On 26 May 1828, a teenage boy appeared in the streets of Nuremberg, Germany. He carried a letter with him addressed to the captain of the 4th squadron of the 6th cavalry regiment, Captain von Wessenig. Its heading read: "Von der Bäierischen Gränz / daß Orte ist unbenant / 1828" ("From the Bavarian border / The place is unnamed / 1828"). The anonymous author said that the boy was given into his custody as an infant on 7 October 1812 and that he instructed him in reading, writing and the Christian religion, but never let him "take a single step out of my house". The letter stated that the boy would now like to be a cavalryman "as his father was" and invited the captain either to take him in or to hang him.
