Proceeded to Lecumberri, and afterwards moved into a wood, and encamped across the high road from Pamplona to Tolosa, about five leagues from both, supporting the left of General Hill's corps. [Sidenote: 31st] Marched to Loyza and encamped. [Sidenote: 1813 Aug. 1st] Soult having been worsted in all his attacks upon the British, was now in full retreat, having suffered very considerably in killed and wounded and prisoners. The Light Division made a forced march this day by Zubieta, along a mountain track on the left bank of the Bidasoa to the bridge of Yanzi (the distance about eight leagues), the greater part of the day under a burning sun, which sadly exhausted the men, but they cheered up on seeing the enemy, and made the attack with such real pluck that the latter was soon scampering across the bridge in the greatest hurry. This body of the enemy had merely occupied the bridge to protect the march of a column moving from Sumbilla. Our 1st and 3rd Battalions took possession of some houses near the bridge, and a tiralade was kept up until dark, the enemy's force being so formidable from the beginning, that it was not deemed advisable to push on. I lost this little affair by being ordered to remain at Loyza a sufficient time to try by court-martial, Sergeant Hayes. It came on dark before I got up to the Battalion. I got bewildered in the mountains and lost my way. The enemy's fires and ours appeared all round me before I gave up the attempt to find the Battalion, so I tied my horse to a tree, pulled him some leaves and loose grass, and lay down near him until daylight. My horse was ill, so the other two officers who had been on the court-martial were obliged to leave me before dark. [Sidenote: 2nd]
