Three batteries of artillery had been brought up close to the Serra Convent, and now that there was no longer need of concealment these were brought forward, and--as the French issued from the town and hurried towards the post held by the two companies that had crossed--opened a heavy fire upon them. The French pushed on gallantly in spite of this fire and the musketry of the soldiers, but the wall of the convent was strong, more boats had been obtained, and every minute added to the number of the defenders. The attack was, nevertheless, obstinately continued. The French artillery endeavoured to blow in the gate, and for a time the position of the defenders was serious, but the enemy's troops were now evacuating the lower part of the town, and immediately they did so the inhabitants brought boats over, and a brigade under Sherwood crossed there. In the meantime General Murray had been sent with the German division to effect a passage of the river two miles farther up. Soult's orders to take possession of all the boats had been neglected, and it was not long before Murray crossed with his force. The confusion in the French line of retreat was now terrible. A battery of artillery, who brought up the rear, were smitten by the fire of Sherwood's men; many were killed, and the rest cut their traces and galloped on to join the retreating army. Sherwood's men pressed these in the rear, the infantry on the roof of the Seminary poured their fire on the retiring masses, and the guns on the Serra rock swept the long line. Had Murray now fallen upon the disordered crowd their discomfiture would have been complete, but he held his force inactive, afraid that the French might turn upon him and drive him into the river. General Stewart and Major Harvey, furious at his inactivity, charged the French at the head of two squadrons of cavalry only, dashed through the enemy's column, unhorsed General Laborde and wounded General Foy. Receiving, however, no support whatever from Murray, the gallant little band of cavalry were forced to fight their way back with loss. Thus, as Franceschi had been saved from destruction from an error as to the road, Soult was saved the loss of this army by Murray's timidity, and in both cases Sir Arthur's masterly plans failed in attaining the complete success they deserved.
