On Garibaldi's return to Naples, he had soon to turn his attention from the city toward the strongholds to which the poor king had retired, in the northwestern extremity of his late kingdom. The only territory now remaining to him of "the Two Sicilies," was the remarkable promontory of Gaeta and the adjacent range of mountainous and hilly country, extending southwesterly a few miles, near the frontier of the Pope's dominions, and along the courses of the rivers Volturno and Garigliano, to the heights of Capua. Gaeta and Capua have long been strong fortresses, and have known, at different periods, the hard fate of war. In Gaeta the present pope found a refuge, when he fled from Rome in 1848; thence were sent the calls to his spiritual subjects in all countries, to make contributions of "Peter's pence," and the demands on "Catholic powers," to reinstate the "Gentle Shepherd" in his sheepfold—by force of arms. That call was answered by four monarchs; one of whom, the savage father of the now fugitive King of Naples, had his armies, too, routed by the now victorious Garibaldi; and another, Louis Napoleon, after having his advance of 8,000 men driven back by the same hero, at the point of the bayonet, afterward, by false faith and overwhelming numbers, took the city by fraud and bombshells, and, on one pretext and another, has held it to the present time. He, however, has recently done so much for Italy, and seems resolved to do so much more, that her friends gladly indulge the hope, that he will continue a course quite the opposite of that which history was compelled to record nearly twelve years ago, and which posterity will ever be compelled emphatically to condemn. A description of Gaeta, Capua, and Caserta will be necessary to many readers, before a connected account is given of the important military events which took place in that remarkable vicinity in October and November, 1860. The traveller who leaves Naples for Rome, soon joins the route taken by the Apostle Paul from Puteoli. He first crosses the Campagna di Lavoro (country of labor), formerly called by the Romans, the Campania Felix (happy country), and now covered with countless fields, pastures, gardens and forests of vineyards. At the distance of about twenty miles, he reaches the foot of the bare mountain range above mentioned, where are seen the ruins of ancient Capua; and after winding among eminences—among scenes desolate compared with those he has seen—and crossing the Volturno and the Garigliano, he stops at Castello or Mola di Gaeta. From the windows or terrace of the post-house he looks out through a garden of flowers and orange-trees, upon a fine bay, several miles across, the shores of which, low and curving round on the right, extend to a high, round mountain opposite, where a city is seen at its foot, and the zigzag walls and batteries of a mighty fortress on its sides and summit. That is Gaeta.
