Vlad III, Prince of Wallachia:
One of history’s most notorious bad boys, Vlad the Impaler aimed to scare off the Ottoman troops, and boy did he ever. While the Ottomans were marching toward the capital of Transylvania, Vlad left around 20,000 slain Turks and Bulgarians that he impaled on the path to the capital. The plan worked. The Ottomans saw exactly how crazy this dude was and ran the other way.
These examples of unorthodox tactics should be a reminder to any military leader that you have to think outside the box, especially if the odds are against you. If your seemingly crazy plan works, you will be considered a genius.
