Trudeau's book was excellent especially with regard to the first day. I think it would appeal more to the hard core CW buff though as it is incredibily detailed and the average history fan might find it a bit tedious to slog through. There is another historian named "Rhea" who has an excellent series on the battles which made up Grant's Overland Campaign.
The author is Gordon C Rhea. He wrote “The Battle of The Wilderness, May 5-6, 1864” it was published in 1994.
Until I read the book, I knew little about the Battle of the Wilderness. Rhea’s book was top notch. Incredibly detailed and yet it never seemed to bog down in minutiae.
