David,
I have these two books. Arnaud Gillet did a very good work with its trilogy "Les victoires de l’aviation de chasse française from 10 may to 24 june. His work brought many news infos and the exploitation of many archives give a point of view which can be considered as close of the reality but necessarily accompanied by controversy.
His two last books "Les victoires de l’aviation de chasse britannique - Tome 1 & 2" are did in the same spirit.
Two recensions (in French) are here :
