U-332 Liebe 24-Jun-1942 13 days
On this 70-day patrol Liebe would sink two ships, including the Greek steamer Leonidas M. which he sank on 19 July on his way home from a patrol along the coasts of Cape Hatteras and Long Island, New York. Two officers from the Leonidas M. were taken prisoner aboard the submarine and taken to France – a fate marginally better than being cast adrift in an open boat. U-332 was refueled by U-461 in end July west of the Azores. She returned to La Pallice on the 1st of August 1942 (Wynn, Vol. 1, p.221).
