Italy:
The superstructures of the Italian battleship Conte di Cavour at Taranto, after she sank in shallow water before she could be grounded for the damage suffered by a torpedo hit from a Fairey Swordfish, in December 1940
When the Fleet Air Arm attacked Taranto, one of the battleship that were hit by the torpedoes was the battleship
Conte di Cavour (as one can see from
this map), at 2314 hours. Despite claims that the single torpedo hit (by Lt. Cmd. Williamson, whose Swordfish was taken down by the battleship's 37 mm guns immediately after releasing the weapon), for all the damage it caused, proved that at least on the rebuilt battleships the
infamous Pugliese TDSwas a failure, the torpedo did not hit the side of the ship and said TDS, but instead detonated, thanks to its magnetic detonator,
below the keel, under Turret no. 2 (Turret B in RN terminology), where the only thing that protected the ship was the triple bottom.
The damage suffered was severe, as a hole of roughly 100 square meters (more or less 1076 square feet) was torn open, causing the immediate flooding of the bow magazines and nearby compartments. The condition of the ship was recognized as critical by its commander, who decided to call up the available tugs to have the battleship grounded on a sandbank nearby. However, the admiral commanding the 5a Divisione (Fifth Division, the old battleships),
Bruto Brivonesi (not to be confused for his brother, likewise an admiral,
Bruno Brivonesi) believed that the flooding could be contained without resorting to this measure, and countermanded this order.
After more than four hours of unsuccessfully fighting the floodings, Admiral Brivonesi realized that the battleship seriously risked sinking, and finally agreed to the grounding. However, as the ship was seriously bow-heavy, at 0500 hours in the morning the bow touched the mud much farther from the shore than planned, and in the end the battleship settled into the mud (at a depth of around 17-18 m, 55-60 ft) around 0800, at first taking a severe list to port (40-45°) but then settling almost upright. Of the crew, seventeen men died and there were numerous wounded.
The damage suffered by the old battleship had been comparable to that of its half-sister
Duilio, but in the latter's case the prompt grounding of the ship had preempted its sinking in shallow water, and enabled her to be refloated and repaired in relatively little time.
The salvage of the
Conte di Cavour began in earnest, although with a lesser priority than that granted to the
Littorio and the
Duilio, and it began by removing all removable weights (armament, fire directors, etc.). A "dam" was built around the hull hole to allow the ship to be made watertight again and be refloated, which happened on 22 December 1941. After being drydocked to patch the hull, she would be sent to Trieste to be thoroughly repaired and refitted (it was planned to improve its secondary and AA armament), but work proceeded slowly, and even before the Armistice work was ordered stopped. Captured by the Germans on 11 September 1943, she was sunk on 20 February 1945 during an air attack, after being struck by two bombs.
It has been said that the virtual loss of the
Conte di Cavour at Taranto would, ironically, mirror the loss of its sister, the
Giulio Cesare, when the latter sank in Sevastopol in 1955, after having been ceded to the Soviet Navy. In both cases, the ill-advised intervention of a superior officer who countermanded the sensible orders of the unit commander ended up delaying actions that might have prevented the sinking or, in the latter's case, at least heavy loss of life.
The salvage of the
Conte di Cavour was undertaken mainly for prestige reasons, to make sure that no battleship struck at Taranto could be considered a total loss. However, the resources spent on this obsolescent battleship, whose efficacy against RN battleships was more than questionable and whose use together with the newer
Littorio-class battleships caused more than a few headscratchers, can raise more than a few criticism, compared to the conservative (and in hindsight more sensible) choice of simply raising her, and strip her of what could still be useful, without insisting for a full refit for operational service.
