The only downside that could, to the untrained reader, be criticized, is this tumultuous history of France in which evolves the gendarmerie and that can quickly be confusing for incomplete in this area: to make the most of the work, I I read it and take notes with the help of internet. This is perfect for someone who prepares a general knowledge competition and will consider this book as a work tool, but if you are just interested in the history of the gendarmerie, surely you would take more pleasure in reading after a refresher on the different periods of the French early modern period to the present!
I highly recommend.
