Barbarossa landed 2,500 Moors and some guns, with which he battered the walls of the town and made a breach. His assault was, however, repulsed. The people of Ciudadela assembled three hundred men, but seeing that the enemy was so powerful they did not venture upon an attack at first. They sent a messenger to warn the besieged that they should be ready to make a sortie when the relief approached. Then most of the three hundred advanced, and occupied the attention of the enemy while the besieged hastily repaired the breaches in the walls. A second assault was gallantly repulsed, and the pirate chief began to feel rather insecure at Port Mahon, expecting the return of the Emperor’s fleet from Tunis. Fortunately for Barbarossa, the besieged lost heart and surrendered the town to him on terms which he never dreamt of keeping. He made slaves of eight hundred of the inhabitants. The churches were pillaged and profaned. The Guardian of San Francisco had partaken of the Sacrament to save the Host from profanation. The Moors entered and seized all the valuables, but did not find the Host in the pyx. Barbarossa asked where it was, and when the Franciscan replied that he had eaten it to preserve it from profanation, he was ordered out for execution and suffered death with two other friars. This was in the year 1536. The Governor of the island had remained at Ciudadela, and when six citizens arrived from Port Mahon, who had been released by Barbarossa because they advised the surrender, the Governor ordered them to be put to death. Barbarossa and his Moors evacuated Port Mahon and departed with his plunder and with many wretched people to be sold into slavery. The Emperor was greatly distressed at these repeated acts of piracy, and in 1541 he fitted out a second expedition, this time against Algiers. Again he led the expedition in person; but it was a failure owing to the furious gales and deluges of rain.
