While the commander of the 3rd Corps was making steady progress with the conquest of Aragon, the fortunes of his colleague of the 7th Corps had been far more chequered. Indeed for the greater part of 1809 St. Cyr was brought to a complete standstill by the unexpected obstinacy of the gallant garrison of Gerona, who for no less than eight months kept the main body of the army of Catalonia detained in front of their walls. When last we dealt with the operations in this region we left St. Cyr victorious at the well-contested battle of Valls, after which he advanced into the plain of Tarragona, made some demonstrations against that fortress, but returned after a few weeks to Barcelona (March 18) without having made any serious attempt to turn his victory to practical account. This retreat after a brilliant success may be compared to Victor’s similar evacuation of Southern Estremadura after Medellin, and was brought about, in the main, by the same cause, want of supplies. For when he had consumed the resources of the newly-subdued district between Valls and Tarragona, St. Cyr had no means of providing his army with further subsistence. Barcelona, his base, could not feed him, for the city was itself on the edge of famine: it was still beset to north and west by the local miqueletes, who had returned to their old haunts when the main French army had gone off southward on the campaign of Valls. It was stringently blockaded on the sea side by the British Mediterranean fleet, and it could not draw food from France by land, because the high-road to Perpignan passed through the fortress of Gerona, which was still in Spanish hands. St. Cyr himself, it will be remembered, had only reached Barcelona by turning off on to side tracks through the mountain, and winning his way down to the shore by the hard-fought battle of Cardadeu. Till Gerona should fall, and the garrison of Barcelona be placed in direct communication with France, there was little use in making ambitious offensive movements against Tarragona or any other point in Southern or Central Catalonia. It was absolutely necessary to reduce Gerona, and so to bring the division left behind under Reille, in the Ampurdam and on the frontier of Roussillon, into free communication with the remainder of the 7th Corps. From the moment when St. Cyr passed the mountains during the winter Reille had been fighting out a petty campaign against the northern Catalans, which had no connexion whatever with his superior’s operations at Molins de Rey and Valls, and had little definite result of any kind.
