When the siege was resumed, St. Cyr withdrew the French posts from Palau and Monte Livio, leaving the way apparently open on that side, for the return of Garcia Conde, who, deceived by this wile came out at daybreak on the 3d of September, with fifteen hundred men and the beasts of burthen. Halting, for a little time, just beyond the gate, he examined the country in front with his glass; every thing appeared favourable and his troops were beginning to move forward, when the noise of drums beating to arms gave notice that an ambuscade was placed behind Palau. St. Cyr had, indeed, posted a brigade there in the hope of surprising the Spaniards, but the French forgetting the ambush, were performing the regular service of the camp at day-light, and a cry of astonishment burst from the Spanish column as it hastily retreated again into the town. Baffled by this ridiculous mistake, and concluding that the next attempt would be by Castellar and La Bispal, St. Cyr placed Mazzuchelli’s brigade (the same that had been behind Palau) in the valley of the Oña in such a manner that it could fall upon Conde’s rear when the latter should again come forth. He also put a battalion on the hills in a position to head the Spanish column, and drive it back either upon Mazzuchelli’s brigade or upon La Bispal, where he also posted three battalions and a squadron of Pino’s division. The 4th of September one thousand infantry, five hundred cavalry, and eleven hundred mules again came out of Gerona, and ascending the heights in which the fort of the Capuchin was situated, pushed in single files along a by-path, leading to Castellar da Selva. Mazzuchelli saw them plainly, but did not attack, waiting for the fire of the battalion ahead, and that battalion did not fire because Mazzuchelli did not attack, and it was supposed the Spaniards were part of his brigade. Garcia Conde quickly perceived their double error, and with great readiness filing off to his left, turned the right of the battalion in his front, and gained Castellar without hurt, although the French in Monjouic observing all that passed, played their guns upon the rear of his column. Being informed by the peasants at Castellar, that troops were also waiting for him at La Bispal, he made for Caza de Selva, and General Pino having notice of his approach, directed two battalions to seize the summit of a ridge which crossed the Spanish line of march, but the battalions took a wrong direction; the Spaniards moved steadily on, and although their rear was attacked by Pino’s personal escort, and that fifty men and some mules were captured, the main body escaped with honour.
