While Gonsalvo lay before Gaeta, he had been intent on collecting such reinforcements as he could from every quarter. The Neapolitan division under Navarro had already joined him, as well as the victorious legions of Andrada from Calabria. His strength was further augmented by the arrival of between two and three thousand troops, Spanish, German, and Italian, which the Castilian minister, Francisco de Roxas, had levied in Rome; and he was in daily hopes of a more important accession from the same quarter, through the good offices of the Venetian ambassador. Lastly, he had obtained some additional recruits, and a remittance of a considerable sum of money, in a fleet of Catalan ships lately arrived from Spain. With all this, however, a heavy amount of arrears remained due to his troops. In point of numbers he was still far inferior to the enemy; no computation swelling them higher than three thousand horse, two of them light cavalry, and nine thousand foot. The strength of his army lay in his Spanish infantry, on whose thorough discipline, steady nerve, and strong attachment to his person he felt he might confidently rely. In cavalry, and still more in artillery, he was far below the French, which, together with his great numerical inferiority, made it impossible for him to keep the open country. His only resource was to get possession of some pass or strong position, which lay in their route, where he might detain them, till the arrival of further reinforcements should enable him to face them on more equal terms. The deep stream of the Garigliano presented such a line of defence as he wanted. [15]
On the 6th of October, therefore, the Great Captain broke up his camp at Castellone, and, abandoning the whole region north of the Garigliano to the enemy, struck into the interior of the country, and took post at San Germano, a strong place on the other side of the river, covered by the two fortresses of Monte Casino [16] and Rocca Secca. Into this last he threw a body of determined men under Villalba, and waited calmly the approach of the enemy.
It was not long before the columns of the latter were descried in full march on Ponte Corvo, at a few miles' distance only on the opposite side of the Garigliano. After a brief halt there, they traversed the bridge before that place and advanced confidently forward in the expectation of encountering little resistance from a foe so much their inferior. In this they were mistaken; the garrison of Rocca Secca, against which they directed their arms, handled them so roughly, that, after in vain endeavoring to carry the place in two desperate assaults, the marquis of Mantua resolved to abandon the attempt altogether, and, recrossing the river, to seek a more practicable point for his purpose lower down. [17]
Keeping along the right bank, therefore, to the southeast of the mountains of Fondi, he descended nearly to the mouth of the Garigliano, the site, as commonly supposed, of the ancient Minturnae. [18] The place was covered by a fortress called the Tower of the Garigliano, occupied by a small Spanish garrison, who made some resistance, but surrendered on being permitted to march out with the honors of war. On rejoining their countrymen under Gonsalvo, the latter were so much incensed that the garrison should have yielded on any terms, instead of dying on their posts, that, falling on them with their pikes, they massacred them all to a man. Gonsalvo did not think proper to punish this outrage, which, however shocking to his own feelings, indicated a desperate tone of resolution, which he felt he should have occasion to tax to the utmost in the present exigency. [19]
The ground now occupied by the armies was low and swampy, a character which it possessed in ancient times; the marshes on the southern side being supposed to be the same in which Marius concealed himself from his enemies during his proscription. [20] Its natural humidity was greatly increased, at this time, by the excessive rains, which began earlier and with much more violence than usual. The French position was neither so low nor so wet as that of the Spaniards. It had the advantage, moreover, of being supported by a well-peopled and friendly country in the rear, where lay the large towns of Fondi, Itri, and Gaeta; while their fleet, under the admiral Prejan, which rode at anchor in the mouth of the Garigliano, might be of essential service in the passage of the river.
In order to effect this, the marquis of Mantua prepared to throw a bridge across, at a point not far from Trajetto. He succeeded in it, notwithstanding the swollen and troubled condition of the waters, [20] in a few days, under cover of the artillery, which he had planted on the bank of the river, and which from its greater elevation entirely commanded the opposite shore.
The bridge was constructed of boats belonging to the fleet, strongly secured together and covered with planks. The work being completed, on the 6th of November the army advanced upon the bridge, supported by such a lively cannonade from the batteries along the shore, as made all resistance on the part of the Spaniards ineffectual. The impetuosity with which the French rushed forward was such as to drive back the advanced guard of their enemy, which, giving way in disorder, retreated on the main body. Before the confusion could extend further, Gonsalvo, mounted á la gineta, in the manner of the light cavalry, rode through the broken ranks, and, rallying the fugitives, quickly brought them to order. Navarro and Andrada, at the same time, led up the Spanish infantry, and the whole column charging furiously against the French, compelled them to falter and at length to fall back on the bridge.
The struggle now became desperate, officers and soldiers, horse and foot, mingling together, and fighting hand to hand, with all the ferocity kindled by close personal combat. Some were trodden under the feet of the cavalry, many more were forced from the bridge, and the waters of the Garigliano were covered with men and horses, borne down by the current, and struggling in vain to gain the shore. It was a contest of mere bodily strength and courage, in which skill and superior tactics were of little avail. Among those who most distinguished themselves, the name of the noble Italian, Fabrizio Colonna, is particularly mentioned. An heroic action is recorded also of a person of inferior rank, a Spanish alferez, or standard-bearer, named Illescas. The right hand of this man was shot away by a cannon-ball. As a comrade was raising up the fallen colors, the gallant ensign resolutely grasped them, exclaiming that "he had one hand still left." At the same time, muffling a scarf round the bleeding stump, he took his place in the ranks as before. This brave deed did not go unrewarded, and a liberal pension was settled on him, at Gonsalvo's instance.
During the heat of the mêlée, the guns on the French shore had been entirely silent, since they could not be worked without doing as much mischief to their own men as to the Spaniards, with whom they were closely mingled. But, as the French gradually recoiled before their impetuous adversaries, fresh bodies of the latter rushing forward to support their advance necessarily exposed a considerable length of column to the range of the French guns, which opened a galling fire on the further extremity of the bridge. The Spaniards, notwithstanding "they threw themselves into the face of the cannon," as the marquis of Mantua exclaimed, "with as much unconcern as if their bodies had been made of air instead of flesh and blood," found themselves so much distressed by this terrible fire, that they were compelled to fall back; and the van, thus left without support, at length retreated in turn, abandoning the bridge to the enemy. [21]
This action was one of the severest which occurred in these wars. Don Hugo de Moncada, the veteran of many a fight by land and sea, told Paolo Giovio that "he had never felt himself in such imminent peril in any of his battles, as in this." [22] The French, notwithstanding they remained masters of the contested bridge, had met with a resistance which greatly discouraged them; and, instead of attempting to push their success further, retired that same evening to their quarters on the other side of the river. The tempestuous weather, which continued with unabated fury, had now broken up the roads, and converted the soil into a morass, nearly impracticable for the movements, of horse, and quite so for those of artillery, on which the French chiefly relied; while it interposed comparatively slight obstacles to the manoeuvres of infantry, which constituted the strength of the Spaniards. From a consideration of these circumstances, the French commander resolved not to resume active operations till a change of weather, by restoring the roads, should enable him to do so with advantage. Meanwhile he constructed a redoubt on the Spanish extremity of the bridge, and threw a body of troops into it, in order to command the pass whenever he should be disposed to use it. [23]
