All the houses within 700 toises of the place were demolished, and the materials employed to strengthen the fortifications. The trees around the city were cut down. The greatest activity reigned on all hands; the women were employed in making clothes for the soldiers; the monks made cartridges: and all those not employed in labouring at the works, practised the use of arms.

Measures were likewise taken for the defence of the city, in case the enemy, which was scarcely to be doubted, should effect an entrance. Traverses were cut across the streets. The doors and windows on the ground-floor were strongly barricaded. Communications were made between the houses; and parapets were constructed on the roofs. Every householder had in his dwelling an ample store of provisions, to enable him to continue his resistance when the enemy should gain possession of the streets. Thus prepared, the Zaragozans awaited the approach of the besiegers.

In the meanwhile, the corps of Marshal Moncey, which had been ordered to blockade the city, remained at Alagon, collecting materials, and awaiting the arrival of his heavy artillery from Pamplona. On the 19th of December it was joined by the corps of Mortier, and on the 20th the united army appeared before Zaragoza. It consisted of about 35,000 infantry, and was accompanied by a battering train of sixty pieces. A corps of cavalry was stationed at Fuentes, to keep the surrounding country in a state of subjection.

The city was approached on both sides of the Ebro. Gazan’s division, having passed the river at Tauste, marched, by the road of Castejon, to Cuera and Villa Nuevo. That of Suchet took post on the right of the Ebro, near a convent, about a league distant from Zaragoza, after driving in the Spanish outposts.

During the night, the enemy erected a battery, which commanded the Torrero, and, in the morning, opened fire on the fort. Unfortunately, a quantity of ammunition was blown up, by the bursting of a shell, which occasioned considerable disorder in the garrison. The French took advantage of this. A column crossed the canal by an aqueduct, of which on the evening before, they had become masters, and entering the fort by the gorge, succeeded in maintaining the place against the efforts of the garrison. At the same time, a brigade of Morlot’s division advanced up the ravine of the Huerba, and, passing the canal under the aqueduct on which it crosses that river, gained possession of a work commanding the sluices of the canal. Two guns were taken in this work. Three guns and 100 prisoners in the fort. General St. Mark succeeded in withdrawing the rest of the garrison.

On the 22nd, General Gazan advanced against the suburb, on the left of the river. He was encountered by about 4000 of the garrison, posted in the woods and gardens, from which, after a warm contest, he succeeded in dislodging them. Gazan then attempted to carry the suburb by a coup-de-main. In this he failed. Repulsed in all his efforts, after a long and fruitless contention, he at length withdrew, pursued by the garrison, and with the loss of near 1000 men. The chief loss of the besieged consisted of a corps of Swiss, almost all of whom were killed or taken prisoners in a large building considerably in advance of the suburb.

For several days all was quiet. The enemy were now aware that it was necessary to make a regular investment of the place; and the works in all quarters, were pushed on with vigour. The besieged on their part endeavoured, by incessant labour, to complete the works of defence; batteries were constructed, to enfilade the principal approaches—the magazines were rendered bomb-proof—every outlet was palisaded and traversed; and, thus prepared, they waited with calm fortitude for the approaching struggle.

On the 30th, Marshal Moncey addressed a letter to Palafox, summoning him to surrender the city, now entirely invested, and to spare the effusion of blood which must necessarily follow any further attempt at hopeless resistance. Moncey likewise informed him that Madrid had fallen; and that Napoleon, at the head of a great army, was then in the act of chasing the English to their ships.

To this Palafox replied, that if Madrid had fallen, Madrid had been sold. The works of Zaragoza were yet entire; but, were they levelled with the ground, the people and the garrison would rather be buried in the ruins of their city, than disgraced by surrender.

In the meanwhile, General Gazan succeeded in effecting the blockade of the suburb.
