But if a siege was coming, there was one position just outside the town which was clearly destined to play a chief part in it. Just across the Huerba lay a broad flat-topped hill, the Monte Torrero, which rose to the height of 180 feet, and overlooked all the south side of the place. It was such a splendid vantage-ground for siege-batteries, that the defenders were bound to hold it, lest it should fall into the power of the French. It should have been crowned by a strong detached fort, or even by an entrenched camp. But Palafox in the short time at his disposal had only been able to throw up a couple of open batteries upon it, and to loophole the extensive magazines and workshops of the Canal of Aragon, which were scattered over the summit of the hill, while the canal itself flowed, as a sort of outer defence, around its further foot. Saragossa had two other outlying defences: the one was the Aljafferia, an old square castle with four towers at its corners, which had been the abode of Moorish emirs, and of Aragonese kings, but now served as the prison of the Inquisition. It lay a couple of hundred yards outside the western gate (Puerto del Portillo) of the city. It was a solid brick structure, but quite unsuited to resist a serious artillery attack. The second outwork was the suburb of San Lazaro beyond the Ebro: it was connected with Saragossa by a new and handsome bridge, known as the ‘Puente de Piedra,’ or ‘Stone Bridge.’ Cannon were mounted at its southern end so as to sweep its whole length. On June 15, Lefebvre-Desnouettes appeared before the city, driving before him some Spanish outposts which he had met upon the way. He resolved at once to carry the place by storm, a task which, considering the weakness of its walls, did not seem impossible, and all the more so because the gates stood open, each defended only by an earthwork containing two or three guns. The French general, neglecting the Monte Torrero and its commanding slopes, attacked only the western front between the gate of Portillo, near the Ebro, and the gate of Santa Engracia, close to the banks of the Huerba. His French brigade assailed the northern and his Polish regiment the southern half of this long line of walls and buildings. His two field-batteries were run up into the fighting line, to batter the earthworks and to reply to the Spanish guns. The only reserve which he kept in hand consisted of his brigade of cavalry. The resistance offered to Lefebvre was of the most irregular sort: Palafox himself was not present, and his second-in-command, Bustamante, seems to have done little in the way of issuing orders. The 6,000 half-trained levies which had fought at Alagon had not recovered their organization, and were hopelessly mixed in the line of defence with 4,000 or 5,000 armed citizens of all ages and classes who had gone to the walls, each parish under the charge of two or three local leaders, who paid little obedience to the commands of the regular officers.
