Yes! I am interested! This part of history is very important for my research.

I found this piece of reminiscence on
"The Luck of Thirteen
Wanderings and Flight through Montenegro and Serbia"

Pg 373 ...

The Harmonie, empty of cargo, was like an eggshell in the water. She bounced and rolled and bounded from wave to wave, half of the time her screw out of the water. The breakfast did not nourish many. Far on the horizon could be seen the destroyer and the cruiser sweeping in gigantic circles.

Half a kilometre away a periscope suddenly appeared, then the submarine dived, rose once more, showing the rounded conning tower, dived, rose again, like a porpoise at play.

"See," cried the sailors, "how well are we guarded. Outermost the cruiser, then the destroyer, and innermost the submarine." The cruiser and destroyer took big sweeps once more and steamed off behind us towards Cattaro.

Till now we know that these ships sunk in San Giovanni di Medua:

1. Giovanni Benedetto
2. Triara (or Thyre) (french or greek?)
3. Unione (a small italian ship)
4. Brindisi
5. Andrassy

The last was positively identified. Meanwhile, there are 2 wrecks about 2 miles from port (one inside the gulf, the other on the entrance of the gulf), but I did not succeed to positively identify them.
