Second Battle of Sauroren. (July, 1813.)
Picton quickly gained the Val de Zubiri, and threw his skirmishers against Foy’s left flank on the mountain, while on the other flank General Inglis, one of those veterans who purchase every step of promotion with their blood, advancing with only five hundred men of the seventh division, broke at one shock the two French regiments on the ridges covering Clausel’s right, and drove them down into the valley of Lanz. He lost indeed one-third of his own men, but instantly spread the remainder in skirmishing order along the descent and opened a biting fire upon the flank of Conroux’s division, which being in march up the valley from Sauroren, was now thrown into disorder by having two regiments thus suddenly tumbled upon it from the top of the mountain.
Foy’s division was marching along the crest of the position between Zabaldica and Sauroren at the moment of this attack; but he was too far off to give aid, and his own light troops were engaged with Cole’s skirmishers; moreover Inglis had been so sudden that before the evil was well perceived it was past remedy; for Wellington instantly pushed the sixth division under Pakenham to the left of Sauroren, and sent Byng headlong down from the chapel height against Maucune, who was in that village. This vigorous assault was simultaneously enforced from the other side of the Lanz by Madden’s Portuguese, and the battery near the chapel sent its bullets crashing through the houses, or booming up the valley towards Conroux’s column, which Inglis never ceased to vex.
The village and bridge of Sauroren and the straits beyond were soon covered with a pall of smoke, the musketry pealed frequent and loud, and the tumult and affray echoing from mountain to mountain filled all the valley. Byng with hard fighting carried Sauroren, fourteen hundred prisoners were made, and the two French divisions, being entirely broken, fled, partly up the valley towards Clausel’s other divisions, partly up the original position, to seek refuge with Foy, who remained on the summit a helpless spectator of this rout. He rallied the fugitives in great numbers, but had soon to look to himself, for his own skirmishers were now driven up the mountain by Cole’s men, and his left was infested by Picton’s detachments. Thus pressed, he fell back along the hills separating the valley of Zubiri from that of Lanz, and the woods enabled him to effect his retreat without much loss; yet he dared not descend into either valley, and thinking himself entirely cut off, sent advice to Soult and went over the Great Spine into the Alduides by the pass of Urtiaga. Clausel meanwhile had been driven up the valley of Lanz to Olague, where, being joined by La Martinière, he took a position; and Wellington, whose pursuit had been damped by hearing of Hill’s action, also halted.
The allies lost nineteen hundred men killed, wounded, or taken in this and Hill’s battle, and nearly twelve hundred were Portuguese, for the soldiers of that nation bore the brunt of both fights. On the French side the loss was enormous. Conroux’s and Maucune’s divisions were completely disorganized. Eight thousand men under Foy were entirely separated from the main body, two thousand at the lowest computation were killed or wounded, many were dispersed in the woods and ravines, and three thousand prisoners were taken. Soult’s fighting men were thus reduced to thirty-five thousand, of which fifteen thousand under Clausel and Reille were dispirited by defeat, and the whole in a critical situation, seeing that Hill’s force, increased to fifteen thousand men by the junction of Morillo and Campbell, was in their front at Eguaros, and thirty thousand were on their rear in the valley of Lanz; for Picton, finding no enemies in the valley of Zubiri, had joined Cole on the heights.
Wellington had sent some Spaniards to Marcalain when he first heard of Hill’s action, yet he was not then aware of the true state of affairs on that side, and his operations were founded on the notion that Soult was in retreat towards the Bastan. Hence he designed to follow closely and push his own left forward to support Graham on the Bidassoa; but he still underrated D’Erlon’s force, and thought La Martinière’s division had originally retreated up the Val de Zubiri to Roncesvalles, instead of crossing the intervening ridge to the Lanz valley; and as Foy’s column was numerous, and two divisions had been broken at Sauroren, he judged the force immediately under Soult to be very weak, and made dispositions accordingly. The sixth division and the 13th Light Dragoons were ordered to join Picton, the whole to move upon the Roncesvalles; Cole was called down into the valley of Lanz, and Hill was directed to press Soult, turning his right, yet still directing his own march upon Lanz: the seventh division was to let Hill cross its front, and then march for the pass of Doña Maria.
These arrangements show that Wellington expected Soult to rejoin Clausel, and make for the Bastan by the pass of Vellate. But the French marshal was so far advanced he could not return to Lanz; he was between two fires, and could only retreat into the valley of St. Estevan by the pass of Doña Maria; wherefore, calling up Clausel, and giving D’Erlon, whose divisions were in good order, the rear-guard, he commenced his march at midnight towards the pass. Mischief was thickening around him. Graham, on the British left, had twenty thousand men ready to move either against Villatte or into the valley of St. Estevan; and there remained on that side the light division, under Charles Alten, of whose operations it is time to speak.
That general had descended the mountain of Santa Cruz on the evening of the 28th, to gain the great road of Irurzun; but whether by orders from Graham, or in default of orders, the difficulty of communication being extreme in those wild regions, he commenced his movement very late, and darkness falling on his rear brigade while in march, the troops got dispersed in that frightful wilderness of woods and precipices. Many soldiers made faggot torches, waving them as signals, and, so moving, the lights served indeed to assist those who carried them, yet misled and bewildered others who saw them at a distance; for the heights and the ravines were alike studded with these small fires, and the soldiers calling to each other filled the whole region with their clamour. Thus they continued to rove and shout until morning showed the face of the mountain covered with scattered men and animals, who had not gained half a league of ground beyond their starting place, and it was many hours ere they could be collected.
Alten, now for three days separated from the army, sent mounted officers in various directions to obtain tidings, and at six o’clock in the evening renewed his march, but at Areysa halted without suffering fires to be lighted; for he knew nothing of the enemy and was fearful of discovering his situation. At night he moved again, and finally established his bivouacs near Lecumberri early on the 30th, having heard the noise of Hill’s battle at Buenza in the course of the day. The light division was thus brought into the immediate system of operations, and had Soult continued his march, after driving back Hill, it would have been in great danger. Now it was a new power thrown into Wellington’s hands at a critical moment, for Villatte, contrary to the intelligence received, had not advanced, and Soult was therefore completely isolated: he had indeed no resources save what his ability and courage could supply.
His single line of retreat by Doña Maria was secure only as far as San Estevan, and from that town he could march up the Bidassoa to the Bastan, to regain France by the Col de Maya; or down the same river towards Vera by Sumbilla and Yanzi, from both of which roads branching off to the right led over the mountains to Echallar: yet he might be intercepted on either side. The Col de Maya way was good, that down the Bidassoa was a long and terrible defile, so contracted about the bridges of Yanzi and Sumbilla that a few men only could march abreast. This then he had to dread. First, that Wellington by the pass of Vellate would reach the Bastan before him, and block the Maya passes. Second, that Graham would occupy the rocks of Yanzi and cut him off from Echallar. Then, confined to a narrow mountain-way leading from San Estevan to Zagaramurdi, and far too rugged for wounded men and baggage, he would be followed by Hill, and perhaps headed at Urdax by Wellington.
In this state, the first object being to get through Doña Maria, he commenced his retreat in the night of the 30th, while Wellington, still ignorant of the real state of affairs, halted in the valley of Lanz to let Hill pass his front and enter the Bastan. But early on the 31st, Soult’s real strength became known, and the seventh division was directed to aid Hill, while Wellington marched himself through the pass of Vellate, and sent Alten orders to cut in upon the French, intercepting their march where he could. Longa, who was with Graham, had instructions to seize the defiles at Yanzi, and aid the light division to block that way, while Graham was to hold all his corps in readiness for the same object.
