Italian submarine Alagi was an Italian Adua-class submarine built in 1930s serving in the Regia Marina during World War II. She was named after the Amba Alagi mountain in Ethiopia.

History[edit]

Alagi was built in the CRDA shipyard, in Monfalcone. She was laid down on 19 March 1936, launched 15 November of the same year, and commissioned on 6 March 1937.

On May 11, 1937 Alagi was assigned to the 23rd Squadron based in Naples, from where she conducted training in the Dodecanese. During the Spanish Civil War, between 27 August and 4 September 1937, she carried out a special mission. In 1939 she was reassigned for some time to the base in Cagliari and then to Messina. In 1940 Alagi was assigned to 71st Squadron (V Submarine Group) based at Cagliari.

On 10 June 1940, at the outbreak of hostilities, Alagi was on patrol in the waters off Bizerta. She remained on station until June 20 without sighting any enemy ships.

From June 5 to 11 of 1941, Alagi, under command of captain Giulio Contreas, patrolled 20 miles northeast of Ras Azzaz. She sighted a small enemy ship and tried to launch an attack, but it was interrupted by a second ship which detected Alagi and headed in her direction, forcing her to disengage.

At 10:47 on June 12, 1941 while returning to Messina, Alagi was attacked with two bombs and machine guns off Benghazi by a British Sunderland aircraft. The boat's crew responded with anti-aircraft weapons forcing the plane to turn away, probably because it was hit.

On July 18, 1941 she patrolled off of Cape Bougaroun. On July 22 she detected Force H but was unable to attack it, and was subject to anti-submarine search by escorts.

During August of 1941 Alagi patrolled between Sardinia and La Galite Island.

She spent November and December of 1941 patrolling of Cape Fer.

In the late afternoon of January 14, 1942 in the Sicily Channel, Alagi sighted a British naval formation and at 21:05 launched two torpedoes, which did not hit any targets.

On 8 June 1942, roughly 20 nm North of Cape Bon Alagi, under command of captain Sergio Puccini, fired three torpedoes at a naval column (later identified as friendly convoy from Naples to Tripoli). One torpedo hit and sunk the Italian destroyer Antoniotto Usodimare in a friendly fire incident [1] (141 killed and 165 survivors).

On July 12, 1942 at 20:04 in the position 34°59′N 35°32′E / 34.983°N 35.533°E / 34.983; 35.533, northwest of Tripoli, Syria, Alagi fired two torpedoes and scored one hit in the engine room of the Turkish tanker Antares (3723 GRT, 1893) on a trip from Iskanderun to Haifa, causing her to be beached on Ruad Island. The tanker was later re-floated, towed to Turkey and scrapped in late 1943.

In August of 1942 Alagi operated along the Regia Marina and Luftwaffe to intercept and block an Allied convoy to Malta (Operation Pedestal).

On August 12, 1942 at 21:05 in the position 37°28′N 10°38′E / 37.467°N 10.633°E / 37.467; 10.633 Alagi fired a spread of 4 torpedoes against a merchant and a cruiser, and immediately dove. 3 explosions were heard. At 21:12 cruiser HMS Kenya was hit forward by one of four torpedoes and sustained damage to bow structure. HMS Kenya was able to make 25 knots and remained with the convoy to continue operating in defense of merchants. The other 2 torpedoes hit and sunk M/V Clan Ferguson which was previously damaged by a bomb from Ju-88.

In January of 1943 Alagi patrolled northeast of ​​Bona.

From February through June of 1943 she conducted several patrols south and southwest of Sardinia.

In July of 1943 Alagi first patrolled south of Sardinia, and later provided defensive screen in the waters of Sicily. On July 16, at 6:13 in the position 37°02′N 15°55′E / 37.033°N 15.917°E / 37.033; 15.917 she intercepted a column of three destroyers. Alagi launched three torpedoes while on surface. After a minute and 45 seconds a violent explosion was heard, but no information about this action was ever reported in British official documentation.

Alagi, a member of the 7th Group - 71st Squadron of the submarine fleet, was still operating on 8 September 1943, when the Allies and Italy signed the armistice. Alagi arrived in Malta with the rest of Regia Marina fleet.

In October of 1943, Alagi was transferred to Haifa where she was employed as a training unit for British troops and as a shipping vessel for supplies to the Aegean Islands. She returned to Taranto in December of 1944, where she remained inactive until the end of the war. She was sold for scrap on 1 February 1948.
