Many battles are decided not just by clever strategies, but often by mistakes made by the opponents. Out of every dozen battles, only one might be won through a brilliant plan, while others depend on errors or misjudgments. Success in warfare frequently hinges on the errors or oversights of others rather than exceptional tactics.
"One battle in twelve might be won by a brilliant military stratagem. The rest stood or fell by somebody's blunders. Only rarely, there came the feel of a great campaign evolved by a stylist: imaginative, comprehensive, irresistible." This quote highlights how rare truly masterful strategic planning is, emphasizing instead the importance of mistakes and occasional exceptional campaign design for victory.
