One of his other books "A Writer at War : a Soviet Journalist with the Red Army, 1941-1945" is an excellent, if censored description of WW2 from an eyewitness on the Soviet side.
Its description of the liberation of Treblinka [0] was used at the Nuremberg Trials.
I'll toss in my two cents in support of this recommendation. It provides a great narrative history of the Eastern Front. Somehow Grossman is on the periphery of every major event of the Eastern Front.
This is a wonderful book. The title is a clear play on Tolstoy's masterpiece about the previous invasion of Russia, but so what? I was introduced to it by a dear friend whose father was purged by Stalin so it's doubly poignant.
I still don't understand how a single person could have created a convincing and compassionate portrait for such a wide range of characters. I think this range is much larger than what you have in "War and Peace". An awe-inspiring book...
(I read the book as series of publications in a soviet literary journal some thirty years ago, time moves fast if you come to think of it)
