Sir Arthur Wellesley, having about ten thousand men under his command, sailed from Cork on the 12th of July, and leaving the fleet as soon as he had seen it clear of the coast, made sail in a frigate for Coruña, and arrived there on the 20th. There the Junta of Galicia informed him of the battle of Rio Seco; and that the French, being, in consequence, masters of the course of the Douro, were enabled to cut off the communication between that province and the country to the south and east. The French in Portugal they estimated at 15,000, of whom 12,000 were supposed to be at Lisbon; and he was told that the Portugueze troops at Porto amounted to 10,000, and that a Spanish corps of 2000 had begun their march for that city on the 15th, and were expected to arrive there about the 25th. Sir Arthur consulted with them concerning the immediate employment of his army. They explicitly stated that they were in no need of men, but wanted arms, ammunition, and money: ... this latter want was relieved by the arrival of £200,000 from England that very day. They strongly recommended him to employ his forces against the enemy in Portugal, because while that army remained unbroken the Spaniards could never make any simultaneous effort to drive the French out of the Peninsula; and they advised him to land in the north, that he might bring forward and avail himself of the Portugueze troops in that quarter.
Accordingly Sir Arthur sailed for Porto, ordering the fleet to follow him. He arrived there the 24th, and had a conference that night with the Bishop and the general officers. From them, and from Lieutenant-colonel Brown, who had previously joined them, he learnt that the regular Portugueze troops who had been collected amounted to 5000 men, and were posted at Coimbra; that there were about 1200 peasants in advance, and a corps of 2500 Portugueze and 300 Spanish infantry at Porto, besides volunteers and peasants; but all were badly equipped and armed, the peasantry having only pikes. It was concerted that the 5000 should co-operate with him, and the remainder with the Spanish corps, then, so the Spaniards had informed him, on its way from Galicia; and that the peasantry should be employed, part in the blockade of Almeida, part in the defence of Tras os Montes, which province was supposed to be threatened by Bessieres, in consequence of his victory at Rio Seco. Sir Arthur stated, that he should want cattle for draught, and for the supply of his army; the Bishop took pen and ink, wrote down the number which would be required, and replied immediately that they were ready.
