[348] D’Urban visited Ballasteros’s camp on the 14th and settled with him all the details of a joint march against Maransin (whom they wrongly supposed to be d’Aremberg, not knowing that the latter had returned to Seville with the cavalry). ‘If d’Aremberg takes the bait, and follows Ballasteros, he must be lost altogether; even if he halts at Xeres we ought to get hold of him,’ writes D’Urban in his diary. But Maransin fled on the morning of the 15th. [349] D’Urban’s diary under the 17th April. Ballasteros stayed behind in Estremadura, and the allied force in that province was strengthened by his 3,500 men. But this was not all: the Regency at Cadiz resolved to place a considerable army in this direction, their own city being more than amply garrisoned, and expeditions to the south being unpopular since the fiasco that followed Barrosa. On April 25th General Blake took the two divisions of Zayas and Lardizabal (both of which had fought at Barrosa), and landed with them at Ayamonte, the port in the mouth of the Guadiana. From thence he moved up along the Portuguese frontier, and joined Ballasteros near Xeres de los Caballeros about a fortnight later. Between them they had over 10,000 infantry and about 800 cavalry, but few guns, for Blake found it difficult to horse the batteries that he had brought with him, and left all save six pieces behind, at Ayamonte, to follow when they could procure teams. They had not rejoined him four weeks later, when the battle of Albuera was fought. The presence of Blake was not altogether an unmixed benefit, for he was independent of Castaños, who commanded the ‘5th Army’ or old Estremaduran force, and the two generals were ancient rivals and did not seem likely to co-operate with any cordiality. But if Soult was to make his appearance for the relief of Badajoz, it was as well that the Allies should be as strong as possible on the front by which he must attack.
