The 13^o Gruppo (77^a, 78^a and 82^a Squadriglie) of the 2^o Stormo C.T. was commanded by Maggiore Secondo Revetria and started the war based at Tripoli Castelbenito airfield with twenty-five CR.42s and eleven CR.32s on hand (the CR.32s, kept as a reserve, were later passed on to the 50^o Stormo Assalto) to guard against a possible French attach from the west.
Pilots in the 77^a Squadriglia were: Capitano Mario Fedele (CO), Tenente Sorvillo (recently arrived from 4^o Stormo), Tenente Giulio Torresi, Sottotenente Gianmario Zuccarini, Sottotenente Mario Fabbricatore, Sergente Maggiore Ernesto Scalet, Sergente Maggiore Leone Basso, Sergente Maggiore Agostino Fausti, Sergente Raoul Scodellari, Sergente Ernesto Paolini, Sergente Botti (recently arrived from 53^o Stormo), Sergente Amedeo Benati and Sergente Vincenzo Campolo. These pilots had twelve CR.42s (including Maggiore Revetria’s and Colonnello Federici’s) (eight combat ready and three still under assembly) and four CR.32quaters.

On 25 December, Sergente Botti and Sergente Armando Angelini were assigned to the 90^a Squadriglia, , 10^o Gruppo C.T., in North Africa. This unit was at the time equipped with Fiat CR.42s.
On the same date, 25 December, the 23^o Gruppo flew its first escorting missions after its arrival in the theatre, one of these was at 15:00 with 12 CR.42s in collaboration with 22 CR.42s from the 10^o Gruppo, which had taken off at 14:35 to escort the 15^o Stormo’s SM 79s bound to attack Sollum Harbour.
The fighters from the 23^o included four from the 70^a Squadriglia (Maggiore Tito Falconi, Tenente Claudio Solaro, Sottotenente Oscar Abello and Sergente Maggiore Balilla Albani), four from the 74^a Squadriglia (Capitano Guido Bobba, Tenente Mario Pinna, Tenente Lorenzo Lorenzoni and Sergente Emilio Stefani) and four from the 75^a Squadriglia (Tenente Pietro Calistri, Tenente Ezio Maria Monti, Sottotenente Giuseppe De Angelis and Maresciallo Giovanni Carmello). The fighters from the 10^o Gruppo included six CR.42s from the 91^a Squadriglia (Maggiore Carlo Romagnoli, Capitano Vincenzo Vanni, Sottotenente Ruggero Caporali, Sottotenente Andrea Dalla Pasqua, Sergente Maggiore Leonardo Ferrulli and Sergente Maggiore Lorenzo Migliorato), seven from the 90^a Squadriglia (Tenente Giovanni Guiducci, Tenente Franco Lucchini, Sottotenente Alessandro Rusconi, Sottotenente Neri De Benedetti, Sergente Alfredo Sclavo, Sergente Luigi Bagato and Sergente Botti) and nine from the 84^a Squadriglia (Capitano Luigi Monti, Tenente Antonio Angeloni, Sergente Maggiore Salvatore Mechelli, Sergente Domenico Santonocito, Sergente Luciano Perdoni, Sergente Corrado Patrizi, Sergente Piero Buttazzi, Sergente Mario Veronesi and Capitano Mario Pluda (91^a Squadriglia)).
The formation was attacked by some Hurricanes that were counter-attacked and obliged to flee. Two Hurricanes were claimed as probably shot down by the pilots of 90^a and 91^a Squadriglie (the 90^a Squadriglia used 160 rounds of ammunition), which claimed them as shared with the 23^o Gruppo even if the pilot from the 23^o Gruppo in fact weren’t able to claim anything. Tenente Guiducci landed at T5 with engine trouble while the rest of the formation landed at Z1 between 16:50 and 17:00. No losses were suffered by the bombers, which claimed to have hit an aircraft carrier. In fact, they aimed their bomb load at a monitor, but it is not known if the ship was in fact hit.
The Hurricanes were probably machines of 33 Squadron with Flying Officer Peter Wickham and Flying Officer Vernon Woodward that encountered one SM 79 and one CR.42, damaging the CR.42. The action was however recorded in the morning.

The last Italian bombing mission of the day on 27 December was again against Sollum. Four SM 79s from the 41^o Stormo under Tenente Colonnello D’Ippolito and four bombers from the 216^a Squadriglia, 34^o Stormo, led by Tenente Romanini took off from Tmini at 14:30.
They were escorted by fighters from the 23^o Gruppo and 10^o 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 70^a Squadriglia, Tenente Mario Pinna, Sottotenente Milano Pausi and Sergente Giuseppe Sanguettoli from the 74^a Squadriglia and Tenente Pietro Calistri, Tenente Ezio Maria Monti, Maresciallo Giovanni Carmello, Sergente Leo Mannucci and Sottotenente Leopoldo Marangoni from the 75^a Squadriglia.
It seems that the bomber formation split and the 41^o 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 34^o 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 70^a 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 74^a Squadriglia, which also recorded a SM 79 shot down by AA fire.
The CR.42 escort from the 10^o Gruppo was composed of seven fighters from the 90^a Squadriglia (Tenente Giovanni Guiducci, Tenente Franco Lucchini, Sottotenente Alessandro Rusconi, Sottotenente Neri De Benedetti, Sergente Alfredo Sclavo, Sergente Bruno Bortoletti and Sergente Botti), six from the 84^a 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 91^a 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 90^a 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 23^o Gruppo.

On 17 July 1941, 49 MC.200s from the 7^o, 10^o and 16^o Gruppi set off mid morning to escort one reconnaissance Z.1007bis over Malta. En route the 16^o Gruppo fighters became separated and returned to base, but the rest of the formation reached the island where eight Hurricanes of 249 Squadron and eleven from 185 Squadron had been scrambled. The aircraft from the former unit made contact, Squadron Leader Robert Barton (Hurricane Z3262) claiming one MC.200 shot down in flames, while Pilot Officer P. G. Leggett claimed a second and Flying Officer C. C. H. Davis one damaged. Two MC.200s of the 10^o Gruppo were in fact lost when Sergente Maggiore Botti (MC.200 MM6500) and Sergente Maggiore Natale Fiorito (MC.200 MM5217) where killed. In return the pilots of the 10^o Gruppo claimed four Hurricanes and two probables. Tenente Colonnello Carlo Romagnoli and Capitano Franco Lucchini each claimed one Hurricane shot down and Sergente Maggiore Elio Miotto two. Maresciallo Leonardo Ferrulli and Sergente Luigi Contarini each claimed probables. One Hurricane was lost when 22-year-old Sergeant Maurice Guest (RAF No. 920596) of 249 Squadron in Hurricane Z2818 failed to return.

At the time of his death, Botti was credited with 1 shared biplane victory.
