Sergente Maggiore Bruno Bortoletti

When Italy declared war on the Great Britain and France on 10 June 1940, Sergente Bruno Bortoletti served in the 90a Squadriglia, 10o Gruppo, 4o Stormo C.T.

On 12 June, the 2o Stormo’s fighters in North Africa were joined by those of the 10o Gruppo (84a, 90a and 91a Squadriglie) of the Gorizia based 4o Stormo C.T.. The Gruppo was commanded by Tenente Colonnello Armando Piragino and started the war at Tobruk T2 with 27 CR.42s.
The 90a Squadriglia was composed of the following pilots: Capitano Renzo Maggini (CO), Tenente Franco Lucchini, Tenente Giovanni Guiducci, Sottotenente Neri De Benedetti, Sottotenente Alessandro Rusconi, Maresciallo Omero Alesi, Sergente Maggiore Angelo Savini, Sergente Amleto Monterumici, Sergente Silvio Crociati, Sergente Giovanni Battista Ceoletta, Sergente Alfredo Sclavo, Sergente Bortoletti, Sergente Paolo Guillet and Sergente Ernesto Keller. The last three pilots didn’t take part in the move to T2. The Squadriglia had nine Fiat CR.42s on strength.

On 1 August, Tenente Franco Lucchini, Sergente Alfredo Sclavo and Sergente Bortoletti, all of the 90a Squadriglia went to Tmini M2 airfield (around 100km west of Tobruk near the Gulf of Bomba) on alarm duty.

On 11 September, the 9o and 10o Gruppo were still employed in standing patrols over the troops. During the second patrol of the day, at 17:45 in the Sidi Omar – Bardia area, a Blenheim was discovered at 6000 metres.
The Italian formation was escorting three CR.32s and was led by Maggiore Carlo Romagnoli. It was composed of seven CR.42s from the 84a Squadriglia (Capitano Luigi Monti, Capitano Vincenzo Vanni, Tenente Giuseppe Aurili, Sottotenente Paolo Berti, Sergente Roberto Steppi, Sergente Narciso Pillepich and Sergente Domenico Santonocito), five CR.42s from the 91a Squadriglia (Capitano Giuseppe D’Agostinis, Sottotenente Ruggero Caporali, Sergente Maggiore Leonardo Ferrulli, Sergente Elio Miotto and Sergente Alessandro Bladelli) and six CR.42s from the 90a Squadriglia (Tenente Giovanni Guiducci, Tenente Franco Lucchini, Sottotenente Neri De Benedetti, Maresciallo Omero Alesi, Sergente Maggiore Angelo Savini and Sergente Bortoletti).
Capitano Vanni, Tenente Aurili and Sergente Steppi attacked first, followed by other pilots of the formation. During the combat Vanni’s aircraft was hit by return fire and with the compressed air piping pierced, he was forced to turn back. His wingmen continued the pursuit and claimed the Blenheim shot down.
The bomber however was assigned as a shared to all the 10o Gruppo pilots presents (even if , for example, it is known that 90a Squadriglia pilots totally used only 140 rounds of ammunition so possibly only one of them was able to use his guns).
This claim can’t be verified with RAF sources but it is possible that it was a Blenheim from 113 Squadron since this unit’s ORB is lacking.

On 14 September, the 4o Stormo continued to protect the ground forces. A mixed formation of 23 CR.42s from the 9o Gruppo commanded by Maggiore Ernesto Botto with 15 CR.42s from the 10o Gruppo as high cover, took off at 10:25. At 11:00, over Sollum some 10o Gruppo pilots discovered a formation of four Bristol Blenheims. They attacked and claimed one shot down in flames. The bomber was credited as a shared to the whole formation from the 10o Gruppo (Tenente Giovanni Guiducci, Sottotenente Luigi Prati, Tenente Franco Lucchini and Sergente Bortoletti of the 90a Squadriglia and Maggiore Carlo Romagnoli, Capitano Giuseppe D’Agostinis, Sottotenente Andrea Dalla Pasqua, Sottotenente Ruggero Caporali, Sottotenente Carlo Albertini and Sergente Maggiore Leonardo Ferrulli of the 91a Squadriglia and Capitano Luigi Monti, Capitano Vincenzo Vanni, Tenente Giuseppe Aurili, Tenente Paolo Berti and Sergente Domenico Santonocito of the 84a Squadriglia).
Sottotenente Albertini later told that that the Blenheim had been left behind by its squadron and he fired at it all the rounds he had, but he could not destroy it. At the beginning, the bomber returned fire, but after being hit several times, they stopped and no sign of life could be noticed. He followed the bomber for a while, once finished his rounds, but nothing happened, and the Blenheim continued on the same route.
This clam can’t be verified with RAF records. The only known British actions for the day were a couple of afternoon bomber raids. Four Blenheims of 55 Squadron with others from 211 Squadron were ordered to attack Italian troops in the Sollum area in the first afternoon. The 55 Squadron quartet came back at 16:45 without suffering losses. Its pilots reported slight and ineffective AA fire and the presence of Italian fighters (but no interception occurred). Eight machines of 211 Squadron led by Gordon-Finalyson also attacked, claiming many hits in the target area. However, no Italian fighters were seen and all the bombers were back at around 17:10.

On 16 December and in a last futile attempt to help the garrison at Sidi Omar, six SM 79s from the 29o Gruppo led by Colonnello Mario Aramu took off from Derna at 14:40 for a low-level strike. The formation of what was to become one of the most famous ill-fated missions of the Regia Aeronautica was as follows:

The Savoias were intercepted by a reportedly 20 Hurricanes at 1200 meters altitude, in sight of their intended target, after an hour of flight. The two vics of SM 79s tightened up their formation, trying to fight back. The first to go down was the plane of Grandjacquet. The SM 79 of Tenente Timolati then closed formation with the leading vic only to witness the demise of Colonnello Aramu’s bomber and shortly after that Sottotenente Tonachella’s. The three surviving SM 79s fled towards the sea with Hurricanes on their tail and suffered the last damage, which caused the death of some crewmembers before the Hurricanes disengaged (due to the intervention of some fighters of the 10o Gruppo). The SM 79 then released their bomb-load into the open sea and returned to Derna where at 16:30 Sottotenente Martemucci’s bomber broke its landing gear and crash-landed, damaging the wing. Timolati reported that Aramu’s SM 79, the dorsal gunner was immediately killed and his place was taken by Capitano Girolami, who was killed soon after when a well placed burst hit the Savoia’s cockpit killing him and causing the demise of the aircraft. The returning crews claimed five Hurricanes in return.
Sottotenente Tonachella and Tenente Padrone were the only survivors of the missing SM 79s. They both escaped with parachute and were captured by British patrols. Padrone, back in Italy after the war left a description of the events:

“the morning of 16 December 1940 three SM79 planes led by Colonello Aramu (I don’t remember the left hand wingman but I was the right hand) attacked with small calibre bombs and strafed from very low level British mechanized vehicles south-west of Bardia.(…). Back at base, Aramu knew that another mission was to be flown in the afternoon, to attack armoured concentrations around Sollum. Two section of three planes in line astern one 500 metres from the other were to be employed. The overall formation had to be commanded by Tenente Colonnello Gradjacquet leading the first section while Capitano Girolami had to lead the second section. Aramu decided to take part also in this action so he took the lead of the first section with Girolami acting as a bomb aimer and Grandjacquet took the lead of the second section. The two sections could attack independently because they all had a bomb aimer. The formation took off at 15.00 and when over Tobruk waited without avail for some minutes for the escort fighters, then directed toward the target flying deep inside the desert to avoid interception. When in the area between Sidi Omar and Capuzzo, when I was preparing to turn on the intercom with the bomb aimer I heard the guns of our plane shooting so I understood that we were under attack. The enemy planes most likely arrived from astern because in front of us I could see only the section of Aramu. Immediately after a burst of fire hit our plane silencing the dorsal gun and also hitting the instrument panel. I tried to assess the damage suffered but saw Grandjacquet busy in flying the plane and the wingmen at their place. Then a fire started in the rudder pedals area. I tried to give the alarm shouting but nobody moved, neither Tenente Colonnello Grandjacquet that didn’t move even after I shook him (probably he was already dead and kept in position by the seat belts). Therefore, unable to take command of the plane because of the fire and fearing that the flames could ignite my clothes I open the emergency door on the roof and jumped with parachute. I immediately saw my plane falling on ground engulfed by flames, not so far two other planes were falling in flames. Once on ground I noticed two other parachutes (…). I walked in a north-westerly direction for two days and then I was captured by a British patrol. Two month later in Cairo a RAF Officer asked me about the fate of Colonnello Aramu, so I understood what happened to him, Capitano Girolami and their crew (…).
The loss of these three COs was a terrible blow for the bomber force of Va Squadra and in particular the loss of the forty-years-old Aramu. He was a beloved leader, previously part of the “Atlantici” having crossed the northern Atlantic under Italo Balbo in 1933. He had then fought during the Spanish Civil War where on 21 May 1937 he had disabled the Republican Battleship Jaime Io in Almeria harbour with a well-aimed salvo of bombs from 4000 metres. The three officers were immediately awarded posthumous Medaglie d’Oro al valor militare but in fact such was the severity of the loss suffered that 29o Gruppo was immediately ordered back to Italy.
Colonnello Aramu was not alone over this area because three SM 79s of 15o Stormo were up under Tenente Medun. (take-off from Z1 at 14:55 and landing at 16:35) and at 14:45 nine SM 79s of the 41o Stormo under Tenente Colonnello Draghelli and Capitano Ammannato took off from M2 for a low-level strike (900 metres). These bombers were attacked by RAF fighters for a long time but were effectively protected by CR.42s and landed back at 16:50 without suffering damage.
The CR.42s were 17 fighters from the 10o Gruppo, which had taken off from T4 at 14:40. At the head of the formation was as usual Maggiore Carlo Romagnoli, with him were four fighters from the 91a Squadriglia (Capitano Vincenzo Vanni, Sergente Maggiore Leonardo Ferrulli, Sergente Maggiore Lorenzo Migliorato and Sergente Maggiore Natale Fiorito), three from the 84a Squadriglia (Capitano Luigi Monti, Sottotenente Paolo Berti and Sottotenente Luigi Prati) and nine from the 90a Squadriglia (Tenente Giovanni Guiducci, Tenente Franco Lucchini, Sottotenente Neri De Benedetti, Sergente Maggiore Angelo Savini, Sergente Alfredo Sclavo, Sergente Luigi Contarini, Sergente Bortoletti, Sergente Luigi Bagato and Sergente Giovanni Battista Ceoletta). Capitano Monti and Maggiore Romagnoli didn’t record any action but the 90a Squadriglia formation was heavily engaged. Firstly four Hurricanes tried to attack the SM 79 formation but were prevented, then two more Hurricanes that had just successfully attacked another unescorted SM 79 formation were engaged and one of them was reputed probably shot down (later upgraded to confirmed in the unit’s documents) and assigned as shared to the whole formation. This shared victory is a bit strange considering that the complete Squadriglia uses only 820 round of ammunition during the prolonged actions, in fact it seems that it possibly was an individual victory of Tenente Lucchini. His biographer Antonio Trizzino described the action:
“in the fading light of twilight Lucchini discovered something on his port side, something like the striking of three wax matches. He left the formation and went in that direction. Gradually closing he better understood what had happened. Three S 79s were falling, burning like torches and four Hurricanes were orbiting over as if they were recomposing formation before turning back home. He attacked the last one and shot it down.”
The 10o Gruppo fighters were back at 16:40; Sergente Sclavo’s CR.42, damaged in the engagement, was classified R.S.
The British fighters responsible for this execution were ten Hurricanes from 274 Squadron accompanied by the four newcomers from 73 Squadron. The 274 Squadron pilots had taken off at 15 minutes interval starting from 12:20. The pilots included Pilot Officer Ernest Mason (Hurricane P3720) (13:00-15:40), Flying Officer Thomas Patterson (P2544/YK-T) (13:30-16:10), Flight Lieutenant Peter Wykeham-Barnes (V7293) (13:45-16:15), Sergeant Thomas Morris (V7300) (14:00-16:30) and Flying Officer H. C. Down (P2556). The four pilots from 73 Squadron were Flight Lieutenant J. D Smith, Pilot Officer McFadden, Sergeant Alfred Marshall and Sergeant Willis.
Back at base, the British pilots claimed six SM 79s shot down five miles south of Gambut between 15:35 and 15:45. Two by Flying Officer Patterson at 15:45, one by Flight Lieutenant Wykeham-Barnes at 15:35, two by Sergeant Marshall and one by Flight Lieutenant Smith. A CR.42 was damaged and claimed as “unconfirmed” at 15:20 by Pilot Officer Mason. Looking at the Italian losses (the three SM 79s of the 9o Stormo with a fourth that crash-landed and the other two damaged, plus Sergente Sclavo’s damaged CR.42), British claims seem really accurate.
Flight Lieutenant Wykeham-Barnes had been alone when he at 15:35 discovered a mixed formation of SM 79s and CR.42s with four more SM 79s scattered around. He was flying at 19,000 feet and the Italian aircraft were 1,500 feet lower and 15 miles away from him. He delivered an astern attack one an SM 79 that seems to have been part of the 9 the 9o Stormo’s formation already attacked by other British pilots. He reported:
“Arrived late in combat, 1 S79 fired on, guns silenced. A/c dropped and starboard engine set on fire. Confirmed shot down by Flight Lieutenant Smith. While attacking 79 1 CR 42 got on my tail and fired on me. Two other overhead. Didn’t see them approach. Obliged to break off [unreadable].”
Flying Officer Patterson was flying with another Hurricane (Sergeant Marshall) when at 15:45 they discovered six SM 79s flying in two vics of three (obviously Colonnello Aramu’s formation). He was flying at 17,000 feet while the bombers appeared to be at 4,000 feet. He approached unseen until he was half a mile away and delivered an astern attack while they return fire diving towards the ground. He reported:
“3 S79 shot down and burnt out on ground (confirmed by Sergeant Marshall) our casualties nil.”
Sergeant Marshall remembered:
“after breakfast and meeting Flying Officer Patterson of 274, we flew up to Sidi Barrani, where we refuelled and took off on an Offensive Patrol. I flew with Pat and at 17,000 feet west of Sollum we spotted some 79s at about 5000 feet. We dived and engaged them and I got two in flames, Pat two and Smithy 1. There were congratulations from Collishaw (AOC) on our return, but I still wished it was all over and I could get back to UK – my cold was still bad, which didn’t help, plus the food and conditions were awful with half a gallon of water per day per man (Perhaps!).”
They were highly likely the victors of Aramu, Grandjacquet and Tonachella.
Pilot Officer Mason was flying with Sergeant Willis when at 15:20 he saw a lone CR.42 below and ahead approaching. He was flying at 15,000 feet and the Italian biplane was 2,000 feet lower. He delivered a head-on attack from very close range. He reported:
“Enemy pulled up and spun. A further burst was fired by Sergeant Willis. Enemy observed to spin to a low height until lost sight of. Possible presence of other a/c precluded following down to see it hit the ground.”
Pilot Officer McFadden, was chased “up country” by two Italian CR.42s where he force-landed reportedly owing to lack of fuel. He returned to Sidi Haneish the day after and Sergeant Marshall noted:
“McFadden came back from Mersa after breaking his kite – What a prize pilot he is!”
Pilot Officer MacFadden’s Hurricane (V6737) was later recovered and repaired. Considering the 90a Squadriglia’s records it seems possible that the crash-landing of McFadden was not due only to lack of fuel but perhaps also to damage suffered from the fire of Tenente Lucchini.

The last Italian bombing mission of the day on 27 December was again against Sollum. Four SM 79s from the 41o Stormo under Tenente Colonnello D’Ippolito and four bombers from the 216a Squadriglia, 34o Stormo, led by Tenente Romanini took off from Tmini at 14:30.
They were escorted by fighters from the 23o Gruppo and 10o Gruppi. Maggiore Tito Falconi was at the head of the formation of the first unit, which also included Tenente Claudio Solaro, Sottotenente Oscar Abello and Sergente Ubaldo Marziali from the 70a Squadriglia, Tenente Mario Pinna, Sottotenente Milano Pausi and Sergente Giuseppe Sanguettoli from the 74a Squadriglia and Tenente Pietro Calistri, Tenente Ezio Maria Monti, Maresciallo Giovanni Carmello, Sergente Leo Mannucci and Sottotenente Leopoldo Marangoni from the 75a Squadriglia.
It seems that the bomber formation split and the 41o Stormo attacked British mechanized units in Halfaya and Gabr Bu Fares under heavy AA that damaged, although slightly, all the aircraft. The SM 79s of the 34o Stormo attacked ships in Sollum harbour and were intercepted by many Hurricanes. The SM 79s were totally unable to defend themselves because of icing on all the guns and one of them was shot down. This was Sottotenente Aldo Peterlini’s bomber and Peterlini was killed together with three of his crew (Sergente Maggiore Arturo Scagnetti (second pilot), Aviere Scelto Motorista Alcide Frizzera and Aviere Scelto Radiotelegrafista Gioacchino Scuderi). The other two members of the crew (Primo Aviere Armiere Ciancilla and Primo Aviere Montatore Fiore) where able to bale out. Tenente Pandolfi’s aircraft was riddled by enemy bullets (probably RD) while the other two SM 79s were less seriously damaged although suffering some wounded among their crews.
They had been intercepted by 33 Squadron which claimed three SM 79s and one probable and probably two CR.42s during offensive patrols performed by pairs of Hurricanes over Sollum. They also claimed one SM 79 and one CR.42 damaged. Vernon Woodward claimed one of the probable CR.42s and the damaged CR.42.
Falconi’s pilots recorded combat with many Hurricanes, one of which was claimed as probable by the 70a Squadriglia and six more were damaged. Tenente Solaro and Sottotenente Abello returned with damaged fighters. Solaro had been hit by AA fire and Sottotenente Abello by British fighters. Calistri and his men claimed a shared Hurricane and four more damaged. They landed back at 16:55. A shot down Hurricane was also recorded by the 74a Squadriglia, which also recorded a SM 79 shot down by AA fire.
The CR.42 escort from the 10o Gruppo was composed of seven fighters from the 90a Squadriglia (Tenente Giovanni Guiducci, Tenente Franco Lucchini, Sottotenente Alessandro Rusconi, Sottotenente Neri De Benedetti, Sergente Alfredo Sclavo, Sergente Bortoletti and Sergente Enrico Botti), six from the 84a Squadriglia (Capitano Luigi Monti, Tenente Antonio Angeloni, Sottotenente Bruno Devoto, Sergente Maggiore Salvatore Mechelli, Sergente Domenico Santonocito and Sergente Piero Buttazzi) and six from the 91a Squadriglia (Maggiore Carlo Romagnoli, Capitano Vincenzo Vanni, Sottotenente Andrea Dalla Pasqua, Sottotenente Orlando Mandolini, Sottotenente Ennio Grifoni and Sergente Elio Miotto). Tenente Guiducci reported that the heavy AA immediately hit one of the SM 79s, which was shot down. Then five monoplanes (Hurricanes and Spitfires(!)) tried to attack but were immediately counterattacked and one of them was shot down. Later, another attempt by a lone British fighter failed after the intervention of the Italian escort. The 90a Squadriglia pilots expanded 320 rounds of ammunition and it seems that in the end the victory was assigned to the whole formation as a Gruppo victory. It seems that it was the same aircraft claimed independently by the two Squadriglie of the 23o Gruppo.

In January 1941, the 10o Gruppo was withdrawn to Italy to re-equip with the Macchi MC.200 and in April they operated from Ronchi with 23 MC.200s against Yugoslavia.

On 16 June 1941, 10o Gruppo moved to Trapani, Sicily to take part in the attacks on Malta.

By the end of 1941, the 4o Stormo re-equipped with Macchi MC.202s.

In early May 1942, the 4o Stormo was in Sicily with the duty of bomber escort over Malta.
On 22 May the 10 Gruppo returned to North Africa and to Martuba 4 airfield for a second desert tour.

On 1 July, the 10o Gruppo transferred to Fuka.

On 11 September, twelve Folgores from the 90a and the 91a Squadriglie, led respectively by Capitano Ranieri Piccolomini and Capitano Carlo Maurizio Ruspoli di Poggio Suasa, intercepted fifteen bomb-laden P-40s at 2000 m, covered by ten Spitfires at 4000 m over El Alamein-El Hammam. While the 91a Squadriglia attacked the P-40s (which jettisoned their bombs in the sea) and the 90a Squadriglia attacked the Spitfires, eight other Spitfires dived unseen on them from 6000 m. A hard fight began and lasted for over twenty minutes until 60 km east of El Alamein. Piccolomini, Sergente Maggiore Giovanni Silvestri (91a Squadriglia) and Sottotenente Luciano Barsotti (91a Squadriglia) claimed a P-40 each, while Sottotenente Orlando Mandolini (91a Squadriglia) claimed a Spitfire. Another Spitfire was claimed as a shared probable by Tenente Luigi Padovani, Sergente Maggiore Angelo Savini, Sottotenente Sforza Libera and Sergente Maggiore Bortoletti (all from the 90a Squadriglia). Many others were claimed damaged. Five Macchis were hit, but returned back to base; Savini’s, Libera’s and Sergente Maggiore Leonardo Ferrulli’s aircraft were damaged, as was Barsotti’s, who also was lightly wounded, as was Padovani, who received a bulled in his left leg. Bortoletti, with his Folgore riddled by a Spitfire, made an emergency landing near Hisiyet Busata.

After the battle of El Alamein, the Axis forces gradually retreated. In early December, the 10o Gruppo was at Castelbenito to be sent back to Italy.
During the period January 1942 – January 1943, the 4o Stormo flew 7202 hours on missions, took part in 133 combats, claimed 289 aircraft destroyed (totally 501 from the beginning of the war) and lost 24 pilots KIA or MIA with 29 wounded and 2 POWs.

After a period of rest, on 24 February 1943, pilots of the 10o Gruppo rejoined to reorganize the unit at Bresso airfield, under the command of Maggiore Giuseppe D’Agostinis.
Pilots in the 84a Squadriglia were Capitano Franco Lucchini (CO) (hospitalized), Tenente Luigi Giannella, Tenente Alessandro Mettimano, Sottotenente Francesco De Seta, Sottotenente Ugo Picchiottini, Maresciallo Luigi Bignami, Sergente Maggiore Domenico Santonocito, Sergente Maggiore Corrado Patrizi, Sergente Maggiore Piero Buttazzi, Sergente Maggiore Luciano Perdoni and Sergente Livio Barbera.
Pilots in the 90a Squadriglia were Capitano Ranieri Piccolomini (CO), Sottotenente Sforza Libera, Sottotenente Renato Baroni, Sottotenente Luigi Cima, Sergente Maggiore Massimo Salvatore, Sergente Maggiore Bortoletti, Sergente Maggiore Giovanni Battista Ceoletta, Sergente Maggiore Amleto Monterumici and Sergente Maggiore Natale Molteni.
Pilots in the 91a Squadriglia were Capitano Luigi Mariotti (CO), Tenente Giuseppe Ferazzani, Tenente Alvaro Bondi, Sottotenente Leonardo Ferrulli, Sottotenente Elio Miotto, Sottotenente Guerriero Silvestri, Sottotenente Vittorino Daffara, Maresciallo Alessandro Bladelli, Maresciallo Lamberto Martelli, Sergente Maggiore Ferruccio Terrabujo, Sergente Ambrogio Rusconi and Sergente Giulio Fornalé.
On 20 April, the Gruppo transferred to Ciampino Sud for the defence of Rome.

Bortoletti ended the war with 4 shared biplane victories.
