When Italy declared war on the Great Britain and France on 10 June 1940, Sergente Aldo Rosa served in the 91^a Squadriglia, 10^o Gruppo, 4^o Stormo C.T.

On 12 June, the 2^o Stormo’s fighters in North Africa were joined by those of the 10^o Gruppo (84^a, 90^a and 91^a Squadriglie) of the Gorizia based 4^o Stormo C.T.. The Gruppo was commanded by Tenente Colonnello Armando Piragino and started the war at Tobruk T2 with 27 CR.42s.
The 91^a Squadriglia C.T. was composed of the following pilots: Capitano Giuseppe D’Agostinis (CO), Tenente Enzo Martissa, Sottotenente Ruggero Caporali, Maresciallo Raffaele Chianese, Maresciallo Vittorio Romandini, Sergente Maggiore Leonardo Ferrulli, Sergente Maggiore Lorenzo Migliorato, Sergente Maggiore Natale Fiorito, Sergente Maggiore Elio Miotto, Sergente Rosa, Sergente Alessandro Bladelli, Sergente Guido Scozzoli and Sergente Luigi Ferrario. They had ten CR.42s on strength (including Piragino’s).

At 17:00 on 8 August, Maggiore Carlo Romagnoli (CO of the 10^o Gruppo) took off from El Adem T3 airfield with 15 other aircraft from the 9^o and 10^o Gruppi to patrol along the Egyptian border and to give indirect cover to five SM 79 bombers and a single reconnaissance Ro.37, which were out to patrol the same area. The five SM 79s were a formation from the 44^a Squadriglia, 35^o Gruppo, led by Capitano Giuseppe Pagliacci, which were out to bomb enemy vehicles and aircraft in the Bir El Chreigat area.
Participating pilots were Romagnoli, Capitano Giuseppe D’Agostinis (CO 91^a Squadriglia), Tenente Enzo Martissa (91^a Squadriglia), Sergente Rosa (91^a Squadriglia), Tenente Giovanni Guiducci (CO 90^a Squadriglia), Sergente Maggiore Angelo Savini (90^a Squadriglia), Capitano Luigi Monti (CO 84^aSquadriglia), Tenente Vittorio Pezzè (CO 73^a Squadriglia), Tenente Valerio De Campo (73^a Squadriglia), Sottotenente Carlo Battaglia (73^a Squadriglia), Sottotenente Alvaro Querci (73^a Squadriglia), Maresciallo Norino Renzi (73^a Squadriglia), Sergente Maggiore Enrico Dallari (73^a Squadriglia), Sergente Antonio Valle (73^a Squadriglia), Sergente Santo Gino (73^a Squadriglia) and Sergente Lido Poli (73^a Squadriglia).
Immediately after take-off, Romagnoli started to climb, keeping the sun in the back. At 2500 meters over Gabr Saleh (around 65 kilometres south-east of El Adem and 35 kilometres east of Bir El Gobi, well inside the Italian territory) when the Italian formation was still climbing, Tenente Pezzè saw two formations of Gloster Gladiators higher and, after giving the alarm to the gruppo commander, tried to attack the enemy fighters frontally and from below.
Then, completely unseen by Pezzè and the other Italian pilots a third formation of Glosters attacked the 73^a Squadriglia formation from above (the surviving Italian pilots estimated that each British formation was nine planes strong so, after the combat, they assessed that they fought against 27 enemy fighters for fifteen minutes).
The Gloster Gladiators were from 80 Squadron (‘C’ Flight had arrived at Sidi Barrani during the day, led by the commanding officer, Squadron Leader ‘Paddy’ Dunn). At 17:40, 14 Gladiators from the Squadron flew an offensive patrol in the neighbourhood of El Gobi since it had been reported by observers that large formations of CR.42s had been patrolling a triangle between El Adem, Sidi Omar and El Gobi fairly regularly twice a day at about 07:00 and 18:15 and it was decided to attempt to destroy a portion of this patrol. The mission had been suggested by Squadron Leader Dunn to the HQ as a reprisal and to re-establish “the moral superiority already gained previously by other Squadrons” after the gruelling engagement on 4 August. Tactics had been carefully discussed by Dunn and his Flight Commanders on the agreed assumption that if the engagement could be controlled for the initial two minutes, a decided advantage would be with the side in control. To do this, it was arranged (as it was expected to be seen as soon as, or even before being able to see the Italians) that a Sub-Flight of the formation (Sub-Flight one) should fly low (at 8,000 feet) and slightly in front to act as bait. These three Gladiators were flown (after that lots had been drawn) by Dunn (leader) (Gladiator K8009), Flying Officer Peter Wykeham-Barnes (K7916) and Pilot Officer 'Heimar' Stuckey (K8022). The rest of the formation, divided in three Sub-Flights of three fighters with an independent aircraft between the lower Sub-Flights, would be stepped at 10,000, 12,000 and 14,000 feet. The independent machine was that of Flight Sergeant Trevor Martin Vaughan (K7903), who attacked with Sub-Flight one. It seems that Pilot Officer Anthony Hugh Cholmeley flew a fourteenth Gladiator but that he was forced to turn back early, probably with engine problems.
Sub-Flight two included Flight Lieutenant Ralph Evers-Swindell (leader) (L8010), Flying Officer Wanklyn Flower (K8011) and Flying Officer P. T. Dowding (K7912). Sub-Flight three included Pilot Officer Harold Sykes (leader) (K8003), Sergeant Donald Gregory (K8051) and Flying Officer Sidney Linnard (K8017). Sub-Flight four at 14,000 feet included Flight Lieutenant 'Pat' Pattle (leader) (K7971), Flying Officer Greg Graham (L8008) and Flight Sergeant Sidney Richens (K7892). The plan was for Sub-Flight one to engage (or being engaged) by the Italians, do what it could until Sub-Flights two, three and four would be ordered to enter the combat on seeing the trend, the overall control being given to Sub-Flight four. All formations flew in a broad vic and it was the first time that the 80 Squadron operated at full operational strength.
Just after 18:00, the Squadron crossed the frontier south of Sidi Omar, and immediately changed course to head north towards Bir Taieb el Esem. At 18:25, as they were approaching Bir el Gobi, a formation of CR.42 flying in echelons was spotted by Flight Lieutenant Pattle. The Fiats were flying approximately parallel but reciprocal to the course of the British formation and they were at 2 o’clock and slightly (500 feet) below the lower Sub-Flight. With a careful turning on the right, ordered by radio, Pattle put the 80 Squadron’s formation behind the Italian one, up-sun and between it and its base at El Adem, then a full boast and throttle stern chase began to catch up with the fast cruising (in fact climbing) Italian fighters. Pilots in the lower Sub-Flights now began to see their opponents, dead ahead and lower. The ideal attack position! Squadron Leader Dunn counted 18 of them in four formations of seven, five, three and three; he was very close to the truth but later Sub-Flight four reported that an additional Italian formation of nine planes was present and it was incorrectly assessed that the Italians were 27, flying in nine sections of three aircraft. After an unobserved astern chase Sub-Flight one engaged the starboard flank of three aircraft and shot down all of them (they were probably part of the 73^a Squadriglia). Squadron Leader Dunn later reported:

“(…) I followed my first target down, who rolled over slowly on to his back with smoke coming out: Observed P/O. Stuckey’s (No. 3 on my left) quarry in much the same condition and gave him a burst of my own, then pulled up and across the rear of the formation of 18 that was beginning to peel-off.”

“(…) our C.O. led the first Flight and attacked the right hand enemy flight.
I was No. 3 of the C.O.’s Flight and managed to get in a long burst with full deflection as my opposite aircraft stall turned out of his formation. (later the C.O. said that he followed this aircraft down giving it bursts and saw it crash.
Immediately after I attacked No. 3 aircraft of the farthest flight and gave it a short burst before that flight broke up as well.”

“(…) A C.R.42 did a steep diving turn away from his formation and I was easily able to give him a full deflection shot for about 8 seconds, he continued in a dive with smoke issuing from him but as the formation of 18 was approaching around about me with advantage of number and height, it was impossible to pursue him. I claimed it definitely shot down and consider it to be one of the five observed on the ground by Sub 4 before entering. Then followed a long period of loose play in which numerous targets offered themselves.
At the same time large numbers of enemy aircraft attacked me, chiefly from straight ahead and beam but not driving home determinedly. In one of them I throttled back and stall turned on the attacker’s tail before he was quite past me, he then rolled on to his back and dived down in the second half of a loop. I followed and gave this aircraft what I thought was an effective burst with the result that he did not recover and continued down with bluish smoke issuing from him.
The other flights had by now entered and attacked their opponents, and the number of enemy aircraft thinned down. Two or three enemy aircraft were still about ; I pulled up steeply to avoid one in particular who was dangerously near to my tail, having chased me down in the dive from the port quarter. In the ensuing black-out I have little knowledge of what he did but at the top of what was the first half of something like a rocket loop, I found myself going in the opposite direction with the aircraft climbing rapidly past me on my left and below, he then appeared ahead of me and did a slow roll, unfortunately, I was too surprised and failed to get him in my sight, whereupon he half rolled and dived out; another stall turn brought me on his tail, but he did a rapid dive, turned to the left and streamed off like a homing rabbit - next stop El Adem.
I engaged one more enemy aircraft but my guns failed to fire (after 300 rounds approx.) I tried to clear them but was only able to get one more short burst. I left the fight, gained height at 12,000 feet and returned to witness a dog-fight between three aircraft two of which were Gladiators. I then set off home and picked up two other Gladiators.”

“I was then attacked from about 2 o’clock by the two flights that had already broken; I pulled away and down from them, and as I came up in a climbing turn saw a CR 42 following one of our Gladiators in a loop. While it was going up I gave it a long burst and saw it fall away and dive, the pilot jumped almost as soon as I attacked him. Another 42 came straight towards me while I was circling the parachute but I made a quick turn in the opposite direction and he passed just under my port wings. I then saw a 42 with a Gladiator on its’ tail and as I flew in on a beam attack the 42 flick rolled two or three times and continued doing so in a dive. I followed it all the way in a steep turn and dive giving a lot of short bursts and saw it crash. I was then at only about 3,000’ and when I had climbed to about 5,000’ joined in a dog-fight that ended when the 42 dived away and headed for Bir El Essem.”

“(…) I saw the leading formation attack the right hand formation of 9 E.A: so I put my sub flight into line astern expecting the E.A. to break up which they did as soon the first machine was shot down by No.2 of the leading formation. I led my sub flight into the centre formation of nine E.A. which by then were scattered all over the sky. I did a diving quarter attack on an E.A. up to about 50 feet, it turned over on its back and went down in a steep spiral. I was then attacked head on by another E.A. after this I looked down and saw the first one crash in flames. The pilot still in the cockpit. I managed to manoeuvre myself on to the tail of a third and after having given him a longish burst, saw him go down in the same way as the first, but was unable to follow him down as an explosive bullet took away one of my port flying wires and another burst on the starboard side of the instrument panel. I got in two more quick burst on two different E.A. but don’t think I did any damage. My engine then started to pour out smoke and soon afterwards cut out. I glided down in a series of steep turns and found no E.A. following. I looked round and saw nine a/c burning on the ground and one pilot coming down by parachute. I glided for about three miles and at about 200 feet the engine seized up I did not have time to inspect the engine so set the aircraft on fire (…).”

“(…) I picked out a CR 42 flying in left hand turn ahead of me. I dropped in behind and fired three long bursts at close range – I last saw the aircraft diving vertically downwards. At this moment another C.R 42 fired a burst into my machine damaging the engine. I got away from him and, as there were no more enemy machines in sight, made for home (…)”

“(…) Before we had reached them they had already been broken up before we joined amongst them.
I then saw a CR.42 coming towards me on port beam, it pulled its nose up and did a half roll to the left. I got my sights on to it, as it started to pull its nose up, and followed it round as it did the half roll, giving it a longish burst. It went into a spin, and went down a long way until I lost sight of it.
When I looked again there was an aircraft burning on the ground at approximately the position where the one went down, but I cannot say for certain whether it was the same as the one I saw go down.
I also saw at least four other aircraft burning on the ground, and three people descending by parachutes (…)”

“(…) I was leading sub 3 flight and putting the flight into echelon right turned on to their right flank. The enemy aircraft suddenly reeled of from their echelon formation probably owing to the fact that the leading flight had come into firing range and had opened fire. A general dog fight then commenced, I engaged a CR.42 which commenced a steep climbing turn, I commenced firing at the beginning of the climb and continued until I saw him fall and commence a flay spiral. I saw fragments or splinters falling from the centre section or the cockpit and saw the aircraft drop about 4-5000 feet and then engaged another which I followed in a steep turn firing all the time. This enemy aircraft went into a spin suddenly and saw one of our own aircraft follow it down. There were no more enemy aircraft in sight. During the action I saw several parachute open and several aircraft burning. I landed back on our aerodrome at 1915. One aircraft in my flight was forced to return just before the action because all its guns stopped.”

“(…) We were given R/T instructions by the top flight to enter the fight.
I slipped under my leader to the left and found myself in a mass of milling aircraft. I went to attack a CR.42 which was on a Gladiator’s tail when another CR.42 passed in front of me. I gave him deflection burst and got on to his tail – he pulled up in a loop. I followed him around giving him bursts and when he was upside down in the loop he baled out dropping past me, his parachute opening just below me. My range would be about 50 yards or less. I got on to another CR.42 and practically the same thing happened as before except that I did not get him and my engine cut as I was following him in the loop when I was in the vertical position. I saw the enemy aircraft diving past me but I was so close to him that he could not fire at me. I pushed my nose down and got my engine started and then saw a CR.42 diving down on me from vertically above but he did not hit me. I then saw a CR.42 practically head-on. I gave him a burst at very close range. The enemy aircraft turned over to the right on its back and went into a flat spin. I was at about 4,000 feet at this time. I watched the aircraft spin for about 1000 feet and then heard gunfire which I thought was from behind but there were no enemy aircraft within range of me. I then looked for the spinning aircraft but all I saw was an aircraft in flames on the ground beneath me. Another CR.42 dived past going very fast. I gave him a quick burst and saw some black smoke coming from him, but he kept straight on diving as fast as he could go towards Bir-el-Gobi. I did not follow him down. I then turned back towards where the fight had been but saw only one aircraft a Gladiator (P/O. Stuckey). We hung around a bit and then made for home. I caught up with F/Lt. Pattle and F/O. Graham and returned with them. I landed at 1910. I sustained no damage to self or aircraft except for one Fabric panel torn out.
I saw altogether 6 aircraft burning on ground and 4 parachutes dropping.”

“(…) I saw no’s 2 and 3 sections engage and before I brought my section into the fight I saw five crashed aircraft on the ground , three of which were in flames.
My own section then engaged those E.A. who were attempting to reach their own base and immediately became engaged in separate combats.
I engaged a CR 42 and, after a short skirmish, get into position immediately behind him. On firing two short bursts at about 50 yards range the E.A. fell into a spin and burst into flames on striking the ground. The pilot did not abandon his aircraft.
I then attacked 3 E.A. immediately below me. This action was indecisive as after a few minutes they broke away by diving vertically for the ground and pulling out at very low altitude.
Whilst searching for other E.A. I saw two more aircraft crash and burst into flames. Owing to the widespread area and the number of aircraft engaged it was impossible to confirm what types of aircraft were involved in these crashes or who shot them down.
The sky seemed clear of 42s’ although several Gladiators were still in the vicinity. I was about to turn for our base when a 42 attacked me from below. With the advantage of height I dived astern of him and after a short burst he spun into the ground into flames. As before the pilot didn’t abandon his aircraft. Flying Officer Graham confirms both my combats which ended decisively.
Seeing no further sign of Enemy Aircraft over the area, I turned towards our base. On my way home F/O Graham and P/O Linnard joined me in formation and my section landed at 19.10 hrs.”

“(…) set the aircraft on fire. First removing the water bottle and Very pistol. I walked for three hours away from the sun and then lay down to sleep. I slept till about 01.00 hours finding dense fog and myself wet through. I then dug a hole in some soft sand and buried my self. There I stayed till daylight. At about 06.30 next morning when the fog started to lift I started to walk into the sun until 15.00hrs. when I saw three armoured cars on the horizon. I fired three very light cartridges, the next thing I remember I was lying in the shade of the armoured car the crew told me I was about five miles from the wire.”

Maresciallo Norino Renzi was born on 22 January 1912 in Russi (Ravenna). He joined the Regia Aeronautica in 1929. He was assigned to the 4^o Stormo and received his military pilot’s license on 25 December 1930. He served with this unit until his death on 8 August 1940. Pre-war he was part of 4^o Stormo’s aerobatics group.

Martissa, who was initially missing, had force-landed his CR.42 with a hundred bullet holes in it, only 15 kilometres from El Adem. The wounded pilot claimed the individual destruction of two Gladiators (not confirmed in the official documents of his unit but later credited to him by post-war studies). In fact, Martissa was awarded with a third Medaglia d’argento al valor militare (in as many months) for this action. The official motivation of the award stated that he: ”shared in the destruction of five enemy planes together with other pilots”. He survived his ordeal by drinking dewdrops at dawn but after two days, he was becoming to expect the worst. One of the bullets, which had hit his aircraft, had pierced the griffin's head of Squadriglia's badge on the port wheel cover and Martissa wrote with a knife on the white background disc of the badge:

“You, little griffin, have been struck in the head. I would have suffered less if I had been likewise! I'm not mortally wounded, but I shall pass away, since I can't walk for 10-20 km to reach a track. And it will be by hunger and thirst.”

"We saw an aircraft in the desert. We approached and found Tenente Martissa under a wing, with a leg almost torn off by an explosive bullet from a British fighter. We rescued him. He told us that if we didn't come [to save him], he'd shoot himself in the head with his gun, because he was dying of thirst.
We rescued the pilot and left the aircraft."

MM4306, flown by Tenente Enzo Martissa on 8 August, when it later served with the 84^a Squadriglia of the 10^o Gruppo.

The Fiat CR.42 flown by Martissa (MM4306) was recovered and, in September 1940, assigned to the 84^a Squadriglia of the 10^o Gruppo as “84-4”.
Tenente Guiducci was also awarded with a Medaglia d’argento al Valor militare for this combat.
The Italians totally lost four aircraft while four more force-landed (it seems that all were later recovered). In return the Italian pilots claimed five Gladiators (three shared amongst the pilots of 10^o Gruppo and two shared by the surviving 73^a Squadriglia pilots) and two probables (the 90^a Squadriglia’s Diary reported six victories). Remembering the combat for the press, the Italian leader (obviously Maggiore Romagnoli) recalled that even if the attack of the Gladiators was possibly the deadliest he had ever seen, the reaction of his pilots was ”miraculously immediate”. He had just heard the first bullets whistling around him when his right wingman already was breaking with a zoom. Then he saw in his gunsight, the belly of a Gladiator and shot this down (most likely Flight Sergeant Vaughan, who had overshot during the first bounce).
For this exploit, 80 Squadron received the Press honours as well as written congratulations from the RAF HQ Middle East. Dunn and his pilots had exploited the strong points of the Gladiator over the CR.42 to the maximum extent especially the radio equipment, which had permitted a coordinated attack, being also crucial for obtaining the initial surprise and the Gladiators superior low altitude overall performances.
During the combat, the Gladiator demonstrated another interesting characteristic: a markedly superior horizontal manoeuvrability over its opponent. On regard of this point, it is interesting to report the impressions of Flying Officer Stuckey and Flying Officer Linnard.

“With trimming gear slightly back, found I could easily out manoeuvre a/c attacking from rear. No blacking out.”
“No difficulty in keeping astern of enemy aircraft. Enemy invariably looped for evasive action.”

On 23 November, Sergente Rosa and Sergente Alessandro Bladelli of the 91^a Squadriglia took off from T4 and claimed a damaged Wellington bomber.

On 12 December, Sottotenente Ruggero Caporali and Sergente Rosa from the 91^a Squadriglia’s alarm section at T4 claimed a damaged Blenheim.

Rosa ended the war with 3 shared biplane victories.
