God knows what you were reading. “Lee for Dummies”, maybe.
Well, let's see.
On Gettysburg I've read Harry W. Phanz's three volume study on the battle, "Gettysburg" by Stephen Sears, "Gettysburg; A Testing of Courage" by Noah Andre Trudeau, "Retreat from Gettysburg: Lee, Logistics, and the Pennsylvania Campaign" by Kent Masterson Brown, "One Continuous Fight: The Retreat from Gettysburg and the Pursuit of the Army of Northern Virginia, July 4-14, 1863" by Wittternberg, Petruzzi, and Nugent. On Lee I've read Douglas Southall Freeman's biography of Lee as well as his "Lee's Lieutenants", "General Lee's Army: From Victory to Collapse" by Joseph Glatthaar, "Reading the Man: A Portrait of Robert Lee Through His Private Letters" by Elizabeth Brown Pryor, and "Robert E. Lee" by Noah Andre Trudeau. Never hear of "Lee for Dummies".
How about you?
