On the whole Wellesley thought it would be best to make the first onslaught on Soult. ‘I should prefer an attack on Victor,’ he wrote, two days after landing, ‘in concert with Cuesta, if Soult were not in possession of a fertile province of this kingdom, and of the favourite town of Oporto, of which it is most desirable to deprive him. Any operation upon Victor, connected with Cuesta’s movements, would require time to concert, which may as well be employed in dislodging Soult from the north of Portugal, before bringing the British army to the eastern frontier[349].... I intend to move upon Soult, as soon as I can make some arrangement, on which I can depend, for the defence of the Tagus, to impede or delay Victor’s progress, in case he should come on while I am absent.’ ‘I think it probable,’ he wrote on the same day but in another letter, ‘that Soult will not remain in Portugal when I pass the Mondego: if he does, I shall attack him. If he should retire, I am convinced that it would be most advantageous for the common cause that we should remain on the defensive in the North of Portugal, and act vigorously in co-operation with Cuesta against Victor[350].’ [349] Wellesley to Castlereagh, from Lisbon, April 24. I have ventured to substitute ‘before bringing’ in the last sentence for the unmeaning ‘and to bring’ which is clearly a _lapsus calami_. [350] Wellesley (to Mr. Frere, at Seville) from Lisbon, April 24. In many sentences this dispatch is only a repetition of that to Castlereagh. But in others Sir Arthur makes his meaning more clear, by a more detailed explanation. Further forward it was impossible to look: a blow at Soult, followed by another at Victor, was all that could at present be contemplated. Wellesley was directed, by the formal instructions which he had received from Castlereagh, to do all that was possible to clear Portugal and the frontier provinces of Spain from the enemy, but not to strike deep into the Peninsula till he should have received permission from home to do so. Nevertheless he had devoted some thought to the remoter possibilities of the situation. If Portugal were preserved, and Soult and Victor beaten off, more ambitious combinations might become possible. He expressed his conviction that the French occupation of Spain would only be endangered when a very large force, acting in unison under the guidance of a single mind, should be brought together. The co-operation of the English army and that of Cuesta ‘might be the groundwork of further measures of the same and a more extended description[351].’ He was under no delusions as to the easiness of the task before him: he did not hurry on in thought, to dream of the expulsion of the French from the Peninsula as a goal already in sight. But he believed that he and his army ‘might be highly useful to the Spaniards and might eventually decide the contest[352].’ [351] Wellesley to Frere, Lisbon, April 24, 1809.
