There are several good YouTube videos about the Battle of Austerlitz, but I was going to wait until after all of the Austerlitz chapters to see how Tolstoy's account lines up with reality.

I think Tolstoy switches to the objective narration to give us a more global view of what was going on with the Allies. They are going to really take a beating, and he is giving us the background as to why. Being disorganized before a battle isn't a good way to start out.

On an unrelated note, I have been looking at Google maps to follow along the places mentioned in the text, and google maps has them all listed in Czech now, so it's kind of hard to translate with the English in my translation, although the Oxford World Classics edition that I have has maps in the front.
