According to what I was able to cobble to-gether from published French sources for my
Storks site he was shot down SEVEN times. There is a rather distressing series of photographs showing a badly shot up GG being stretchered away from his Nieuport BeBe having made it back to the field, so that one doesnt count. I didn't note the number of times he is reported to have brought back a damaged machine.
He was the complete opposite of Fonck. Modest, painfuly shy, and heedless of his own safety, but what a fighter. He may not fulfill big Jim's survival criteria, but you might gather I admire him enormously.
