All Ney’s troops were now concentrated for the siege, his outlying detachments in every direction having been relieved by Junot, who, at Masséna’s orders, brought down the 8th Corps from the Douro, placed a brigade to watch the Pass of Baños, left garrisons in Zamora and Toro, and advanced with the remainder of his troops to the line of the Agueda. Clausel’s division and St. Croix’s division of dragoons took post at San Felices, in immediate touch with Craufurd’s division. Solignac’s division lay a march and a half to the rear at Ledesma. San Felices is only 20, Ledesma is 40 miles from Ciudad Rodrigo, so that the 8th Corps, deducting the outlying brigades, could have joined Ney in two days. These distances were the governing factor in Wellington’s policy during the next month. Ney had 26,000 men of the 6th Corps and Montbrun’s 4,000 dragoons in front of Rodrigo; Junot could join him with 8,000 infantry and 1,800 cavalry in a day; a second day would bring up Solignac with 7,000 men more. Unless the 6th Corps could be surprised in its camps, and forced to fight before it received its reinforcements, there would be 47,000 French to face. Of their numbers Wellington was roughly aware; the figures sent in to him by Craufurd were accurate to within a few thousands[270], and estimated the enemy at 40,000 men. The Commander-in-Chief’s own calculation was even nearer the truth; early in May he reckoned Ney, with Loison’s division included, at 30,000 men, Junot and Kellermann at 30,000[271]. Early in June he made out that the two corps in his front, without Kellermann, amounted to 50,000 men[272], which was only 3,000 over the true total. He himself had at this moment only 18,000 British troops under his hand, and within striking distance. He had on April 27th, brought up his head quarters and the 1st Division to Celorico, and moved forward Picton and the 3rd Division to Pinhel, while Cole with the 4th remained at Guarda, and the Light Division was, as usual, facing the Agueda. The cavalry had also come up from the Mondego valley, and lay behind Almeida. Moreover, the five Portuguese brigades of Harvey, Collins, Pack, Coleman, and Alex. Campbell were ordered up to the front[273], and joined the army in the first days of May. Wellington thereupon incorporated Harvey’s brigade with the 3rd Division and Collins’s with the 4th, a system which he afterwards carried out with nearly all the Portuguese units. The whole of this mass of troops came to some 15,000 men[274]. These, with the British, making a total of 32,000 men, were all that Wellington could count upon, for he could not dare to move Hill’s 12,000 men from the south, where they were observing Reynier, nor to displace the small reserve, which lay at Abrantes and Thomar to guard against a possible French move along the Tagus by Castello Branco. Lisbon could not be left unprotected on this side, so long as Reynier lay between the Tagus and the Guadiana. [270] May 2, to Craufurd.
