As Ned has suggested, this dissertation contains both "opinion" and "misrepresentation."
The Lew Wallace section is full of nonsense, such as Wallace supposedly getting on the bad side of Grant, Halleck, and CF Smith in late '61 for a flag incident, thus sealing his doom. In fact, Wallace was promoted and given command of a division well after this, and he wrote fondly in his autobiography of CF Smith personally helping him become more skilled in the military arts.
The author needs to read Wallaces own account of how he got on Hallecks bad side... and it did not happen until well later, on the approach to Corinth.
