Turchese was a coastal submarine of the Perla class with a displacement of 680 tons on the surface and 844 submerged.
During the conflict against the Allies (June 10th, 1940, through September 8th, 1943) the boat carried out 32 patrols (mostly in the Strait of Sicily and along the North African coast) and 26 transfer missions, covering 27,904 miles on the surface and 5255 submerged, as well as 95 outings for training or sea trials. It was thus the second Italian submarine for the number of missions carried out in the 1940-1943 conflict, surpassed only by the old H 2 which, however, was used for “second line” tasks in much less dangerous waters.
Seriously damaged by a British aircraft in an episode of “friendly fire” in the aftermath of the armistice, it was never repaired, remaining unused until the end of the war and was subsequent demolition under the conditions of the peace treaty.

May 5th, 1938
Under the command of Lieutenant Francesco Coelli (1), the submarine Turchese took part in the naval magazine “H” organized in the Gulf of Naples for Adolf Hitler’s visit to Italy. Most of the Italian fleet took part in the review: the battleships Giulio Cesare and Conte di Cavour, the seven heavy cruisers of the I and III Divisions, the eleven light cruisers of the II, IV, VII and VIII Divisions, 7 “light explorers” of the “Navigatori” class, 18 destroyers (the Squadrons VII, VIII, IX and X, plus the Borea and the Zeffiro), 30 torpedo boats (the Squadrons IX, X, XI and XII, plus the old Audace, Castelfidardo, Curtatone, Francesco Stocco, Nicola Fabrizi and Giuseppe La Masa and the four “escort notices” of the Orsa class), as many as 85 submarines of the Submarine Squadron under the command of Admiral Antonio Legnani, and 24 MAS (Squadrons IV, V, VIII, IX, X and XI), as well as the training ships Cristoforo Colombo and Amerigo Vespucci, Benito Mussolini’s yacht, the Aurora, the royal ship Savoy and the target ship San Marco.
The Submarine Squadron, under the command of Rear Admiral Antonio Legnani, was the protagonist of one of the most spectacular moments of the parade, in which the 85 boats carried out a series of synchronized maneuvers. First, arranged in two columns, at 1.15 PM they pass opposite direction between the two naval squadrons proceeding on parallel routes. Then, at 1:25 PM, all the submarines made a simultaneous mass dive, proceeded for a short distance submerged and then emerged simultaneously and executed a salvo of eleven shots with their respective guns.
1. Promoted to Commander, Coelli died aboard the Heavy Cruiser Pola on March 3rd, 1941 during the Battle of Matapan.
May 1938
Turchese, part of the XXXIV Submarine Squadron (I Grupsom of La Spezia) along with Medusa, Jasper and Corallo, was among the numerous units (battleships Cesare and Cavour, heavy cruisers Zara, Pola, Fiume, Gorizia, Trento, Trieste and Bolzano, light cruisers Duca degli Abruzzi, Garibaldi, Eugenio di Savoia, Duca d’Aosta, Attendolo, Da Barbiano, Di Giussano, Colleoni, Cadorna, Diaz, Bande Nere, twenty destroyers of Squadrons VII, VIII, IX and X, 54 submarines of Squadrons XI, XII, XIII, XIV, XV, XXI, XXXIV, XLI, XLII) concentrated in Genoa for another naval review organized on the occasion of Benito Mussolini’s official visit to the city, the first in twelve years.
In his speech to the Genoese on 14 May, Mussolini declared: “… The guidelines of our policy are clear: we want peace, peace with everyone. (…) But peace, to be sure, must be armed. That is why I wanted the whole fleet to gather in Genoa: to show you and the Italians of the two most continental regions, which are Piedmont and Lombardy, what our real strength is on the sea. We want peace, but we must be ready with all our might to defend it, especially when we hear speeches, even from across the Atlantic, on which we must reflect. It is perhaps out of the question that the so-called great democracies are really preparing for a war of doctrines. However, it is good to know that, in this case, totalitarian states will immediately block and march to the end.“
The fleet remained in Genoa until the end of the month, open to visits by the civilian population: a total of 650,000 visitors flocked to see it, of which 430,000 were Genoese and 220,000 from the rest of Liguria, Piedmont, and Lombardy.
June 19th, 1938

October 15th, 1938
Turchese was assigned to the submarine Command School.
Spring 1939
Turchese was deployed in Cagliari, as part of the LXXII Submarine Squadron along with Diapro, Coralllo and Medusa.
January 1st, 1940
Lieutenant commander Gustavo Miniero (1), 33, from Gragnano, took command of Turchese.
- Promoted to Commander, Miniero died on January 5th, 1942 aboard the submarine Ammiraglio Saint Bon.
June 9, 1940
Under the command of Lieutenant Miniero, Turchese sailed from Cagliari at 10.02 PM to form a barrage on the meridian of Capo Teulada, along with Adua, Axum and Aradam. Turchese, specifically, patrolling 35 miles south of Cape Teulada.
June 10th, 1940
Upon Italy’s entry into the World War II, Turchese was part of the LXXII Submarine Squadron based in Cagliari, along with Diaspo, Corallo, and Medusa.
June 13th, 1940
Tuirchse received orders to move to the Gulf of Lion, after which the boat patrolled the waters 15 miles east of Cape Creus until the evening of the 19th, in search of French and British merchant traffic.
June 21st, 1940
At 10:15 AM, the crew sighted three small military units from 20 km away in quadrant 0261, northeast of the Balearic Islands. Approaching up to 14 km, Captain Miniero realized that he was dealing with a large enemy formation thus gave up the chase at 11.48 AM.
Probably, the units sighted were the French destroyers of the 8éme Division de Contre-Torpilleurs, the fastest warships in the world.
At 10.05 PM Turchese returned to Cagliari, after having covered 1,052 miles.
July 3rd, 1940
The boat sailed from Cagliari at 2.16 PM, under the command of Lieutenant Gustavo Miniero, to lay in ambush in position 37°54′ N and 07°40′ E, forming a patrol line between Bona and Cap de Fer with Aradam (which sailed along with Turchese), Alagi and Axum.
July 6th, 1940
The boat returned to Cagliari at noon, after having covered 262 miles.
July 9th, 1940
Still under the command of Lieutenant Gustavo Miniero, Turchese sailed from Cagliari at 00.57 for a patrol in position 37°50′ N and 09°40′ E, between the island of Galite and Tunisia.
July 12th, 1940
At 2.25 AM, during the return navigation, the officer of the watch sighted an illuminated ship in position 38°24′ N and 09°19′ E. Turchese approached using the electric motors, to remain silent and avoid revealing its presence. The unknown ship behaves strangely (it seems to be stationary), so much so that it was believed that it is not a neutral ship – as it should be, given the lights on – but an enemy ship engaged in laying mines.
At 3:25 AM, Turchese launched a 533 mm torpedo from the forward tubes from only 500 meters away. The phosphorescent wake pointed straight to the center of the target, but the torpedo passed under the hull without exploding. At 3:26 AM a second torpedo was launched, again 533 mm and again 500 meters, but this too passed under the hull of the unknown ship. Commander Miniero wanted to try again with a third torpedo, and open fire with the cannon, but at 3.35 AM Turchese violently hit a metal object, at 3.38 AM a second collision occurs, more violent than the first. At 4:10 AM, the submarine broke contact and moved away (according to another source, the unknown ship would have been able to disengage thanks to the increased speed). At 11.05 AM Turchese returned to Cagliari, after having covered 354 miles.
August 1st, 1940
Still under the command of Lieutenant Gustavo Miniero, Turchese sailed from Cagliari at one o’clock in the morning for a patrol south of the Balearic Islands, in position 37°25′ N and 06°30′ E. It was to form a barrage along with the submarines Argo, Scirè, Neghelli, Medusa, Axum and Diaspro, arranged in two lines of three and four units spaced ten miles apart (while the distance between two submarines of the same line was twenty miles) north of Cape Bougaroni. The formation of the barrage was ordered by Supermarina following the report of the exit from Gibraltar of the British Force H (which sailed with the aircraft carriers H.M.S. Argus and H.M.S. Ark Royal, the battlecruiser H.M.S. Hood, the light cruiser H.M.S. Enterprise and the destroyers H.M.S. Faulknor, H.M.S. Foxhound, H.M.S. Foresight, H.M.S. Forester, H.M.S. Encounter, H.M.S. Gallant, H.M.S. Greyhound and H.M.S. Hotspur for operations “Hurry” and “Crush”, consisting respectively of sending to Malta twelve fighters launched by H.M.S. Argus and an air attack against Cagliari by planes that took off from H.M.S. Ark Royal).
Turchese was part of the line of four units, together with Diaspro, Axum and Medusa (which after two days had to be replaced by the submarine Luciano Manara following a breakdown). Force H, however, would move north of the area where the submarines were deployed, thus they were not able to attack.

January 9th, 1941
At 7:25 AM, the Greek submarine Triton (Lieutenant Commander Dyonisios Zeppos) unsuccessfully attacked a submarine west of Othoni, in the Otranto Channel. It is possible that the submarine attacked was Turchese, which for its part, however, did not notice the attack.

April 30rd, 1941
At 5:27 PM, Turchese, engaged in hydrophone surveillance while submerged, when it was suddenly shaken by two explosions, which were attributed to aircraft bombs. At 6:42 PM, eight more explosions occurred, and then more until 7:40 PM.
They were not aircraft bombs but depth charges, dropped in position 32°59′ N and 27°52′ E by the British destroyers H.M.S Jaguar and H.M.S. Juno, which wrongly believe that they have sunk the attacked submarine (H.M.S. Juno will have five dead and eleven wounded among the crew due to the premature explosion of a depth charge). To escape the hunt, Turchese descended to a depth of 90-95 meters.
May 1st, 1941

June 5th, 1941
At 8:43 PM, twenty miles southwest of Cape Krio, a submarine was sighted two thousand yards away. Captain Di Domenico decided to dive as a precaution, but during the diving phase the boat was identified as Italian. It was in fact Smeraldo, which in turn recognized the other unit as Italian (although it was wrong about the class, believing to be the Fisalia) and carried out the recognition signals. Subsequently, Turchese headed to Taranto due to engine problems.

September 23rd, 1941
Turchese sailed from Cagliari at 7:00 PM, under the command of Lieutenant Di Domenico, for a patrol south of the Balearic Islands, between Cape Palos and Cape Caxine (south/southwest of Ibiza), in an area bounded by the meridians 00°20′ E and 00°40′ E and the parallels 36°50′ N (or 36°30′ N) and 37°30′ N. It was part of a barrage together with the Adua, in contrast to the British operation ‘Halberd’. As part of this operation, Force H lefty Gibraltar, with the battleships H.M.S. Prince of Wales, H.M.S. Rodney and H.M.S. Nelson, the aircraft carrier H.M.S. Ark Royal and the destroyers H.M.S. Duncan, H.M.S. Fury, H.M.S. Lance, H.M.S. Legion, H.M.S. Lively, H.M.S. Gurkha, H.M.S. Zulu, Isaac Sweers (Dutch), Garland (Polish) and Piorun (Polish). The formation was divided by the British into various sub-groups, which departed at different times between September 24th and 25th. The purpose was to protect the navigation to Malta of a convoy with supplies (WS. 11X, formed by the military tanker Breconshire and the cargo ships Ajax, City of Lincoln, City of Calcutta, Clan MacDonald, Clan Ferguson, Rowallan Castle, Imperial Star and Dunedin Star with a combined cargo of 81,000 tons of supplies and the direct escort of the light cruisers H.M.S. Edinburgh, H.M.S. Sheffield, H.M.S. Euryalus, H.M.S. Kenya and H.M.S. Hermione and the destroyers H.M.S. Cossack, H.M.S. Farndale, H.M.S. Foresight, H.M.S. Forester, H.M.S. Heythrop, H.M.S. Laforey, H.M.S. Lightning and H.M.S. Oribi of Force X), which would take place at the same time as the navigation of another convoy (three unloaded merchant ships, escorted by a corvette) from Malta to Gibraltar and with a diversionary action by the Mediterranean Fleet in the eastern Mediterranean.
The departure of Force H in several groups, and the routes followed by them until the meeting (which took place on the morning of September 27th, one hundred miles south of Cagliari), deceived the Italian commands, who mistakenly believed that the purpose of the operation was a naval bombardment against targets on the coasts of the Peninsula (as attested by the “Notiziario 73” of “Maristat Informazioni”, on the morning of September 25th, according to which “The purpose of the mission would be retaliation against the Italian coasts”). To counter this hypothetical bombardment, Supermarina sent four submarines east of the Balearic Islands, three more southwest of Sardinia, three south/southwest of Ibiza and five in the Ligurian Sea. Turchese, Adua, Dandolo, Squalo, Delfino and Fratelli Bandiera were sent north of Cape Ferrat, Narvalo north of Cape Bon.
Turchese, Adua and Dandolo reached the assigned areas only after the British formation has already crossed them. Maricosom, as a consequence, ordered all submarines to move further south, attempting to intercept the British forces (whose real objective was meanwhile understood by Supermarina on the morning of the 27th, when news of the existence of a convoy bound for Malta arrived) during the re-entry phase, communicating at 8.45 PM on the 27th: “Enemy naval force already attacked and damaged by ARMERA (STOP) In search and attack act with maximum commitment and precision to inflict to the enemy further and more serious damage possible (STOP) I am sure that you will prove worthy of the trust that the Navy places in you (STOP)”. But even these new orders will not bring results.
Equally unsuccessful was the departure to sea of the battle squadron under the command of Admiral Angelo Iachino (battleships Littorio and Vittorio Veneto, heavy cruisers Trento, Trieste and Gorizia, light cruisers Muzio Attendolo and Luigi di Savoia Duca degli Abruzzi, destroyers Granatiere, Bersagliere, Fuciliere, Ascari, Lanciere, Cuirassier, Carabiniere, Folgore, Maestrale, Grecale, Scirocco, Vincenzo Gioberti, Nicoloso Da Recco and Emanuele Pessagno).
September 30th, 1941
At 5:03 AM, a message was received reporting the sighting by the Adua, at 3:50 AM, of a group of eleven destroyers, which, however, given their position and course, would pass much further north than the position of Turchese.
At 10.17 AM smoke was sighted from 14,000 meters, in position 36°49′ N and 00°24′ E. Turchese maneuvered to approach, and at 10.39 AM, having dropped the distance to 6,000 meters, managed to distinguish two Arethusa-class cruisers and two destroyers. At 11:10 AM, while Turchese was at a depth of 19 meters, six explosions were detected quite close. Commander Di Domenico decides to descend to 40 meters. At 1:39 PM, the hydrophones no longer picked up any noise.
The destroyers sighted by Turchese were probably the British H.M.S. Legion and H.M.S. Gurkha, which formed the advanced screen of Force H returning from operation “Halberd”. in a few hours they would sink the Adua.
October 2nd, 1941
At 6.50 AM a submarine, probably Italian, was sighted from 2,000 meters away, in position 37°15′ N and 03°12′ E. Given the poor visibility, however, Turchese maneuvers as a precaution to get away.
October 4th, 1941
The boat returned to Cagliari at 10.25 PM, after having covered 1,258 miles.
October 15th, 1941

December 19th, 1941
At 9.40 AM, a German submarine (possibly U 74) was sighted 3,000 meters away, in position 38°05′ N and 07°47′ E, which made an indecipherable signal. Turchese continued on its course.
December 21st, 1941

December 23rd, 1941
At 2:45 PM, ship noises were picked up on the hydrophone, on a 248° bearing. However, their direction varied considerably. Turchese headed towards them, and at 5.05 PM, in position 37°21′ N and 06°26′ E (off Cape Bougaroni), Turchese sighted two cruisers identified as of the Newcastle class and four destroyers believed to be of the Jervis class, sailing southwest at 25 knots, 12 km away; It send the discovery signal. However, it could not get closer than 7,000 meters.
The ships sighted were probably the British light cruiser H.M.S. Dido and the destroyers H.M.S. Zulu, H.M.S. Gurkha, H.M.S. Arrow, H.M.S. Foxhound and H.M.A.S. Nestor, the latter Australian.
December 25th, 1941

January 1st, 1942
At 8 PM Turchese sailed from Cagliari under the command of Lieutenant Di Domenico, to form a barrage between 60 and 100 miles south of Malta (line passing through point 35°00′ N and 13°00′ E) together with Alagi, Aradam and Axum, to protect the convoys sailing between Italy and Libya. Their task was to spot and attack any British naval forces that might take to the sea to counter Operation M. 43, consisting of sending a large convoy of supplies to Libya. In total, as many as eleven submarines (Turchese, Aradam, Platino, Onice, Galatea, Beilul, Delfino, Alagi, Axum, Zaffiro and Dessiè) were deployed in ambush on the probable routes that a British naval formation could take; one group (Turchese, Aradam, Axum, Platino, Onice, Alagi and Delfino) was deployed to the east of Malta, against possible arrivals from this island, another (Beilul, Galatea and Dessiè) further east, between Crete and Cyrenaica, on the route that would follow a formation that takes the sea from Alexandria. The submarines had an offensive-exploratory assignment during the day and a total offensive at night.
Turchese, specifically, was assigned a patrol area bounded by the meridians 14°00′ E and 14°40′ E and the parallels 34°20′ N and 34°40′ N. (Another source speaks of a barrage between Tobruk and Ras Aamer, together with Ametista and Galatea).
No British naval force would be able to attack the convoy, as the Mediterranean Fleet had been reduced to a minimum as a result of the losses inflicted at the end of 1941 by mines, Italian assault craft and German submarines (a situation of which, however, Rome was not aware, so as to lead to extreme precautionary measures such as this deployment of underwater units to protect the navigation of an important convoy such as “M. 43”); The convoy reached its destination unscathed, bringing to Libya 15,379 tons of fuel, 2,417 tons of ammunition, 10,242 tons of various materials, 144 tanks, 520 vehicles and 901 officers, non-commissioned officers and soldiers.

March 27th, 1942
The boat set sail from Cagliari at 10.05 PM, under the command of Lieutenant Di Domenico, to form a barrage off Capo Bougaroni together with the Aradam (and, according to another source, Narvalo and Santorre Santarosa). It was assigned a patrol area bounded by the meridians 05°20′ E and 06°20′ E and the parallels 37°10′ N and 37°20′ N; The task of the submarines was to intercept Force H (under the command of Admiral Neville Syfret), which left Gibraltar and headed east, should it go there. However, the British formation, whose purpose is to launch aircraft intended to reinforce the Malta squadrons (this is Operation “Picket II”. The aircraft carriers H.M.S. Eagle and H.M.S. Argus set sail from Gibraltar on March 27th with the escort of the battleship H.M.S. Malaya, the light cruiser H.M.S. Hermione and the destroyers H.M.S. Active, H.M.S. Anthony, H.M.S. Blankney, H.M.S. Croome, H.M.S. Duncan, H.M.S. Exmoor, H.M.S. Laforey, H.M.S. Lightning and H.M.S. Wishart, launching on March 29th 8 Supermarine Spitfire fighters that reached Malta, while it will not be possible to launch, as planned, 6 Fairey Albacore torpedo bombers).
March 30th, 1942
At 5:12 PM, while Turchese was heading to intercept an enemy cruiser reported at 8:09 PM the previous day southwest of La Galite, an aircraft was sighted 7,000 meters away, in position 37°25′ N and 06°29′ E. The submarine dove. On board, it was believed that the cruiser passed about 10 miles away.
April 1st, 1942
At three o’clock in the morning, a large seaplane, identified as a PBY Catalina, was sighted in position 37°40′ N and 06°26′ E, 1,000 meters away. Turchese dove precipitously as five bombs explode, causing only minor damage.
The attacker was indeed a Catalina, the “J” aircraft (serial number AJ. 160) of the 202nd Squadron of the R.A.F., piloted by Lieutenant I. F. Edgar, which detected Turchese on radar from 8 miles and then also sighted it optically on route 075°, dropping its bombs (eight depth charges, one of which, however, did not drop due to a failure) from an altitude of just over 20 meters while the submarine was diving. Edgar later reported that he had spotted a large patch of naphtha at the site of the attack.

At 9:41 PM, Turchese was informed that a British naval force had left Gibraltar that morning: Force H (aircraft carrier H.M.S. Furious, anti-aircraft cruisers H.M.S. Aurora and H.M.S. Charybdis, destroyers H.M.S. Laforey, H.M.S. Lookout, H.M.S. Bicester, H.M.S. Eskimo, H.M.S. Venomous, and H.M.S. Tartar), engaged in Operation “Baritone”, consisting of the launch of 29 Spitfire V fighters bound for Malta. In addition to Turchese, the submarines Brin, Corallo, Emo, Topazio, and Axum are also directed against it, to form a submarine barrage south of the Balearic Islands.
Turchese moved to the southern end of its patrol sector and went into hydrophone listening, but to no avail. None of the submarines encountered the British units, which moved north of Algiers to carry out the launch and then returned to base.
October 29th, 1942
At 11 AM, the boat received orders from Maricosom to move southwest of Cape Palos, but again there were no sightings.
October 30th, 1942
At 12.52 PM, in position 38°50′ N and 03°16′ E, a steamer was sighted sailing southwards, from 13 km away; Commander Asquini believed that the ship belongs to Vichy France. At 6:00 PM another steamer was sighted heading south, from 11 km away, in position 38°50′ N and 04°02′ E. This was also considered French.
November 1st, 1942
Turchese returned to Trapani at 2.40 PM, after having covered 1823 miles.
November 7th, 1942
Under the command of Lieutenant Giandaniele Asquini, Turchese sailed from Trapani at one o’clock in the morning for a patrol off Bizerte, in position 37°12′ N and 08°00′ E (for another source, 37°30′ N and 10°00′ E, and shortly after 37°20′ N and 07°50′ E), to counter the Anglo-American landings in French North Africa (operation “Torch”). More than 800 British and American ships of all types are sailing towards the coasts of Morocco and Algeria, to land troops to open a second front in North Africa, at the same time as the breakthrough operated by the British Eighth Army in Egypt, at El Alamein.
Supermarina, informed of the sighting of large Anglo-American naval forces sailing westward from Gibraltar, correctly guessed that the Allies probably wanted to attempt a landing in North Africa, although Turchese did not completely exclude the possibility of a convoy heading to Malta.
In total, Maricosom – on the basis of an order from Supermarina, transmitted at 10.06 PM on November 6th – sent twenty-one submarines to the western and central-western Mediterranean, to counter the enemy operation: twelve submarines of the VII Grupsom (Acciaio, Argento, Asteria, Aradam, Brin, Dandolo, Emo, Galatea, Mocenigo, Platino, Porfido, Velella) were deployed west of the island of La Galite (zone “A”), seven submarines of the VIII Grupsom (Bronze, Alagi, Avorio, Corallo, Diaspro, Turchese) were sent north of Bizerte (zone “B”), and two others (Axum and Topazio) in an advanced position between Algeria and the Balearic Islands. These positions turned out to be too far from the actual landing zones (Oran and Algiers), but they were not modified, because the German commanders mistakenly believed that the Allies could attempt further landings in Tunisia as well (in which case the Italian submarines would be in an ideal position).
At 3:31 PM Maricosom (the Submarine Squadron Command) informed all submarines lurking in the western Mediterranean of the position of a British naval squadron and an enemy convoy, reported at 10:40 AM. At 8:07 PM the Submarine Squadron Command reported the position of two convoys sighted on two separate occasions, both heading east and consisting of merchant ships escorted by battleships, aircraft carriers, cruisers, and escort ships.
November 8th, 1942
The landings began: 500 Anglo-American transport ships, escorted by 350 warships of all kinds, land a total of 107,000 soldiers on the coasts of Algeria. Since these operations took place in the areas of Algiers and Oran, the Italian submarines were too far east to intervene. Also, since the German commanders believed that the Allies could make further landings further east, towards Tunisia, it was initially decided to leave the submarines where they were.
At 5:58 PM, north of Bizerte, Turchese sighted a submarine that was identified as the Bronzo. Both boats pulled over to get away, to avoid accidents.
November 9th, 1942
At 7.30 AM, in position 37°18′ N and 08°40′ E, a French ship of 2,000 tons was sighted, from 4,500 meters away.
November 11th, 1942
At 16:45 a submarine was sighted in position 37°08′ N and 07°58′ E and was identified as the Aradam.
November 13th, 1942
At 7:45 AM, an aircraft was sighted in position 37°58′ N and 10°06′ E, 4,000 meters away. Turchese dove to escape an attack; then it headed back to the base, passing through the conventional point T.3. The boat arrived in Cagliari at 9.10 PM, after having covered 741 miles.

December 3rd, 1942
At 7:02 AM, Turchese sighted two steamers escorted by a torpedo boat off Cape Senetosa, heading north; However, the torpedo boat was identified as an Italian unit of the “Tre Pipe” type, so no offensive action was taken. At 10.10 PM Turchese returned to La Maddalena after having covered 262 miles.

May 25th, 1943
At 11:35 AM the boat sighted a formation of four-engine bombers flying eastwards, in the Strait of Messina, and dove to avoid them. The planes spotted it and attacked it while it was submerged, forcing it to zigzag at top speed as several bombs fell into the sea about 900 meters aft.
Back on the surface, at 12:09 PM it sighted another formation of four-engine planes flying eastwards. Again, it dove with a crash dive to a depth of 70 meters, while several explosions of depth charges were heard in the distance.
Returning once again to the surface, at 1.34 PM Turchese sighted a third group of four-engine aircraft, this time flying southwards. Again, it dove precipitously, hearing the explosions of nearby bombs (but probably not directed at it) at 1:38 PM and 1:40 PM

July 1st, 1943
At 9:15 AM, in position 38°20′ N and 07°28′ E, a large air formation was sighted flying eastwards and the submarine dove to avoid being attacked.
July 2nd, 1943
At 7:58 PM Turchese received orders to go up to the parallel 37°20′ N, between 36°40′ N and 07°40′ E, and then return to the previously assigned sector.
July 6th, 1943
At 12:55 PM Turchese received orders to move 10 miles to the east, and then to reach the parallel 37°50′ N by dawn on the 7th. It then moved westwards, from meridian 08°10′ E to that of Cap de Fer (07°10′ E) on the parallel 37°20′ N, a transfer that took place late due to engine problems, and then returned to the original ambush area at dawn on the 8th.
The assignment was to form a preventive barrage to the south of Sardinia, in contrast to a possible Anglo-American landing (which will then take place in Sicily), together with Giada, Alagi, Argento, Nereide, Nichelio, Platino, and Diaspro.
July 10th, 1943
At 2:15 AM Turchese received the order, issued at 00:15 AM, to execute the “Zeta” plan and reach quadrant 96. At 2:25 PM the boat received a new message, transmitted at 11:41 AM, ordering it to reach zone 172 immediately.
July 11th, 1943
At 00.13 Turchese received an order (transmitted at 10.13 PM the previous evening) to reach zone 83 (east coast of Sicily) passing through point 39°00′ N and 15°00′ E and through the conventional point M 3 (off Capo Vaticano).
At 5:22 AM the boat sighted a twin-engine aircraft flying at low altitude with a south-easterly course, in position 38°20′ N and 09°25′ E, and dovew as a precaution. Back on the surface, at 9.08 AM (in 38°20′ N and 09°25′ E) the crew sighted another plane flying southwards. Again, Turchese submerged; at 8.22 PM (position 38°24′ N and 10°10′ E) a third aircraft was sighted flying southeastwards, and once again the boat dove.
At 9:10 PM, yet another new order was received, transmitted at 6:40 PM to move to zone 81; but at 9.32 the yet another plane was sighted, flying northwestwards, in position 38°25′ N and 10°12′ E, and Turchese dove yet another time.
July 12th, 1943
At 4:28 AM, in position 38°43′ N and 11°35′ E, another plane was sighted: another dive, repeated at 10:50 AM following the sighting of a second aircraft with a westerly course.
July 13th, 1943
Yet another sighting of an aircraft, at 3.50 AM, in position 38°48′ N and 12°30′ E: again, Turchese had to dive.
July 14th, 1943
At 00:07 Turchese received orders from Maricosom to move to the northern half of quadrant 80 but had to abandon the mission due to a breakdown. At 5.13 AM the boat dove following the sighting of an aircraft in position 39°00′ N and 13°20′ E.
July 16th, 1943
The boat arrived in Naples at 6.45 AM, after having covered 1,300.5 miles. At 11.05 AM it left to move to Castellammare di Stabia, where it arrived at 12.50 PM, after having covered 13.3 miles.
July 30rd, 1943
Departure from Castellammare di Stabia for sea trials, from 7.20 AM to 10.15 Am travelling 10 miles. At 8.47 PM, still under the command of Lieutenant Galzigna, the boat left Castellammare to move to La Maddalena.
July 31st, 1943
At 2:20 AM, flares were sighted about 2,000 meters away; Turchese dove as a precautionary measure.
August 2nd, 1943
Turchese arrived in La Maddalena at 7.20 AM, after having covered 257 miles, and left at 12.15 PM to move to Mezzoschifo, where he arrived at 1.55 PM, after another 2 miles.

Turchese sailed from Bonifacio at 5.20 AM, under the command of Lieutenant Eugenio Parodi, to move to Villa Marina (on the island of Santo Stefano), where it arrived at 7.59 AM, after traveling 24 miles.
September 7th, 1943
At 3.15 PM (or 1.15 PM) Turchese (Lieutenant Eugenio Parodi) set sail from Villa Marina together with the similar submarine Topazio, for a patrol in the gulfs of Paola and Gaeta. Both submarines, together with Diaspro and Marea, were to form a barrage in the Gulf of Salerno, in contrast to the imminent Anglo-American landing (operation “Avalanche”). Eight other submarines (Brin, Giada, Galatea, Platino, Nichelio, Alagi, Axum, and Velella) complete the anti-landing screen in the Lower Tyrrhenian Sea, along the Tyrrhenian coasts of Campania and Calabria between Paola and Gaeta, while ten (Onice, Settembrini, Vortece, Zoea, Bragadin, Squalo, Menotti, Bandiera, Jalea, and Manara) were deployed in the Ionian Sea along the eastern coasts of Sicily and Calabria. All executed within the framework of the “Zeta” Plan: Supermarina ordered its activation by Maricosom following the sighting in the Lower Tyrrhenian Sea by German air reconnaissance, on the evening of September 7th, of the Allied landing fleet heading towards Salerno.
At 4 PM, off the coast of La Maddalena, Turchese was accidentally targeted by a coastal battery, which fired three salvos without hitting; The shots fell short of about 200 meters.
September 8th, 1943
The armistice between Italy and the Allies was announced: Maricosom ordered all submarines to cease hostilities, immediately dive to a depth of 80 meters and resurface at eight o’clock in the morning of September 9th, and then remain on the surface flying the Italian flag and a black pennant on the periscope, waiting for further instructions. Subsequently, the order was given to head towards Bona, Algeria (for submarines lurking east of Sicily, towards other ports under Allied control such as Malta, Brindisi, and Augusta), keeping the signs of recognition clearly visible.
September 9th, 1943
Interrupted the mission as ordered, Turchese moved from its ambush position south of Sardinia, at 12.21 meeting Topazio (lieutenant Pier Vittorio Casarini) and Marea (sub-lieutenant Attilio Russo), and shortly afterwards the Diaspro (lieutenant Alberto Donato) to form a group. The respective commanders began “discussing” the situation by means of light signals made with the small flashes of light projectors supplied to each submarine (for another version, the “discussion” between the commanders would have taken place by means of megaphones, from their respective cunning towers, given the short distance).
Later, all four of them gather aboard the Diaspro to decide what to do. There are conflicting versions of the outcome of this meeting: according to various authors (including Achille Rastelli and Giuliano Manzari) this first meeting was followed by others on the mornings of September 10th and 11th, and in the end each of the commanders made a different decision. Marea to sail for Bona, Diaspro for Cagliari (assuming there were no German troops), Topazio to the north and Turchese to reach neutral Spain, more precisely the Balearic Islands (which, however, was not confirmed by Turchese’s report, according to which the submarine initially headed towards the 42nd parallel and then towards Bona).
According to the Marea’s report, however, at the end of the meeting the four commanders decided by mutual agreement to aim for Bona, sailing together and waiting for other submarines; the four submarines remained reunited or at least in sight of each other until the evening of the 10th (according to the Marea report, however, the latter and the Diaspro lost sight of Turchese and Topazio as early as 10.30 PM on the 9th, and then lost sight of each other as well). From ten o’clock on September 9th, Turchese sails towards the 42nd parallel.
September 10th, 1943
Turchese and Topazio separated at the Anzio parallel, slightly east of the 11° E parallel. At eight o’clock in the morning, Commander Parodi decided to go directly to Bona.
September 11th, 1943
At 9:27 PM, Turchese was attacked off Bona by an aircraft that was identified as a German Junkers Ju 88 bomber. The bombs that fell closer ended up in the water 6 meters from the bow, portside, exploding underwater at a depth of 10 meters. The explosions cause serious damage to the submarine, knocking out the left diesel engine (for another version, both engines, making it impossible to continue navigation).
The attacking aircraft was not German, but British: a Lockheed Hudson bomber of the 500th Squadron of the Royal Air Force, the “O” aircraft of Second Lieutenant G. M. Shires. Sighting the submarine, and doubtful of its nationality, Lieutenant Shires flew over it twice circling, throwing on the second lap the colors agreed for that day as a signal of recognition. Having received no response, he went on the attack, aiming at the submarine from the opposite direction to that of the Moon (from the starboard bow) and launching a salvo of four depth charges, which fell into the sea astride the cunning tower (according to a source, while the submarine was diving). After the attack, Lieutenant Shires watched the submarine dive astern. Half an hour later, he received orders from the base not to attack unless the boat took hostile action.
September 12th, 1943
In the late afternoon, Turchese encounters a British convoy and was taken in tow by the British armed trawler Stroma.
September 13th, 1943
The damaged Turchese reached Bona at 00:02, in tow of the Stroma, after covering 695 miles. The misunderstanding of which Turchese was the victim extends, with tragic consequences, to Topazio as well. Turchese, in fact, was not the only Italian submarine to be mistakenly attacked by British planes: on the morning of September 12th, Topazio, mistaken by a Bristol Blenheim for a German U-boat, was bombed, and sunk by the latter south of Sardinia.
Most of the crew, fifteen or twenty men, survived the sinking: the British Commands initially sent air and naval vessels to the site to recover them, but recalled them following the news that Turchese had been damaged by an air attack and was sailing towards Bona, mistakenly believing that the submarine attacked by the Blenheim was indeed Turchese. and that the pilot’s assertion that he sank it was the result of a mistaken appreciation. The result of this incredible sequence of errors and misunderstandings will be that no one will come to the rescue of the castaways of the Topazio, of which there will be, consequently, no survivor.
September 14th, 1943
Still under the command of Lieutenant Eugenio Parodi, Turchese sailed from Bona at 1.30 PM to Malta, in tow of the submarine Marea and together with the submarines Alagi, Giada, Galatea, Brin, Menotti and Platino, which converged in Bona following the armistice. The group was escorted by the British destroyer H.M.S. Isis.
A few hours after the departure, however, the tow cable snapped, and Turchese had to be towed back to Bona by a British ship, arriving there at 10:00 PM, after having traveled thirty miles. It then remained under repair in Bona, where the work was completed on September 24th.
September 27th, 1943
Turchese left Bona at 5.21 PM, still under the command of Lieutenant Parodi, to move to Malta. After a few hours, however, the engines failed, which forced the boat to be towed back to port.
September 28th, 1943
Turchese returned to Bona at 7.30 AM, after covering 59 miles, in tow of a British unit.
October 1st, 1943
Turchese left Bona in tow at 4.30 PM, to move to Bizerte. The commander was still Lieutenant Parodi.
October 2nd, 1943
The boat arrived in Bizerte at 5:15 PM, after traveling 123 miles.
October 4th, 1943
The boat left Bizerte at 11.30 AM, under the command of Lieutenant Parodi, for the third attempt to move to Malta. This time it was in tow of the British armed trawler Goth, together with the harbor tug C.T. 13, the motor launches ML 480 and HDML 1243 and the armed fishing vessel HMS Tango, in a convoy of three merchant vessels.
October 6th, 1943
Turchese, finally, arrived in Malta at 10.30 AM, after having covered 251 miles. It was the twenty-third and last Italian submarine to reach the island after the armistice. Turchese went to moor in Marsa Scirocco, under the command of the battleship Giulio Cesare, joining the submarines Atropo, Axum, Bandiera, Bragadin, Corridoni, Giada, Marea, Nichelio, Settembrini and Vortece, moored there since September.
November 27th, 1943
Still under the command of Lieutenant Parodi, and once again in tow (this time, of the corvette Chimera), Turchese left Malta at 3.30 PM to return to Italy. It was the last Italian submarine to leave the island. On the same date, the second chief torpedoman Giuseppe Da Rold, 22 years old, from Belluno, died in the metropolitan area.
November 28, 1943
Turchese arrived in Augusta at 9:30 AM, after traveling 117 miles.
December 11th, 1943
Lieutenant Parodi was replaced by Second Lieutenant Giorgio Mogni, 28, from Savignano Irpino.
March 11, 1944
Under the command of sub-lieutenant Giorgio Mogni, Turchese left Augusta in tow of the torpedo boat Monzambano to move to Brindisi.
March 12th, 1944
Turchese arrived in Brindisi at 7.45 PM, after covering 335 miles. There it entered the shipyard for long renovation work (according to another source, it was laid up there).
March 31st, 1944
Sub-lieutenant Mogni was replaced by Lieutenant Commander Renato Frascolla, 33, from Taranto.
September 13th, 1944
Lieutenant Commander Frascolla was replaced by Marco Revedin, 33 years old, from Bologna.
Lieutenant Commander Marco Revedin
(Collection Giovanni Pinna)
November 22nd, 1944
Lieutenant Commander Revedin handed over command of Turchese to Lieutenant Emilio Botta, 26, from Foggia, who held it until the following August.
June 22nd, 1945
Turchese left Brindisi at 6.05 AM, under the command of Lieutenant Emilio Botta, to move to Naples.
June 23rd, 1945
Turchese arrived in Naples at eight o’clock in the morning, after having covered 450 miles. It then remained in the reserve until the end of hostilities.

Turchese was removed from the Navy rosters, as for the peace treaty requirements, and later demolished.
Another image of the remains of Italian submarines decommissioned in Taranto in February 1947: Turchese is at the far right, in the dock overlooking the Caserma Farinati (Farinati Barracks)
(STORIA militare)
According to Vittorio Iovino, a sailor in the Navy from 1949 to 1951, after the decommissioning Turchese was used for some time as a fuel oil depot, at the same time being used clandestinely for the training of submariners: “the conning tower had been removed and the boat was officially intended as a fuel depot. But we made up for it and built the part of the conning tower with sheet metal so that it would be all efficient to be able to continue going out to sea. The Americans knew everything, but they turned a blind eye, and we were able to go out to sea again for the exercises.” However, there is no trace of such use in any publication, and it seems more likely that Iovino misremembered the name of the submarine in question (two other submarines, Giada and Vortice, were in fact actually used clandestinely for training, while officially they had been downgraded to charging pontoons, in the period between the signing of the Paris peace treaty, which prohibited Italy from owning submarines, and entry into NATO, following which this clause was allowed to lapse along with many others).
