11 May 1940
There is little information regarding No.615 Squadron activity during this day, except for the mention of patrols between Abbeville and Le Touquet . It is likely that the lack of pilot training, the transformation on Hawker Hurricane Mk I, and the low number of available aircraft have helped keep the unit in second lines.
