Nearly 75 years have passed since the sinking of Aldebaran (code AL), an Italian warship, which met her fate at 9:40 in the morning of October 20, 1941 and was discovered and positively identified by the diving team of Antonis Grafas in 2014.

The spectacle that the divers saw, the first people who set their eyes upon the once majestic "Torpediniera", a 82-metre long wreck, for the first time since her sinking, has brought again to the surface the tragic events that unfolded on this fateful morning of 1941, a forgotten episode of World War 2, that remained lost at  a depth of 107 meters below sea level near the islet of San Georgio.

"Every shipwreck is a window into history" Antonis Grafas, an experienced deep diver and the leader of the research group says and adds:

"From the first moment I saw the wreck I realized that this is a ship with great historical significance. The satisfaction and pleasure that I felt were unique emotions."

Discovery and identification of the wreck

The cause of the sinking of "Torpediniera" (roughly equivalent to a Destroyer) Aldebaran (AL) was a mine laid by the British Submarine HMS Rorqual.

The minefield did not only destroy Aldebaran but also sunk her sister ship Altair, which also struck a mine in the same minefield a day before at 19:28 on October 19, 1941 and sank while she was being towed towards the port of Piraeus, at the southeast of the island of Patroklos Island the spot of one of the biggest naval tragedies, with 4,000 Italian POWs drowned in 1944.

According to British archives the deadly trap, the laying of the minefield that would sink  the two Italian ships twelve days later, the Aldebaran and the Altair, was set up on 8 October 1941.

The experienced deep scuba diver and underwater photographer Kostas Milonakis describes the moment of this historical discovery: 

"The sonar had shown a little "lift" on the bottom and I was quite skeptical about what we would see at a depth of 107 meters. 

When I began to see the wreck, I took a deep breath of satisfaction and immediately after I saw the big guns of the ship at the stern. 

It was the ship we were looking for! 

I immediately prepared my underwater camera and made a sign to my fellow diver Yannis Liardakis to enjoy this unique spectacle! 

I enjoyed it more than any other dive in my life so far! 

We found a warship lost in time and we were the first people to see her after 73 years at the seabed."

The field research proved that this is the wreck of a torpedo ship  (Torpediniera), of the Italian Royal Navy, (SPICA class, PERSEO type).

This assessment, combined with historical and photographic sources further indicated that this is obviously the wreck of the Aldebaran, which, according to the Italian Navy Directorate of History, sank at 9:40 in the morning of 20 October 1941, approximately three nautical miles north-northwest of the island of San Georgio, after hitting the allied minefield in that region, laid on October 8, 1941 by the British submarine HMS RORQUAL.

According to the Italian Ufficio Storico della Marina Militare, "the ship had sailed at midnight on October 20, 1941 from the port of Piraeus, with orders to assist Lupo to tow Altair, which struck a mine on the previous day. 

Moreover Aldebaran had the order to investigate for any survivors aboard the bow of Altair and during this research Aldebaran struck a mine, which exploded beneath the hull. 

The ship, partly flooded and with a broken keel, floated for more than half an hour before it capsized and sank."

There are conflicting reports about the number of victims of the sinking of the Aldebaran

The Italian sources mention that out of her 150 crew, seven were killed and three died due to their injuries. 

German sources indicate that 14 were lost and 140 crew members were rescued, including fifteen injured.
