U-504 Poske 13-Feb-1942 12 days
Following the Mamurasinking, Poske turned south, proceeding about 100 miles or more off the coasts of Abaco, Eleuthera, Cat Island and San Salvador. Finding no targets on 14th of March (a month after his arrival) he headed southeast and then east, encountering the British tanker Stangarthon the 16th. There is controversy about whether U-504 or the Italian submarine Morosini sank the Stangarth – it is generally held that the Morosinisank the British ship Manaquion a different date east of the Caribbean – see “Morosini” below.
Furthermore, historian Eric Zimmerman analyzed the original attack reports and concluded that U-504 must have sunk the Stangarth, based in part on the U-boat discovering crates amongst the wreckage labeled “airplane parts- Bombay”. Stangarth was bound to India with military equipment, the Manaqui, a much smaller ship, was heading the opposite direction in ballast and well to the east at a different time.
