1st May - She sent her last signal when she reported a large escorted convoy. Italian reports state that one of the merchant vessels reported being attacked by torpedo which narrowly missed the stern of the vessel, it would appear that this was Undaunted.
2nd May - The patrol line was cancelled and Undaunted was ordered to a position north of Tripoli. She wasn't heard from again. She did not return from patrol. It is not known what happened to her.

She was lost during her first Mediterranean patrol off Tripoli being the second U class boat to be lost.

Although the reason for her loss has never been confirmed it is likely that she struck a mine between the 7th and 10th May 1941.
