I'm in the final chapters of "Pickett's Charge - The Last Attack at Gettysburg" by Earl Hess. Excellent book, more history should be written this way. There's very little editorial comment by the author, though we do get a little. For the most part it's facts about the units who were involved in the charge on both sides, a brief description of their commanders and war record up to that point, and descriptions of what they experienced before, during and after the charge. All of this is interspersed with accounts by those who were there that day, describing what they saw. When accounts conflict they are examined against others, and when the author believes that someone's memory has gaps, or that they twisted the facts for their benefit, he says so and explains why he reached that conclusion. There are photos of many of the commanders on both sides, and various maps showing where the units were as the charge progressed. It really is an excellent bit of historical writing.
