Frassanito has an analytical mind that defies imagination. (He worked for army intelligenece in the 1960s). His ability to look at old photographs and to extract important historical facts and confirm them with written records is brillant. His goal here is to define the town of Gettysburg and the battlefield as it was in July of 1863. He is not looking for myth, he is looking for facts. These photographs do not lie (unless of course digitally manipulated) as the participants often did. It is a great approch to a major historical battle that answers many questions and raises more. Highly recommended. ( )
