The Siege of Gaeta was the concluding event of the war between the Kingdom of Sardinia and the Kingdom of the Two Sicilies. It started on November 5, 1860 and ended February 13, 1861, and took place in Gaeta, in today's Southern Lazio (Italy).

[edit] Background

In the September of 1860, as the Garibaldine troops were moving towards his capital, Naples (see Mille expedition article), the king of Two Sicilies, Francis II, decided to leave the city on the advice of his Prime Minister Liborio Romano.

At the beginning, he planned to organise a resistance in Capua. However, after that city had also been lost to the Garibaldines in the aftermath of the battle of the Volturnus (October), he took refuge in the strong coastal fortress of Gaeta, together with his wife Marie Sophie.

Gaeta was one of the strongest military fortresses in Europe. It consisted of a triangle-shaped promontory (Mount Orlando) stretching out for more than one and a half kilometers, rising up to 169 m and with almost vertical cliffs on the seaward sides: this was connected to the mainland by a 600 m wide isthmus. The latter, called Montesecco ("Dry Mountain"), was the only way for a besieger to conquer the stronghold: the ships of the time were indeed considered too fragile to face the massive fortifications that encircled the promontory. The latter had been built since the time of emperor Charles V, and were provided with 220 guns, divided between 19 batteries. 230 more guns defended the fortress on the mainland side: a total of 450 cannons, 26 of which were short range mortars. However, they were mainly smoothbore arms, some dating back to the 18th century, and therefore rather imprecise. The massive castle, dating from the time of Emperor Frederick II but continuously updated, commanded the East side on the sea.

The Piedmontese forces were composed of the IV Army Corps, led by general Enrico Cialdini. His staff included the engineer general Luigi Federico Menabrea, future prime minister of Italy. Troops were composed of 808 officiers and 15,500 NCOs and soldiers, supported by 78 modern rifled guns, 65 mortars and 34 smoothbore guns. The most modern rifled ordnance could fire from a distance up to 5 kilometers, without risking any harm from the aged guns of the defenders. The Piedmontese fleet, under admiral Carlo di Persano, had 10 ships.

The Sicilian commander of the fortress of Gaeta was lieutenant general Francesco Millon. However, on November 10, he was replaced by Pietro Carlo Maria Vial de Maton, an 83 years old native of Nice who had served in the armies of Piedmont and Austria. The engineering arm was led by Count General Francesco Traversa, who reinforced the defences as much as possibile, often using makeshift solutions. Colonel Gabriele Ussani, an experienced soldier of the battles against Garibaldi, commanded the mainland front. The Sicilian forces amounted to 19,700 NCO and soldiers, 1,770 officers, 1,000 horses and mules: there were also 3,000 citizens of Gaeta. 17 ships of various nations (including Spain and France) kept open communications with the sea.

[edit] Beginning of the siege

Various dates are cited as the beginning of the siege; these range from November 5 to November 12. Cialdini installed his command position in Castellone, in what is today the city of Formia. 18 kilometers of roads, together with 15 bridges and causeways, were built for the transport of the artillery.

The situation for the soldiers and the inhabitants, massed in the very reduced space of the old city, soon proved unbearable. The Sicilian troops had neither blankets nor change of clothing. On November 18 the bombing was stopped to allow all the people not participating in the defence to leave the city.

The morale of the defenders, however, increased when veteran general Ferdinando Beneventano del Bosco, one of the few charismatic military figures of the Kingdom of Two Sicilies, arrived in Gaeta. He soon organized a sally for the dawn of November 29. 400 Chasseurs, supported by some foreign Carabiniers, managed to reach the summit of Montesecco, near the Roman mausoleum of Lucius Atratinus. However, they were repulsed by the Piedmontese reaction, and the action proved inconclusive. The last active operation of the Sicilians happened on December 4, also without any effect.

[edit] Sues for peace

On December 8 Francis II issued a proclamation to all his subjects, promising new liberties in lieu of the prosecution of the struggle against the invaders, and inciting them to guerrilla operations. The same day, Cialdini was ordered by the Piedmontese Prime Minister Cavour, to cease fire. Cavour, backed by the English government, had convinced Napoleon III to recall the French fleet from Gaeta and, in a letter sent on December 11, asked Francis II to leave Gaeta. However, the Neapolitan King did not accept the proposal. He in turn appealed to Napoleon not to recall his fleet, in order at least to save the military honour of the Kingdom and the Crown.

Hostilities began again on the night of December 13 and 14. In the meantime, epidemic typhus had begun to spread within the walls of Gaeta: Francis' field adjuntant was himself struck down and died on December 12.

More victims among the civil population were caused by the new Piedmontese batteries firing from Monte Tortano from December 15.

On December 27 a new capitulation proposal was sent to the Sicilian defenders or, as an alternative, a truce of 15 days. They were both rejected. The artillery duel restarted with increasing violence: 500 grenades a days were hurled against Gaeta, although most of them did not explode. The bombardment culminated on January 7, 1861, when the fortress received a shower of 8,000 shells, even if, again, with modest results.

[edit] End of the siege

The military operation was suspended for ten days on January 9, at the request of Napoleon III. When the armistice ended, foreign ships abandoned the harbour of Gaeta. The Piedmontese fleet, till then inactive in the port at Castellone, began a blockade, starting to bomb the fortress again on January 22. The Piedmontese launched 22,000 grenades, and the Sicilians replied with 11,000, damaging some of the opponents' batteries.

However, the defenders' situation appeared hopeless at that point, despite the efforts of the two sovereigns to raise the moral of the soldiers and the population by their personal example. The hygiene conditions within the fortress had sunk desperately, and food was short. In the afternoon of February 5 a powder depot of the St. Antonio battery was struck by a Piedmontese grenade, destroying an entire quarter of Gaeta and causing huge losses among the soldiers and the population. The last truce of the siege was declared in the evening of the following day to rescue the wounded.

The Piedmontese fire was getting increasingly accurate, and the situation for both defenders and inhabitants looked desperate. On February 10 Maria Sophie received a letter from the French empress, saying that the resistance had been prolonged enough to save the Crown's honour. Francis II issued for a capitulation. Cialdini refused to stop the bombardment during the negotiations, and Gaeta suffered new devastations until the capitulation was signed on February 13. The last shells were fired by both the opponents at 18.15 p.m. that day.

The defenders could surrender with their honour preserved.

The first Piedmontese infantry entered Gaeta one day later, exactly when Francis II and his wife consigned themselves to the victors, hailed by the Sicilians soldiers who had remained faithful until the very end. The Kingdom of Two Sicilies, created in the 12th century by the Norman Roger II, ended some days later when the last organized centre of resistance, Civitella del Tronto, surrendered on March 20, 1861.

Casualties amounted to 829 dead and 2,000 wounded for the Sicilians. Two hundred civilians fell during the siege, while the Piedmontese had 46 dead and 321 wounded.
