Scarcely had he dispatched these letters, written under a state of excitement almost amounting to frenzy, when Herrera, in pursuance of a previously formed plan, and as if to stifle the regrets which a forced and painful determination occasioned him, hastened to join as a volunteer the nearest Christino column. It was one commanded by General Lorenzo, then operating against Santos Ladron and the Navarrese Carlists. In several skirmishes Herrera signalized himself by the intrepidity and fury with which he fought. Ladron was taken and shot, and Lorenzo marched to form the advanced guard of a strong division which, under the command of Sarsfield, was rapidly nearing the scene of the insurrection. On the mere approach of the Christino army, the battalions of Castilian Realistas, which formed, numerically speaking, an important part of the forces then under arms for Don Carlos, disbanded themselves and fled to their homes. Sarsfield continued his movement northwards, took possession, after trifling resistance, of Logroño, Vittoria, Bilboa, and other towns occupied by the Carlists; and, after a few insignificant skirmishes, succeeded in dispersing and disarming the whole of the insurgents in the three Basque provinces. A handful of badly armed and undisciplined Navarrese peasants were all that now kept the field for Charles V., and of the rapid capture or destruction of these, the sanguine Christinos entertained no doubt. The principal strength of the Carlists was broken; their arms were taken away; the majority of the officers who had joined, and of the men of note and influence in the country who had declared for them, had been compelled to cross the Pyrenees. But the tenacious courage and hardihood of the Navarrese insurgents, and the military skill of the man who commanded them, baffled the unceasing pursuit kept up by the Queen's generals. During the whole of the winter the Carlists lived like wolves in the mountains, surrounded by ice and snow, cheerfully supporting the most incredible hardships and privations. Nay, even under such disadvantageous circumstances, their numbers increased, and their discipline improved; and when the spring came they presented the appearance, not of a band of robbers, as their opponents had hitherto designated them, but of a body of regular troops, hardy and well organized, devoted to their general, and enthusiastic for the cause they defended. Their rapid movements, their bravery and success in several well-contested skirmishes, some of which almost deserved the name of regular actions, the surprise of various Christino posts and convoys, the consistency, in short, which the war was taking, began seriously to alarm the Queen's government; and the formidable preparations made by the latter for a campaign against the Carlists, were a tacit acknowledgment that Spain was in a state of civil war.
In the wild and beautiful valley of the Lower Amezcoa, in the merindad or district of Estella, a large body of Christino troops was assembled on the fifteenth day after Rodil's entrance into Navarre. The numerous forces which that general found under his command, after uniting the troops he had brought with him with those already in the province, had enabled him to adopt a system of occupation, the most effectual, it was believed, for putting an end to the war. In pursuance of this plan, he established military lines of communication between the different towns of Navarre and Alava, garrisoned and fortified the principal villages, and having in this manner disseminated a considerable portion of his army through the insurgent districts, he commenced, with a column of ten thousand men that remained at his disposal, a movement through the mountainous regions, to which, upon his approach, the Carlists had retired. His object was the double one of attacking and destroying their army, and, if possible, of seizing the person of Don Carlos, who but a few days previously had arrived in Spain. The heat of the weather was remarkable, even for that usually sultry season; the troops had had a long and fatiguing march over the rugged sierra of Urbasa; and Rodil, either with a view of giving them rest, or with some intention of garrisoning the villages scattered about the valley, which had hitherto been one of the chief haunts of the Carlists, had come to a halt in the Lower Amezcoa.
It was two in the afternoon, and, notwithstanding the presence of so large a body of men, all was stillness and repose in the valley. The troops had arrived that morning, and after taking up their cantonments in the various villages and hamlets, had sought refuge from the overpowering heat. In the houses, the shutters of which were carefully closed to exclude the importunate sunbeams, in the barns and stables, under the shadow cast by balconies or projecting eaves, and along the banks of the stream which traverses the valley, and is noted in the surrounding country for the crystal clearness and extreme coldness of its waters, the soldiers were lying, their uniforms unbuttoned, the stiff leathern stock thrown aside, enjoying the mid-day slumber, which the temperature and their recent fatigue rendered doubly acceptable. Here and there, at a short distance from the villages, and further off, near the different roads and passes that give access to the valley through or over the gigantic mountain-wall by which it is encircled, the sun flashed upon the polished bayonets and musket-barrels of the pickets. The men were lying beside their piled arms, or had crept under some neighbouring bush to indulge in the universal siesta; and even the sentries seemed almost to sleep as they paced lazily up and down, or stood leaning upon their muskets, keeping but a drowsy watch and careless look-out for an enemy whose proximity was neither to be anticipated nor dreaded by a force so superior to any which he could get together.
Such was the scene that presented itself to one who, having approached the valley from the south, and ascended the mountains that bound it on that side, now contemplated from their summit the inactivity of its occupants. He was a man of the middle height, but appearing rather shorter, from a slight stoop in the shoulders; his age was between forty and fifty years, his aspect grave and thoughtful. His features were regular, his eyes clear and penetrating, a strong dark mustache covered his upper lip and joined his whisker, which was allowed to extend but little below the ear. His dress consisted of a plain blue frock, girt at the waist by a belt of black leather, to which a sabre was suspended, and his head was covered with a boina, or flat cap, of the description commonly worn in the neighbourhood of the Pyrenees, woven in one piece of fine scarlet wool, and decorated with a borla, or tassel of gold cord, spreading like a star over the crown of the head. In his hand he held a telescope, which he rested on the top of a fragment of rock, and through which he attentively noted what passed in the valley below. The case of the field-glass was slung across his body by a strap, and, upon inspection, a name would have been found stamped upon its leathern surface. It was that of Tomas Zumalacarregui.
A short distance in rear of the Carlist leader, and so posted as not to be visible from the valley, stood a little group of officers, and persons in civilian garb, and a few orderlies, one of whom held the general's horse. Behind, a battalion of infantry was drawn up – fine, muscular, active fellows, inured to every hardship, and as indifferent to the scorching heat to which they were now exposed, as they had been to the bitter cold in the mountains amongst which they had passed the preceding winter. Their appearance was not very uniform in its details; short jackets, loose trousers, and sandals, composed the dress of most of them – one well adapted to long marches and active movements – and they all wore caps similar to those of the officers, but of a blue colour, and coarser material. A second battalion of these hardy guerillas was advancing with light and elastic step up the rugged and difficult path; and this was followed by two others, which, as fast as they arrived, were formed up by their officers in the best manner that the uneven nature of the ground would admit. Half a dozen mules, laden with ammunition, brought up the rear. When the four battalions, consisting together of nearly three thousand men, were assembled on the summit of the mountain, the arms were piled, and the soldiers allowed to sit down or repose themselves as they chose from the fatigues of their long and wearisome ascent, and of a march that had
