When this route was adopted it was anticipated that the different divisions of the British army would be able to unite at, or near, Valladolid. But the advance of the French rendered this impossible, and Hope ultimately joined Moore at Salamanca on December 4. Baird suffered from even more vexatious delays. Though the greater part of his convoy had arrived at Coruña on October 13, the local junta would not permit them to land without express orders from the central junta at Aranjuez. Consequently the disembarkation did not begin till the 26th and was only finished on November 4. Transport and equipment were difficult to obtain, and on November 22 Baird was still only at Astorga. There exaggerated reports of the French advance induced him to halt, but by Moore's orders he continued his march. On the 28th the news of the defeat of Castaños at Tudela reached Moore at Salamanca. Co-operation with a Spanish army now appeared impossible, and even a junction with Baird seemed too hazardous to attempt. Moore therefore, ordered Baird to retire on Coruña and to proceed to Lisbon by sea, and, while waiting himself at Salamanca for Hope, made preparations for a retreat to Portugal. On December 5, the day after his junction with Hope, Moore determined to continue his advance. He had received news of the enthusiastic preparations for the defence of Madrid but did not know of its fall, and he considered that the Spanish enthusiasm justified some risk on the part of the British troops. He accordingly recalled Baird, whose infantry had retired to Villafranca, though his cavalry were still at Astorga. On the 9th came the news of the fall of Madrid, but Moore believed that an attack on the French lines of communication might still prove useful, and on the 11th the advance was renewed. Moore himself left Salamanca on the 13th. On the 12th he learned for the first time from some prisoners the true strength of the French army, 250,000 of all arms, and also discovered that the enemy were in complete ignorance of the position of his own army. Next day an intercepted despatch showed him that he might possibly be able to cut off Soult in an isolated position at Saldaña. Having at last effected a junction with Baird's corps on the 19th he reached Sahagun on the 21st, and was on the point of delivering his attack under favourable conditions, though his triumph must have been short-lived.
