I have recently discovered that the barn Fritz and his father were sleeping in when he tried to escape is still there, is now a Fritz museum, and has a plaque on the outside reading "Hier blieb auf seiner Flucht am 4/5. Aug. 1730 Friedrich d. Große dem Vaterland erhalten."

Is it just my German being too rudimentary here, or do they sound as happy about the child abuse continuing so Prussia could have a warmongering general as I think they do? (I dug up some pictures of the inside of the museum, and they seem extremely battle-recreation-focused, lending credence to my suspicion.)
