Yes the five first Squadrons mentioned were all targeted against Mont Fleury. The other Squadrons of No. 4 Group were dispatched against Maisy [there's actually a memorial at Grandcamps-Maisy, which was unveiled circa 1994, for the french heavy bomber Squadrons, 346 and 347 from Elvington, the former having operated against that target that night.

101 attacked primary, 5 were abortive not above enemy territory, 4 failed to start.

The other coastal guns were attacked by other groups. I know Houlgate was attacked by No. 7 Squadron, but this unit was a pathfinder.
