Query: Doooo what?

Gary Gallagher has assembled various essayists to compile this latest explanation of the turning point of the Civil War. These 'authors' have added conjecture, opinions, and heresay for this great battle. Mr Gallaghers donation to this work is excerpts from diarists, letters, and newspaper articles of the day. Not one original idea comes from him. There is nothing new here! In fact, the most important factor of this battle, ie. Lost Order #191 isn't even mentioned here. I was disappointed (and I wasn't expecting very much). Instead pick up "Landscape Turned Red" by Stephen W Sears.
