On the evening of June 13, 1886 — a warm and overcast Sunday — King Ludwig II of Bavaria asked his physician, Dr. Bernhard von Gudden, to accompany him on an after-dinner walk along the shores of Lake Starnberg. Ludwig had been brought to Berg Castle as a prisoner the previous day, deposed from his throne by a government that declared him insane. Gudden was both his doctor and his jailer — a distinguished alienist who had diagnosed the king without ever examining him, based solely on the testimony of servants and ministers. The two men left the castle at approximately 6:30 in the evening. They were expected back by 8 o'clock. They never returned.
A search party found them at 11:30 that night. Both bodies lay in the shallow water near the shore, Ludwig face down in water barely waist-deep, Gudden floating nearby with scratches on his face and a bruised eye. Ludwig's coat and jacket were found on the bank. His pocket watch had stopped at 6:54. Gudden's watch had stopped at 8:00. The official autopsy concluded drowning, but no water was found in Ludwig's lungs — a detail that has fueled conspiracy theories for nearly a century and a half.
The Bavarian government's account was swift and simple: the mad king had attempted to escape by swimming across the lake, Gudden had tried to stop him, and both men drowned in the struggle. Case closed. Except nothing about the evidence supported this story. Ludwig was a powerful swimmer, and the water where the bodies were found was only four feet deep. A strong man cannot accidentally drown in waist-deep water unless he is unconscious, drugged, or held down. Gudden's facial injuries suggested a violent struggle, yet the doctor — sixty-two years old and slightly built — could not have been overpowered by the much larger Ludwig and then coincidentally drowned in the same spot.
Over the decades, alternative theories multiplied. The most persistent holds that Ludwig was assassinated on orders from the Bavarian government or from Bismarck's Prussian administration, which feared the king might appeal to the Austrian emperor for help in reclaiming his throne. In this version, marksmen waited at the lakeshore and shot Ludwig as he waded into the water, with Gudden killed as an inconvenient witness. A fisherman named Jakob Lidl later claimed he had been waiting with a boat on the opposite shore to help Ludwig escape to Austria, and that he heard gunshots across the water. His testimony was suppressed.
Another theory suggests that Ludwig did attempt to flee and suffered heart failure in the cold water — his autopsy noted an enlarged heart — while Gudden suffered a stroke after being struck. A third theory proposes poison, delivered in Ludwig's evening meal, that rendered him unconscious in the shallows.
The truth is that we do not know and almost certainly never will. The Bavarian royal family, the Wittelsbach dynasty, has never granted full access to the private archives relating to Ludwig's death. The original autopsy reports were sealed. Key witnesses were never called to testify publicly. What remains is an image: a deposed king floating face-down in four feet of water on a June evening, his stopped watch reading 6:54, his castle on the mountain standing empty, his throne room forever missing its throne. A hundred and forty years later, the mystery is as deep as the lake.
