Thirteen thousand men seemed enough to make an end of an old-fashioned fortress like Gerona, held by a garrison which down to the first day of the siege counted no more than 400 regular troops—that same Irish regiment of Ultonia which had stood out against Duhesme’s first attack in June. It was fortunate for the defenders that at the very moment of the arrival of the French they received a powerful reinforcement. The light infantry regiment named the 2nd Volunteers of Barcelona, 1,300 strong, entered the city on the night of July 22[313], slipping between the heads of Duhesme’s and Reille’s columns. This corps had formed part of the garrison of Minorca: instead of being landed at Tarragona with the rest of Del Palacio’s troops, it was dropped at San Feliu, the nearest port on the coast to Gerona, and had just time to reach that place before its investment was completed.
Duhesme had resolved to avoid for the future the fruitless attempts at escalade, which had cost him so many men during his first siege of Gerona, and to proceed by the regular rules of poliorcetics. He had with him a battering-train more than sufficient to wreck the ancient walls of the city: accordingly he opened a secondary attack on the lower town on the left of the Oña, but turned the greater part of his attention to the citadel of Monjuich. If this work, which from its lofty hill commands the whole city, were once mastered, the place could not hold out for a day longer. By this arrangement the charge of the main attack fell to Reille, and Duhesme himself undertook only the demonstration against the Mercadal. The French began by establishing themselves on the lower slopes of the tableland of which Monjuich occupies the culminating point. They found shelter in three ruined towers which the garrison was too weak to occupy, and raised near them three batteries with six heavy guns and two howitzers, which battered the citadel, and also played upon certain parts of the town wall near the gate of San Pedro. The batteries in Duhesme’s section of the siege-lines consisted only of mortars and howitzers, which shelled and several times set fire to the Mercadal, but could make no attempt to open breaches in its walls.
The siege-approaches of the French before Gerona were conducted with an astonishing slowness: it was not till sixteen days after they had established themselves on the slopes round Monjuich, that they began to batter it in a serious fashion [Aug. 12]. This delay was partly due to the steepness of the ground up which the guns had to be dragged, partly to the necessity for sending to Figueras for extra artillery material, which could only be brought slowly and under heavy escort to the banks of the Ter. But Duhesme’s slackness, and the want of skill displayed by his engineer officers, were responsible for the greater portion of the delay. Moreover the investment of Gerona was so badly managed, that not only did the garrison keep up a regular communication at night with the chiefs of the somatenes who lay out on the hills to the west, but convoys repeatedly left and entered the town in the dark, without meeting a single French picket or patrol.
This delay of a fortnight in pressing the attack on Gerona led to two important results. The first was that the news of the capitulation of Baylen reached both camps, producing grave discouragement in the one, and a disposition for bold action in the other. The second was that Del Palacio and the troops from Minorca had time granted to them to prepare for interference in the siege. The marquis had landed at Tarragona on July 23, with all his division, save the regiment sent to St. Feliu and the Aragonese battalion which had been directed on Tortosa. Immediately on his arrival the insurrectionary Junta of Catalonia transferred itself from Lerida to Tarragona and elected Del Palacio Captain-General of the principality. Thus a real central authority was established in the province, and a single military direction could at last be given to its armies. The new Captain-General was well-intentioned and full of patriotism, but no great strategist[314]. His plan was to press Barcelona with the bulk of his regular forces, so that Lecchi might be compelled to call for instant help from Duhesme, while a small column under the Conde de Caldagues was to march on Gerona, not so much with the hope of raising the siege, as to aid the somatenes of the Ampurdam in harassing the investing force and throwing succours into the city[315].
Accordingly the main body of Del Palacio’s army, the regiments of Soria, Granada, and Borbon, with Wimpfen’s two Swiss battalions from Tarragona, marched on the Llobregat, drove in Lecchi’s outposts, and confined him to the immediate environs of Barcelona. The somatenes came to give help in thousands, and a cordon of investment was established at a very short distance from the great city. On the seaside Lord Cochrane, with the Impérieuse and Cambrian frigates, kept up a strict blockade, so that Lecchi, with his insufficient and not too trustworthy garrison of 3,500 Swiss and Italian troops, was in a most uncomfortable position. If it had not been that Barcelona was completely commanded by the impregnable citadel of Monjuich, he could not have maintained his hold on the large and turbulent city. His last outpost was destroyed on July 31: this was the strong castle of Mongat, six miles out on the coast-road from Barcelona to Mataro. It was held by a company of Neapolitans, 150 men with seven guns. Attacked on the land-side by 800 miqueletes under Francisco Barcelo, and from the sea by the broadside of the Impérieuse, the Italian officer in command surrendered to Lord Cochrane, in order to save his men from massacre by the Catalans. Cochrane then blew up the castle, and destroyed the narrow coast-road on each side of it by cuttings and explosions[316], so that there was no longer any practicable route for guns, horses, or wagons along the shore. Thus hemmed in, Lecchi began to send to Duhesme, by various secret channels, appeals for instant aid, and reports painting his situation in gloomy but not much exaggerated colours. He asserted that the somatenes were pushing their incursions to within 600 yards of his advanced posts, and that there were now 30,000 Catalans in arms around him. If he had said 10,000 he would have been within the limits of fact.
On August 6 the Captain-General, after carefully arranging his troops in the positions round Barcelona, sent off Caldagues to harass Duhesme in the north. This enterprising brigadier-general was given no more than four companies of regulars, three guns, and 2,000 miqueletes from the Lerida district under their colonel, Juan Baget. Marching by the mountain road that goes by Hostalrich, and picking up many recruits on the way, he established himself on the fourteenth at Castella, in the hills that lie between Gerona and the sea. Here he was met by all the somatenes of Northern Catalonia, under their daring leaders, Milans and Claros.
The investment of Gerona was so badly managed, that when the news of Caldagues’ approach was received, two colonels (O’Donovan of the Ultonia Regiment and La Valeta of the Barcelona Volunteers) were able to penetrate the French lines and to confer with the commander of the army of succour. These two officers were really conducting the defence, for the titular governor, Bolivar, seems to have been a nonentity[317], who exercised no influence on the course of events. At a council of war which they attended, it was resolved to try a stroke which was far bolder than anything that the Captain-General had contemplated when he sent Caldagues northward. The relieving force was to attack from the rear Reille’s troops on the heights before Monjuich, while at the same time every man that could be spared from the garrison was to be flung on the breaching batteries from the front. Duhesme’s army in the plain beyond the Oña was to be left alone: it was hoped that the whole business would be over before he could arrive at the spot where the fate of battle was to be decided. There were somewhat over 8,000 men disposable for the attack: 1,000 regulars and four hundred miqueletes were to sally out of Gerona: Caldagues could bring up 7,000 more, all raw levies except the four companies of old troops that he had brought from Tarragona. He had also five field-guns. As Duhesme and Reille had 13,000 men, of whom 1,200 were cavalry, it was a daring experiment to attack them, even though their forces were distributed along an extensive line of investment.
A bold and confident general, placed in Duhesme’s position, would not have waited to be attacked in his trenches. The moment that he heard of the approach of Caldagues, he would have drawn off half his battalions from the siege, and have gone out to meet the relieving army, before it could get within striking distance of Gerona. But Duhesme was not in the mood for adventurous strokes: he was chilled in his ardour by the news of the disaster of Baylen: he was worried by Lecchi’s gloomy reports; and he had been pondering for some days whether it would not be well to raise the siege and march off to save Barcelona. But the ravages which his bombardment was producing in the beleaguered city, and the fact that a breach was beginning to be visible in the walls of Monjuich, induced him to remain before the place, hoping that it might fall within the next few days. If this was his determination, he should at least have made preparations to receive Caldagues: but no attempt whatever appears to have been made to resist an attack from without.
On the morning of August 16, the Spaniards struck their blow. Between nine and ten o’clock in the morning, the 1,400 men of the garrison deployed from behind the cover of the citadel, and charged down upon the trenches and batteries of the besiegers[318]. They completely swept away the battalion of the 5th Legion of Reserve, which was furnishing the guard of the trenches, captured the siege-guns, and set fire to the fascines of the batteries. Then pushing on, they drove off the Swiss battalion of the Valais, and the two Tuscan battalions of the 113th Regiment, pressing them down hill towards Reille’s head quarters at Puente Mayor. The French general rallied them upon the 1st Régiment de Marche, which formed his reserve at this point of the line, and mounting the slope retook some of the works which had been lost. But at this moment Caldagues’ whole army appeared upon the heights, pressing forward in four columns with great confidence. The sight of these multitudes checked Reille, who hastily drew back, evacuated Puente Mayor and withdrew to the other bank of the Ter. Duhesme, on his side, abandoned all his outlying positions and concentrated his whole force in front of the village of Santa Eugenia.
The Catalans were wise enough not to descend into the plain, where Duhesme’s cavalry and guns would have had a free hand. Caldagues refrained from passing the Ter, and merely drew up his army on the slopes above Puente Mayor, ready to receive battle. But the expected attack never came; Duhesme held back all the afternoon, and then fled away under cover of the darkness. His losses in the fighting on the hills had not been heavy—seventy-five killed and 196 wounded—but his spirit was broken. He would not risk an assault on such a strong position with his motley and somewhat demoralized army. For a moment he thought of leading his whole force back to Reille’s base at Figueras: but the reflection that in this case Lecchi would probably be destroyed, and he himself be made responsible for the loss of Barcelona by the Emperor, deterred him from such a cowardly move. Bidding Reille take the northern road and keep open the communications with France, he drew off the rest of his army to the south to rejoin his Italian comrades. The move was made with some panic and precipitation: the remaining siege-guns were buried in a perfunctory fashion, and some stores destroyed. Then Duhesme marched away over the mountains, pursued by the somatenes of Milans; while Reille retired across the plains of the Ampurdam, and had a fairly easy journey to Figueras. Claros, who tried to harass his retreat, never dared to close in upon him in the open country, fearing his cavalry and guns. Far more toilsome was the lot of Duhesme’s column, which had to march for twenty miles through very broken ground, chased by the levies of Milans, to whom the whole district was familiar. When he reached the sea at Malgrat he found that his troubles were only growing worse. The somatenes hung on his right flank, while Lord Cochrane’s frigate the Impérieuse followed him on the left hand, giving him a broadside whenever his march lay within cannon-shot of the beach. Moreover, the peasants had been cutting and blasting away the road under Cochrane’s direction; and at each point where one of these obstructions had been made, it was necessary to drag the guns and wagons of the column across almost impassable hillsides[319]. Finding that he was making no appreciable progress, and that his men were growing utterly demoralized, Duhesme at last took a desperate step. He blew up his ammunition, burnt his baggage, cast his field-guns into the sea, and fled away by hill-tracks parallel with the shore. After long skirmishing with the somatenes he reached Mongat, where Lecchi came out to his aid with 1000 men and a battery—all that could be spared from the depleted garrison of Barcelona. There the Catalans stayed their pursuit, and Duhesme’s harassed battalions poured back into the city, sick of mountain warfare, half-starved, and carrying with them nothing but what they brought in on their backs [August 20]. As a fighting force for offensive operations they were useless for some weeks, and all that their general could do was to hold for foraging purposes as much of the open ground about Barcelona as he could manage to retain. Nothing more could be essayed till Napoleon should vouchsafe to send heavy reinforcements to Catalonia, for the purpose of reopening the severed communications with France.
