Ender's Game - Wrong Commander
On Page 177 of the Author's Definitive edition (Ender's army's first battle), Ender realizes that "Everyone had learned the wrong lesson from BONZO's misuse of Ender Wiggin" by streaming through the door too quickly, while he would wait and size up the opponent. The only problem is that Bonzo wasn't the one who made Ender jump through the gate before everyone else. Rose de Nose was the one who did that. The mess up is found in the first and second editions of the book as far as I know.
