But to read one man's account, as it happened, and hear his words from the time is amazing. This book is a must-read for anyone who enjoys reading about the civil war. It basically starts after The Wilderness and ends at Appomattox. And General Chamberlain uses vivid wording throughout this book. It is amazing. Answer:

input:  Now, answer this question: Is this product review positive? Title: Should have been good, but it wasn't. Review: This was a disappointment. The hunt for a lost Caravaggio, the digging about in archives, the scientific test to see "is it really?", should be fascinating. But it's not. And I cannot stand non-fiction writers who think they have to make their books read like fiction. Where is the critical analysis? Where is the index? Where are the footnotes? Non-fiction needs references. You cannot expect me to believe what you are writing unless you tell me where you got the information. A bibliography and acknowledgements don't cut it.I'm seeing this more and more in non-fiction and it drives me right up the wall.And who the heck had the idea of publishing a book about a Caravaggio painting with NO, I repeat NO, illustrations?
