At daybreak on June 21 Wellington's immediate right under Hill moved forwards and slowly crossed the Zadorra just below the defile of Puebla. There was no occasion for haste, rather it was expedient to be leisurely, so as to give time for Graham to accomplish his much longer march. Then a brigade of Spanish infantry was sent to scale the heights which form the eastern side of the defile, and push along them so as to threaten to turn the French left. The remainder of the right wing passed through the defile and attacked the French left in front. Meanwhile Wellington with his centre had made his way through and over the hills separating the Bayas from the Zadorra, part by the gap of Subijana de Morillos, so as to converge on Hill's force, part some distance further to the northwards. By this time it was one o'clock, and the distant sound of cannonading told that Graham was already engaged. The French main army began to retreat, pressed steadily in front by Wellington, till they were driven back to within a mile of Vittoria. By this time Graham, who had considerably larger forces than those immediately opposed to him, had obtained command of the royal road. Carrying out on a small scale in action the same idea which had inspired Wellington's movements on the large scale, he had pushed forwards his left, winning possession of the village of Gamarra Mayor on Reille's extreme right. The French here held their ground with admirable tenacity, and Graham could seize neither the bridge at Gamarra, nor that directly in his front by which the Bilbao road enters Vittoria, though his guns could sweep the great road towards France. Reille thus saved the French army from annihilation: if he had been driven over the Zadorra a comparatively small part would have been able to escape at all. Thanks to him, the bulk of the soldiers were able to retire by the Pampeluna road; but it could scarcely be called an army. The losses in the battle, or rather in the pair of simultaneous battles, had not been exceptional, and had been tolerably equal, about 6000 killed and wounded on each side; but nothing escaped except the men. To quote the words of a French officer who took part in the action: "They lost all their equipages, all their guns, all their treasure, all their stores, all their papers, so that no man could prove how much pay was due to him: generals and soldiers alike were reduced to the clothes on their backs, and most of them were barefoot."
