ORP Dzik (Lt.Cdr. Romanowski) fires torpedoes in Bastia harbour, Corsica, France and sinks the German tanker Nikolaus (6397 GRT, former Greek Nicolaou Ourania) and the German tug Kraft (333 GRT). Dzik also calimed the sinking of three German landing craft, normally identified as SF 172 (130 GRT), SF 176 (130 GRT) and F 420 (220 GRT).

However, it has been established that SF.176 and S.110 were both lost in the explosion of their ready-use ammunition in the air attack and Dzik had no part in their loss, while SF.176 was sunk in action against MGB.658 off Elba on 15 October and possibly not even present at Bastia that day.
