Thank you Siri, but I already knew this site.

There are some differences..
The page writes that the Empire Seaman was sunk as blockship in the English Channel. Jordan writes she was sunk as blockship in the Orkneys and Rohwer writes that she was a victim of U-52.



Another problem:
The British steamer Tower Field:
Jordan writes that the ship was bombed on 10.05.41 and was repaired as Empire Tower. The page you have mentioned writes that the ship stranded on 19.10.41 and was repaired as Empire Tower. Who is right? Perhaps both?

Regards
