What has always bothered me about Sickles is that when he was wounded he returned to Washington ahead of the Army and immediately attacked Meade and tried to take credit for the victory himself despite his blunder in the Peach Orchard.
Although I’m only a couple of chapters into the book, it seems like exactly the kind of thing he would do. The book is called “American Scoundrel” for a reason!
He does, however, deserve credit for getting the enabling legislation for Central Park through the NY state legislature.
