L’ Adua It was a submarine of the Royal Marina.
Once on duty he was located in Naples, framed in the XXIII submarine squadron. [2]
In the spring months of 1937 he carried out a training journey in the eastern Basin of the Mediterranean, being then employed in training. [2]
In 1939 he was transferred to Cagliari, within the 71st submarine squadron (VII Group) [3] [4]
On June 10, 1940, at the entrance of Italy in the Second World War, the Adua It was already at sea, in the south of the Sardinian coasts (between the Teulada chief and the island La Galite), [4] under the command of the lieutenant of Vascello Giuseppe Roselli Lorenzini. [2] On June 13 he moved to the waters of the Balearics (between Ibiza and Majorca). [4] and subsequently in the Gulf of the Leone, about fifteen miles east of Capo Creus. [3] On June 17, 1940, at night, he identified a destroyer, but he could not take the attack. [2] The next day, in the morning, after sighting a French convoy (five merchanters and two escort units) on the Marseille-Tolone route, and failing to approach precisely because of the escort, attacked the larger transport (a troop transport) With the launch of a single 1800 meters torpedo, warning the outbreak. [3] [2] However, there are no confirmations of damage. [3]
Subsequently, the command of the vessel Luigi Riccardi assumed the command of the unit. [2]
From 22 October 1940 to 12 March 1941 L ‘ Adua He was intended for the training of the students of the Summergible School of Pula, for which he carried out 46 training missions; In this period of time, the lieutenants of Vascello Carlo Todaro and Mario Resio took advantage of the unit. [3] [4]
Back under Riccardi’s command, the submarine was moved to Taranto in mid -March 1941. [3]
From March to May the Adua He was employed in the Gulf of Taranto and along the coasts of Greece, [3] carrying out three unsuccessful missions:
On 10 May he took the basic of Lero. [3]
On June 3, 1941 he stopped – near Capo Littinos, in the Bay of Messaria – a motor bettolina transporting petrol and 72 English soldiers (8 officers and 64 non -commissioned officers and soldiers), fleeing Crete – whose occupation by the troops Germans had just been completed – towards Egypt: the Adua The eight officers took prisoners and forced the boat to return to the island, allowing the capture of the soldiers. [3] [2] [4]
The submarine was then subjected to a three -month maintenance period at the Taranto arsenal. [3]
In mid -September he operated in the waters of Menorca, returning to the base of Cagliari on the 16th. [3]
On September 23, the submarine left Cagliari to disappear lurking (he had to form a barrier with three other submarines) on the route of a British convoy for Malta (“Halberd” operation); More precisely, he positioned himself – on day 26 – near Capo Palos (north of the Spanish city of Cartagena). [3] [2] [5]
The British convoy passed not seen and reached Malta; the submarines, including the Adua , sighted and attacked the British ships on the return route. [5] On September 30, at 3.50, he sighted a group of eleven British destroyers, and attacked them with a foam of four torpedoes, missing them (even if a burst was warned) and moving away with a north route. [3] [2] [5] Shortly after – at 5.25. [3] – He launched the sign of discovery (with which Maricosom was informed, the command of submarines, of the position of the English ships, as well as of the attack) and then disappeared. [2]
It was then known that the submarine had been tracked down by two of the destroyed destroyers, the Gurkha and the Legion (perhaps it was precisely the radio communication with the basis that allows the British ships to find it), which, after detecting it with the ASDIC, had started to bomb it with depth charges: at 10.30, hit, the Adua It had been unable with the whole crew in position 37 ° 10 ‘n and 00 00 ° 56’ and or 36 ° 50 ‘n and 00 00 ° 56’ E. [3] [2] [5] [4]
The commander Riccardi disappeared, 4 other officers, 8 non -commissioned officers, 19 subcapi and 15 sailors. [3] [4]
The submarine had carried out 8 offensive-explosive missions and 16 transfer, for total 8146 miles of navigation on the surface and 1504 in immersion, [2] plus 46 training missions [3] (whose travel is not clarified).
