Who did Abraham Lincoln appoint as Secretary of War during the Civil War?

Les teaches that when Lincoln needed the right man to be his Secretary of War in the midst of the Civil War, he appointed this man, Stanton. The account describes how Stanton had earlier ridiculed Lincoln, even suggesting that a traveler looking for a gorilla need only go to Springfield, Illinois, and he made other disparaging remarks about him. As time went by and Stanton served under the President, he kept giving him snide remarks and showed no respect for the man whatsoever, but Lincoln never paid any attention to it. Then when Lincoln was assassinated, and after his body had been laid in a side room, Stanton came in and, through his tears, said, "Never has there been such a leader of men." Les uses this to illustrate what made Lincoln what he was: he knew this whole attribute of godly love, and a man like Stanton never phased that love. He continued to work with him, appointed him, and so forth. Les applies it by saying we often do not get immediate gratification, but in the long run what goes around comes around, and our love is still going to be a profitable thing.
