We have little information about No.615 Squadron during the month of April 1940. The ORB summarizes to a single page with only two entries (April 1 – April 12 and April 27), and the documentation is very limited . However, some events can be noted.
First of all, the Squadron leaves Vitry-en-Artois on 12 April to reach Poix. At the same time, the B Flight remains at Saint-Inglevert in order to ensure the usual patrols. The presence at Poix is, however, of short duration since, on 27 April, a new trip takes place in the direction of Abbeville. On the same date, the first Hawker Hurricane Mk I finally arrived and the transformation could begin.
