Italian ironclad Re d'Italia

Design

Main article: Re d'Italia-class ironclad

Re d'Italia was 99.61 m long overall; she had a beam of 16.76 m and an average draft of 6.17 m. She displaced 5610 LT normally and up to 5869 LT at full load. Her hull was built from green wood. She had a crew of 565.

The ship's propulsion system consisted of one single-expansion marine steam engine that drove a single screw propeller. Steam was supplied by four coal-fired, rectangular fire-tube boilers, which were vented through a single funnel located amidships. Her engine produced a top speed of 10.6 to from 1812 to. She could steam for about 1800 nmi at a speed of 10.5 kn. For long-distance travel, Re d'Italia was fitted with three masts and was barque-rigged.

Re d'Italia was a broadside ironclad, and she was armed with a main battery of six 72-pounder 8 in guns and thirty-two 164 mm rifled muzzle-loading guns. The ship was equipped with a spur-shaped ram at the bow. The ship's hull was sheathed with wrought iron armor that was 4.75 in thick. Her rudder and propellers, however, were not protected by her armor.

Service history

Re d'Italia was built by William H. Webb at his shipyard in New York City. She was laid down on 21 November 1861 and launched on 18 April 1863. The ship arrived in Italy in April 1864 and was commissioned into the Italian fleet on 18 September 1864. Less than two years later, 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. 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 , en route from Britain, but his inaction weakened morale in the fleet, with many of his subordinates openly accusing him of cowardice.

Rear Admiral Wilhelm von Tegetthoff brought the Austrian fleet to Ancona on June 27, in attempt to draw out the Italians. At the time, many of the Italian ships were in disarray; several ships did not have their entire armament, and several others had problems with their engines. Re d'Italia had a fire burning in her coal bunkers. Persano held a council of war aboard the ironclad to determine whether he should sortie to engage Tegetthoff, but by that time, the Austrians had withdrawn, making the decision moot.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 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.

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. At that time, Re d'Italia was Persano's flagship in the 2nd Division, along with the ironclad and the coastal defense ship . The Italian 2nd and 3rd Divisions were sent to attack the coastal batteries protecting the town of Vis on 18 July; Re d'Italia, , San Martino, and Palestro were assigned the eastern defenses, while four other ironclads were tasked with suppressing the batteries on the western side. Formidabile was sent to engage Fort San Giorgio at close range while the other ironclads shelled it from afar; one shell from the ironclad detonated the fort's powder magazine, which neutralized the defenses. The success prompted Persano to order several ironclads to attempt to force an entrance into the harbor, but heavy Austrian artillery fire forced him to break off the attempt. After the attack failed, the Italians withdrew late in the day, preparing to launch another attack the following morning.

The next morning, Persano ordered another attack; four ironclads would force the harbor defenses at Vis while Re d'Italia and the rest of the fleet would attempt to suppress the outer fortifications. This assault also failed to neutralize the Austrian coastal fortifications, and two ships were damaged in the fighting. With the day's attacks again having yielded no results, Persano met with his senior officers to discuss options. His chief of staff, d'Amico, and Vacca both suggested a withdrawal owing to the shortage of coal, but Persano ruled that out. He ultimately decided to make another attempt on the 20th. Vacca would take his three ships to patrol to the north-east of the island while the rest of the fleet would again try to land the soldiers.

Before the Italians could begin the attack, but after the fleet had begun to disperse for the landing operation, the dispatch boat arrived, bringing news of Tegetthoff's approach. Persano's fleet was in disarray; the three ships of Admiral Giovanni Vacca's 1st Division were three miles to the northeast from Persano's main force, and three other ironclads were further away to the west. Persano immediately ordered his ships to form up with Vacca's, first in line abreast formation, and then in line ahead formation. Re d'Italia was the fourth ship in the Italian line, behind only Vacca's ships.

Shortly before the action began, Persano decided to leave Re d'Italia and transfer to Affondatore, though none of his subordinates on the other ships were aware of the change. They were thus left to fight as individuals without direction. More dangerously, by stopping Re d'Italia, he allowed a significant gap to open up between Vacca's three ships and the rest of the fleet. Tegetthoff took his fleet through the gap between Vacca's and Persano's ships, though he failed to ram any Italian vessels on the first pass. The Austrians then turned back toward Persano's ships, and took Re d'Italia, San Martino, and Palestro under heavy fire. The Austrian ships concentrated their fire on Re d'Italia, paying particular attention to her stern. In their attempts to ram her, one of the Austrian ships destroyed Re d'Italias rudder, leaving her unmaneuverable.

Re d'Italias captain, Emilio Faà di Bruno, attempted to escape from the melee, but he could only steer his ship using her engines. Blocked by another Austrian ironclad, Faà di Bruno ordered his ship to reverse course. She was almost stopped when she was rammed by the Austrian flagship, . The Austrian ship's ram tore a gaping hole in Re d'Italias hull. She quickly rolled over to port and sank. Out of her crew, only 166 men were saved; the remaining 400 went down with the ship, including Faà di Bruno.
