Can anyone help with information on the vessels Wilia (Wilja) or Iskra that left Casablanca for Liverpool via Gibraltar immediately after the French capitulation and just before the British fleet destroyed the French ships laid up in Morocco.

I am particularly interested in personnel who were on board these two vessels and any others which sailed at about the same time on the same route. Most of the people involved would end up serving with the Royal Air Force or the Polish Air Force in Britain
