The pages were indeed
both revelant.
I would translate the part we were talking about as :
"On 17 June, the five MS.406s of the
Cours de Chasse flown by de Roquemaurel and his instructors, were sent to Escoublac to protect the
Jean Bart when it departed Saint-Nazaire. During 3 days, they carried a certain number of guard missions and on the 19th, they intercepted 3 He 111s. In the ensuing combat, one of the Morane was hit by french ground fire, which was firing at everything. The fighter was able to land at Escoublac but was too much damaged and had to be left behind."
So Lucien Morareau credits the Aéronautique Navale of 9 victories during the period (7 by the Potez of AC1, AC2 & F1C and 2 by the Bloch fighters of AC3). In an old issue of Aero Journal, Christian-Jacques Ehrengardt give a total of 12 (8 for AC1, AC2 & F1C and 4 for AC3, AC4 & 5AC). But considering the fact there is no real official reccords, I don't think we will have an official definitive number.
Thank you all.
