General Alten, who had now been separated for three days from the army, sent mounted officers in various directions to obtain tidings, and at six o’clock in the evening renewed his march. At Areysa he halted for some time without suffering fires to be lighted, for he knew nothing of the enemy and was fearful of discovering his situation, but at night he again moved and finally established his bivouacs near Lecumberri early on the 30th. The noise of Hill’s battle at Buenza was clearly heard in the course of the day, and the light division was thus again comprized in the immediate system of operations directed by Wellington in person. Had Soult continued his march upon Guipuscoa Alten would have been in great danger, but the French general being forced to retreat, the light division was a new power thrown into his opponent’s hands, the value of which will be seen by a reference to the peculiarity of the country through which the French general was now to move. It has been shewn that Foy cut off from the main army was driven towards the Alduides; that the French artillery and part of the cavalry were again on the Bidassoa, whence Villatte, contrary to the intelligence received by Soult, had not advanced, though he had skirmished with Longa, leaving the latter however in possession of heights above Lesaca. The troops under Soult’s immediate command were therefore completely isolated, and had no resources save what his ability and their own courage could supply. His single line of retreat by the pass of Doña Maria was secure as far as San Estevan, and from that town he could march up the Bidassoa to Elizondo and so gain France by the Col de Maya, or down the same river towards Vera by Sumbilla and Yanzi, from both of which places roads branching off to the right lead over the mountains to the passes of Echallar. There was also a third mountain-road leading direct from Estevan to Zagaramurdi and Urdax, but it was too steep and rugged for his wounded men and baggage.
