 L.135 finally sinks the sub while the 27 survivors were clinging to the two planes now floating, to be finally saved by the alarmed "Tb 100M".This was the first sinking of a submarine by airplanes in naval war history.The very same day, the French submarine "Ampére" scored two torpedo hits on the Austro-Hungarian Hospital ship "No I" (the former Lloyd steamer "Elektra") off Cape Planka (Rat Ploca), causing two fatalities.
