In December 1530, Hayreddin Barbarossa, an Ottoman admiral of the fleet, captured the Castle of Cabrera, and started to use the island as a logistic base for his operations in the area.
[3] Late in 1916, a malfunctioning Austro-Hungarian Navy submarine remained at Cabrera for several hours, and the Spanish government subsequently decided to expropriate the island for defense.
It is alleged that Juan March Ordinas, avoiding the blockade, had been selling supplies, including fuel, to submarine personnel, from the area of Cala Ganduf and S'Olla.
After the failure of Captain Alberto Bayo Column landing in Mallorca, from 15 August to 4 September, the Republican troops left Cabrera.
Bayo's plan was for the CNT column, stationed in Cabrera, to appear at Dragonera Island just southwest of Mallorca and simulate a false landing.
