Honestly, I found this to be bit dull and lacking in general. What seems like a good idea - a day-by-day "portrait" - is actually better in theory rather than in practice. First of all, it's not an actual chronicle, per se. It's more of a general overview that touches on different aspects of the war as it progresses - letters, speeches, anecdotes, etc. Sometimes it's interesting, but many times it just rambles along rabbit trails that don't really add much to the overall narrative at hand. It's more of a hodgepodge type of gathering that lacks focus and direction, and for this I think it suffers.
I'm not sure if a true day-to-day chronology would be an improvement (or even interesting), but I think it would at least have a centralized theme.
