The month that saved America
One-hundred-and-forty years ago Saturday, Confederate General Robert E. Lee surrendered to Union General Ulysses S. Grant at Appomattox. Less than a week after Appomattox, President Abraham Lincoln was assassinated. The seeds of a never-ending conflict were planted that month but they never came to fruition and in his book, "April, 1865: The Month That Saved America," author Jay Winik explains how such a tragedy was averted.
