“I am asked often about Abraham Lincoln's mistakes and faults; he certainly made some mistakes. I have chapter in President Lincoln about the Powhatan affair that was a royal screw-up in the early days - right alongside the Sumter affair. Lincoln signed letters he should not signed, and the ship was sent to two places at one under two captains etc. Fortunately, no great harm. Lincoln took the blame and did not do anything like that again.”
