On what dates before D-Day did the British ace J.E. “Johnnie” Johnson personally lead the Spitfires of 144 Wing of 441, 442 and 443 Squadrons, RCAF, from RAF Ford, on dive-bombing missions against ground targets in France ?

He describes leading one such mission (which included having to have a pilot fished out of the Channel by a Walrus) at the conclusion of chapter 13 of his classis memoir WING LEADER.

The wing flew a large mission against V-1 sites on 28 May and a radar site on 5 June.

Does anyone know which mission Johnson’s description refers to and what the results of it were?
