But whatever the cause of the victory, its consequence was to spread the name and fame of Don John of Austria throughout the world. Alva wrote, with enthusiasm, to congratulate him; pronouncing the victory the most brilliant one ever achieved by Christians, and Don John the greatest general since the death of Julius Caesar. At the same time, with a sarcastic fling at the erection of the Escorial, he advised Philip to improve this new success in some more practical way than by building a house for the Lord and a sepulchre for the dead. "If," said the Duke, "the conquests of Spain be extended in consequence of this triumph, then, indeed, will the Cherubim and Seraphim sing glory to God." A courier, despatched post haste to Spain, bore the glorious news, together with the sacred, standard of the Prophet, the holy of holies, inscribed with the name of Allah twenty-eight thousand nine hundred times, always kept in Mecca during peace, and never since the conquest of Constantinople lost in battle before. The King was at vespers in the Escorial. Entering the sacred precincts, breathless, travel-stained, excited, the messenger found Philip impassible as marble to the wondrous news. Not a muscle of the royal visage was moved, not a syllable escaped the royal lips, save a brief order to the clergy to continue the interrupted vespers. When the service had been methodically concluded, the King made known the intelligence and requested a Te Deum. The youthful commander-in-chief obtained more than his full mead of glory. No doubt he had fought with brilliant courage, yet in so close and murderous a conflict, the valor of no single individual could decide the day, and the result was due to the combined determination of all. Had Don John remained at Naples, the issue might have easily been the same. Barbarigo, who sealed the victory with his blood; Colonna, who celebrated a solemn triumph on his return to Rome; Parma, Doria, Giustiniani, Venieri, might each as well have claimed a monopoly of the glory, had not the Pope, at Philip's entreaty, conferred the baton of command upon Don John. The meagre result of the contest is as notorious as the victory. While Constantinople was quivering with apprehension, the rival generals were already wrangling with animosity. Had the Christian fleet advanced, every soul would have fled from the capital, but Providence had ordained otherwise, and Don John sailed westwardly with his ships. He made a descent on the Barbary coast, captured Tunis, destroyed Biserta, and brought King Amidas and his two sons prisoners to Italy. Ordered by Philip to dismantle the fortifications of Tunis, he replied by repairing them thoroughly, and by placing a strong garrison within the citadel. Intoxicated with his glory, the young adventurer already demanded a crown, and the Pope was disposed to proclaim him King of Tunis, for the Queen of the Lybian seas was to be the capital of his Empire, the new Carthage which he already dreamed.
