Gamble listed numerous fallacies of the book as follows: "Thomas Jefferson was not among the framers of the Constitution (pp. 69–70); Lincoln advised sending freed slaves to Liberia in a speech in 1854, not "during the war" (pp. 16–17); Lincoln was not a member of the Illinois state legislature in 1857 (p. 18); the Commerce Clause was not an "amendment,"; Thaddeus Stevens was a Pennsylvania representative, not a senator (p. 140); and Fort Sumter was not a customs house (p. 242)." Additionally: "In chapter 3, DiLorenzo claims that in a letter to Salmon P. Chase, Lincoln "admitted that the original [Emancipation] proclamation had no legal justification, except as a war measure" (p. 37). His source, however, is the recollections of a conversation (not a letter) that portrait artist Francis Bicknell Carpenter (not Chase) had with Lincoln, and at no point do these recollections sustain DiLorenzo's summary of them. Moreover, in the reference for this section, DiLorenzo misidentifies the title of his source as Paul Angle's The American Reader, when in fact the jumbled material comes from Angle's The Lincoln Reader." He also notes that DiLorenzo claims, for example, "that in the four years between 1860 and 1864, population in the thirteen largest Northern cities rose by 70 percent" (p. 225)." Gamble checks the source and finds it says that total rate of growth took place over 15 years.
