During the Battle of Waterloo, the Prussian army was integral to defeating the French, launching an exhausting march to catch Napoleon's army at the rear. It was a dangerous offensive that would not have happened without the strong leadership of Blucher, who rallied his troops to attack once more after suffering a crushing defeat the day before. But despite his reputation for frontline leadership, the aggressive field marshal had to excuse himself from combat on account of a medical emergency. He was about to give birth -- and here's where we gotta take a bit of a deep breath -- to a baby elephant.
This wasn't just some "Don't ask, don't tell" way of asking fellow soldiers if they would like to see his trunk. Historians agree that in the harrowing two months before Waterloo, Blucher had suffered a schizophrenic episode that had him convinced the French impregnated him with an unplanned pachyderm, despite his physiology, advanced age (nobody's getting preggo in their 70s), and difference in species. He was also getting into fistfights with ghosts, and hopped around on his tiptoes because he believed the floor was lava (his servants had been paid to heat it by the French). To his credit, Blucher knew there was something wrong with his head. It was made of stone, which is why he regularly asked people to hit him with a hammer.
Despite other superior officers knowing of Blucher's breakdown, they considered him such an amazing battlefield commander that the chief of the Prussian General Staff himself wrote that he "must lead though he have a hundred elephants inside of him." They were right to trust the obvious madman, as Blucher managed to lead his forces better than the Duke of Wellington could, striking a decisive blow at Napoleon's troops which led to their retreat. For this he was later granted a sovereign princedom and was decorated officer, which must've made his large grey son very proud.
