Formidabile was the

broadside ironclad
, equipped with four 203 mm (8 in) and sixteen 164 mm (6.5 in) guns.

The ship took part in the operation off Lissa in 1866 during the Third Italian War of Independence. There, she silenced the Austrian coastal batteries protecting the main port, but she was too badly damaged to take part in the ensuing Battle of Lissa. The ship's postwar career was limited due to a combination of drastically reduced naval budgets and the appearance of more modern ironclads. Formidabile was used as a training ship starting in 1887; she was discarded in 1903 and broken up for scrap.

Design

Formidabile was 65.8 meters (215 ft 11 in)

screw propeller, with steam supplied by six coal-fired, rectangular fire-tube boilers. The boilers were vented through a single funnel. Her engine produced a top speed of 10 knots (19 km/h; 12 mph) from 1,080 indicated horsepower (810 kW). She could steam for about 1,300 nautical miles (2,400 km; 1,500 mi) at her top speed. To supplement her steam engine, the ship was schooner-rigged.[1]

Formidabile was a

broadside ironclad, carrying all of her guns in the traditional broadside arrangement. She was armed with a main battery of four 203 mm (8 in) guns and sixteen 164 mm (6.5 in) rifled muzzle-loading guns. The ship's wooden hull was sheathed with wrought iron belt armor that was 109 mm (4.3 in) thick.[1]

Service history

Formidabile in 1870

Formidabile was

launched on 1 October 1861 and was completed in May 1862; by this time, the Sardinian fleet had been reformed as the Regia Marina (Royal Navy) of the newly unified Kingdom of Italy.[2] In June 1866, Italy declared war on Austria, as part of the Third Italian War of Independence, which was fought concurrently with the Austro-Prussian War.[3] The Italian fleet commander, Admiral Carlo Pellion di Persano, initially adopted a cautious course of action; he was unwilling to risk battle with the Austrian Navy, despite the fact that the Austrian fleet was much weaker than his own. Persano claimed he was simply waiting on the ironclad ram Affondatore, en route from Britain, but his inaction weakened morale in the fleet, with many of his subordinates openly accusing him of cowardice.[4]

Rear Admiral Wilhelm von Tegetthoff brought the Austrian fleet to Ancona on 27 June, in attempt to draw out the Italians. Persano held a council of war aboard the ironclad Principe di Carignano to determine whether he should sortie to engage Tegetthoff, but by that time, the Austrians had withdrawn, making the decision moot. The Minister of the Navy, Agostino Depretis, urged Persano to act and suggested he capture the island of Lissa, to restore Italian confidence after their defeat at the Battle of Custoza the previous month. On 7 July, Persano left Ancona and conducted a sweep into the Adriatic, but encountered no Austrian ships and returned on the 13th.[5]

Battle of Lissa

On 16 July, Persano took the Italian fleet out of Ancona, bound for Lissa, where they arrived on the 18th. With them, they brought troop transports carrying 3,000 soldiers; the Italian warships began bombarding the Austrian forts on the island, with the intention of landing the soldiers once the fortresses had been silenced. In response, the Austrian Navy sent the fleet under Tegetthoff to attack the Italian ships.

coastal defense ship Varese. After spending the 18th unsuccessfully bombarding the Austrian fortresses, the Italians withdrew late in the day, preparing to launch another attack the following morning. Persano ordered Formidabile to enter the harbor at Vis and attack the Madonna battery, supported by the ironclads Castelfidardo, Ancona, and Principe di Carignano.[7]

Upon entering the small harbor, the Italians found it impossible for the four ships to attack simultaneously, and so Formidabile was left to engage the Madonna battery alone. Following the conclusion of the bombardment, the ship's captain, Simone Antonio Saint-Bon, reported to Persano that his ship had suffered over 50 casualties, and it had been significantly damaged by Austrian fire, though its armor had not been penetrated. Saint-Bon took his battered ship to the west, where he transferred his wounded to a hospital ship. The following day, while Formidabile was with the hospital ship, the Austrian fleet under Tegetthoff appeared. Persano had ordered Formidabile to return to the line, but Saint-Bon informed Persano that his ship was unable to fight, and instead he withdrew to Ancona. The Italians were defeated in the ensuing battle, with the ironclads Re d'Italia and Palestro sunk.[8]

Later career

After the battle, Persano was replaced by Admiral

conscripted to man them were sent home.[10] In addition, Formidabile was rapidly surpassed, first by central battery and then turret ships, which made the first generation of ironclads like Formidabile and her sister obsolete.[11]

As of October 1871, Formidabile was stationed in

naval register and subsequently broken up for scrap.[1][13]
