.50s and 8 Bf 109s (clearly the MC.202s), flying at 5000 feet. They started in pursuit and claimed seven shot down, five probables and three damaged. The claimants were Flight Lieutenant Edward Jackson (AK650) who claimed one MC.200 and three MC.200s damaged, Sergeant Ronald Simes (AK610) who claimed one CR.42 and two MC.200s, Sergeant Reginald Pfeiffer (AK619) who claimed two MC.200s, Flying Officer Jones (AK698) who claimed one Bf 109E and one Bf 109F as probables, Flying Officer H. H. Schaeffer (AK645) who claimed one CR.42 and one probable MC.200 and finally Flying Officer Richard Hart (AK617) who claimed one CR.42 and one Bf 109 E as probables. They lost Kittyhawk AK656 of Flying Officer Alan Baster (RAAF no. 400035), who was killed. The Australians all had landed again at 10:25
It seems likely that the Folgores attacked only part of the Australian formation while the others fought against the Macchi MC.200s and the CR.42s.
At the end, even if the escort wasn’t able to avoid the attack on the Fiats, it permitted them to come back without losses after completing their mission but it is necessary to note that the eight MC.202 were engaged by only four or five P-40s. The Australian pilots, back at base noted that the MC.200s were able to out-turn their Kittyhawks, which were less manoeuvrable than their predecessors were.
It is not possible to state who shot down Baster even if from the very detailed report submitted by Vezzi once back at base it seems that he was the responsible.

On 8 March 1942, ten MC.200s from the 150^o Gruppo, led by the 363^a Squadriglia CO Capitano Luigi Mariotti, were providing close escort for 12 German Ju 87s in an attack on Tobruk harbour at 16:30 when they were attacked by 12 Kittyhawks (six each from 450 and 3 RAAF Squadrons) led by Flight Lieutenant ‘Nicky’ Barr of 3 RAAF Squadron. German Bf 109s were flying top cover, but for unknown reasons they did not intervene. The 150^o Gruppo was hard hit and five MC.200s were lost and three pilots killed with two taken prisoners; Tenente Atti (363^a Squadriglia, KIA), Sergente Maggiore Enrico Micheli in MC.200 MM6490 (363^a Squadriglia, POW), Sergente Maggiore Leopoldo Ierai in MM5333 (365^a Squadriglia, POW), Sergente Raffaele Badalassi in MM5332 (363^a Squadriglia, KIA) and Sergente Ugo Rodorigo in MM6661 (363^a Squadriglia, KIA). Two badly damaged Macchis, one of them piloted by Tenente Ugo Drago, managed to land safely at Tmimi and Martuba.
The Australians reported that at around 17:00, six Kittyhawks each from 450 and 3 RAAF Squadron, led by Flight Lieutenant ‘Nicky’ Barr (Kittyhawk AK903/CV-L) took off on a freelance patrol over the battle area with the aircraft from 450 RAAF Squadron acting as top cover. Taking part from 3 RAAF Squadron were Flying Officer Peter Giddy (AK876), Pilot Officer Victor Curtis (AK622), Sergeant W. A. Beard (AK623), Flying Officer H. G. Pace (AK712) and Sergeant T. E. Packer (AK898). Pilots from 450 RAAF Squadron were Flying Officer Thompson (895/K), Sergeant F. W. Beste (493/W), Sergeant Raymond Shaw (AK592/DJ-P), Sergeant James (R641), Sergeant Donald McBurnie (AK717/V) and Sergeant Raymond Dyson (AK732/DJ-A).
Enemy aircraft were sighted 15 miles south of Tobruk and contact was made. The enemy were a reportedly 15 Ju 87s in vic formation with a close escort of nine MC.200s and MC.202s in a very tight formation made up of two echelons of five and four aircraft, and two Bf 109s over Tobruk. The Italians mistook the Kittyhawks for friendly fighters and were slaughtered. Initially the 450 RAAF Squadron remained as top cover and 3 RAAF Squadron attacked. Flight Lieutenant Barr claimed his ninth kill during this action when he accounted for a MC.202 northwest of Tobruk, with another claimed as a probable and two damaged MC.200s. Flying Officer Giddy claimed a Ju 87 and a MC.200 15 miles north of Tobruk while Flying Officer Pace claimed a MC.200. Pilot Officer Curtis claimed a Ju 87 and a MC.200 north-west of Tobruk while Sergeant Beard claimed a damaged MC.202.
450 RAAF Squadron reported that the contact was made at 17:25. In the ensuing engagement Sergeant Beste and Sergeant McBurnie each claimed a MC.200 over Tobruk while Sergeant Shaw claimed a MC.202. Sergeant Dyson claimed a probable MC.200 while Flying Officer Thompson claimed a damaged MC.200. It seems that the combat was fought on a low altitude since Sergeant McBurnie lost the wingtip on his Kittyhawk after contact with the sea. Another Kittyhawk (from 450 RAF Squadron with an unknown pilot) was damaged (Cat 1) by machinegun bullets. By 18:25 all the Australian fighters had returned to base.
112 Squadron reported that Flight Lieutenant Gerald Westenra led seven Kittyhawks on a sweep from El Adem to Gazala. At this point Ops (codename 'Blackbird') vectored the formation on some enemy aircraft five miles north-east. Flight Lieutenant Westenra spotted some MC.200s and with his No. 2, Sergeant R. B. Evans, dived to attack them. Flight Lieutenant Westenra claimed to have downed one, which flew into the sea, but as he was about to attack again, 15 Ju 87s appeared out of cloud flying north-west as fast as they could go. Sergeant Evans saw them and attacked one on the extreme port side firing three bursts. The Ju 87 crashed into the sea. Flying Officer Knapik spotted two Bf 109s but because his windscreen then became oiled up he was unable to join in. In the face of lack of opposition, it seems as this formation was the remnants of the one that had been mauled by 450 and 3 RAAF Squadrons. According to the Italians, all of the Ju 87s (Ju 87R-2 WNr 5995 S1+GL of 3./StG 3 was 20% damaged with gunner Unteroffizier Gustav Riegel wounded) managed to escape despite the attention of 112 Squadron.
In the wake of this devastating combat, Generale Rino Corso Fougier, Regia Aeronautica Chief of Staff, praised the 150^o Gruppo pilots for their sacrifice which had allowed the Ju 87s to escape. But the Italians demanded better cooperation between their fighters and those flow by the Luftwaffe.

At the time of his death, Atti was credited with 2 shared probable biplane victories and a total of 2 shared victories.
