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.
