Now at last he was free; and, in spite of the earnest remonstrances of Doria and the entreaties of the Pope, to Algiers he would go. Everything had long been prepared--a month, he believed, at the outside would finish the matter--in short, go he would. At Spezzia he embarked on Doria's flagship; the Duke of Alva, of sanguinary memory, commanded the troops, many of whom had been brought by the Emperor himself from the German highlands. Ill-luck attended them from the outset: a storm, no unusual phenomenon with November coming on, drove the ships back into shelter at Corsica. At length the seas subsided, and the fleet, picking up allies as it went along, cautiously hugged the land as far as Minorca, where the mistral, the terror of seamen, rushed down upon the huge armada--masts strained, yards cracked, sails were torn to rags, and there was nothing for it but to row--row for their lives and for Charles. They were but seven miles from Port Mahon, yet it took half the night to win there--an endless night which the panting crews never forgot. In the bay of Palma, at Majorca, the fleet was assembled. There were the Emperor's hundred sailing vessels carrying the German and Italian troops, commanded by such historic names as Colonna and Spinosa; there were Fernando Gonzago's Sicilian galleys, and a hundred and fifty transports from Naples and Palermo; there were the fifty galleys of Bernadino de Mendoza, conveying two hundred transports with the arms and artillery, and carrying the corps of gentlemen adventurers, mustered from the chivalry of Spain, and including one only who had climbed up from the ranks--but that one was Cortes, the conqueror of Mexico. Over five hundred sail, manned by twelve thousand men, and carrying a land force of twenty-four thousand soldiers, entered the roads of Algiers on October 19, 1541. [Illustration: SIEGE OF ALGIERS, 1541. (_From a map in the British Museum._)] At last the great Emperor set eyes upon the metropolis of piracy. On the rocky promontory which forms the western crest of the crescent bay, high up the amphitheatre of hills, tier upon tier, in their narrow overshadowed lanes, the houses of the Corsairs basked in the autumn sun, crowned by the fortress which had known the imperious rule of two Barbarossas. On the right was the mole which Spanish slaves had built out of the ruins of the Spanish fort. Two gates fronted the south and north, the Bab Azūn and Bab-el-Wēd.
