Yes, I had never read this. Not because it is long, but just never had the motivation. A Russian friend requested I remedy that, so I have.
For interesting insights into Napoleon’s war with Russia, it is excellent. For equally engaging thoughts on the human condition, free will, and the like, also excellent. But it is long. And much of the material is difficult to relate to and it ends up being just a story. I hear that it is much better in Russian, as the quality of the prose comes more to the forefront. Alas, since time is finite, I likely will not be learning enough Russian to do this myself.
Overall, recommended if you are interested in this period of history.
