Next day, Massena moved forward with 5000 cavalry and 40,000 infantry, and Wellington made some alterations in his dispositions, so that his front now extended for a distance of some seven miles. By this new arrangement, the 7th Division (to which the 51st belonged) was placed on the extreme right, near the hill of Nava de Avel, opposite to which the French appeared to be massing in strength. On the morning of the 5th May Massena pushed on, and simultaneously attacked the village of Fuentes and the right of the British position. The 7th Division, outnumbered, were forced back, but the Light Division and the cavalry hastened to its support, and restored the fight. Wellington, now observing that his right was in imminent danger of being turned, ordered the 7th Division to draw in, and the Light Division covered the withdrawal in a magnificent manner. The enemy's strong force of cavalry made strenuous efforts to crush this portion of the line, and what immediately occurred is best described in the words of Napier. "The Light Division," he says, "was thrown into squares; the Seventh Division, which was more advanced, endeavoured to do the same, but the horsemen were too quick upon them, and some were cut down; the remainder stood firm, and the Chasseurs Britannique ranged behind a loose stone wall poured such a fire that the French recoiled and seemed bewildered." According to all accounts, the battle scene at this phase of the fight was a most picturesque one. The vast plain was covered with charging bodies of horsemen, who once and again endeavoured to break the squares, which, nothing daunted, met the onslaught, and leisurely retired. But the grandest sight of all on that memorable day was perhaps that presented by Norman Ramsay's two-horse artillery guns, which, hemmed in and cut off by the enemy's cavalry, saved themselves, not by their fire, but by cleaving their way at full gallop through the astonished French horsemen. This was, however, but one incident of many in a day of great deeds, and for a long while the issue of the fight hung in the balance. Failing to effect his purpose on the British right, Massena directed his attention to the capture of the village of Fuentes; but at this point also his troops were eventually beaten back, and at nightfall the British and French sentries, separated only by the breadth of the Duas Casas, agreed to take water from the river without molestation--a tacit agreement which always existed in Peninsular warfare between the veterans of the opposing armies.
