Tricheco was cruising off the coast of Brindisi, coming from Augusta (Sicily), when she was attacked by the British submarine HMS Upholder. The Tricheco was hit by a torpedo and sank rapidly. Source:

Saint Bon sailed from the base of Taranto heading to Tripoli (Lybia) via Northern Sicily, carrying a dangerous cargo of more than 150 tons of ammonitions and gasoline. On January 5, the
Saint Bon was intercepted and torpedoed off Capo Milazzo by the British submarine HMS
Upholder. A torpedo hit the starboard side of the
Saint Bon, and the gasoline cargo exploded, devastating the Italian submarine, that sank rapidly. Just three survivors could be rescued by the British crew. Source:

Hermione spotted and attacked an enemy submarine off Malta. The partrol zone was that of
Tembien. The cruiser rammed the submarine, that sank immediately: no man of the crew could be rescued.The

Upholder. Source:

Hero of the Upholder By Jim Allaway indicates that the HMS Upholder sank 2 U-boats and damaged another:
Descripton: This is the story of the Royal Navy's top submarine ace. In the 16 months that HMS Upholder operated in the Mediterrean, Wanklyn sank two U-boats and damaged another, damaged a cruiser and a destroyer, and sank or damaged 19 supply ships totalling 11,000 tons. Upholder was lost with all hands off Tripoli in April 1942 after a brilliant career. Source:
