A few days before the arrival of marshal Lasnes, the besieged being exceedingly galled by the fire from a mortar-battery, situated at some distance behind the second parallel of the central attack, eighty volunteers, under the command of Don Mariano Galindo, endeavoured to silence it. They surprised and bayonetted the guard in the nearest trenches, and passing on briskly to the battery, entered it, and were proceeding to spike the artillery, when unfortunately the reserve of the French arrived, and, the alarm being given, the guards of the first trenches also assembled in the rear of this gallant band, intercepting all retreat. Thus surrounded, Galindo, fighting bravely, was wounded and taken, and the greatest part of his comrades perished with as much honour as simple soldiers can attain. The armed vessels in the river now made an attempt to flank the works raised against the castle of Aljaferia, but the French batteries forced them to drop down the stream again; and between the nights of the 21st and the 26th of January the besiegers’ works being carried across the Huerba, the third parallels of the real attacks were completed. The oil manufactory and some other advantageous posts, on the left bank of the above-named river, were also taken possession of and included in the works, and at the false attack a second parallel was commenced at the distance of a hundred and fifty yards from the castle of Aljaferia; but these advantages were not obtained without loss. The Spaniards made sallies, in one of which they spiked two guns and burnt a French post on the right. The besiegers’ batteries had, however, broken the wall of the town in several places. Two practicable breaches were made nearly fronting the convent of San Joseph; a third was commenced in the convent of Saint Augustin, facing the oil manufactory. The convent of San Engracia was laid completely open to an assault; and, on the 29th, at twelve o’clock, the whole army being under arms, four chosen columns rushed out of the trenches, and burst upon the ruined works of Zaragoza. On the right, the assailants twice stormed an isolated stone house that defended the breach of Saint Augustin, and twice they were repulsed, and finally driven back with loss. In the centre, the attacking column, regardless of two small mines that exploded at the foot of the walls, carried the breach fronting the oil manufactory, and then endeavoured to break into the town; but the Spaniards retrenched within the place, opened such a fire of grape and musquetry that the French were content to establish themselves on the summit of the breach, and to connect their lodgement with the trenches by new works.
