Since my mother tongue is french, I guess I didn't choose the proper english word. In the context of an attack we sometimes see the "fight or flight" response. But I don't know what is the best term to translate "fuite" in this context.

"Flight" is used in English to mean "an act of fleeing". It's perhaps less common outside of specific idioms ("fight or flight" being one of them, yes), but people will generally understand you correctly in context. It seems from the rest of the comments that GP is also not a native English speaker.
