In 1810, at Wellington's request, Picton was appointed to command a division in Spain. Wellington recalled that he had been recommended by
General Miranda, who considered him "extremely clever", but also did not trust him, because "he has so much vanity that if you sent him out to the
Caraccas or the West India Islands, he would attempt to become the prince of them". Wellington commented when he met Picton, For the remaining years of the Peninsular War, Picton was one of Wellington's principal subordinates. The commander-in-chief never reposed in him the confidence that he gave to
Beresford,
Hill and
Robert Craufurd but in the resolute, thorough and punctual execution of a well-defined task Picton had no superior in the army. His debut, owing partly to his naturally stern and now embittered temper, and partly to the difficult position in which he was placed, was unfortunate. On the
River Coa in July 1810 Craufurd's division became involved in an action, and Picton, his nearest neighbour, refused to support him, as Wellington's direct orders were to avoid an engagement. Shortly after this, however, at
Busaco, Picton succeeded in driving French forces across a ravine in considerable disorder. In the first operations of 1812 Picton and Craufurd, side by side, stormed the two breaches of
Ciudad Rodrigo. Both Craufurd and Picton's second in command, Major-General
Henry MacKinnon, were mortally wounded in the engagement. At
Badajoz, a month later, the successful storming of the fortress was due to his daring self-reliance and penetration in converting the secondary attack on the castle, delivered by the
3rd Division, into a real one. He was himself wounded in this terrible engagement, but would not leave the ramparts, and the day after, having recently inherited a fortune, he gave every survivor of his command a
guinea. His wound, and an attack of fever, compelled him to return to Britain to recoup his health, but he reappeared at the front in April 1813. While in Britain he was invested with the collar and badge of a
Knight of the Order of the Bath by the Prince Regent
George, and in June he was made a
lieutenant-general in the army. At this time, Picton purchased the
Iscoed estate in
Carmarthenshire, and was returned triumphantly as Member of Parliament for
Pembroke Boroughs at a by-election on 19 March 1813. At the
Battle of Vitoria, Picton led his division across a key bridge under heavy fire. According to Picton, the enemy responded by pummeling the 3rd with 40 to 50
cannon and a counter-attack on their right flank (which was still open because they had captured the bridge so quickly) causing the 3rd to lose 1,800 men (over one third of all Allied losses at the battle) as they held their ground. The conduct of the 3rd division under his leadership at Vittoria and in the engagements in the
Pyrenees raised his reputation as a resolute and skilful fighting general to a still higher point. Early in 1814 he was offered, but after consulting Wellington declined, the command of the British forces operating on the side of
Catalonia. On the break-up of the division the officers presented Picton with a valuable service of plate, and on 24 June 1814 he received for the seventh time the thanks of the
House of Commons for his great services. Somewhat to his disappointment he was not included amongst the generals who were raised to the peerage, but early in 1815 he was appointed
Knight Grand Cross of the Order of the Bath (GCB). ==Death==
