Who wrote these words about the events at Appomattox Courthouse in April 1865? General George McClellan General Ulysses S. Grant Secretary of War Edward M. Stanton General Robert E Lee

Assuming that this is referring to the same words that were posted before with this question, the correct response would be " General Ulysses S. Grant" since he was writing in his memoirs about the infamous day in which the South surrendered under Lee.
