latter was far more binding, since Portugal had placed herself entirely in the hands of her allies, had put her army at their disposal, and had contributed all her resources to the common cause, while the Spanish Junta had shown a jealous and suspicious spirit, had refused to show confidence in Great Britain, and had persisted in carrying out a military policy of its own, which led to a consistent series of disasters; (4) the Portuguese army, though its fighting power was not as yet ascertained, could be at least relied upon for obedience; experience had shown that the promises of the Spaniards could not be trusted, and that any campaign undertaken in their company might be wrecked by some incalculable piece of slackness or miscalculation[111]. [111] Wellington’s arguments must be culled from his various dispatches to Lord Liverpool and other ministers in November and December 1809. For the first of the motives quoted above see Wellington to Liverpool Dec. 9. ‘The object in occupying this proposed position [in Beira] is to be at the point of the defence of Portugal, to divert the attention of the French from the South of Spain, when they shall receive their reinforcements, and thus to give time to the Spanish Government to repair their losses.... It is absolutely necessary to cross the Tagus immediately, as it may be depended upon that the enemy’s first effort, after receiving his reinforcements, will be upon the troops to the North of the Tagus.’ Very much the same opinion is expressed in the earlier dispatch to Lord Liverpool of November 14. Expressions of Wellington’s conviction that it was impossible to co-operate with the Junta or the Spanish generals may be found _passim_ in all his confidential letters. See for example that to Sir J. Anstruther, pp. 386-8 of _Supplementary Dispatches_, vol. vi.
