In another patrol in July, U-14 sailed on the north side of the island of Corfu while headed for Santi Quaranta, Albania. Because the harbor at Corfu was occupied by the French fleet at the time, U-14 conducted a ruse de guerre by flying the submarine's former national flag, the French tricolor, in order to pass unmolested.[17] Even though U-14's new conning tower made her look unlike any other Brumaire-class boat,[1] one French patrol plane was successfully fooled by the ruse. When U-14's crew first spotted the aircraft, flying towards them from the direction of the sun, there was not enough time to submerge.
