Book excerpt: Little happened in 1859 that would have told Americans there were on the precipice of a continent-wide war and the end of the most powerful slave society in the world. Yet, within eighteen months of the end of 1859 conflict descended on the nation and familiar characters were playing unfamiliar roles. Robert E. Lee was in command of troops at Harpers Ferry. Tom Jackson was a math professor at VMI, though he will lead cadets to ensure order at the hanging of John Brown at the very end of the year. Sam Grant was a bill collector in St. Louis, and "Cump" Sherman was heading a military school in Louisiana. Jefferson Davis was a senator, and Abraham Lincoln was a successful lawyer and failed senatorial candidate.
