His visit to Scotland had the effect of restoring his eyesight, and in May 1813, he rejoined the army at Frinada, on the frontiers of Portugal, bringing with him the insignia of the Order of the Garter to Lord Wellington. On 22May the British force quit Portugal and moved upon Vitoria in three divisions. The left wing, which was commanded by Sir Thomas Graham, had to cross three large rivers—the Douro, the Esla, and the Ebro—and had to force positions of great strength among the passes of the mountains, continually pressing round the right wing of the retiring French army. General Graham took a prominent part in the battle of Vitoria (21 June), when the French were beaten "before the town, in the town, about the town, and out of the town"; and, by carrying the villages of Gamarra and Abechuco at the point of the bayonet, he intercepted the retreat of the enemy by the high road to Bayonne, and compelled them to turn to that leading to Pampeluna.
