I still love the cover. And I'm glad to have this useful resource as part of my Russia 1812 arsenal. But the density of movement, location and unit info was, speaking frankly, a real slog to get through, and the writing itself would've benefitted from more editorial intervention (to remedy occasional lack of clarity, frequent repetition, etc.).
 So far only Clausewitz's account of the 1812 campaign has been harder/heavier going.
 One of this book's strengths is the insight into and coverage of Russian command and movement. Where many accounts are markedly Franco-centric, this is pretty evenly balanced.
 Apart from his numerous books and translations, Nafziger is known to many for his unbelievable collection of historical OOBs, which he's made freely available online.
