Nice tonic to the rah-rah British perspective of some Waterloo histories. *Extensive* quoting from diaries and memoirs by French officers and soldiers open up that side of the battle in a way I had not read before. Excerpts by British and Prussian participants help round out the picture, which is not as simple as "Napoleon was on top of things/Napoleon was not all there." For a fiction writer who only poorly reads French, these first-person excerpts are gold.
Chapters are well organized and build on each other. Field explains military tactics and strategy well enough for me to see the reasoning behind some of the moves that seem, from the British perspective, mysterious. Maps very helpful.
