What did Castlereagh think of Wellington? Why? How did this affect Wellington?

Wellington so impressed Castlereagh that the thirty-seven-year-old soldier was soon a trusted confidant and advisor on one military scheme after another. One of those schemes included keeping an eye on Napoleon's activities. The first real chance Britain had to make a solid move against Napoleon came in 1808 when there was an uprising in Spain and Portugal against the French emperor. The event eventually became the Peninsular War. Wellington once again impressed Castlereagh with his ideas on protecting Portugal with naval power. The Peninsular War would last until 1814. Along the way, Wellington gained more fame and a number of prestigious titles.
