While Sabijana was repeatedly assaulted, the light division was formed in close columns under cover of some broken ground, and at a short distance from the river. The hussar brigade, dismounted, were on the left; and the fourth division in position on the right, waiting the signal for advancing. The heavy cavalry formed a reserve to the centre, in event of its requiring support before the third and seventh divisions had come up; and the first and fifth, with a Spanish and Portuguese corps, were detached to occupy the road to San Sebastian, and thus intercept the enemy’s retreat. Presently, an opening cannonade upon the left announced that Sir Thomas Graham was engaged, and Lord Dalhousie notified his arrival with the third and seventh divisions at Mendonza. The moment for a grand movement had come--Lord Wellington saw and seized the crisis of the day, and ordered a general attack on the whole extent of the French position. The light division moved forward under cover of a thicket, and placed itself opposite the enemy’s right centre, about two hundred paces from the bridge of Villoses--and on the arrival of Lord Dalhousie, the signal was given to advance. At this critical moment an intelligent Spaniard opportunely came up, and announced that one of the bridges was undefended. The mistake was quickly seized upon. A brigade, led by the first rifles, crossed it at a run--and, without any loss, established itself in a deep ravine, where it was completely protected from the enemy’s cannonade. Nothing could be more beautiful than the operations which followed. The light division carried the bridge of Nanclaus, and the fourth that of Tres Puentes; the divisions of Picton and Dalhousie followed, and the battle became general. The passage of the river--the movement of glittering masses from right to left, far as the eye could range-- the deafening roar of cannon--the sustained fusilade of infantry-- all was grand and imposing; while the English cavalry, displayed in glorious sunshine and formed in line to support the columns, completed a spectacle, grand and magnificent beyond description.
