No one saw more clearly than Napoleon the need for the reduction of Gerona: as early as January he had issued orders both to St. Cyr and to Reille to prepare for the enterprise. But St. Cyr was now out of touch, and Reille was far too weak in the early spring to dream of any such an adventure: he had been left no more than seven depleted battalions to maintain his hold on Northern Catalonia, when St. Cyr took the rest of the army across the hills to Barcelona. The Emperor was not slow to realize that the 7th Corps must be reinforced on a large scale. He did so by sending thither in the spring of 1809 a brigade of Berg troops (four battalions), the regiment of Würzburg (two battalions), and a division (seven battalions) of Westphalians: it will be noted that now, as always, he was most chary of drafting native French troops to Catalonia, and always fed the war in that direction with auxiliaries in whose fate he was little interested: the campaign in eastern Spain was, after all, but a side issue in the main struggle[17]. When these reinforcements had arrived Reille began to collect material at Bascara on the Fluvia, to which siege-guns laboriously dragged across the Pyrenees were added: several companies of heavy artillery and sappers were brought up from France.

St. Cyr meanwhile, four weeks after his retreat from the plain of Tarragona, moved on to Vich upon April 18, with the divisions of Souham, Pino, Lecchi, and Chabot, leaving Duhesme with his original French division, which had held Barcelona since the outbreak of the war, in charge of his base of operations. His departure was partly designed to spare the stores of Barcelona, where the pinch of famine was beginning to be felt; for he intended to subsist his army on the upland plain of Vich, a rich corn-bearing district hitherto untouched by the war. But a few days after he had marched forth Barcelona was freed from privation, by the lucky arrival of a squadron of victuallers from Toulon, convoyed by Admiral Cosmao, which had put to sea in a storm and eluded the British blockading squadron (April 27). The position of Vich, however, had been chosen by St. Cyr not only for reasons of supply, but because the place was happily situated for covering the projected siege of Gerona against any interruption by Blake. If the Spanish commander-in-chief brought up the wrecks of the old Catalan army from Tarragona, with his Valencian levies added, he would almost certainly take the inland road by Manresa and Vich, since the coast-road was practically barred to him by the French occupation of Barcelona. As a matter of fact the commencement of the leaguer of Gerona was not vexed by any such interruption, for Blake had his eyes fixed on Saragossa in May and June, and was so far from dreaming of an assault on St. Cyr, that he drew off part of
