On June 16th the armada arrived before Tunis, and the army disembarked to attack the fortress known as La Goletta. Into this strong place of arms Barbarossa had sent some six thousand of his best men, mostly Turkish soldiers, under the command of Sinan-Reis, a renegado Jew, and one of the fiercest and most faithful of his followers. To the camp of the Emperor came the fugitive King, Muley Hassan, in whose cause the armada had nominally been assembled—how nominal this was we shall see later by the light of the treaty concluded between him and the Emperor. Charles had complete command of the sea for the time being, and, in consequence, the ex-Sultan was amazed at the profusion and luxury which reigned in the camp of the Christians; and he concluded that these indeed must be the lords of the earth, as luxury and profusion was hardly the note of such courts as then existed in the northern portion of the African continent. Although the army was landed, and with it artillery for the bombardment of the Goletta, there remained, of course, “the army of the sea,” under the orders of the redoubtable Doria; and while the Marquis del Guasto, who was in supreme command on shore, prepared to batter down the defences of the fortress on the land side, the attack was carried on simultaneously from the sea by the galleys. The actual presence of the Emperor stimulated the various nationalities under his eyes to vie with one another in deeds of daring, and they contended among themselves for the posts of the most honour and danger. The attacks of the African horsemen were brushed on one side by the disciplined valour of the Andalusian cavalry, while the great guns thundered from land and sea against the walls of the doomed Goletta. Sinan and his Ottoman soldiers performed prodigies in the way of repairing breaches in the walls as soon as they were made; but Kheyr-ed-Din from the city watched the progress of the bombardment gloomily, as he saw and knew that the fall of the Goletta was but a matter of days. All this time he was far from idle; sortie after sortie did the dauntless old warrior lead in person against those engaged in the task of bombardment. Time and again he heartened the Arab and Berber levies to attack, but the sallies were repulsed, and the lightly armed Africans were driven like chaff before the wind when they swooped down on the lines of investment.
