A few days later, the head of Junot’s corps entered the province of Leon, and Loison was directed to move southward and join Ney at Salamanca. His place on the Esla and the Orbigo was taken by Clausel’s division of the 8th Corps. The newly arrived general executed another reconnaissance to the neighbourhood of Astorga, and on February 26 sent Santocildes a second summons, in the name of Junot. It received the same answer that had been given to Loison. It was clear that Astorga must be besieged, and that a battering train must be placed at the disposition of the force charged with the operation. But in the present state of the roads it would take some time to bring heavy guns to the front. Further operations had to be postponed. The 6th Corps, it may be remarked, had executed at the same time that Loison appeared in front of Astorga, a demonstration against Ciudad Rodrigo. King Joseph had written from Andalusia to beg Ney to threaten the place, while the news of the French victories in the south were still fresh, assuring him that the Spaniards were so cowed that a prompt surrender was probable. The Marshal, though doubting the wisdom of these optimistic views, concentrated his corps, advanced to San Felices, and on February 13 summoned Rodrigo. He got from General Herrasti, the governor, an answer as bold and confident as that which Loison received from Santocildes, and returned to Salamanca to disperse his troops in cantonments and ask for a battering-train[245]. His short and ineffective excursion to the banks of the Agueda had taken him in sight of the British outposts on the Spanish frontier, and had induced Wellington for a moment to think that the invasion of Portugal was at hand. It was impossible that he should have guessed that Ney’s advance had no better cause than King Joseph’s foolish confidence. Hence the withdrawal of the 6th Corps, after the vain summons of Ciudad Rodrigo, was as inexplicable as its advance. ‘I do not understand Ney’s movement,’ he wrote to his trusted subordinate, Robert Craufurd, ‘coupled as it is with the movement upon Badajoz from the south of Spain. The French are not strong enough for the two sieges at the same time, and I much doubt whether they are in a state to undertake one of them[246].’ The prompt retirement of Ney from before Ciudad Rodrigo, and of Mortier from before Badajoz, completely justified his conclusions within a day or two of the writing of his letter.
There was nothing for the French in the kingdom of Leon to do, save to await the arrival of the great battering-train which Napoleon had bestowed upon his Army of Portugal. It was far to the rear: on February 20 its head was only beginning to approach Burgos, and its tail had not quitted Bayonne. The reason of this tardiness was the want of draught animals at the southern dépôts of France. The equipment of the train and the artillery of the 8th Corps, and the other great reinforcements which had just passed the Pyrenees, had exhausted the available supplies of horses[247], and when the authorities at Bayonne had to place the ‘grand park’ on a war footing there was intolerable delay. Even when detachments of the park had started, they made slow progress in Spain, for the French horses died off rapidly in the bitter weather of the plateau of Old Castile, and it was almost impossible to replace them by requisition from the country-side. Junot, bold to the verge of rashness, and feverishly anxious to remake the reputation that he had lost at Vimiero, could not endure the delay. He sent to requisition Spanish guns from the governors of Burgos and Segovia, dispatched his own teams to draw them, and when he heard that a small train was procurable, ordered the 8th Corps towards Astorga on March 15, leaving the cannon to follow. The month’s delay in the investment had enabled Santocildes to fill up the supply of food and ammunition which had been so low in February; he had now got his fortress in as good state as was possible, considering the intrinsic weakness of its mediaeval walls, and had induced 3,000 of the 4,000 inhabitants to retire to Galicia.
On March 21 Clausel’s division invested Astorga, while Solignac’s came up to Leon and Benavente in support, and St. Croix’s division of dragoons took post in advance of La Baneza, to observe the Spanish forces in southern Galicia and the Portuguese of the Tras-os-Montes. Till the guns should arrive, there was nothing to be done save to choose the point of attack, prepare fascines and gabions, and open the first parallel, out of harm’s way from the small artillery of the garrison—none of it heavier than a 12-pounder. Valazé, Junot’s chief engineer, opined that the low-lying suburbs at the foot of the hill of Astorga might be neglected, and the newly entrenched Reteibia on the high ground masked by a false attack, while the projecting and unflanked north-west corner of the old walls of the city itself might be battered from the slopes below: here, as in all its circuit, the place had neither ditch nor glacis: there was simply the stout mediaeval wall, broken every 30 yards by a small square tower, which followed the sky-line of the plateau.
The first three weeks of the siege had an unusual character, since the French could build what works they pleased, but could not seriously batter Astorga with the sixteen field-guns of small calibre belonging to the division lying before the walls. The officer in temporary command of the artillery, Colonel Noël, contented himself with opening fire from various false attacks, from which the guns were repeatedly moved, in order to distract the attention of the enemy from the chosen front on the north-west, where the approaches were completed, and a great battery constructed, ready for the siege-guns when they should arrive. Meanwhile there was a good deal of infantry skirmishing in and about the lower suburbs, in whose outskirts the French ultimately established themselves, though they had no intention of pushing up to the walls either from Puerta del Rey or from San Andrés[248]. The garrison defended itself well, executed several vigorous sorties, and lost no post of importance, though the line of resistance in the suburbs was gradually thrust back. Santocildes received several encouraging messages from his chief Mahy, who announced that he was bringing up to the pass of Foncebadon, on the edge of the plain of Astorga, every man that Galicia could furnish. But even when the Captain-General had brought his reserves from Lugo to join Garcia’s division, they had only 5,000 bayonets. To hold them off, Junot sent Clausel’s division to the outposts, and replaced it in the trenches by Solignac’s and one brigade of Lagrange’s. Mahy, in face of such an accumulation of men, was absolutely helpless. Echevarria, with his weak brigade from Puebla de Senabria, had pushed a little forward, to give moral support to Mahy. He was surprised and routed near Alcanizas on April 10, by St. Croix’s dragoons.
On the 15th the siege-train arrived from Valladolid; it was small[249], but sufficient against an enemy so miserably provided with guns as Santocildes. Junot himself came up on the 17th to watch the effect of the attack. It was instant and overpowering. When once the artillery had been placed in the works prepared for it, and had begun its fire, the old walls of Astorga began to crumble. The light Spanish pieces on the enceinte were overpowered, despite of the gallant way in which the gunners stuck to their work[250]. By noon on the 21st of April the north-western angle of the walls of Astorga had been beaten down, and the fallen stones, there being no ditch, had accumulated at the foot of the broad breach, so as to give an easy entrance. Fortunately for the defence, there was a large church just inside the angle: its roof and tower had been shot down, but the garrison had made themselves strong in the lower parts of the building, and threw up traverses from it to the wall on each side of the breach. This gave them a second line of defence, though but a weak one, and when Junot sent in a summons in the afternoon Santocildes refused his offer. At seven the French general bade 700 men storm the breach; the forlorn hope was composed of the voltigeur and grenadier companies of the Irish Legion and the 47th of the Line. The column penetrated to the foot of the breach without much difficulty, though exposed to heavy musketry from the walls, and a flanking fire from the suburb of the Reteibia. The breach was carried, and, in addition, a house built with its back to the ramparts just inside the enceinte. But the assailants could get no further, owing to the murderous fire which the Spaniards kept up from behind the ruined church and the traverses. After an hour of desperate attempts to break in, they took shelter, some in the house that they had captured, but the majority behind the lip of the breach, where they covered themselves as best they could, by piles of débris built in with their haversacks, and even with the corpses of the fallen. Under this poor shelter they lay till dark, suffering heavily. During the night the troops in the trenches ran out a line of gabions from the front works to the foot of the walls, and by dawn had opened a good communication with the men at the breach, though they had to work under a furious but blind fire from above.
At dawn on April 22, Santocildes surrendered. He might have held out some hours longer behind his inner defences, if he had not exhausted nearly all his musket ammunition in resisting the storm. There were less than thirty cartridges a head left for the infantry of the garrison, and only 500 pounds of powder for the artillery. The defence had been admirable, and, it may be added, very scientific, a fact proved by the low figures of the dead and wounded, which did not amount to 200 men[251]. The French, in the assault alone, lost five officers and 107 men killed, and eight officers and 286 men wounded[252]. Junot was thought to have been precipitate in ordering the storm: his excuse was that there were less than two hours of daylight left, and that, if he had deferred the attack till next morning, the Spaniards would have retrenched the breach under cover of the dark, and made it impracticable. The siege cost the 8th Corps in all 160 killed and some 400 wounded, a heavy butcher’s bill for the capture of a mediaeval fortress armed with only fourteen light guns. Two thousand five hundred prisoners were taken, as shown by Santocildes’ lists, but Junot claimed to have ‘captured 3,500 fine troops, all with good English muskets, and well clothed in English great coats,’ as well as 500 sick and wounded—impossible figures.
On the morning of the surrender Mahy made a feeble demonstration against the covering troops, on both the passes of Manzanal and Foncebadon, while Echevarria beat up the force at Penilla which lay facing him. All three attacks were checked with ease, the Galician army not being able to put more than 6,000 men in the field on the three fronts taken together. Its loss was heavy, especially at Penilla.
After detaching the 22nd Regiment, which was ordered to endeavour to communicate with Bonnet in the Asturias, and garrisoning Astorga with two battalions, Junot drew back the greater part of his corps to Valladolid and Toro. He had been ordered to place himself near Ney, in order to aid and cover the 6th Corps in the oncoming siege of Ciudad Rodrigo. At the same time he received the unwelcome news that Masséna had been named Commander-in-Chief of the Army of Portugal, and that the 8th Corps was placed under his orders.
