The sack of Mahón occurred in 1535, when Hayreddin Barbarossa attacked the harbour of Mahón in the Balearic Islands. The expedition followed closely the defeat of Barbarossa in the Conquest of Tunis by Charles V. Barbarossa had escaped Tunis and boarded his fleet in Bône. Mahón had no garrison, only one or two cannons and no ammunition or gunpowder stored. It had only 300 arms and about 1,500 inhabitants, of which only 350 were fit for military service. The capital of the island at the time was Ciutadella, which housed the garrison. Barbarossa took considerable booty and as many as 600-800 slaves whom he brought back to Algiers.
