Hood's book "Advance and Retreat" has a fair description of the part Longstreet's corps played, as does Longstreet's "From Manassas to Appomattox," with some slight conflicts." William Oates, in Hood's division wrote a fair account of Chickamauga, "The War between the Union and Confederacy", but was wounded early in the Chattanooga fighting. The Georgians are the most poorly reported - the best I've found on them was in UNC's "Documenting the American South," (well worth your reading) in the Houghton brother's book, online. Please keep me in mind, as you encounter such reports in the future. On anniversaries of the battle, I've found many regional newspapers published memoirs of veterans between 1885-1915. Pardon, the poor notations, but I cannot underscore on this word processer, and the spell checker doesn't work either.
