Thank you, Jempie. I now know a little more. But to explain my use of the word RAID; I presume it means the same in French as in English.
I found reference ro Bregi's Fen flight in an Archive digitisation at Nat Arch of Aust.
www.naa.gov.au /recordsearch <breguet aeroplanes ltd>
The Series number is A289 Control number 1849/8/227
but just using Breguet, or Breguet Aeroplanes Ltd as a keyword will get it for you.
On page 6 of that file , beneath Motors, I find,
" Henri Bregi made his famous raid from Casablanca to Fen"
Checking through a search engine it looks like a postage stamp was issued in honour of this flight. It also seems that it was a postal delivery flight, too.
So, was Bregi's flight with mail, or bombs for rebels? That word RAID has me wondering.
