A history of the Peninsular War, Vol. 2, Jan.-Sep. 1809

St. Cyr moved forward on November 5, with the four divisions of Souham, Pino, Reille, and Chabot, which (as we have seen) amounted in all to about 23,000 men. He had resolved to use Pino and Reille—some 12,000 men—for the actual siege, and Souham and Chabot for the covering work. Accordingly the weak division of the last-named officer was left to watch the ground at the foot of the passes, in the direction of Figueras and La Junquera, while Souham took up the line of the river Fluvia, which lay across the path of any relieving force that might come from the direction of Gerona. St. Cyr remained with the covering army, and gave the conduct of the siege to Reille, perhaps because he had already made one attack on the town in August.

On November 6 Reille marched down to the sea, driving before him the Spanish outlying pickets, and the peasantry of the suburban villages, who took refuge with their cattle in Rosas. On the seventh the investment began, Reille’s own division taking its position on the marshy ground opposite the town, while Pino encamped more to the left, upon the heights that face the fort of the Trinity. The head quarters were established at the village of Palau. A battalion of the 2nd Italian light infantry was placed far back, to the north-east, to keep off the somatenes of the coast villages about Llanza and Selva de Mar from interfering in the siege.

Next day the civil population of Rosas embarked on fishing-vessels and small merchantmen, and departed to the south, abandoning the whole town to the garrison. They just missed seeing some sharp fighting. The covering party who had been detached to the neighbourhood of Llanza were beset during a dense mist by the somatenes of the coast: two companies were cut to pieces or captured; the rest were saved by General Fontane, who led out three battalions from Pino’s lines to their assistance. While this engagement was in progress, the garrison sallied out with 2,000 men to beat up the main camp of the Italians; they were repulsed after a sharp fight; the majority got back to the citadel, but one party being surrounded, Captain West of the Excellent landed with 250 of his seamen and marines, cut his way to them, and brought them off in safety. West had his horse shot under him (a curious note to have to make concerning a naval officer), and lost ten men wounded.

After the eighth there followed seven days of continuous rain, which turned the camp of Reille’s division into a marsh, and effectually prevented the construction of siege works in the low-lying ground opposite to the town. The only active operation that could be undertaken was an attempt to storm the fort of the Trinity, which the French believed to be in far worse condition than was actually the case. It was held by eighty Spaniards, under the Irish Lieutenant-Colonel Fitzgerald, and twenty-five of the Excellent’s marines[57]. The six voltigeur and grenadier companies of the 2nd Italian light infantry delivered the assault with great dash and resolution. But as the strong frontal tower of the fort was high and unbreached, they could make no impression, their ladders proved useless, and they were repulsed with a loss of sixty men. Their leader, the chef-de-bataillon Lange, and several other officers were left dead at the foot of the walls.

Seeing that nothing was to be won by mere escalade, Reille had to wait for his siege artillery, which began to arrive from Perpignan on November 16. He at once started two batteries on the Puig-Rom to breach the Fort of the Trinity, and when the ground had begun to grow dry in front of the town, opened trenches opposite its north-eastern angle. When a good emplacement had been found a battery was established which played upon the citadel, and commanded so much of the harbour that Reille hoped that the British ships would be compelled to shift their anchorage further out to sea. The Spaniards and the Excellent replied with such a heavy fire that in a few hours the battery was silenced, after its powder magazine had been exploded by a lucky shell [November 19].

Next day, however, the French repaired the damage and mounted more guns, whose fire proved so damaging that Captain West had to move further from the shore. The assailants had established a marked superiority over the fire of the besieged, and availed themselves of it by pushing out parallels nearer to the town, and building four more breaching batteries. With these additional resources they began to work serious damage in the unstable bastions of the citadel. They also knocked a hole in the Fort of the Trinity: but the breach was so far from the foot of the wall that it was still almost inaccessible, the heaps of rubbish which fell into the ditch did not even reach the lowest part of the gap.

On the twenty-first the Excellent was relieved by the Fame, and Captain West handed over the task of co-operating with the Spaniards to Captain Bennett. The latter thought so ill of the state of affairs, that after two days he withdrew his marines from the Trinity Fort, an action most discouraging to the Spaniards. But at this juncture there arrived in the bay the Impérieuse frigate, with her indefatigable commandant Lord Cochrane, a host in himself for such a desperate enterprise as the defence of the much-battered town. He got leave from his superior officer to continue the defence, and manned the Trinity again with his own seamen and marines. They had hardly established themselves there, when the Italian brigade of Mazzuchelli made a second attempt to storm the fort: but it was repulsed without even having reached the foot of the breach.

Cochrane, seeing that the battery which was playing on the Trinity was on the very edge of a precipitous cliff, resolved to try whether it would not be possible to surprise it at night, by landing troops on the beach at the back of the Puig-Rom; if they could get possession of the guns for a few minutes he hoped to cast them over the declivity on to the rocks below. O‘Daly lent him 700 miqueletes from the garrison of the town, and this force was put ashore with thirty of the Impérieuse’s marines who were to lead the assault. The Italians, however, were not caught sleeping, the attack failed, and the assailants were beaten back to the rocks by the beach, with the loss of ten killed and twenty wounded, beside prisoners[58]. The boats of the frigate only brought off 300 men, but many more escaped along the beach into the hilly country to the east, and were neither captured nor slain [November 23]. The sortie, however, had been disastrous, and the Governor, O’Daly, was so down-hearted at the loss of men and at the way in which the walls of the citadel were crumbling before his eyes, that he began to think of surrender. Nor was he much to blame, for the state of things was so bad that it was evident that unless some new factor was introduced into the siege, the end was not far off. The utter improbability of relief from without was demonstrated on the twenty-fourth. Julian Alvarez, the Governor of Gerona and commander of the Spanish forces in the Ampurdam, was perfectly well aware that it was his duty to do what he could for the succour of Rosas. But his forces were insignificant: Vives had only given him 2,000 regular troops to watch the whole line of the Eastern Pyrenees, and of this small force half was shut up in Rosas. Nevertheless Alvarez sallied out from Gerona with two weak battalions of Ultonia and Borbon, and half of the light infantry regiment of Barcelona. Picking up 3,000 local miqueletes he advanced to the line of the Fluvia, where Souham was lying, with the division that St. Cyr had told off to cover the siege. The Spaniards drove in the French outposts at several points, but immediately found themselves opposed by very superior numbers, and brought to a complete stand. Realizing that he was far too weak to do anything, Alvarez retreated to Gerona after a sharp skirmish. If he had pushed on he would infallibly have been destroyed. O’Daly received prompt news of his colleague’s discomfiture, and saw that relief was impossible. The fact was that Vives ought to have brought up from Barcelona his whole field army of 20,000 men. With such a host Souham could have been driven back, and Reille compelled to relax the investment, perhaps even to raise the siege. But the Captain-General preferred to waste his men and his time in the futile blockade of Duhesme, who could have been just as well ‘contained’ by 10,000 somatenes as by the main Spanish army of Catalonia. The only attempt which Vives made to strengthen his force in the Ampurdam was to order up to Gerona the Aragonese division of 4,000 men under the Marquis of Lazan, which was lying at Lerida. This force arrived too late for the skirmish on the Fluvia, and when it did appear was far too small to accomplish anything. Alvarez and Lazan united had only 8,000 bayonets, while St. Cyr’s whole army (as we have already seen) was 25,000 strong, and quite able to maintain the siege, and at the same time to provide a covering force against a relieving army so weak as that which now lay at Gerona.

The siege operations meanwhile were pushed on. Fresh batteries were established to sweep the harbour, and to render more difficult the communication of the citadel and the Trinity fort with the English ships. A new attack was started against the eastern front of the town, and measures were taken to concentrate a heavier fire on the dilapidated bastion of the citadel, which had been destroyed in the old siege of 1794 and never properly repaired. On the twenty-sixth an assault was directed by Pino’s division against the town front. This was defended by no more than a ditch and earthwork: the Italians carried it at the first rush, but found more difficulty in evicting the garrison from the ruined houses along the shore. Five hundred miqueletes, who were barricaded among them, made a very obstinate resistance, and were only driven out after sharp fighting. One hundred and sixty were taken prisoners, less than a hundred escaped into the citadel: the rest perished. The besiegers at once established a lodgement in the town, covering themselves with the masonry of the demolished houses. It was in vain that the Fame and Impérieuse ran close in shore and tried to batter the Italians out of the ruins. They inflicted considerable loss, but failed to prevent the enemy from finding shelter. Next night the lodgement in the town was connected with the rest of the siege works, and used as the base for an attack against a hitherto unmolested front of the citadel.

Just after the storming of the town, the garrison received the only succour which was sent to it during the whole siege; a weak battalion of regulars from the regiment of Borbon was put ashore near the citadel under cover of the darkness. It would have been more useful on the preceding day, for the defence of the outer works. After the arrival of this small succour the Governor, O’Daly, sent eighty men of the Irish regiment of Ultonia to reinforce Cochrane in the Trinity fort, withdrawing a similar number of miqueletes to the citadel.
