When Palafox had nearly completed his defences—the works on the Monte Torrero alone were still hopelessly behindhand—the French at last began to move up against him. On December 15 Marshal Mortier arrived at Tudela with the whole of the 5th Corps, veterans from the German garrisons who had not yet fired a shot in Spain. Their ranks were so full that though only two divisions, or twenty-eight battalions, formed the corps, it counted 21,000 bayonets. It had also a brigade of two regiments of hussars and chasseurs as corps-cavalry, with a strength of 1,500 sabres. The condition of Moncey’s 3rd Corps was much less satisfactory: it was mainly composed of relics of the original army of Spain—of the conscripts formed into provisional regiments with whom Napoleon had at first intended to conquer the Peninsula[114]. Its other troops, almost without exception, had taken part in the first siege of Saragossa under Verdier, a not very cheerful or inspiriting preparation for the second leaguer[115]. All the regiments had been thinned by severe sickness in the autumn; on October 10 they had already 7,741 men in hospital—far the largest figure shown by any of the French corps in Spain. The number had largely increased as the winter had drawn on, and the battalions had grown so weak that Moncey consolidated his four divisions into three during his halt at Alagon. The whole of the 4th division was distributed between the 2nd and 3rd, so as to bring the others up to a decent strength. On December 20 the thirty-eight battalions only made up 20,000 effective men for the siege, while more than 10,000 lay sick, some with the army, some in the base hospitals at Pampeluna. The health of the corps grew progressively worse in January, till at last in the middle days of the siege it had 15,000 men with the colours, and no less than 13,000 sick. We find the French generals complaining that one division of the 5th Corps was almost as strong and effective at this time as the whole combined force of the 3rd Corps[116]. Nevertheless these weary and fever-ridden troops had to take in charge the main part of the siege operations.

During the twenty days of his halt at Alagon, Moncey had employed his sappers and many of his infantry in the manufacture of gabions, wool-packs, and sandbags for the projected siege. He was continually receiving convoys of heavy artillery and ammunition from Pampeluna, and when Mortier came up on December 20, had a sufficiency of material collected for the commencement of the leaguer. The two marshals moved on together on that day, and marched eastward towards Saragossa, with the whole of their forces, save that four battalions were left to guard the camp and dépôts at Alagon, and three more at Tudela to keep open the Pampeluna road[117]. Gazan’s division crossed the Ebro opposite Tauste, to invest the transpontine suburb of Saragossa: the rest of the army kept to the right bank. Late in the evening both columns came in sight of the city. They mustered, after deducting the troops left behind, about 38,000 infantry, 3,500 cavalry, and 3,000 sappers and artillerymen. They had sixty siege-guns, over and above the eighty-four field-pieces belonging to the corps-artillery of Mortier and Moncey. The provision of artillery was copious—far more than the French had turned against many of the first-class fortresses of Germany. The Emperor was determined that Saragossa should be well battered, and had told off an extra proportion of engineers against the place, entrusting the general charge of the work to his aide-de-camp, General Lacoste, one of the most distinguished officers of the scientific corps.

When the reinvestment began, Gazan on the left bank established himself at Villanueva facing the suburb of San Lazaro. Mortier with Suchet’s division took post at San Lamberto opposite the western front of the city. Moncey, marching round the place, ranged Grandjean’s troops opposite the Monte Torrero, on the southern front of the defences, and Morlot further east near the mouth of the Huerba. His other division, that of Musnier, formed the central reserve, and guarded the artillery and the magazines. The Spaniards made no attempt to delay the completion of the investment, and kept quiet within their walls.

On the next morning the actual siege began. It was destined to last from December 20 to February 20, and may be divided into three well-marked sections. The first comprises the operations against the Spanish outworks, and terminates with the capture of the two great bridge-heads beyond the Huerba, the forts of San José and Our Lady of the Pillar: it lasted down to January 15. The second period includes the time during which the besiegers attacked and finally broke through the main enceinte of the city: it lasts from January 16 to January 27. The third section consists of the street-fighting, after the walls had been pierced, and ends with the fall of Saragossa on February 20.

Having reconnoitred the whole circuit of the Spanish defences on the very evening of their arrival before the city (December 20), Moncey and Mortier recognized that their first task must be to evict the Spaniards from the Monte Torrero, the one piece of dominating ground in the whole region of operations, and the spot from which Saragossa could be most effectively attacked. They were rejoiced to see that the broad hill was not protected by any continuous line of entrenchments, but was merely crowned by a large open redoubt, and defended in front by the two small bridge-heads on the Canal of Aragon. There was nothing to prevent an attempt to storm it by main force. This was to be made on the following morning: at the same time Gazan, on the left bank of the Ebro, was ordered to assault the suburb of San Lazaro. Here the marshals had underrated the strength of the Spanish position, which lay in such low ground and was so difficult to make out, that it presented to the observer from a distance an aspect of weakness that was far from the reality.

At eight on the morning of December 21 three French batteries, placed in favourable advanced positions, began to shell the redoubts on the Monte Torrero, with satisfactory results, as they dismounted some of the defender’s guns and exploded a small dépôt of reserve ammunition. An hour later the infantry came into action. Moncey had told off for the assault the divisions of Morlot and Grandjean, twenty battalions in all[118]. The former attacked the eastern front of the position, fording the canal and assailing the left-hand tête-de-pont on the Valencia road from the flank. The latter, which had passed the canal far outside the Spanish lines, and operated between it and the Huerba, attacked the south-western slopes of the hill. The defence was weak, and when a brigade of Grandjean’s men pushed in between the main redoubt on the crest and the Huerba, and took the western part of the Spanish line in the rear, the day was won. St. March’s battalions wavered all along the line; and as his reserves could not be induced to fall upon the French advance, the Valencian general withdrew his whole division into the city, abandoning the entire circuit of the Monte Torrero. The assailants captured seven guns—some of them disabled—in the three redoubts, and a standard of the 5th regiment of Murcia. They had only lost twenty killed and fifty wounded; the Spanish loss was also insignificant, considering the importance of the position that was at stake, and hardly any prisoners were taken[119]. The besiegers had now the power to bombard all the southern front of Saragossa, and dominated, from the slopes of the hill, the two advanced forts of San José and the Pillar. The leaders of the populace were strongly of opinion that the Valencian division had misbehaved, and they were not far wrong. Palafox had great difficulty in protecting St. March, whose personal conduct had been unimpeachable, from the wrath of the multitude, who wished to make him responsible for the weakness shown by his men[120]. The officer who lost the Monte Torrero in the first siege had been tried and shot[121]: St. March was lucky to escape even without a reprimand.

Meanwhile things had gone very differently at the other point where the French had tried to break down the outer defences of the city. The attack on the transpontine suburb of San Lazaro had been allotted to Gazan’s division. This was a very formidable force, 9,000 veterans of the best quality, who were bent on showing that they had not degenerated since they fought at Friedland. Owing to some slight mistake in the combination, Gazan only delivered his attack at one o’clock, two hours after the fighting on the Monte Torrero had ceased. His leading brigade, that of Guérin, six battalions strong, advanced against the northern and eastern fronts of the defences of the suburb. The Spaniards were holding as an outwork a large building called the Archbishop’s Tower (Torre del Arzobispo)[122] on the Villanueva road, 600 yards in front of the main line of entrenchments. This Gazan’s men carried at the first rush, killing or capturing 300 men of a Swiss battalion[123] which held it. They then pushed forward towards the inner fortifications, but were taken in flank by a heavy artillery fire from a redoubt which they had overlooked. This caused them to swerve towards the Barcelona road, where they got possession of a house close under the convent of Jesus, and threatened to cut off the garrison of that stronghold from the rest of the defenders of the suburb. At this moment a disgraceful panic seized the defenders of the San Lazaro convent, which lay directly in front of the assailants. They abandoned their post, and began to fly across the bridge into Saragossa. But Palafox came up in person with a reserve, and reoccupied the abandoned post. He then ordered a sortie against the buildings which the French had seized, and succeeded in driving them out and compelling them to retire into the open ground. Gazan doubted for a moment whether he should not send in his second brigade to renew the attack, for the six battalions that had borne the brunt of the first fighting had now fallen into complete disorder. But remembering that if this force failed to break into the suburb he had no reserves left, and that Palafox might bring over the bridge as many reinforcements as he chose, the French general resolved not to push the assault any further. He drew back and retired behind the Gallego stream, where he threw up entrenchments to cover himself, completely abandoning the offensive. For two or three days he did not dare to move, expecting to be attacked at any moment by the garrison. A sudden rise of the Ebro had cut off his communication with Moncey, and he could neither send the marshal an account of his check, nor get any orders from him[124]. His casualty-list was severe, thirty officers and 650 men killed and wounded: the Spaniards lost somewhat less, even including the 300 Swiss who were cut to pieces at the Archbishop’s Tower.

Palafox next morning issued a proclamation, extolling the valour shown in the defence of the suburb, treating the loss of the Monte Torrero as insignificant, and exaggerating the losses of the French. The Saragossans were rather encouraged than otherwise by the results of the day’s fighting, and spoke as if they had merely lost an outwork by the unsteadiness of St. March’s Valencians, while the main hostile attack had been repulsed. But it is clear that the capture of the dominating heights south of the city was an all-important gain to the French. Without the Monte Torrero they could never have pressed the siege home. As to the failure at the suburb, it came from attacking with headlong courage an entrenched position that had not been properly reconnoitred. The assault should never have been delivered without artillery preparation, and was a grave mistake. But clearly Mortier’s corps had yet to learn what the Spaniards were like, and to realize that to turn them out from behind walls and ditches was not the light task that they supposed.

Moncey so thoroughly miscalculated the general effect of the fighting upon the minds of the Spaniards, that next morning he sent in to Palafox a flag of truce, with an officer bearing a formal demand for the surrender of the city. ‘Madrid had fallen,’ he wrote: ‘Saragossa, invested on all sides, had not the force to resist two complete corps d’armée. He trusted that the Captain-General would spare the beautiful and wealthy capital of Aragon the horrors of a siege. Ample blood had already been shed, enough misfortunes already suffered by Spain.’ Palafox replied in the strain that might have been expected from him—‘The man who only wishes to die with honour in defence of his country cares nothing about his position: but, as a matter of fact, he found that his own was eminently favourable and encouraging. In the first siege he had held out for sixty-one days with a garrison far inferior to that now under his command. Was it likely that he would surrender, when he had as many troops as his besiegers? Looking at the results of the fighting on the previous day, when the assailants had suffered so severely in front of San Lazaro, he thought that he would be quite as well justified in proposing to the Marshal that the besieging army should surrender “to spare further effusion of blood,” as the latter had been to make such a proposition to him. If Madrid had fallen, Madrid must have been sold: but he begged for leave to doubt the truth of the rumour. Even at the worst Madrid was but a town, like any other. Its fate had no influence on Saragossa[125].’

Having received such an answer Moncey had only to set to work as fast as possible: his engineer-in-chief, General Lacoste, after making a thorough survey of the defences, pronounced in favour of choosing two fronts of attack, both starting on the Monte Torrero, and directed the one against the fort of San José and the other against that of the Pillar. These projecting works would have to be carried before any attempt could be made against the inner enceinte of the town. At the same time, Lacoste ordered a third attack, which he did not propose to press home, to be made on the castle of the Aljafferia, on the west side of the town. It was only intended to distract the attention of the Spaniards from the points of real danger. On the further bank of the Ebro, Gazan’s division was directed to move forward again, and to entrench itself across all the three roads, which issue from the suburb, and lead respectively to Lerida, Jaca, and Monzon. He was not to attack, but merely to blockade the northern exits of Saragossa. Communications with him were established by means of a bridge of boats and pontoons laid above the town. Gazan succeeded in shortening the front which he had to protect against sorties by letting the water of the Ebro into the low-lying fields along its banks, where it caused inundations on each of his flanks.
