1918	HMS D4	Sank UB-72
1918	HMS D6	Sank UB-72
1941	Undaunted	Lost HMS Undaunted sailed for her Mediterranean patrol from Malta on 1st May 1941. Ordered to patrol off Tripoli the submarine failed to return on her due date of 11th May and attempts to contact her failed. It is believed that she fell victim to the Italian torpedo boat Pegaso who had sailed from Tripoli on the 12th. At 2030 that evening Pegaso signaled that she had attacked a submarine with depth charges and that a large patch of oil had been observed, indication of the submarines destruction. Against this theory is the fact that by that date Undaunted should have been back in harbour but it is possible that a decision to remain at sea for a day had been taken or that Undaunted may have suffered mechanical problems preventing her return. There is always the every present possibility that the submarine fell foul to a mine.
