Hamburg Finkenwerder HF 315 & HF 318

[Le Grizzly]

Hi

I am writing you for asking help of Forum members.
I search informations about wreckage of Hamburg Finkenwerder HF-315 (ex Godenwind) and HF 318 (ex Finkwarer).
The Gröner said to have sunk 14 September 1943 in Cherbourg by British aircraft.
Do you have more information about the wreckage site and its condition?
I think they escorted the tug Balidar (http://epaves.grizzly.free.fr/Epaves/Positions_confirmees/14591296.htm) and an other boat, but I am not sure.

Thank you for your help

Best regards

Matthias
