This is a book about the French in Aragon.

If I remember my reading of it correctly, Suchet did well but he was no miracle worker and his enlightened attitude was more one of degree than of kind. He was also only there for a short time.

The interesting thing about the book is how so many things about small war never change. The importance of sanctuary and unified command for example. The French would do well in Aragon and the opposing forces would just go across the border to another province where the French weren't so energetic to recuperate.

Suchet's memoir which is available for free on the net, has a great story in it about a siege of a French post by some insurgents that went on for some period of time. It is amazing, like a movie script and it was led by on French sapper Sgt who was sort of a Gallic Rifleman Dodd.
