This was the reason why Wellington departed from Madrid on August 31st, and marched with the 1st, 5th and 7th Divisions, Pack’s and Bradford’s Portuguese, and Bock’s and Ponsonby’s dragoons--21,000 sabres and bayonets--to join Clinton, and thrust back Clausel to the North, before he should have leisure to do further mischief. There was, as he conceived, just time enough to inflict a sharp check on the Army of Portugal before the danger from the side of Valencia would become pressing. It must be pushed out of the way, disabled again if possible, and then he would return to Madrid for the greater game, leaving as small a containing force as possible in front of the Northern army. He summed up his plan in a confidential letter in the following terms: ‘All the world [the French world] seems to be intending to mass itself in Valencia; while I am waiting for their plans to develop, for General Hill to march up from Estremadura, and for the Spanish armies to get together, I shall hunt away the elements of Marmont’s [i. e. Clausel’s] army from the Douro. I shall push them as far off as I can, I shall try to establish proper co-operation between the Anglo-Portuguese detachment which I must leave on this side and the Galician Army, and so I shall assure my left flank, when I shall be engaged on the Valencian side[3].’ Here then, we have a time-problem set. Will it be possible to deal handsomely with the Army of Portugal, to put it completely out of power to do harm, before Soult shall have reached Valencia, reorganized his army, and joined King Joseph in what Wellington considered the inevitable scheme of a march on Madrid? The British general judged that there would be sufficient time--and probably there might have been, if everything had worked out in the best possible way. But he was quite conscious that events might prove perverse--and he shuddered at the thought--as he wrote to his brother in Cadiz.
