Recently while looking through books on the American Civil War on Amazon I came across the title "Gettysburg in Miniature: A Battle Overview Illustrated With Model Soldiers and Dioramas. " Unfortunately there was no picture of the book cover but reading the reviews suggested to me this might be worthwhile. At under $3 for the kindle version down load it was a bargin. I am very glad I did. Once downloaded I could not put it down and finished it in one reading.
