The 9th Corps, it will be remembered, was a promiscuous assembly of some twenty newly-raised fourth battalions, belonging to the regiments which were already in Spain. Eleven were fractions of corps serving in Soult’s Army of Andalusia, five of regiments of Ney’s 6th Corps, the rest of units under Reynier’s and Junot’s command. Drouet had been originally ordered to do no more than conduct these battalions, which were little better than a mass of drafts, to join the regiments to which they belonged. They were divided into two provisional divisions under Generals Conroux and Claparéde. Thrust, as it were, into Spain without any regular organization, destitute of battalion transport, and with an improvised and insufficient staff, they had made very slow progress since they crossed the Pyrenees, mainly owing to difficulties of commissariat. When Foy passed Salamanca on November 10th, the head of Claparéde’s division had only just entered that city; the tail of the corps was struggling up from Valladolid and Burgos. It is not surprising, therefore, to find that Claparéde only reached the neighbourhood of Almeida on the 15th of November, and that Drouet had not concentrated his whole force at that place till December 14th. He had about 16,000 men, having left three of his own battalions to garrison Ciudad Rodrigo, and picked up instead the remains of Gardanne’s column, which had retreated on to the Spanish frontier in such disorder at the end of the preceding month[24]. This detachment, by reason of its losses during its disastrous flight, had been reduced to about 1,400 men fit for service--about the same number that Drouet had left behind him from his own corps. Drouet was acting under stringent orders from the Emperor to move forward at the earliest possible moment[25], and open up communication with Masséna. His original instructions had been to go no further forward than Almeida himself, but to send a column under Gardanne, 6,000 strong, to clear and keep open the way to the Tagus. The march and failure of Gardanne have been already related, and Drouet saw that to carry out the Emperor’s orders he must use a larger force. At the same time his dispatches told him that he must at all costs keep in touch with Almeida, and not merely join Masséna and allow himself to be cut off from Spain[26]. [24] See vol. iii. p. 481.
