I just came across this topic. And I'm French, and I don't want to comment on Napoleon's means, behaviour and achievements

«général en chef» means «commander in chief», so you can keep it as it is in the translation.
EDIT: I just read Cmaq's translation and correction about it. Nevermind.

Apart from that, this is pretty good. The sense of it is very well rendered, and the style you applied perfectly fits.
