At the beginning of August 1936, Alberto Bayo was in charge of carrying out the landing operation for the Battle of Majorca, then under the control of the nationalist military. On August 6, preparations for the seizure concluded and the Central Committee of Antifascist Militias of Catalonia lent logistical support. On August 16, around 6,000 to 10,000 men landed in Mallorca and engaged in combat between Punta Amer and Porto Cristo, in the eastern part of the island. These troops were formed out of the Menorca garrison, which remained faithful to the Republic, and volunteers from republican political and union organizations.
