Moreover, he must keep a force beyond the Segre, to block the _tête-du-pont_, and this force must be a large one, because the east was the quarter from which succours sent from Catalonia must certainly appear. The garrison, on the other hand, was quite adequate to man the works entrusted to it; the entry into the town of Perena’s Aragonese battalions had brought it up to a strength of over 8,000 men. The artillery were the weak point--there were only 350 trained men to man over 100 pieces. The Governor was Major-General Garcia Conde, who owed his promotion to his brilliant achievements at Gerona in the preceding September. Suchet’s 13,000 men were insufficient for a close and thorough investment of such a large space as that covered by the Lerida-Garden fortifications. He was forced to leave a considerable part of its southern front watched by cavalry posts alone. Of his total force, Musnier, with six battalions and the greater part of the cavalry--about 4,000 men in all, was beyond the river. Three battalions blocked the _tête-du-pont_, the rest formed a sort of covering force, destined to keep off the approach of enemies from the side of Catalonia. On the hither side of the Segre the three brigades of Habert, Buget, and Vergès were encamped facing the western and north-western fronts of Lerida. They counted only thirteen battalions, being weakened by 1,200 men who had been detached to garrison Monzon and Fraga. The communication between Musnier’s division and the rest of the army was by a flying bridge thrown across the Segre two miles above the town; it was guarded by a redoubt. The artillery park was placed at the village of San Rufo, opposite the north-western angle of the town, from which it is distant about 2,500 yards. It was evident from the first that this would be the point of attack selected by the French engineers. The army had barely taken up its position when, on April 19, rumours were spread abroad that O’Donnell was on his way to relieve Lerida. They must have been pure guesses, for the Spanish general on that day was still at Tarragona and had made no movement. They were, however, sufficiently persistent to induce Suchet to take off Musnier’s covering corps, strengthened by three other battalions, on a mission of exploration, almost as far as Tarrega, on the Barcelona road. No Spanish force was met, nor could any information be extracted from the inhabitants. The absence of the troops on the left bank of the Segre was soon detected by Garcia Conde, who--to his great regret three days later--sent messengers to inform O’Donnell that the French lines to the east of the city were now almost unoccupied.
