No success was to be expected from another attack, yet he could not, being reinforced with eighteen thousand men, retire by the road he came without some dishonour; nor could he remain where he was, because his supplies of provisions and ammunition, derived from distant magazines by slow and small convoys, were unequal to the consumption. Two-thirds of the British troops, great part of the Portuguese and all the Spaniards, were, as he supposed, assembled in his front under Wellington, or on his right flank under Hill; and it was probable other reinforcements were on the march; wherefore he resolved to prolong his right with D’Erlon’s corps, and cautiously drawing off the rest of his army place the whole between the allies and the Bastan, in military connection with his reserve and closer to his frontier magazines. Thus posted he could combine all his forces in one operation to relieve San Sebastian, and profit from new combinations. In the evening of the 29th the second division of cavalry, which was in the valley of Zubiri, passed over to that of Lanz and joined D’Erlon, who was ordered to march early on the 30th by the cross road, leading on Marcalain, which Hill had followed to get out of that valley. During the night the first division of cavalry and La Martinière’s division of infantry, both on the extreme left of the French army, retired over the mountains to Eugui, in the upper part of the Zubiri valley, having orders to cross the separating ridge there and join D’Erlon in the valley of Lanz. The remainder of Reille’s wing moved by the crest of the position to Sauroren, being gradually to relieve Clausel’s troops, which were then to move up the Lanz valley, follow D’Erlon, and be followed in like manner by Reille: meanwhile Clausel detached two regiments to the ridges beyond the Lanz river, to cover his own march and open a military connection with D’Erlon, whose new line of operations was just beyond those heights. In the night Soult again heard, from deserters, that three divisions were to make an offensive movement next day by the Marcalain road on his right, and at daylight he was convinced the men spoke truly; because from the ridges held by Clausel beyond Sauroren he descried columns descending from Picton’s position and from above Oricain, while others were in movement apparently to turn Clausel’s right flank. These columns were Morillo’s Spaniards, Campbell’s Portuguese, and the seventh division, marching to adopt a new disposition, which shall be presently explained.
