In July 1941, a British submarine sank an Italian submarine in the Mediterranean Sea.
It was against this backdrop that the Royal Navy submarine HMS Torbay and the Italian submarine Jantina squared off in the Aegean Sea near the island of Mykonos.
The first two passed in front of the Italian sub, but the next struck it and exploded.
The Italian sub sank quickly, and only six of the 48-man crew survived, swimming to a nearby island.
By the end of the war, Torbay had sunk more than 40 German, Italian, and Japanese warships, merchant ships, and other vessels.
