Hello Axel,

1. The F-lighter sunk on 27.07.44 near La Ciotat was F.811 sunk by HM submarine ULTIMATUM.
2. According to the war diaries of Vice-Admiral Lange (Admiral Aegean), GW.03 was torpedoed and sunk 8 miles north of Skiathos on 3 October 1944 (by the French submarine CURIE) while in company with SF.191 and ELENI on passage Chalkis to Salonika. There is no mention of SF.191 being sunk the next day but an omission is possible.
3. GK.06 was not sunk by a submarine. She may have been sunk by HM destroyers TROUBRIDGE and TUSCAN when they raided the Aegean and sank the TONI (638 GRT) on 13 September. Survivors of TONI and GK.06 reportedly landed on the island of Ovo (30 miles NE of Heraklion).

Best regards,

Platon
