Clizio Nioi was born on 15 July 1915.

On 1 October 1936, he was commissioned (in Servizio Permanente Effettivo).

In June 1940, Tenente Nioi served in the 80^a Squadriglia, 17^o Gruppo C.T., which was equipped with Fiat CR.32s.

In the afternoon on 23 June 1940, Palermo was bombed by four Glenn-Martin GM 167Fs from GB I/62 and three from GB II/62. The French bombers aimed at the harbour but many bombs fell in the city itself, killing 25 civilians and wounding 125 more.
The returning French crews didn’t report any presence of Italian fighters but one Glenn crashed before coming back to base and another crash-landed at Canrobert without losses among the crews, reportedly suffering mechanical breakdowns.
Another bombing of Palermo was made by five LeO 451s from GB II/11, which had taken off in the late afternoon from Youks-les-Bains (aircraft n^o200 commanded by Colonel Chopin, n^o 201 commanded by Lieutenant Calmel, n^o 213 commanded by Lieutenant Zimmermann, n^o 144 commanded by Lieutenant Drougue and n^o 3005 commanded by Capitaine Bouyer). In fact, only Zimmermann and Calmel hit the intended target from an altitude of 5000 metres; Chopin returned early because of a breakdown, Bouyer attacked Marsala, while nothing was heard of Drougue’s aircraft that, forced to take off late, became immediately separated. In Fact it seems that LeO 451 n^o 144 returned at night, probably short of fuel and trying to force-land on a beach near Cap Bon it exploded, killing the crew.
From the Italian records we know that at 18:25, seven “enemy bombers” were discovered over Palermo at approximately 4000 metres, they attacked the harbour diving with the engines shut-down and achieved complete surprise. The CR.32s of the 17^o Gruppo tried in vain to intercept because of the late discovery and the height of their opponents. In the meantime, alarm was given also to the CR.42s of the 157^o Gruppo and the CR.32s of the 80^a Squadriglia, 17^o Gruppo, then detached to Trapani, in the hope of catching the raiders during the return leg of their mission. The fighters from the 157^o Gruppo scrambled at around 18:40 and returned one hour later without having seen any enemy while, flying north, two CR.32s of the 80^a Squadriglia, piloted by Tenente Nioi and Tenente De Tecini discovered an alone aircraft off Capo Gallo (slightly west of Palermo’s harbour). The aircraft was identified as a “Potez 63” and attacked by Nioi, who could benefit of a slight height advantage over his target. Nioi hit it, observing the French raider that nose dived engulfed in a thick cloud of smoke. Later ground observers reported that the aircraft had fallen into the sea and Nioi was credited with his first aerial victory. Finally, at 19:30, a last attack on Mazara del Vallo (an harbour very close to Marsala) was reported.
It seems probable that one of the French bombers, possibly the lone LeO 451 of Lieutenant Drogue was the machine attacked by Nioi.

He was promoted to Capitano on 6 February 1941.

Later in the war, Capitano Nioi served as commander of the 80^a Squadriglia.

At 15:55 on 12 December 1941, eleven MC.202 of the 17^o Gruppo (six from the 71^a Squadriglia and five from the 80^a Squadriglia), led by Capitano Aldo Felici, took off for troop protection between Gazala and Derna. At 16:00, at the height of 1500m., almost immediately after take-off, they clashed with an enemy formation estimated 30 Curtiss P-40 and Hurricanes strong, apparently directed to attack the landing ground of Martuba.
The Italians claimed no less than eight planes (one each by Capitano Nioi, Tenente Glauco Vatta, Sottotenente Renato Bagnoli, Maresciallo Marcello Lui, Maresciallo Pio Marsilli, Sergente Maggiore Mario Host, Sergente Maggiore Remo Broilo and Sergente Egidio Buogo) and two probables. Three MC.202 were hit in the cooling systems of which Capitano Nioi landed OK, Tenente Vatta crash-landed on base and Tenente Conti belly-landed and was slightly wounded. A fourth Macchi was slightly damaged. The formation landed at 16:35 (or alternatively 16:55) and the Italian pilots had expended 3680 rounds of ammunition.
Three MC.202 of the 81^a Squadriglia (6^o Gruppo), led by Tenente Giorgio Falchi, scrambled at 16:10. Once reached the height of 1000m, at 16:20, they discovered ten Hurricanes strafing the German sector of Martuba. The Macchis jumped the enemies and Tenente Falchi damaged two of them using 80 rounds of ammunition and in turn he was hit by three rounds. The Italian fighters landed at 16:50.
Between 16:00 and 16:10, III/JG 53 claimed six Hurricanes and a P-40. These were claimed by Oberfeldwebel Hermann Neuhoff of 7./JG 53 (Hurricane at 16:00 and P-40 at 16:10), Unteroffizier Erich Schmidt of 7./JG 53 (Hurricane at 16:00), Leutnant Siegmund Hosnedl of 7./JG 53 (Hurricane at 16:00), Oberfeldwebel Werner Stumpf of 9./JG 53 (2 Hurricanes at 16:03) and Leutnant Wolf Schaller of 9./JG 53 (Hurricane at 16:10). On the Commonwealth side, it appears that at 15:15, nine Tomahawks of 4 SAAF and others of 2 SAAF Squadron, had taken off as top and close cover to a bomber formation targeting the Derna road. The bombers were probably six Blenheims of the 14 Squadron, which reported the attack to the escort with heavy losses of the latter. The South Africans of 4 SAAF Squadron were engaged for 30 minutes with twelve enemy fighters and three Bf 109s were claimed (Captain Andrew Bosman (2) and Lieutenant Douglas Golding) plus two damaged by Bosman, while Lieutenant Lewis Otto Beatty Player (SAAF no. 102848V) was lost (according to some sources, the Bf 109 that shot down Player was then shot down by Golding). 4 SAAF Squadron landed again at 16:55.
2 SAAF Squadron reported only that they was jumped by Bf 109s, loosing Lieutenant James Rattray Verster and Captain Piet Robbertse (both PoWs). 2 SAAF Squadrons landed back at 15:55. According to some sources, the South Africans losses were all to Bf 109s.
At 15:30, ten Tomahawks of 3 RAAF Squadron and eight of 112 Squadron took off to attack Derna. At 16:00, above Tmimi, 112 Squadron was flying at an altitude of 4000 feet when at three o’clock, between 9000 and 15000 feet, was seen a number of enemy aircraft already engaged with a friendly formation. The base layer of clouds was at 5000 feet. Height was gained up to 10000 feet toward the sun in order to carry out the attack from an ideal position. Thus, it may be assumed that the action of South African was merged with the latter, in line with the estimate number of opponents made by the pilots of the 17^o Gruppo. The pilots from 112 Squadron reported:
Pilot Officer J. P. Bartle (Tomahawk AN372/Q):

“Fired long burst at 109 F and saw smoke or oil or both pour from his engine. He seemed to go in a long dive. Saw what appeared to be glass house break away from M.202 after burst. Two 109 Fs chased me down to 500 feet making alternate quarter attacks. I kept turning into each as he made his attack. E/A opened fire at very long rang, E/A broke away (possibly ran out of ammo).
I claim a 109 F probably destroyed and a M.202 damaged.”

“Engaged one M.202 with PO Humphreys and had a violent dogfight, no hits observed. Then two others attacked me, I turned inside one and saw a flash inside his fuselage and he dived away. The other meanwhile had been engaged by another Tomahawk.
Claim one 202 damaged, self no damage. Macchi dived vertically and the climbed straight up into sun. Very hard to hold the climb.”

“Two enemy aircrafts attacked No.2 Red Section by diving from above. These two a/c followed line astern. I turned in, fired on both and followed one down. The first - a 109 F - appeared to be hit near the cockpit as a flash appeared. When about 4000’ lower was still on his back. After following and loosing a 109 I climbed to 12000 feet and was jumped by a 109 E (a Macchi?) which chased me down to cloud cover.”

“While on offensive fighter sweep over Tmini area 1300 ft (sic) E/A were reported 9 o’clock below and climbing. During the formation turn two aircraft collided. One of these turned in the direction of the base and dived for a cloud layer at 3000 ft. I turned and dived to follow him. While catching Tomahawk to escort to base ME 110 was sighted above flying towards me. Cloud base was 3000 ft. and E/A was just beneath. Pulling around into his tail from beneath flames came from wing root and fuselage after two bursts. I then lost sight of the a/c.”

On 28 March 1942, three MC.202s of the 6^o Gruppo (one from the 79^a Squadriglia and two from the 81^a Squadriglia) led by Tenente Palazzeschi, scrambled at 13:35 (returning at 14:30) to intercept a formation of enemy bombers and fighters over the airfield. (this action is recorded by the Gruppo’s Diary only)
Between 13:35 and 13:40, twelve MC.202s from the 17^o Gruppo (three from the 71^a Squadriglia, four from the 72^a Squadriglia and five from the 80^a Squadriglia), led by Capitano Nioi, took off after the same enemy formation.
West of Tobruk, only Tenente Bruno Ganda of the 81^a Squadriglia was able to engage the enemy and claimed a P-40 shot down with the use of 250 rounds of ammunition.
Five pilots of the 17^o Gruppo engaged, claiming a P-40 by Capitano Nioi who also damaged a bomber west of Tobruk and three P-40s damaged by three other pilots (two of them subsequently upgraded to probables with the use of 1050 rounds of ammunition). The pilots of the 17^o Gruppo believed that the enemy bomber formation, escorted by around 30 P-40s, returned individually. The enemy aircraft were a formation of nine Bostons from 12 SAAF Squadron, escorted by nine Kittyhawks of 94 Squadron (take off 12:40 and landing 14:15-14:35) as middle cover, twelve Kittyhawks of 450 Squadron as top cover and finally a close cover of Kittyhawks of 2 SAAF Squadron. Martuba West was bombed from 11,000 feet; 35 bombs hit the target area and some of them exploded near planes dispersed on ground. A storage was set on fire. AA was intense and precise; two Bostons were heavily damaged and two more were slightly damaged while Observer Lieutenant Ian Ross was killed.
Immediately after the bomb release the formation was attacked by at least twelve Bf 109s, 450 Squadron suffered the loss of Sergeant Halliday (AK695/G); the pilot made a wheels-up landing in no man’s land wounded and was later recovered by the Army, 94 Squadron lost Pilot Officer 22-year-old Pilot Officer James Aitken Crosbie (RAF no. 101493), who was wounded, his fighter was later recovered and classified Cat. II. During the combat, Flight Sergeant Eddie Edwards (FZ-V) saw frantic activity above him. He watched as the Bf 109s dived down and then pulled upward again. While most stayed high, some of them continued their dive into the path of 94 Squadron. As two passed in front of him, he fired several bursts of ammunition. The first Bf 109 made a steep climb and the other rolled over and headed west. He thought he might have hit the second Bf 109 but he made no claims, as he was not sure. 450 Squadron suffered two more fighters heavily damaged (Cat.II) plus a third obliged to force-land reportedly due to lack of fuel. (Cat II) while Squadron Leader Gordon Steege (AK692/C) and Sergeant Shillabeer (AK799/R) claimed a Bf 109 probable each; that of Steege was subsequently upgraded to confirmed. Sergeant Ian Nursey (AK668/H) claimed a probable MC.202 and Pilot Officer Kelsall (AK895/K) a damaged Bf 109. The pilots of 450 Squadron recorded being engaged from their arrival over the target until the return to base.
One of the two damaged machine was that of Sergeant Quirk, who returned and landed without flaps at 150 mph, with a big chunk of the left wing close to the flap lacking. Quirk was probably hit by a cannon shell from a Bf 109.
Strangely, 2 SAAF Squadron didn’t report any action even if the Macchis had reached the bombers. Feldwebel Günther Steinhausen of 1./JG 27 claimed a P-40 at 13:40 near Tmimi (possibly Halliday), so at least one victory was obtained by the 1^o Stormo’s pilots who were most likely the main responsible for the heavy opposition experienced that day by the Commonwealth units. At the end of the day 3 Wing ORB summed up: “A raid on Martuba is no longer a profitable transaction”.
The wounded Pilot Officer Crosbie was later reported to be with a field ambulance, and was said to be only slightly wounded, but on 5 April the news was received that he had died on the 4th.

On 3 April, both Gruppi of 1^o Stormo scrambled to intercept a formation of bombers escorted by fighters heading for Derna.
Nine MC.202s of the 6^o Gruppo (seven from the 79^a Squadriglia, one of the 81^a Squadriglia and one of the 88^a Squadriglia) took off at 10:15 led by Capitano Domenico Camarda (CO of the 79^a Squadriglia). Flying at the height of 4000 meters over Gazala, four Macchis reached the enemy formation and engaged the escort (whose planes were identified as P-46s – but obviously Kittyhawks. Three of them were claimed damaged, one was claimed shot down by Tenente Angelo Cattaneo (79^a Squadriglia) who saw his opponent landing hurriedly in Gazala and another was claimed probably shot down. Maresciallo Bertinelli (79^a Squadriglia) was shot down in flames the Bomba area and lost his life. The other pilots landed back between 10:50 and 11:15 after having used 1345 rounds of ammunition.
Eight MC.202s of the 17^o Gruppo (three from the 71^a Squadriglia and five of the 80^a Squadriglia) led by Capitano Nioi, took off at 10:30. Five of them succeeded in engaging twelve P-40s claiming four shot down confirmed and one probable. The confirmed victories went to Capitano Nioi, (who also claimed the probable), Maresciallo Castellani (80^a Squadriglia), Sergente Maggiore Mario Host (80^a Squadriglia) and Sergente Maggiore Alvise Andrich (80^a Squadriglia). A sixth plane was damaged. The Italian pilots were back at 11:20 and they had expended 1690 rounds of ammunition.
With this victory Capitano Nioi qualified as an ace, as the first pilot of the Stormo to reach this status during the conflict.
Twelve Bostons of 12 SAAF Squadron were in action over Derna escorted by four Squadrons. 2 SAAF and 4 SAAF Squadrons, each with six Tomahawks formed the close cover, 94 Squadron acted as top cover (they had taken off between 10:30 and 10:45 and returned between 11:50 and 12:10); and finally eight Kittyhawks of 260 Squadron, which had taken off at 10:30, as an extra top cover. Additionally twelve Kittyhawks of 450 Squadron had taken off at 10:40 to cover the returning bombers. They were divided in two formations, one at 19000 feet and a second at 17500 feet. They directed over Bu El Bergasi, Gazala then stationed over Menelao bay waiting for the bombers. Finally, ten Hurricane IIBs of 274 Squadron had taken off at 10:50 for a diversionary sweep over Gazala, two of them had to return early for engine problems.
4 SAAF Squadron recorded that the bombing attack, performed on a east-west course from the height of 14000 feet was quite accurate. 45 well dispersed enemy aircraft were counted on the airfield. In particular in the northeastern corner of Derna were more than 20 enemy aircraft dispersed and the bombs were seen to fall south of them.
During the attack, eight Bf 109s were seen to take off from the southwestern corner of Derna, apparently alerted by heliograph signals from Martuba. 2 SAAF Squadron also noted the take off of enemy fighters from Martuba but the two South African units weren’t engaged.
Immediately after the bombing attack, 94 Squadron was engaged by three Bf 109 of I/JG27, and Pilot Officer Usher possibly shot down the Messerschmitt of Leutnant Wildau, while the Squadron didn’t suffer any loss.
Subsequently, over Menelao bay, five miles north-west of Bomba, 260 Squadron claimed two Bf 109s (one by Flight Sergeant Thomas Hindle and one shared between Squadron Leader Osgood Hanbury (AK867) and Sergeant Carlisle). Then Flight Sergeant Hindle engaged a MC.202, 30 miles south south-west of Gazala and claimed it probably shot down. The 6^o Gruppo was possibly involved in this combat together with some Bf 109s, with the loss of Maresciallo Bertinelli while the Germans lost Leutnant Rainer who was obliged to force-land. After this, close to Gazala, Hindle was attacked by two Macchi MC.202s (probably from the 6^o Gruppo); the first one, after the attack headed west while the second engaged in a inconclusive dogfight. Finally, over El Adem, Hindle was attacked by two Bf 109, being able to shot at one of them without claiming any damage.
The fighters of 260 Squadron landed at 12:15 without reporting any damage at all even if the ORB of 4 SAAF Squadron noted that a Kittyhawk of 260 Squadron was heavily shot up but succeeded in landing back at base.
In the Gazala area, 94 Squadron lost 19-year-old Pilot Officer Richard Warwick Martin Moon (RAF no. 106647), who failed to return and the fighter of Sergeant Musker, who was wounded, while Sergeant Ray Matthews (AK735) was obliged to force-land near Gazala due to engine problems in a situation that matched that described by Tenente Cattaneo, a fact that suggest the presence of the 6^o Gruppo in the combat.
In the meantime, 450 Squadron discovered the bombers that were coming back to base and saw higher two Bf 109s that failed to intervene. South of Gazala the Squadron headed south towards a combat already ongoing (possibly the already described action involving 260 and 94 Squadrons) and two of its pilots engaged two MC.202s and one was claimed damaged by Sergeant Ian Nursey (AK606/OK-B).
Between El Adem and Tobruk, 450 Squadron’s CO, Squadron Leader Gordon Steege (AK717/V), discovered three MC.202s flying lower and led his unit to attack. Two of the Italian fighters were claimed damaged (one claimed by Steege). All the fighters of 450 Squadron returned unscathed even if one of them had been forced to return early with engine problems.
Then it was the turn of 274 Squadron, which engaged Bf 109s and MC.202s, claiming two probable Bf 109s by Pilot Officer Hunter and Sergeant Garwood and a Macchi damaged, but suffering the loss of the plane of Sergeant Howell, who was wounded but was saved.
The diary of Sergeant William Marsh who was flying Hurricane IIB BD820/D recorded only Macchis (possibly the formation of the 17^o Gruppo):

“1 Macchi 202 damage: engaged by 6+, one of which turned on to Sgt. Presse, my No. 1. Pukka dog-fight for ten minutes, 202 looping and rolling, got in snap shots at bottom of loops. Broke off combat when a second 202 appeared – my ammo finished too. Sgt. “Tiny” Howell shot down.”

On 6 April, the 6^o and 17^o Gruppi scrambled to intercept a raid of bombers escorted by fighters over Derna. The 6^o Gruppo scrambled with six fighters (three from the 79^a Squadriglia, two from the 81^a Squadriglia and one from the 88^o Squadriglia), which took off at 08:10 and returned between 09:10 and 09:15 while eight fighters from the 17^o Gruppo (one from the 71^a Squadriglia and seven from the 80^a Squadriglia) scrambled at 08:20 and landed back at 09:40.
The fighters from the 6^o Gruppo had barely taken off when the Commonwealth formation composed of twelve Bostons escorted by many fighters stepped at different heights released its bomb-load on Derna El Ftehja. Only Capitano Domenico Camarda (79^a Squadriglia) and Capitano Dante Ocarso (88^a Squadriglia) were able to reach the raiders at the height of 4000m. Capitano Ocarso reported that he reached the enemy formation over Gazala and attacked even if flying at inferior height and heavily outnumbered. He claimed a P-40 shot down and three damaged with the use of 730 rounds of ammunition, then he flew back to base without suffering any damage. Capitano Camarda claimed a damaged Hurricane with the use of 80 rounds.
Part of the 17^o Gruppo formation was able to reach the Commonwealth Squadrons after a long chase at around 09:15 at the height of 6000 metres. They were Capitano Nioi, Sergente Maggiore Alvise Andrich, Tenente Emilio Marchi and Tenente Renato Talamini. One P-40 each was credited to Capitano Nioi and Sergente Maggiore Andrich (80^a Squadriglia) while four more P-40s were damaged. Tenente Saladini force landed with engine trouble. The pilots of 17^o Gruppo had expended 1330 rounds.
The raid had been performed by the usual formation of twelve Bostons escorted by nine Kittyhawks of 94 Squadron (take off 08:20 and landing 09:50), Tomahawks IIb of 2 SAAF and 4 SAAF Squadrons and finally by five Kittyhawk of 260 Squadron (take off 08:35 and landing 10:10) as extra top cover. 4 SAAF Squadron joined the formation over El Adem. In the meantime, twelve Hurricanes of 274 Squadron (take off 08:55) made a delousing sweep over Gazala together with 33 Squadron.
94 Squadron was attacked during the return journey by Bf 109s and MC.202s (possibly the two machines of the 6^o Gruppo). At 09:20, Pilot Officer Usher and his wingman Sergeant Wallace discovered two Bf 109s and a Macchi over Martuba, while the bombers had just banked to return to base. Axis fighters should had just taken off, in fact they were 2000 feet under the 94 Squadron that was flying at 18000 feet. Pilot Officer Usher recorded in his CFR:

“As the bombers turned to the left after dropping their bombs, I saw three E/A below on my left. I attacked straggling 109, which tried to avoid me by turning. I saw my bullets go into his left wing. This attack developed into dead astern and by time I was 30 yards behind him most of my guns had stopped firing. I noticed holes in his left wing and broke away in a dive to get under the bombers.
Ammunition expended 1100 rounds.”

On 10 June, the 6^o Gruppo and the 17^o Gruppo jointly carried out a free sweep in the Bir Hakeim - Bir el Harmat area.
Between 14:50 and 14:55 six planes of the 6^o Gruppo drawn two each from the three Squadriglie had taken off under Capitano Domenico Camarda (79^a Squadriglia). At 15:00 they were followed by six planes of the 17^o Gruppo led by Capitano Nioi (80^a Squadriglia).
At 15:20, while flying at 5000 metres east of Bir Hakeim, a mixed formation of Hurricanes and P-40s was attacked. According with the 6^o Gruppo the enemies were around twenty while according with the 17^o Gruppo they were fifteen.
Six P-40s were claimed by the pilots of the 6^o Gruppo with 14 more damaged with the use of 2625 rounds of ammunition. Credit for the victories went to Capitano Camarda, Sergente Amedeo Benati (79^a Squadriglia), Sergente Maggiore Luigi Morosi (81^a Squadriglia), Maresciallo GianLino Baschirotto (two) (88^a Squadriglia) and Sergente Maggiore Anano Borreo (88^a Squadriglia).
Only four pilots of the 17^o Gruppo were able to join the combat. Sergente Maggiore Alvise Andrich (80^a Squadriglia) claimed a P-40, while a second was shared among Capitano Nioi, Tenente Ghiglia (80^a Squadriglia) and Sergente Maggiore Aldo Bersani (80^a Squadriglia); the four pilots had used 1760 rounds of ammunition.
The running fight lasted for a long time and went as far as El Adem. All the Italian pilots came back unscathed, the 6^o Gruppo between 16:00 and 16:05 while the 17^o Gruppo returned at 16:20.
It seems that the 1^o Stormo’s pilots had met a mixed formation of 73 Squadron and 213 Squadron. At 15:40, some Hurricane IIC of 73 Squadron, (possibly twelve), covered by eleven Hurricane II from 213 Squadron (that had taken off at 15:35), had taken off for a protective cruise over Bir Hakeim. South-west of El Adem at a height between 8000 and 11000 feet, the pilots of 73 Squadron reported being jumped by a formation of twelve Bf 109 and Macchi C.202 despite the escort of 213 Squadron. They claimed to have probably shot down one of the attackers (Sergeant Ronald Baker in Hurricane BN402 claimed a probable Bf 109F) and to have damaged two more (Squadron Leader Derek Ward in Hurricane BN131/P and Sergeant Henry) while losing the plane of Sergeant Alan Stuart Wilson, who jumped with parachute but without suffering any additional loss. 213 Squadron reported being attacked by four Bf 109s (possibly the Macchis of the 17^o Gruppo) and claimed one of them damaged and two probably damaged. One Hurricane was slightly damaged. 73 Squadron was back at 17:00.
33 Squadron, was up with 274 Squadron (take-off at 17:15) in the same area (Knightbridge), and recorded being attacked by six Bf 109s and MC.202s that heavily damaged a Hurricane (Sergeant Menzies whose plane was Cat.II) during a dogfight. Despite the identification of Italian fighters and the “dogfight” it seems unlikely that they had met 1^o Stormo because of the timing. 274 Squadron recorded additionally a high cover of four Spitfires of 145 Squadron flying at 19000 feet while as usual the take-off time for 33 Squadron is unrecorded.
It is worth to note that only 33 Squadron recorded the combat while nothing happened for 274 Squadron.

In 1943, Nioi still served in the 17^o Gruppo Autonomo.

Nioi ended the war with 1 biplane victory and a total of 7.
During the war, he was decorated with three Medaglie d'argento al valor militare.
