On August of the same year, the unit made way by Meknes in Morocco, in order to assault Gibraltar. That mission being canceled, the Group went back to Blida, the latter becoming the base garrison. While recompleting formations, the latter received another designation as a light bombardment group - Groupe de Bombardement Léger I/19 on September 1, 1940, while the 3rd and 4th Escadrilles became respectively the 1st and 2nd Escadrilles. On September 23 and 25, the Group partook in attacks led against Gibraltar, then went back to Blida. When the Allied disembarking in North Africa took place, in November 1942, the Group did not participate, but a little to the resistance, which opposed the Vichy Army () to the Anglo-Americans.

The Group underwent a long training session until October of the same year, époque where the latter was dissociated, certain elements expedited to Constantine (1st Escadrille), the others to Sétif (2nd Escadrille).
