But before continuing the advance in this direction it was necessary to carry the fort of Our Lady of the Pillar, the other great outwork of the southern front of Saragossa. The main attention of the besiegers was directed against this point from the twelfth to the fifteenth, and their sapping gradually took them to within a few yards of the counterscarp. The Spanish fire had been easily subdued, and a practicable breach established. On the night of the fifteenth-sixteenth the fort was stormed by the Poles of the 1st regiment of the Vistula. They met with little or no resistance, the greater part of the garrison having withdrawn when the assault was seen to be imminent. A mine under the glacis exploded, but failed to do any harm: another, better laid, destroyed the bridge over the Huerba, behind the fort, when the work was seen to be in the power of the assailants. Lacoste reported to Junot that the Poles lost only one killed and two wounded--an incredibly small casualty list[128]. [128] Lacoste to Junot, Jan. 16, in Belmas, ii. 378. The fall of the fort of the Pillar gave the French complete possession of all the ground to the south of the Huerba, and left them free to attack the _enceinte_ of the city, which had now lost all its outer works save the Aljafferia: in front of that castle the ‘false attack’ made little progress, for the besiegers did not press in close, and contented themselves with battering the old mediaeval fortress from a distance. On that part of the line of investment nothing of importance was to happen. SECTION XI: CHAPTER II SIEGE OF SARAGOSSA: THE FRENCH WITHIN THE WALLS: THE STREET-FIGHTING: THE SURRENDER Lacoste’s first care, when the Pillar and San José had both fallen into his hands, was to connect the two works by his ‘third parallel,’ which was drawn from one to the other just above the edge of the ravine of the Huerba. In order to assail the walls of the city that stream had to be crossed, a task of some difficulty, for its bed was searched by the great batteries at Santa Engracia along the whole front between the two captured forts, while north of San José the ‘Palafox Battery’ near the Porta Quemada completely overlooked the lower and broader part of the river bed. The Spaniards kept up a fast and furious fire upon the lost works, with the object of preventing the besiegers from moving forward from them, or constructing fresh batteries among their ruins. In this they were not successful: the French, burrowing deep among the débris, successfully covered themselves, and suffered little.
