The Siege of Ajaccio

While the revolution was rekindled in the north, the British pursued their own ends in Corsica. Rear Admiral
Thomas Mathews had been informed in February that a Spanish warship, the 64-gun
San Isidro,
[1] was at Ajaccio harbor. Under the command of the French captain
Gilles René de Lage de Cueilly, the
San Isidro had participated in the landing of Spanish troops in Italy early in the war, but had been separated from its squadron and damaged in a storm, requiring de Lage to take refuge at the Corsican port. Once there, however, his activities were not purely convalescent. The Spanish fleet had urgent need of skilled sailors, and the Genoese authorities complained that de Lage not only recruited from among their citizens but made the
San Isidro into a “floating hotel” for deserters. Mathews, on the basis of the
San Isidro’s past service and its present occupation, determined to neutralize the ship. Mathews had already demonstrated his cavalier attitude towards the rights of neutrals and chose as his instrument Commodore
William Martin, who just a few months previously had trained his guns upon Genoa and threatened to burn the city if the Republic did not cease its material collaboration with Spain. Clearly the admiral’s intent was not to negotiate.
At the end of February, Martin’s detachment led by his flagship
Ipswitch reached Isola Rossa, where they were to rendezvous with Captain
William Berkeley’s 70-gun
Revenge before proceeding to Ajaccio. Theodore, aboard the
Revenge, was made aware of the British plans and did his best to support them, eager not only to make as much as he could of the fleet’s presence but to prove his usefulness to his British benefactors. He had already dispatched messengers to Marquis
Luca d’Ornano and Count
Antonio Colonna-Bozzi which instructed him them to bring their forces to Ajaccio to rendezvous with the British fleet and begin a siege of the town. It was an optimistic plan - d’Ornano had failed to turn up at Porto Vecchio when Theodore had arrived there, and thus far had made no indication, despite his earlier claimed title of “Regent of the Kingdom of Corsica,” that he maintained any allegiance to Theodore. Colonna’s loyalty was less in doubt, but without d’Ornano’s support the “Free Battalion” had no chance of threatening Ajaccio on its own. Nevertheless, given his chilly reception in the north the king no doubt saw this as his last chance to spark a royal restoration and prove that the popular loyalty he had boasted of in London was not merely a sham. Even as events in the north moved inexorably towards the clash at Morosaglia, Theodore was sailing away, bound for the
Dila.
The flotilla arrived late on March 2nd. De Lage had anchored his ship in the northwestern portion of the bay around 70 meters from the shore, where the British would be compelled to sail under the guns of Ajaccio’s citadel. Despite his questionable "recruiting" of men from the Genoese forces, de Lage expected that Commissioner
Stephano Veneroso would side with him, as much to defend the sovereign rights of the Republic as to support his Spanish guests. As the fleet took up a position to prevent any possible escape by de Lage, Theodore - who had transferred with his men and supplies to the 50-gun
Salisbury under the command of Captain
Peter Osborne - landed at the Campo dell’Oro with some 150 men, an assortment of exiles, foreign recruits, and recently-embarked volunteers from the Balagna. D’Ornano soon made an appearance, but with a smaller force than Theodore had hoped; he had scarcely more men than the king, and had not brought his artillery. The marquis greeted his monarch graciously, but clearly he intended to act foremost as an observer and gauge the situation before committing himself as a combatant. Colonna was nowhere to be seen.
Martin’s orders did not even mention Theodore. Although the king no doubt hoped to use the British fleet to capture the city for his cause, the commodore’s only goal was the capture or destruction of the
San Isidro. Ajaccio itself was of interest to Martin only insofar as its guns threatened his operations in the bay. De Lage had requested the support of Commissioner Veneroso's batteries, as well as permission to land some of his own ship’s guns in ersatz coastal batteries so as to offer a stiffer defense. But Veneroso had also received a note from Martin, who informed him in no uncertain terms that if the Genoese did not observe their “neutrality” - which Martin defined as taking no action whatsoever to aid the Spanish - he would direct his fleet to bombard the city “without mercy.” Faced with this dilemma, Veneroso’s solution was to do nothing at all. He simply pretended he had not received
any letters, and provided neither commander with a response. The Genoese batteries would remain silent observers of the battle to come. In so doing the commissioner sealed the fate of the
San Isidro, which would have to face Martin's full might on its own.
At around four in the morning on the 3rd, Martin led the
Ipswitch into the harbor along with the
Revenge and the 44-gun frigate
Mary Galley. De Lage appears to have shot first, whereupon the three British ships warped into position to present their broadsides to the Spanish warship and opened fire. As the fight was beginning, British longboats were dispatched to land marines and armed sailors on the coasts on either side of the
San Isidro, possibly as a means to encircle and capture the vessel as the ship was well within musket-shot of the shore. Theodore remained aboard the
Salisbury, which unengaged, some distance away off the shore of Campo dell’Oro; in theory, the rebels were to assist the British in the capture of the Spanish ship, but Martin seems to have given no serious thought to coordinating with d’Ornano or Theodore. As the ships exchanged volleys, d’Ornano’s men crested the hill of Aspretto overlooking the bay from the east, but thereafter remained observers and did not participate in the battle.

The ship "E," being towed into position by longboats, is an unnamed British warship. "G" is a British longboat, either serving as an observation post or disembarking troops. The ship "F" is galliot, possibly British or Genoese. The San Isidro's three longboats, already deployed for evacuation, can be seen above the ship.
The
San Isidro could not long withstand the punishment of the combined British broadsides. By mid-morning the ship resembled a splintered hulk, while the Spaniards had succeeded only in causing light damage to the
Revenge. Martin later reported that his squadron’s fire had set the Spanish ship ablaze, but in fact the Spaniards had done it themselves; having fought as hard has he was able, de Lage chose to burn his battered ship rather than allow it to fall into the hands of the British. Unfortunately, the crew performed their duties a little too effectively. The fires raced to the magazine more quickly than anticipated, and around noon the
San Isidro abruptly exploded in a massive fireball with some of the crew still on board. De Lage had already evacuated, as had most of his crew, but the Spaniards lost at least 50 men in the detonation.
[2][A]
The survivors of the
San Isidro, many of them wounded, escaped the wreck in three of the ship’s boats which de Lage - knowing quite well that he was fighting a doomed fight - had put overboard on the landward side and prepared beforehand. Despite having already landed men on the beach, however, Martin chose not to attack the Spanish. His objective was to neutralize the Spanish vessel, which had been accomplished by its destruction. There was no advantage to the Royal Navy in violating Genoese sovereignty further to accost a stranded and bloodied Spanish crew. Martin withdrew the landing parties and ordered the fleet to prepare for departure, much to the relief of the citizens of Ajaccio, who had feared bombardment after a few stray shots raked the town and had gathered around the city’s cathedral to pray for deliverance. Some of the citizens came forth from the town afterwards to aid the Spanish wounded, which d’Ornano did not interfere with.
Theodore faced a difficult and crucial decision. Martin was leaving without delay; he had no objection to taking Theodore with him, but he would not be returning to Corsica anytime soon. Berkeley, in the commodore’s view, had spent quite enough time intriguing with rebels, and his vessel could no longer be spared given the difficult time the fleet was already having with enforcing their Italian blockade. Safety lay over the water, but also defeat and ignominy; having arrived to stir up a new rebellion in his favor, if he were to sail away now his throne might be forever lost. Yet Colonna had not yet arrived, and d’Ornano remained dubious; he had made an appearance, but seemed so far content only to watch, and Theodore feared the marquis might decide to hand him over to the Genoese.
D’Ornano had been clearly gravitating towards the Genoese camp over the past year and had little sympathy with the rebellion in the north, perhaps in part because of his personal dislike for Count
Gianpietro Gaffori. Like many other former rebel leaders in the
Dila, he valued his autonomy above all, and a friendly
détente with the feeble Genoese regime appeared more attractive than the possibility of playing second fiddle to a “national” government run by Gaffori and his friends out of Corti or the Castagniccia. Clearly, however, the situation was complex and changing rapidly, and under such circumstances d’Ornano was not about to limit his options by flatly refusing the King of Corsica. It was undoubtedly for this reason that he appeared before Ajaccio as ordered. In so doing, he could comply with the letter of Theodore’s instructions and observe events firsthand. Even if Theodore’s “return” came to nothing, perhaps a demonstration in front of the walls of Ajaccio would push the Genoese towards offering him a better deal for his friendship.
The king hesitated - and then, finally, took the plunge. Theodore disembarked from the
Salisbury along with his company of followers and the last of his supplies from Livorno, including provisions, muskets, and gunpowder. It has been suggested that the British supplied him with additional powder; in any case, his supplies - modest as they were - would prove to be of tremendous import in the fight ahead. After an uneasy two days of waiting, Colonna finally made his appearance, along with the better part of his battalion and
Matthias von Drost, Theodore’s cousin. The siege could now begin in earnest.
Ajaccio was, by all appearances, a strong defensive position. The citadel, located on a promontory jutting into the bay, was no late medieval tower; it was a proper bastion fort of the gunpowder age, with gun emplacements in all directions. The town center lay directly below the citadel and had its own exterior wall, albeit not as formidable a defense as the citadel's bastions. Outside these walls and extending along the coast to the north was the
Borgu, a suburb largely populated by native Corsicans (as opposed to the city’s mainly Genoese residents).
Veneroso’s garrison forces were also formidable. They included around 475 regulars, mainly Italians under the command of Colonel
Gio Tommaso Varenne (“John Thomas Warren,” an Irishman) and one detached company of Colonel
Rodolfo Antonio Jost’s Grison infantry. They were supported by the Greek militia companies, then numbering 185 men in total, and around 120 provincial militia (“
truppa paesana”), for a total of approximately 780 infantrymen under arms. The Spanish sailors and marines who had escaped the destruction of the
San Isidro were also present, although many of these survivors were wounded and it was unclear whether they would fight for Genoa against the Corsican rebels, a war they had no part in. There were certainly common citizens willing to fight if it came to that extremity, but it was unclear how well they would be able to. Veneroso had discovered upon taking his post that many of the “reserve” muskets in the citadel’s armory were nonfunctional antiques, and the Genoese state had not possessed the wherewithal to resupply him since then. In addition to its infantry, the garrison had 25 dedicated
bombardieri (artillerymen) to direct the batteries of the citadel. Its batteries were armed with a total of 35 serviceable guns, which in typical Genoese fashion were of myriad calibers: Two enormous bronze 54-pounders, two 34-pounders, three 25-pounder demi-cannons, a single 18-pounder culverin, four 14-pounder bronze demi-culverins, six 9-pounder iron sakers, six 8-pounder bronze sakers, five 4-pounder falcons, three 2-pounder falconets, and two bronze pierriers (“
petrieri”), wide-mouthed mortars which lobbed 40-pound stone balls.
Against this force the Corsicans had, at the time of Colonna’s arrival, just over 500 soldiers - approximately 300 of Colonna’s men (mostly free battalion “regulars” with some militia), fewer than 200 of d’Ornano’s militia, and Theodore’s 150 or so assorted followers and hirelings, not all of whom were soldiers. They had no artillery whatsoever; d’Ornano had a half-dozen or so iron guns obtained from Theodore years prior but had not brought them to Ajaccio, which would take some time. Clearly a direct assault was impossible. The rebels could simply cut off the city and wait, but as long as Ajaccio could be supplied by sea this was unlikely to amount to much, as d’Ornano himself had found in his long and fruitless attempts to besiege the city in years past.
Plan of the Gulf and Bay of Ajaccio ("Hiace"). Note that North on this map is towards the left.
Theodore, however, had a plan. Ajaccio’s harbor, and the site of the recent battle, was located in a small cove - the Bay of Ajaccio - which protruded northwards from the larger Gulf of Ajaccio. The mouth of the bay was marked on the west side by Ajaccio itself, and on the east by the hill of Aspretto, which had briefly been occupied by d’Ornano’s men during the naval battle. The two positions were scarcely a mile apart from one another, yet while the western point was held by Ajaccio's formidable citadel, Aspretto was unfortified. Surveying the bay from the deck of the
Salisbury, Theodore had perceived that the point of Aspretto was of paramount strategic importance. A battery of guns positioned there could effectively dominate the entrance to the harbor, cutting off the city’s supply route. Combined with a land blockade, this would place Ajaccio in a vise that would eventually compel its surrender.
[3][B]
To make this plan a reality, however, the rebels would need artillery. D’Ornano, as mentioned, had a handful of guns in storage, but they would take some time to bring to the bay, and he had very little powder or ammunition. Theodore had some powder suitable for artillery, but he did not have cannonballs. There was, however, another potential source of artillery and shot much closer at hand, if a bit more challenging to procure. The
San Isidro was a 64-gun ship, which meant that 64 guns - or however many of those had survived the explosion intact - and a considerable number of cannonballs were resting just off the shore in less than 15 meters of water. Moreover, to put his ship in a safe position de Lage had anchored as far north in the bay as he could, which placed the wreck beyond the effective range of the citadel at the bay’s mouth, and thus the main Genoese battery. A salvage effort, if it could be protected from attack by the garrison, could provide the rebels with the guns and ammunition (though not the powder) they needed to realize Theodore’s plan, and it would not take a large battery to make Ajaccio’s harbor too hazardous to use.
D’Ornano was still a less than enthusiastic participant in this venture, but he was slowly coming around. News of the rebel victory at Morosaglia was helpful in this regard; the marquis no longer feared that Genoese ire would fall on him alone. The presence of Colonna's superior force may have also convinced him that Theodore had more going for him than mere hope. After stalling for some days, complaining of the logistical challenges he faced, d’Ornano finally got around to dispatching a party to start moving his artillery up to the bay.
In the meantime, there was much work to be done at Ajaccio. The royalists began digging a redoubt on Aspretto hill which Theodore dubbed "Fort Costa" in memory of his departed chancellor, while a company of Free Battalion soldiers occupied the church of Our Lady of Loreto less than a mile north of the city, which overlooked the wreck site. The actual salvage attempt itself got off to a slow start owing to inexperience, but the Corsicans were not altogether without relevant expertise. Ajaccio was the capital of the Corsican coral fishing trade, and thus home to many coral divers who worked routinely in much deeper waters than the Spanish guns were now in. As these fishermen were Corsican natives rather than Genoese, most lived in the
Borgo outside the city walls or in surrounding villages where the Genoese could not prevent them from fraternizing with (and working for) the rebels. With the help of these local divers and using log rafts to provide buoyancy, the rebels began dredging up cannonballs from the shallows, and on the 11th of March the Corsicans retrieved their first gun, an iron 12-pounder.
By the time Veneroso realized what the Corsicans were up to, they were well-entrenched north of the city. Veneroso still outnumbered them, but with a characteristic lack of initiative he hesitated to leave the security of his walls. An attempt was made on the morning of the 13th to chase the Corsicans off the beach with a company of Genoese troops in small boats, but the rebels fought off this attack with a fusillade of musketry and the Genoese were forced to retreat. A more successful attempt was made on the following day using an armed Genoese galliot, which trained its guns on the shore and drove off the salvage teams. The Corsicans fought back against this assault as well, but were outgunned by the cannon-armed galliot. The salvage mission was suspended, but on the 16th Fort Costa opened fire on the ship. Marquis d’Ornano had finally brought up a few of his guns. Although the range was long and he had precious little ammunition, a handful of shots were sufficient to scare off the galliot, for such a small ship could take precious little punishment from 24-pounder artillery.
Veneroso had now fully realized the danger that the rebels’ operations posed to the city and finally elected to mount a serious attack. On the 18th, Colonel Varenne marched out against the Church of Loreto with a mixed battalion of around 300 Genoese and Greek infantry. The Corsicans offered some resistance at the church, but there were only around 60 men holding the position and they soon retired before Varenne’s superior numbers. Yet this victory accomplished little; Varenne seized and destroyed a pair of guns which the Corsicans had dredged up and not yet moved from the beach, but Theodore’s men had by now amassed an eight-gun battery at Fort Costa, consisting of three of d’Ornano’s guns and five Spanish pieces from the wreck (although some of these guns were as yet without carriages). This proved sufficient to chase the ships in Ajaccio’s harbor from the bay entirely with just a few volleys.
Varenne considered an attack against Aspretto itself, but delayed the action until the following day. By then, the Corsicans were well-prepared for him, and Varenne was uneasy about his prospects. Rounding the bay posed a great danger to the Genoese, as while advancing against the redoubt they could easily be flanked or attacked from behind by Corsican militia coming from the north and east. The disposition of the Corsican defenses were unknown, as were the number of guns they possessed, some of which might be trained landward. Veneroso offered some supporting bombardment from the citadel, but the range was too long to be of much use, and the shots which reached the hill had minimal effect on the timber-clad earthworks of the battery. Varenne nevertheless made an attempt, coming as close as 600 yards to the rebel position on the hill. Observing the Corsicans manning the redoubt, however - as well as a pair of cannon trained on him - and still concerned about being flanked from the hills, Varenne decided to return to Ajaccio without offering battle.
Within a few days, Theodore received a curious letter from none other than Major
Micaglia Stefanopoli, one of the captains of the Greek militia. Stefanopoli had not turned traitor, but he clearly felt there was at least a chance the rebels might prevail, and feared that the Greek community would suffer harsh retribution or outright massacre in the event of a Corsican victory. It seemed prudent to reach out to the “King of Corsica” to gauge his reasonableness, and if possible to reach some understanding whereby the Greeks might survive whichever way the siege turned. In fact the major could not have wished for a better adversary; despite the general animosity towards the Greeks among the Corsican rebels, Theodore had no wish to harm them and in fact strongly desired to keep them on the island. It had been his policy since the beginning of his reign to encourage foreign settlement to increase the population and boost trade, and he was well aware of the aptitude of the Greeks for agriculture. The last thing he wanted was to see them destroyed.
Nevertheless, Theodore sought to use Stefanopoli’s anxiety to gain an advantage. In his reply, Theodore assured the major that he harbored no ill-will towards the Greek people, and that he fully intended to allow them to return to their farms in peace and prosper under the protection of law once the Genoese had been driven out. He lamented, however, the hostility of his Corsican followers, who considered the Greeks to be mere servants of the oppressive Genoese regime, and expressed his concern that he might not be able to control their thirst for “retribution” if the Greeks fought to the last to defend Ajaccio. Theodore agreed that “neutrality” on the part of the Greeks was quite impossible given their present circumstances, but he advised Stefanopoli that a token of support, demonstrating Greek friendship with the Corsican people, would go a long way towards demonstrating that they were not merely Genoese mercenaries. To put it plainly, Theodore played the extortionist: He was willing to use his influence to “protect” the Greeks, but only if paid, and he wanted his payment in gunpowder.
This plot did not immediately come to fruition. Stefanopoli was concerned, but not yet so concerned that he was ready to hand over munitions to the army besieging him. Theodore, however, could not wait around for the major to change his mind. Days earlier, he had received letters from both
Simone Fabiani and
Johann Friedrich von Neuhoff zu Rauschenburg pleading with him to return to the north. Despite the recent victory at Morosaglia, the royalist cause was not doing well; the various rebel groups had fallen out over the spoils of the victory and their commanders bickered ineffectually about what their next objectives should be. Although Theodore clearly wanted to see the siege through - and may not have fully trusted d’Ornano - he felt he could not delay his return any longer. Leaving the siege in the hands of d’Ornano (with Colonna and Drost as his lieutenants), Theodore took a guard of 80 men and took off northeast towards the Pass of Vizzavona.
Footnotes
[1] The exact armament of the San Isidro is not certainly known. The British reported the ship as a 70-gun vessel, but Spanish records give its original armament as 60 guns, and other documents suggest that it this had been altered to 64 by the 1740s. It may be that the ship was at least nominally armed with 64 guns by 1743 and the British simply estimated its complement at 70, which was the “normal” armament of a 3rd-rate ship of the line in the British system at that time. In its original 60-gun incarnation, the ship was equipped with twenty four 24-pounders, twenty six 12-pounders, and ten 6-pounders.
[2] Later that year, after returning to Spain, de Lage was subject to a court-martial over the loss of the
San Isidro. The court determined that no other outcome of the battle could have emerged given the overwhelming superiority of the British fleet, and absolved de Lage of blame for the ship’s loss.
[3] Traditionally the choice of Aspretto has been ascribed to a sudden epiphany by Theodore, giving further proof of his “military genius.” Although not one of the great generals of his day, Theodore was not without military aptitude; certainly his siege of Bastia in 1736 was well-executed. Still, Theodore was not an expert in artillery or naval matters, and it is a bit suspicious that this realization was made directly after spending time on a British ship among British officers (who
were experts in artillery and naval matters) observing the very site that Theodore subsequently identified. Indeed, had Veneroso decided to support de Lage and defend the
San Isidro with his guns, placing a battery on Aspretto hill would have been a logical second option to deal with the
San Isidro by forcing it out of the harbor. Theodore may merely have been the beneficiary of an observant British seaman.
Timeline Notes
[A] The destruction of the
San Isidro is largely historical. Indeed, Theodore was even there to see it IOTL. D'Ornano, however, didn't hold up his end of the bargain, and of course Colonna and his battalion didn't exist IOTL. Finding himself without support, Theodore sailed away in defeat with Martin's squadron.
[B] The strategic importance of Aspretto was observed by none other than Napoleon himself, who in 1793 wrote a “Plan for the Defense of the Gulf of Ajaccio” which underlined the importance of the point. “A battery placed on the Aspretto promontory,” he wrote, “would cross its fire with that of the fortress… it would have absolute control over the entrance and the interior of the harbor, where the enemy could anchor only after having put a stop to the said battery’s fire.” Later that year, as a colonel in command of the Republican artillery at the Siege of Toulon, Napoleon recognized the similarity of the two bays and the analogous placement of the “Hill of Cairo” which overlooked Toulon’s harbor. As with Aspretto and Ajaccio, a battery on this hill would render Toulon's defense untenable. The crucial hill was seized, the British and Royalists were forced to evacuate, and Napoleon was promoted to brigadier general and sent on to a new command with the Army of Italy. The fact that Napoleon was advocating the
construction of two batteries and a redoubt at Aspretto in 1793, as well as the fact I have yet to come across any indication of the Genoese manning a position there (despite having records for all sorts of other little manned towers along the coast), suggests to me that there were no serious fortifications there 50 years before Napoleon's writing.
