The captives walked from their prison but their chains hung upon them. The way was narrow, the multitude great, and the baggage, and wounded men borne on their comrades’ shoulders, filed with such long procession, that Clauzel’s divisions forming the rear-guard were still about San Estevan on the morning of the 1st of August, and scarcely had they marched a league of ground, when the skirmishers of the fourth division and the Spaniards thronging along the heights on the right flank opened a fire to which little reply could be made. The troops and baggage then got mixed with an extreme disorder, numbers of the former fled up the hills, and the commanding energy of Soult whose personal exertions were conspicuous could scarcely prevent a general dispersion. However prisoners and baggage fell at every step into the hands of the pursuers, the boldest were dismayed at the peril, and worse would have awaited them in front, if Wellington had been on other points well seconded by his subordinate generals. The head of the French column instead of taking the first road leading from Sumbilla to Echallar, had passed onward towards that leading from the bridge near Yanzi; the valley narrowed to a mere cleft in the rocks as they advanced, the Bidassoa was on their left, and there was a tributary torrent to cross, the bridge of which was defended by a battalion of Spanish Caçadores detached to that point from the heights of Vera by general Barceñas. The front was now as much disordered as the rear, and had Longa or Barceñas reinforced the Caçadores, those only of the French who being near Sumbilla could take the road from that place to Echallar would have escaped; but the Spanish generals kept aloof and D’Erlon won the defile. However Reille’s divisions were still to pass, and when they came up a new enemy had appeared. [Sidenote: August.] It will be remembered that the light division was directed to head the French army at San Estevan, or Sumbilla. This order was received on the evening of the 31st, and the division, repassing the defiles of the Zubieta, descended the deep valley of Lerins and reached Elgoriaga about mid-day on the 1st of August, having then marched twenty-four miles and being little more than a league from Estevan and about the same distance from Sumbilla. The movement of the French along the Bidassoa was soon discovered, but the division instead of moving on Sumbilla turned to the left, clambered up the great mountain of Santa Cruz and made for the bridge of Yanzi. The weather was exceedingly sultry, the mountain steep and hard to overcome, many men fell and died convulsed and frothing at the mouth, while others whose spirit and strength had never before been quelled, leaned on their muskets and muttered in sullen tones that they yielded for the first time.
