Italian submarine Luigi Torelli

Italian submarine ''Luigi Torelli'' was a of the Italian navy during World War II. The vessel operated in the Atlantic from September 1940 until mid-1943, then was sent to the Far East. After Italy's surrender in 1943, the ''Luigi Torelli'' was taken over by Nazi Germany's ''Kriegsmarine'', then, in the waning months of the war, the Japanese Imperial Navy. It was one of only two ships to serve in all three major Axis navies, the other being the Italian submarine '' Comandante Cappellini''.

Construction

''Luigi Torelli'' was built at the Oto shipyard in La Spezia, Italy. One of six boats of the ''Marconi''-class submarine, which were laid down on 15 February 1939, ''Luigi Torelli'' was launched on 6 January 1940. Designed as an ocean-going vessel, she was intended for operations both in the Mediterranean and in the Atlantic.

Service history

When Italy entered World War II in June 1940 the ''Luigi Torelli'' was still completing its training and shakedown period. Afterward, it conducted a short reconnaissance mission in the Gulf of Genoa, and was then dispatched to the Atlantic to Bordeaux in occupied France to serve in the Italian submarine flotilla there.

Between 11 and 29 September 1940, the ''Luigi Torelli'' was assigned to patrol an area just off the Azores Islands. On 5 October 1940, she reached Bordeaux. In the following weeks, the boat left port several times and made short practice missions.

On 15 January 1941 ''Luigi Torelli'', under the command of Primo Longobardo, sighted a small convoy and sank the Greek vessel ''Nemea'', the Norwegian vessel ''Brask'' and the Greek vessel ''Nicolas Filinis''. A fourth vessel was also damaged, but escaped due to the foul weather.
This was one of the few examples of an Italian submarine achieving great results while participating in a Wolfpack attack, according to Regia Marina Italiana.
Two weeks later, the ''Luigi Torelli'' sank the British vessel ''Urla''. In July 1941, she sank the Norwegian tanker ''Ida Knudsen''. A year later, she sank the British vessel ''Scottish Star'' and the Panamanian motor tanker ''Esso Copenhagen''.

The ''Torelli'' was the first submarine to be attacked by an Allied Vickers Wellington using the Leigh light, on the night of 3 June 1942 at roughly off the Spanish coast, suffering considerable damage but managing to reach the port of Avilés and, after an attempt to reach Bordeaux ended when an Australian Short Sunderland attacked the submarine and inflicted further damage upon it, it ended up in Santander; after emergency repairs, the submarine managed to exit the port (where the Spanish authorities intended to intern it) with a stratagem, and safely reached Bordeaux on July 15.

In 1943, the ''Luigi Torelli'', after surviving at least two serious air attacks, was one of seven Italian submarines designated to be converted into transports. The Italian boats, due to their dimensions, were deemed better suited for long voyages to the Far East on missions to acquire precious and rare material. The ''Luigi Torelli'' left for the Far East on 14 June 1943. The operation was under German control but the ''Luigi Torelli'' retained its Italian crew.

The ''Luigi Torelli'' was one of three Italian submarines in the Far East in 1943 when the new Italian government agreed to an armistice with the Allies. Of the three, the ''Luigi Torelli'', '' Comandante Cappellini'' and ''Giuliani'' and their crews were temporarily interned by the Japanese. The ''Luigi Torelli'' and two other boats then passed to German U-boat command and, with mixed German and Italian crews, continued to fight against the Allies. The ''Kriegsmarine'' assigned new officers to the ''Luigi Torelli'', renamed her the ''UIT-25'' and had her take part in German war operations in the Pacific.

Following the German surrender in 1945, the ''Luigi Torelli'' was again given a new name, the ''I-504'', by the Japanese, and operated with the Imperial Japanese Navy until 30 August 1945. The ''Luigi Torelli'' and sister submarine ''Comandante Cappellini'' were the only two ships to fly the flags of all three main Axis powers during World War II.

As the ''I-504'', ''Luigi Torelli'''s crew claimed to shoot down a B-25 Mitchell bomber while under the Japanese flag near the very end of the war in the Pacific, allegedly the last success by an Axis naval vessel in the conflict.

Fate

Captured by the U.S. in Kobe, Japan, at the conclusion of the war, the ''Luigi Torelli'' was scuttled by the US Navy in the Kii Strait on 16 April 1946.
